PIR SL

A rigid polyisocyanurate (PIR) foam panel coated on both sides with a Kraft paper multilayer complex and a metal sheet. 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 properties of the PIR SL panel ensure a high thermal comfort once installed.

The PIR SL panel also has remarkable mechanical properties, facilitating its application as a thermal insulator for different types of radiant floors, electric or hydronic. The printing of a grid system on one of the sides facilitates the design and layout of the circuits on the panel.
