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 un-changed over time.

In addition, PIR foam is difficult to ignite, suitable for buildings with structural fire resistance requirements. PIR polyurethane foam 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 0.023 W / mK
  • 95% closed cell structure
  • Fire response, difficult to ignite, class B s1 d0, (PIR)

 

Metal Sheet Options

Pre-painted and galvanized 0.50mm thick steel sheets are usually used. Optional there are available metal sheets from different materials and thicknesses.

  • Steel pre-painted 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 metal face with 5-rib trapezoidal profile 42/250 or 3-rib trapezoidal profile 42/500 . The external face can be Light profiled (Box 65-55) or Embossed (under certain conditions).

 

Internal Face Profiles

Internal face profiles with or without light formation. The internal face can be Flat or Light profiled (Box 70-75). 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).

Coatings And Colors Options

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).

Essential Properties

Nominal Thickness Weight per unit length * Thermal transmittance **
[mm] [kg/m*] [W/m2.K]

* Weight per unit length was calculated taking into account the core density of 40kg / m3, and the nominal thickness of steel faces 0.50mm / 0.50mm.

** Thermal transmittance coefficient was calculated taking into account the core density 40kg / m3, thermal conductivity coefficient of 0.023 W / mK and the nominal thickness of steel faces.50mm / 0.50mm.

The PIR polyurethane covering panels are classified in notified laboratories, according to EN 13501-1 and EN 13501-2, in terms of reaction and resistance to fire. Please request the classification report.

Connection/Support Options

The polyurethane roof panels are fixed to the bearing structure by the standard method of visible anchoring.

They are designed as covering panels for roofs with a slope of not less than 10%. On sloping roofs with a slope of more than 10% it is recommended to install more than one panel in the slope direction. In this case the panels must have an overlap configuration. The transverse overlap can be right or left depending on the project specifications. The length of the overlap varies from 50mm to 300mm. The panels are usually supplied without overlap and cross-cut (removing part of the internal sheet and core) is done at the project site.

The characteristic design of the joints of the panels in combination with the use of sealants minimizes panel-to-panel spaces and thus achieves:

  • Reduce the thermal bridges to a minimum
  • Restriction of air and moisture penetration
  • Minimize installation time
  • Limited use of extra accessories
