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:
- foundations;
- walls;
- exterior walls;
- ceilings;
- 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.
Joint types
Milling can be performed as follows:
| FIT | LAP | TAG |
| Straight edges | Overlap edges | Tounge and Groove |
