Eco-Versal - For Solid & Timber Frame Walls

Eco-Versal is a foil faced universal solution for insulating walls, floors, pitched roofs, dormer cheeks and ceilings. It is ideal for insulating timber frame walls and can also be used to insulate solid walls internally.


Suitable for use in between and over the studs of timber frame walls in new build or for upgrading the thermal performance of existing walls.  Eco-Versal can also be used internally on solid or cavity walls to upgrade their thermal performance.  The excellent thermal performance of EcoTherm's PIR insulation will keep the wall thickness to a minimum and provide a cost effective means of reducing CO2 emissions and compliance with Building Regulations/Standards.


EcoTherm Eco-Versal comprises a fibre free rigid polyisocyanurate (PIR) insulation core faced with an aluminium foil composite on both sides.
