EpsiLine Insulation Boards

Introduction

epsiline-pir-plasterboard-laminateThe primary component of Wetherby’s EpsiLine Internal Wall Insulation System is the high performance thermal insulation board, which is supplied pre-bonded to a tapered edge, standard plasterboard.

EpsiLine insulation boards are manufactured from rigid polyisocyanurate (PIR) using a blowing agent that has zero ozone depletion potential (zero ODP) and low global warming potential (GWP).

The EpsiLine IWI System can easily be used to upgrade properties to current building regulations and is particularly suited to domestic refurbishment. It provides a reliable long term energy saving benefit for buildings and is ideal for properties where no cavity exists (solid wall). A highly effective internal solution, EpsiLineIWI is perfect for projects that have restricted external planning constraints.
