Characteristic Materials
PUR / PIR polyurethane insulation core
The PUR polyurethane foam core of high density 40 kg/m3 has excellent resistance to heat transfer. It is proven that is the best thermal insulation material in the construction sector.
It does not contain harmful substances, it is odorless and safe for health and the environment. It does not contain CFC & HCFC, ozone-depleting substances. It is recyclable and can be used for production of secondary products. Its closed cell structure is chemically neutral and this makes it resistant to moisture and mold. It is durable and its properties remain unchanged over time.
In addition, PIR foam is difficult to ignite, suitable for buildings with structural fire resistance requirements. PIR polyurethane foam panel is classified as B-s1-d0 according to standard EN 13501-1, meaning it does not transmit fire, it is difficult to ignite, has no/hardly any smoke production and does not produce flaming or non-flaming particles.
Essential characteristics:
- Density 40 ± 2 kg/m3 (high index)
- Thermal conductivity, λ 0,020 W/mK
- 95% closed cell structure
- Fire response, difficult to ignite, class B s1 d0
Metal Sheet Options
Prepainted and galvanized 0.50mm thick steel sheets are usually used. Optional there are available metal sheets from different materials and thicknesses.
- Steel prepainted and galvanized or with aluminum alloy protective coating, according to EN 10346 & EN 10143, from 0.35 mm to 1.0 mm, with Polyester, Plastisol, PVDF color coatings.
- Aluminum alloy of series 1xxx, 2xxx, 3xxx, plain or pre painted with Aluzinc protective coating, according to EN 508-2, with a nominal thickness of 0.35 mm to 1.0 mm.
- Stainless steel, AISI 304 2B or AISI 316 L, from 0.35 mm to 1.0 mm, without color coating, mat or gloss.
External Face Profiles
External face profiles without light formation flat or with light formation such as Box 100 (50-50), Mini Box 51 (25,5-25,5), Microrib and Embossed.
Internal Face Profiles
Internal face profiles without light formation flat or with light formation such as Box 100 (50-50), Mini Box 51 (25,5-25,5) and Embossed.
Upon request, there is an option to produce panels where the internal metal sheet can be replaced by a flat polyester sheet of thickness up to 1mm, wherever the environment is extremely corrosive.
Please ask us about the available coatings (Polyester, Plastisol, PVDF, Food Safe, Non-Toxic and Anti-mold) and colors (RAL1014 to RAL 9010).
Classic Polyester Paint
Polyester paints are the most common and most economical coatings. They are suitable for both external and internal surfaces. With a nominal coating thickness of> 20µm they have a very good resistance to external environmental conditions.
Durable Plastisol Paint
Plastisol coating is very durable to external environmental conditions. It belongs to the category of “self-healing” coatings on mechanical damage. With a nominal coating thickness of 200µm it is suitable for outdoor applications where the durable requirements are high.
High req PVDF paint
PVDF paint is suitable for buildings of architectural applications where the texture and color retention are important. The nominal thickness of the coating is 50µm and is classified in category s1, in terms of its reaction to fire.
Coating Color Options
An extremely large number of color coating options are available. Please refer to our sales department for the available colors (RAL1014 to RAL 9010).

* Weight per unit length was calculated taking into account the core density of 40 kg/m3, and the nominal thickness of steel faces 0.50mm / 0.50mm.
** Thermal transmittance coefficient was calculated taking into account the core density 40 kg/m3, thermal conductivity coefficient of 0.023 W/mK and the nominal thickness of steel faces 0.50mm / 0.50mm.
The PIR wall covering panels are classified in notified laboratories, as B s1 d0, according to EN 13501-1, in terms of reaction to fire. Please request the classification report.
Polyurethane wall covering panels are available with two types of joint, visible fixing and hidden fixing. In both visible and hidden fixing the panels can be mounted either vertically or horizontally.
The characteristic design of the joints of the panels in combination with the use of sealants minimizes panel-to-panel space and thus achieves:
- Reduce the thermal bridges to a minimum
- Restriction of air and moisture penetration
- Minimize installation time
- Limited use of extra accessories
Visible Fixing
Mineral wool wall covering panels are fastened to the bearing structure by the standard method of visible anchoring. This method adds strength to the construction and an industrial look to the building.
Hidden Fixing
There are also available hidden fixing panels which are fastened to the bearing structure by the method of hidden anchoring. The panel has such a configuration in its profile so that the support elements are not visible and therefore offer an excellent aesthetic effect without depriving their characteristic properties.
