In this guide, I am going to answer all questions about the Rockwool sandwich panel.
Whether you want to learn about fire resistance capability, design, insulation, thermal properties, limitations or characteristics, you&#;ll find everything here.
Keep reading:
A Rock wool sandwich panel is an insulation material constructed from stone wool that is enclosed between two metal sheet surfaces.
The stone wool has a high density with exceptional compression, and tensile strength which makes it suitable for constructing buildings.
Figure 1 Rockwool sandwich panel
Rockwool sandwich panel will offer you numerous advantages over other insulating materials.
Some of the benefits of Rockwool sandwich panel include:
Rockwool has outstanding thermal resistance properties which will enable you to reduce the energy bills spent on heating, and cooling your building.
You can use Rockwool in places like meeting rooms or offices in busy towns to reduce noise nuisance.
The material can trap sound waves, and deaden the vibration due to random fiber orientation, and high density.
The material has good fire resistance properties and is suitable for constructing safety buildings that require fire protection.
Using the Rockwool sandwich panel to construct your building will greatly improve its capability to protect life, and property in case of a fire outbreak.
You can use Rockwool if you want to minimize risks of bacteria and mold infestation inside the building. This is because Rockwool provides room for moisture escape in the construction.
Using Rockwool for constructing your buildings offers you a durable property that will serve you for a very longtime because of the unlimited lifetime of the material.
The durability of the material reduces the cost of maintenance, replacements, and repairs.
Rockwool sandwich panels are very firm, and not easily damaged through compression.
This makes it suitable for constructing buildings whose layout or use may change with time, and require additional portions as well as thermal insulations for domestic buildings.
The material reduces carbon footprints thanks to its natural origin and hazards free rating.
Besides, using Rockwool sandwich panels reduces air pollution because you will not heavily rely on non-renewable energy sources like electricity, and gas.
The materials for making a Rockwool sandwich panel is naturally sourced and can be recycled over and over again.
You can use old Rockwool sandwich panels to construct new panels when the building has served its purpose, and therefore reducing the cost of production.
You can use fast to install Rockwool sandwich panels that are producedfollowing the layout of your building drawing. Hence, you will shorten the installation period with more than 40%.
The main disadvantages of a Rockwool sandwich panel include:
Rockwool sandwich panels can be used in many industries for building the roofing, walls, modular buildings, and construction enclosures.
You can also use Rockwool sandwich panels to:
However, the material is most suitable for the construction of cleanrooms, pharmaceutical and electronic industries most
Yes, Rockwool Sandwich panels can withstand temperatures above °C, and the core material itself is non-combustible.
The material&#;s high density will stop the fire from penetrating the fibers, prolonging the spread of fire to enable people to leave the building.
Figure 2 Rockwool panel
The Rockwool sandwich is composed of surface material and the Rockwool filling material.
You can select Rockwool sandwich panels constructed from PPGI or galvalume steel
Galvalume steel coating consists of aluminum, zinc, and silicon to protect the underlying metal (steel) from oxidation.
The components ratio in galvalume steel is 50% zinc, just under 50% aluminum, and traces of silicon.
It helps the metal resist rust, and offers enhanced long-term protection when exposed to a fluid which increases the speed of oxidation compared to normal galvanizing.
This type of coating is best suited for metal paneling, and roofing for outdoor applications since it can withstand intense corrosion than standard galvanizing.
However, you should not use galvalume steel in an alkaline environment because the aluminum in the coating is less stable under such conditions.
The cut edges of galvalume steel are more prone to corrosion given that the honeycomb structure of the coating of the steel provides insufficient protection to exposed edges.
When corrosion occurs in galvalume steel, it will spread from the point of original contact whereas the corrosion remains localized in PPGI coating.
You should also avoid using this type of steel in an application where the chances of damages, scratches, and indentation are high.
These are pre-painted galvanized iron steel. The coating has an evenly distributed layer of zinc cover which protects the underlying steel sheet from oxidation and rust.
The steel that has this type of surface treatment is very durable and highly resistant to attack UV sunlight rays and weather.
Rockwool is wool manufactured from molten rocks which include a mixture of anorthosite, basalt, and cemented briquettes. You can also make Rockwool through melting basalt, dolomite, diabase, and combining them with Bakelite.
The rocks are subject to heat overabout °C to melt the rock mixtures and spun them into fibers. The spun rock wool is stabilized through adding a mineral oil and a binder, which also makes it water repellant.
A good Rockwool panel should possess the following features:
Figure 3 Joining rockwool panel
Yes, the length of the Rockwool sandwich panel is limited to the size of shipment vessels, which can only house 11.85 meters.
The standard width of the panels is usually mm while the thickness can vary from 40mm to 200mm.
However, you should use panels that are less than 4 meters that are easy to handle and move around without bending.
When your requirements exceed 4 meters, insert internal steel bars to reinforce against bending.
When installing a Rockwool sandwich panel, you must take the following precautions to ensure good installation and safety to installing personnel.
When installing roofing, follow the following steps:
Figure 4 Rockwool panel
For wall installation, observe the following:
When installing the panels, insert a spacer between the base drip and steel-cut edges of the panel to prevent corrosion from starting and spreading from the edges.
The thickness of surface galvalume steel or PPGI steel can range from 0.4 to 0.8 mm while that of the whole Rockwool sandwich panel will range from 40 to 200 mm.
The thicker the Rockwool sandwich panel, the more efficient the insulation.
Noise insulation provided by Rockwool sandwich panels isdue to the structure of fibers. They possess a characteristic high sound absorption coefficient over a very wide range of frequencies.
The fibers have an orthogonal arrangement towards the sheets.
They are also very densely compacted to achieve monolithic blocks which are perfect for the absorption of sound.
You can also include an internal steel sheet that has been micro-perforated to enhance the sound absorption properties and reduction of reverberation.
When you lineyour room with a Rockwool sandwich panel, you can reduce the sound by more than 10Db and further reduction is dependent on other details of the room.
You should use select Rockwool sandwich panels when your main aim is to insulate against fire and sound.
Rockwool has the best fire performance of all the insulating materials and can achieve up to 4 hours of fire resistance, which is sufficient enough to allow people to leave the building.
Similarly, it is perfect for insulation against sound and is fundamental for applications that need to be soundproof such as television and radio studios among others.
Figure 5 Rockwool sandwich panel
The price of a Rockwool Sandwich panel will vary to the following factors;
PUF is an acronym for polyurethane foam insulation which you can construct through filling the void of the insulating material by an insulating gas/air.
When you release the pressurized PUF sprays in the insulating region, they mix with air and solidifies, a process that traps numerous air pockets inside the solid.
On the other hand, Rockwool is constructed from stone fibers.
Rockwool is heavier and more densely packed than PUF insulation.
As such, Rockwool offers higher fire resistance and more temperature tolerant compared to PUF.
PUF insulation also has a high resistance to water absorption and low permeability to moisture compared to Rockwool.
In terms of thermal insulation, PUF offers superior thermal insulation compared to Rockwool sandwich panels.
Figure 6 Sandwich panel production
Production of commercial Rockwool sandwich starts from heating basalt rocks and other raw materials at °C.
The molten rocks are then subjected to air or a current of steam.
You can add oil to during the production process to reduce dust formation.
The molten rock is then rotated in a spinning wheel at a very high speed, producing a finished fibrous product.
An automatic machine uncoils the inner and outer sheet layers. The Roll forming machine designs the sheets to the desired shape for either roof or wall panels.
You then cut slabs of Rockwool into filler strips and feed them between the sheets when making the sandwich panels.
For roof panels, you cut the slabs into trapezoidal shapes that fit them.
Run the sheet layer through a preheating station to obtain a uniform reaction.
Apply the appropriate amounts of components using two or multi-component high-pressure metering machines.
An oscillating coating gantry then evenly distributes the foam mix.
The reacting foam moves to a double belt where the foam cures in a slat conveyor visible as a continuous moving mold.
Using a cross cutter, cut the endless formed sandwich ribbon into the desired length and set it to cool in the conveyor.
Stack the cooled panels on pallets and wrap them using a PVC foil then deliver it to the customer.
The whole production unit should be automated and control systems configured to ensure uniform and constant product quality.
A superior quality Rockwool sandwich panel should have ISO, TS EN, and CE quality certificates.
The fire protection qualities of the Rockwool are tested and classified according to TS EN -1, A2-s standards.
Similarly, the product specification should meet the specifications of TS EN which deals with self-supporting double skin metal faced insulating panels.
Rockwool has been classified by the International Agency for Research on Cancer under materials that are not classifiable as to human carcinogenic.
However, exposure to dust from Rockwool can cause temporary skin irritation which can be very discomforting to personnel working with it.
As a standard practice, you should always observe these safety measures to avoid any discomfort from Rockwool dust:
Figure 7 Assembling rockwool sandwich panel
A Rockwool Sandwich Panel comprises of steel sheets that are either galvanized or galvalume.
The core is constructed using different types of natural materials including:
The efficiency of Rockwool in thermal insulation is determined by the following factors:
This parameter is expressed as (W/mK) and is the measure of how heat is transferred through the Rockwool core.
You should consider selecting a material with very low thermal conductivity for enhanced thermal insulation.
This is also known as the R-value and is calculated as thickness (m) divided by conductivity (W/mK).
This measures the ability of the Rockwool to resist heat loss per unit thickness.
Thicker Rockwool core has lower heat conductivity.
When considering the R-value of the material, also consider the specific heat capacity, density and weight of the material to help you maximize the insulation abilities of the Rockwool.
A Rockwool material with high specific heat capacity will absorb more heat with an increase in temperature.
The density of a material is measured as material mass per unit volume. A good Rockwool core should have a high density which supports high thermal mass and results in low thermal conductivity.
To work out thermal diffusivity, you will use the formula: Thermal Conductivity / Density x Specific heat capacity.
This parameter will let you know the ability of the Rockwool to store thermal energy in comparison to its ability to conduct it.
The lower the figure, the better the performance of the Rockwool sandwich panel as an insulator.
You can use this method as provided under ISO 834 to test and rate the performance of different Rockwool materials in withstanding similar levels or intensity of a fire.
The curves will indicate how long it takes to reach the maximum temperature and how long the Rockwool sandwich panel can hold its stability.
A Rockwool sandwich panels can last the service life of your building when you do proper installation and maintenance.
Yunsheng contains other products and information you need, so please check it out.
The panels can maintain their original fire protection, insulation, and acoustic properties incase no physical damage affects them.
Yes, you can use old Rockwool sandwich panels to construct new panels since a Rockwool comprise of products from natural sources.
Likewise, one of the construction materials for a new Rockwool sandwich panel is a recycled steel slag. The recycled content can vary from 16 to 40% depending on the manufacturing factory.
The number of recycled materials should be optimized to achieve the best fire, thermal and acoustic properties at maximum allowable recycled content.
The main difference between the two Is the composition of core material used for manufacturing and their functional abilities.
Figure 8 PU Panel
A Polyurethane Sandwich Panel is constructed using a polyurethane foam which is a polymer comprising organic units linked by carbamates.
When the molten foam contacts air it solidifies and sticks on to the metal sheets that form the internal and external surfaces.
It forms a monolithic insulating material with high insulating capabilities.
On the contrary, a Rockwool sandwich panel is constructed from an assortment of natural rocks treated to temperatures of about °C.
The main functional difference includes:
i. Insulation Value
Polyurethane Sandwich Panels have a higher insulation value compared to a Rockwool sandwich panel.
For instance, you will use a Rockwool sandwich panel that is about 80 mm thick to achieve the same level of insulation that is provided by a 50mm polyurethane Sandwich Panels.
ii. Fire Protection
Rockwool sandwich panel is by far the best material to use when you want to achieve maximum resistance from fire.
In contrast, the organic nature of polyurethane makes it susceptible to burning and will, therefore, fuel the fire rather than resist it.
iii. Acoustic Properties
The Rockwool panel has superior noise insulation properties compared to polyurethane Sandwich Panels thanks to the structure of their fibers.
iv. Weight
Rockwool has more weight compared to polyurethane which makes it a bit challenging to handle and install.
A Rockwool Sandwich Panel has to contain Rockwool as the main insulating core.
There are both wall and roof Rockwool sandwich panels for construction or cladding of walls and roofs respectively.
Sandwich Panel roof can comprise an assortment of insulating material as long as the desired insulation needs are met.
You can select from sandwich panel roofs with corrugated upper sheets or with rabbets.
When sourcing for these panels, you should take note of the following:
Polystyrene (PIR) sandwich panels comprise a polymer that has been impregnated with a foaming agent.
The foaming agent is exposed to steam to form a cell structure that is uniformly closed with great insulation properties.
Polystyrene has superior insulation properties per unit core compared to a Rockwool sandwich panel.
Breathability, also commonly referred to as vapor permeability, has gained a lot of emphasis as a key property in wall insulation.
Rockwool has a very low resistance to diffusion and supports easy penetration of water vapor without an obstacle while PIR supports negligible vapor penetration.
However, the high vapor permeability is not a disadvantage nor an advantage in itself.
The main issue is to avoid the condensation of water inside the wall should the temperature drop.
Rockwool core has more weight compared to sandwich panels composed of PIR cores and therefore requires more experienced personnel to handle and install.
There is a wide difference between polystyrene and Rockwool in terms of water absorption.
In case of exposure to water, the PIR core will repel water and dry very quickly, therefore, offering at most protection against water.
On the other hand, Rockwool is very susceptible to water, and soaking is unacceptable.
When installing the Rockwool sandwich panels, ensure that you seal off all avenues of possible water ingression.
Rockwool sandwich panels rate as class A1 to BS under ISO -1 and therefore the best material so far for insulation against fire.
Ifa fire breaks up, the material will emit a negligible amount of fumes and smoke, slowing the spread of fire by up to 4 hours.
In contrast, PIR sandwich panels are combustible and their light density will not be able to stop the spread of fire.
However, with proper installation and sufficient protection with enough surface material, then PIR will not fuel nor reduce the spread of fire in a building.
The arrangement of Rockwool fibers gives it an advantage over PIR on sound insulation.
Rockwool will absorb more sound compared to PIR at the same thickness and therefore is a better choice where insulating against noise is the primary concern.
You should consider the following:
Figure 9 Glasswool sandwich panel
As with the other insulating materials, the main difference comes in the raw materials used in the construction of panels.
Whereas the Rockwool comprise of molten stones which solidify to form an insulating material, glass wool comprises glass fibers that are arranged into wool-like texture and bound together using a binder.
In the process, the glass fibers trap numerous tiny air pockets which contributes to good thermal insulation properties.
Some of the main performance specifications are:
i. Thermal Insulation
The glass wool will give you better thermal insulation compared to a Rockwool sandwich panel.
Besides, the glass wool can achieve a 10% higher thermal efficiency compared to Rockwool.
You can, therefore, use glass wool which is 10% thinner and lighter to achieve the same thermal insulation provided by a thicker and heavier Rockwool sandwich material.
ii. Acoustic Performance
The differences can be small but rock wool will achieve higher noise insulation in most cases compared to glass wool.
iii. Compressive Strength
The parameter is vital where a high weight loading is subjected to the construction.
Generally, The Rock wool will give you almost double the compressive strength compared to glass wool and hence is more suitable in scenarios like the construction of a flat roof.
iv. Fire Resistance
Rockwool offers the best fire resistance compared to glass wool sandwich panels.
The high-density characteristic of Rockwool is most suited for stopping the spread of fire.
On the contrary, the glass wool has a low-density which will not stop flame penetration between the fibers.
v. Working Temperature
Insulating materials have a defined maximum service temperature.
It indicates the maximum and continuous temperature under which the material can continuously function without losing its thermal insulation properties.
The Rock mineral wool can withstand a maximum service temperature of up to 850°C while glass wool will achieve a maximum of 230°C without any physical modification.
vi. Water Resistance
Both glass wool and Rockwool will be affected when water fills the air spaces in the insulating material thus reducing their thermal insulation capacity.
However, the rate of water ingression is dependent on the density of the material, and the lighter the material, the faster the water penetration.
Hence, glass wool will fill faster compared to Rock wool.
Yes, Rockwool Sandwich Panels are used for building walls and roofs.
R-value is a value that indicates the effectiveness of thermal resistance of an insulating material against the heat or thermal conductivity.
The R-value of Rockwool varies to the composition of materials and techniques used for manufacturing. The value can vary from 2.5 to 3.7 ft2·°F·h/BTU.
You should note that the higher the R-value, the better the performance of the insulator.
As you can see there are quite a number of aspects to consider when buying Rockwool sandwich panels.
I hope, this guide answered all questions you had about this panel.
If you have any additional question, feel free to contact Sunnyda team.
As a general rule, Sandwich Panels are composed of two steel sheets and an insulating core with different thicknesses depending on each situation and consumer. Below, you can find the most commonly used materials and the most suitable thickness for each project.
In recent years, the Sandwich Panel has revolutionized the construction industry thanks to its unique features: great thermal and acoustic insulation, its low weight, and its self-supporting capacity for large spans. All this, without forgetting the easy installation and low cost , means that many professionals and end consumers use this kind of material.
The most efficient and common materials on the market that define the composition of sandwich panels are the following:
The rigid foams most frequently used in the production of sandwich panels are polyurethane/polyisocyanurate (PUR/PIR). These materials have a closed-cell composition, their structure is more homogeneous, with lower thermal conductivity and less capacity to absorb water, vapor, or humidity, unlike open-cell structures. In addition, these materials have a very interesting characteristic: they do not change their shape once they have been forged.
On the one hand, polyurethane is a thermosetting polymer, which means it cannot be reconfigured once heated. At Panel Sandwich Group, we use PUR foam in various types of panels due to the great insulating properties it provides. This thermal and acoustic insulating capacity is possible thanks to a density of 40 kg/m³ above the market average, which gives it a low coefficient of thermal conductivity. A relevant fact for the public that is overlooked is the lower density of this foam, the lower the stiffness, and the poorer the insulation.
On the other hand, polyisocyanurate, also known as PIR, is a variant of polyurethane but with greater fire resistance (capable of withstanding temperatures of up to 350ºC before decomposing, while PUR foams begin to fragment at 250ºC). Another characteristic of PIR foams is their ability to extinguish the fire without contributing to its propagation. Logically, its cost is slightly higher than PUR since it has a different composition with more expensive raw materials.
Both foams are used in many of the multi-panels available from Panel Sandwich Group, such as the Tile Roof, the Roofing Panel (Cover-joints Sandwich Panel, Sandwich Panel Three and Five Frets),and the Insulated Wall Panel (Insulated Internal Wall Panel, Outside Insulated Wall Panel Panel and Architectural Insulated Panel). Although both types of foam are used, polyurethane foam or PUR is the most demanded because it's low priced, while PIR is used when there are large manufacturing volumes. In the case of the Agricultural Metal Roofing and the False Ceiling Panel with Polyester or Pural Aluminum, both multi-panels are composed of a polyester sheet which is very useful to avoid corrosion from the animals' wind, but it is not fire resistant. Therefore, to low the cost, it is manufactured exclusively with PUR foam.
The core of sandwich panels can also be composed of slabs of inorganic fibers that provide high fire resistance than rigid foams. Rock wool is a natural fiber used for acoustic insulation and fire protection. Its composition of natural fibers keeps the air dry inside and is a natural obstacle to heat transfer, slowing down the temperature changes from the outside to the inside, resulting in higher thermal insulation. In addition, rock wool has properties that stop sound waves, act as a barrier to sound, and provide acoustic insulation. In addition, its high density (from 100kg/m3 to 175kg/m3) makes it practically incombustible.
Thanks to the aforementioned characteristics, rock wool is the ideal solution for working in areas with fire or combustion risk or for spaces where soundproofing is required, reducing noise by 35 decibels when using its greater thickness. It is usually applied in Insulated Wall Panels or Insualted Ceiling Panels.
It is a rigid plastic that is used in an infinity of products since its cost is very low. Besides this, it is a material that stands out for its high thermal insulation and strong resistance against filtrations and humidity.
In Panel Sandwich Group, we use this material in the SIP Panel since the adhesion of the PUR foam is weak to the wood and the polystyrene acts as a strong and stable adhesive.
In Panel Sandwich Group, we have extensive experience advising our customers. Over time we have detected that many of our customers repeatedly asked us the same question: What is the most suitable thickness for my project? If you have this concern, below you can find some basic notions on this topic to better orient yourself according to your project.
In the specific case of wanting to renovate or build a home, the most important thing is that the panel contains a high level of thermal insulation which in turn generates energy savings derived from it. For this type of case, the most advisable is to use a high thickness in the ceilings and a high thickness for the walls.
What type of thickness is most suitable for my home? It depends on the panel you want to use. If you want to modify the roof of your home, the Roof Tile Sandwich Panel is the most used for this type of project due to its aesthetic finish and high thermal insulation. The most common thickness is 55 mm with a white or imitation wood interior finish. If the Tile Panel does not adapt to the characteristics of your project, the Cover-joints Sandwich Panel is also in great demand and may fit perfectly, with 60 mm being the most common thickness in homes.
In the case of home walls, there are several options. If you would like to save money on your project, the best option is to install a Wall Panel with exposed screws, whose most commonly used thickness is 50 mm. If you are looking for an aesthetic look, the Architectural Insulated Panel with 50 mm or 60 mm thickness is sufficient.
Another panel frequently used in this type of construction is the Wood Sandwich Panel. It is one of the most demanded and can be used for roofs and walls, being the most common at 40 and 80 mm.
If you are thinking of building a hut, shed, or warehouse in your garden or land, you may ask yourself, is it necessary to have a high thickness as in the previous case? Well, not really. This type of construction is not going to have a residential use and, therefore, does not need so much insulation, it is better to reduce costs by using a lower thickness.
For walls, the most interesting panels are the Insulated Internal Wall Panel. If you are looking for something low-cost and less aesthetic, the most suitable thickness for this type of project would be 30 mm. If, on the other hand, you are looking for something more aesthetic by hiding the screw, a Outside Insulated Wall Panel with a thickness of 35 mm would be the ideal choice.
If by any chance you are looking to build a car garage, as in the previous case, insulation is not so important; it is better to reduce operation costs by using low thicknesses.
For these constructions, it is common to combine Wall Panels with visible or hidden fasteners for the walls with Cover-joints Sandwich Panel and Sandwich Panel Three Frets or Five Frets. There is also the possibility of using the same wall panel for the whole construction if it does not have to support heavy weights.
One of the most recurrent works of our clients is the rustic porches of their homes. Depending on the panel chosen, the results will be very different. Residential porches only need roof panels. For this reason, the most commonly used are the sandwich panels and Tile Roofs, which can be imitation wood on the inside to give a superior aesthetically to the porch, an important facet in this type of construction. As in the previous cases, the porches do not need high thermal insulation, so a thickness of 50 mm in Tile and 30 mm in Cover-joints is enough.
If you are a businessman and looking to renovate an industrial building, this publication may solve your doubt: What is the most suitable thickness for my building? Well, it depends on the industry in which you operate.
If you operate in the agri-food sector and use your warehouses to store food products such as fruits, vegetables, meats, and others, the Cold Storage Panels for both ceiling and wall are ideal to fulfill this function. If we talk about thickness, this decision depends on many factors, from budget to refrigeration needs.
In case you need to maintain temperatures below zero, the ideal is the maximum thickness which is about 200 mm while if you do not need to maintain such extreme temperatures, 180 mm is enough.
Another situation that can occur is that you need a panel for a building without high requirements in terms of temperature and looking for protection, insulation, and humidity-free space to perform your operations. In this case, the most common is to install a roof panel and a wall panel in a thickness that is effective, easy, and quick to install at a reasonable price.
For the roof, the Cover-joints Sandwich Panel would be the most interesting. The most common thicknesses are 30 and 60 mm, although higher thicknesses can be chosen if greater strength is required. These panels can be combined with Insulated Wall Panels with thicknesses between 50 and 100 mm. Whatever the thickness of the panel, it will maintain excellent insulation that can increase as the thickness increases, so your choice will depend on the budget and the requirements of each project.
On the contrary, your project may be more related to a quality industrial building with thermal and acoustic insulation designed to work inside comfortably throughout the year. For these cases, it is advisable to use a three-frets sandwich panel with a thickness of 30 mm, although it can be greater depending on the geographical area in the United States in which you are located. It must be taken into account that these panels are used to avoid high temperatures in summer and too low in winter. These panels have enough thermal insulation to avoid humidity, condensation, and extreme temperatures throughout the year, always at the best price.
Regarding the walls, the most demanded is the 30 mm Insulated Internal Wall Panel as it insulates thermally from extreme temperatures, has enough body to withstand large spans between support points, and, being usually in white, they are clean and durable. As an alternative option, the Outside Insulated Wall Panel is also frequently requested. These panels are 35 mm thick, slightly thicker than the previous one. Both have similar characteristics with the exception that the latter is more aesthetically pleasing as the hardware is hidden.
Previously we have shown insulation and protection options provided by Cold Room Panels in buildings that require it. We have also explained the kind of panels that are needed to achieve adequate insulation for an industrial building that does not require these conditions. All these options are good, but perhaps you are only looking for a low-cost option for your development. Therefore, let's talk about galvanized sheets that adapt to more limited budgets and with lower thermal insulation requirements.
The Profiled Sheets without an insulating core have the following characteristic: this kind of sheets its incredible resistance to corrosion, which makes them ideal for farms and in covering warehouses and buildings. The thicknesses of these sheets range from 32 to 50 mm, with 32 mm being the most economical and in demand. Thanks to its easy installation, the different colors in which it is available, and its watertight characteristics that prevent leaks and humidity, it has become one of the most demanded options at a lower cost than the sandwich panel.
As mentioned before, these sheets are ideal for farms since they resist corrosion from harmful gases from cattle and pigs. This kind of panel is designed for chemical industries, farms, and corrosive environments and is called Agricultural Metal Roofing. What differentiates them from other sheets is that their bottom sheet is fiberglass-reinforced polyester. This part of the sheet makes the Agropanel resistant to corrosion caused by the gases inside.
The thicknesses will vary depending on the animal housed inside, being the most recommended 30 mm if the farm is for cattle or pigs, 40 mm for chickens, or 50 mm for open pools for fish farming.
The overall thought is to think if these panels will be used outside or inside the development. It is possible to install either sandwich panels with a reinforced polyester interior in case it is in contact with the exterior or a False Ceiling in case it is installed as a lining for an existing ceiling.
False Ceilings are used when you need to reinforce the interior without incurring high expenses. The False Roof of Polyester is characterized by the fact that both sides of the panel are made of polyester, giving it maximum protection and durability. In terms of insulation thickness, the usual thickness is 30 mm, since this type of panel is designed to cover pre-existing ceilings and walls, together with the air chamber formed when it is installed, is more than enough to easily obtain the temperature we want. But in cases such as chicken farming or where there is no pre-existing insulation, the ideal is to go up to 50 mm thick and compensate for the lack of insulation with the false ceiling.
