External Wall Insulation (EWI)
External Wall Insulation also referred to Solid Wall Insulation is a thermally insulated, protective and decorative exterior cladding used to insulate and protect the exterior wall. EWI is often used to improve the safety of buildings through fire-proofing as insulated render systems containing mineral wool are resistant to fire.
However, general benefits include; improved aesthetics through remodelling by a variety of finishes, retaining heat within the property therefore lowering fuel bills, improved acoustic insulation, reducing future maintenance of the exterior on the property and render finishes are breathable and will in turn reduce the risk of dampness.
EWI - Existing Buildings
PJ Mear have wide experience in the use of insulated render systems across traditional and non-traditional substrates and structures. These include cavity wall, solid wall, dense and no-fines concrete, brick, block, stone, metal, tile or timber clad structures.
For use on multi-storey buildings, external wall insulation systems provide strong resistance to fire through the use of A2 and A1 rated fire classification that the EWI manufacturers below supply.
EWI - New Build Projects
EWI is perfect for new build applications that have utilised SFS structures. The systems can be applied directly to cement particle boards or sheathing boards such as Y-Wall, Knauf Aqua Panel, Kooltherm, Versapanel. These systems are designed to be lightweight, quick to apply, durable and versatile with a wide range of colours/finishes to be chosen.
PJ Mear offer a wide range of finishes and colours ranging from Spar Dash, Silicone & Acrylic Render, Smooth Render, Ashlar Render, Acrylic & Brick Slip Finish & Brick Render.
