Polyisocyanurate panels are used as a component of thermal insulation systems. They provide efficient thermal insulation as compared to other construction materials such as mineral wool or foamed polystyrene. They allow for cost-effective, long-lasting, and safe use of a house or an apartment.
Polyisocyanurate panels are used to insulate:
- exterior walls;
- terraces and balconies;
- flat roofs, and pitched roofs.
PIR term-AL construction
The double-sided panel lining is made of KRAFT paper covered with aluminium (AL). The core of the panel is made of rigid polyisocyanurate foam (PIR) with very good insulating and fire-resistance properties Edges are milled for ease of installation and improvement in thermal insulation.
Milling can be performed as follows:
|Straight edges||Overlap edges||Tounge and Groove|
|Apparent density of core||kg/m3||30 (+6/-2)|
|Declared heat conductivity coefficient λD||W/m*K||0.022|
|Thermal resistance RD||m2*K/W||0.90||1.80||2.25||2.70||3.60||4.50||5.45||6.80||8.15||9.05||10.00||11.35|
