Insulating Walls with Pavatex wood fibre insulation

External Wall Insulation (EWI) is an excellent way of insulating the external walls of a new or existing property because the complete building envelope is wrapped in insulation, and so cold bridges through junctions are avoided e.g. where internal walls meet the external wall. Pavatex wood fibre insulation boards are installed directly onto the outside of external walls, irrespective of whether the walls are constructed of solid or cavity masonry or timber frame. The walls must be smooth and level before insulating so they may need to be first rendered with a breathable render basecoat e.g. lime or clay
