Overview
External wall insulation (EWI) employs a layer of insulation fixed to the exterior substrate of a building., which is then covered with decorative and protective rendered finish. Enveloping the building in this way reduces energy bills, rejuvenates tires exteriors and prolongs the life of the structure.
EWI is effective when applied to a solid wall construction or to walls without an insulated cavity.
Thermal performance of EWI is dependant on the type of insulation used. To Cater for all budgets and requirements, EWI systems can be used with Expanded Polystyrene, Mineral Wool, PIR or Phenolic boards.
Mineral renders are extremely robust and come in a number of finished colours and textures. Synthetic finishes offer an even greater choice of vibrant colours to bring a tired exterior back to life.
