Thermal insulation boards for the insulation of buildings and structures made of high index rigid polyurethane foam PUR or PIR are used to achieve energy upgrading and saving of buildings. They reduce building losses and help reduce CO2 emissions to the environment.

They apply as insulating material to all types of buildings, to masonry (interior and exterior) and ceilings (interior and exterior). One of their main applications is to insulate the floors of the cold rooms.

 

They are distinguished for:
  • Exceptional reaction to fire, class B s1 d0 (PIR)
  • Excellent thermal insulation capacity, U value
  • High compressive strength over other insulators
  • Free from dangerous substances, CFC & HCFC free

 

Produced with:
  • Cover width 1150mm and nominal thickness 30mm, 50mm, 80mm, 100mm
  • in custom lengths from 2m to 8m, depending on the project

Characteristic Materials

 

PUR / PIR polyurethane insulation core

The PUR polyurethane foam core of high density 40 kg/m3 has excel-lent 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)

 

Side sheets

Stoneglass white paper surfaces, suitable for PU plates for external insulation application. Suitable for accepting most types of coatings. The rough surface enhances adhesion. It is waterproof with additives against mold and algae. It is classified in class E according to EN 11925.

Cart 90 black paper surfaces, suitable for PU plates, for insulation of metal surfaces. Bitumen for extra waterproofing. Waterproof with anti-mold and algae additives. With slides for anti-skid protection and enhanced traction. Very lightweight and resistant to mechanical stress and low temperatures.

It is possible to produce slabs with aluminum foil or even flat polyester sheets up to 1mm thick, where the environment is extremely corrosive.

Nominal Thickness Weight per unit length * Thermal transmittance ** Thermal resistance **
[mm] [kg/m*] [W/m2.K] [m2.K / W]
30 1,40 0,78 1,40
50 2,30 0,44 2,30
80 3,70 0,29 3,50
100 4,60 0,23 4,35

 

* Weight per unit length was calculated taking into account the core density of 40kg/m3

** Thermal transmittance coefficient was calculated taking into account the core density of 40kg / m3, thermal conductivity coefficient of 0.023 W / mK.

The PIR polyurethane thermal insulating boards are classified as B s1 d0, according to EN 13501-1 and EN 13501-2, in terms of reaction and resistance to fire.

Connection / Support Options

Thermal insulation boards are attached to the structural elements either with adhesive or with anchors (plastic or metal). In any case, in the joint between the boards, it is recommended to use a sealant (usually low swelling polyurethane foam) to seal the structure.

 

When insulating both vertical and horizontal building blocks, the polyurethane thermal insulating boards must be fully supported. The boards, unlike the panels, are not designed to carry loads.
