External Wall Insulation & Silicone Rendering

How we do what we do

External wall insulation (EWI) is a type of insulation that is applied to the exterior surface of a building’s walls to improve thermal performance. It involves fitting insulation boards or panels to the outside of the building’s walls, which are then covered with a protective render. Silicone rendering is a type of render that is used as a protective layer for EWI systems. It is a flexible, weather-resistant coating that is applied to the insulation boards to protect them from the elements. Silicone rendering provides a durable and long-lasting finish that is easy to maintain and can be tinted to a range of colours. Together, EWI and Silicone Rendering can significantly improve the energy efficiency of a building, reduce energy bills, and protect the building from weather damage. They are commonly used in retrofitting projects to improve the thermal performance of older buildings.
