EWI system is a thermally insulated, protective, decorative exterior cladding involving the use of polystyrene, mineral wool, polyurethane or phenolic foam being secured to the exterior walls by mechanical fixings and adhesive, followed by a reinforced cement based, mineral, synthetic or brick slip render finish. ProRend UK are the trusted company when it comes to installing External Wall Insulation in Surrey.
EWI provides a thermal jacket around the building. Insulation boards come in different thicknesses depending on what u-value is to be achieved. Good insulation installed to the exterior envelope of buildings reduces heat loss to the outside, thus ensuring considerable cost savings due to reduction in heating and cooling bills. Also it adds extra protection to the building and very low risk of condensation. EWI can be installed to most substrates and comes in many colours/finishes for the client to choose from. In recent years, ProRend UK has successfully equipped several homes with External Wall Insulation in Kent.
We can install insulation 12 months a year, but for those who are planning on keeping their home warmer throughout the coming winter, we are also installing External Wall Insulation in Sussex in the coming months.
