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-WS construction
The double-sided panel lining is made of fiberglass. The core of the panel is made of rigid polyisocyanurate foam (PIR) with very good insulating and fire-resistance properties.
Milling can be performed as follows:
