PIR-ALK

A rigid polyisocyanurate (PIR) foam panel coated on both sides with an aluminium multilayer complex. The material's main characteristics are: a high thermal resistance which enables the use of thinner insulating panels, and rigidity and lightness which facilitate handling and installation. The high insulating property of the panel PIR ALK combined with the reflective capacity of the outer aluminum layer ensures a high thermal comfort, once installed.

The panel PIR ALK also has remarkable mechanical properties and excellent dimensional stability.
