External Wall Insulation

Render is a sand/cement/lime mix that can be applied to a range of sound masonry substrates to provide excellent long-lasting finishes to the outside of a building. It is primarily used to cover up, waterproof and improve the façade of an aging exterior. It is also a fundamental component in EWI and insulated render systems.

Ainsworth are able to supply render products in a wide variety of colours, textures and finishes. We have access to 48 standard colours, with the facility to supply bespoke colours on request.   

External wall insulation (EWI) is a method of improving the energy efficiency of solid wall buildings which cannot be efficiently insulated through internal wall (cavity) insulation. EWI involves fixing a layer of insulation material to an external wall and then covering it with a special type of render or cladding. Primarily, EWI is used in restoration projects as it improves the energy efficacy and aesthetic appearance of a property.       

Ainsworth are able to supply all the required EWI materials and components ensuring that a high-quality system is achieved, backed by manufacturer guarantee.
