Evatherm L

PIR Insulation For Warm Flat Roofs

Evatherm L is a high performance rigid polyisocyanurate (PIR) foam board with rebated ends for use in warm roofs under a Liquid Applied Waterproofing system, such as the ICB Mariseal PU system and ICB PMMA FLEET System.

The board is tongue and grooved, but taping the joints is still essential and may provide a better finish with less ghosting of the joints being visible. For tapered roofing, we recommend anormal tapered system using Evatherm A is installed with a finishing 50m layer of Evatherm L.
