EWI - Insulated Render Systems
External wall insulation systems function as a thermal insulator and a layer of protection against the elements. The EWI is then finished with a cement based, mineral or synthetic render to give your build the aesthetic look you want
As well as increasing thermal insulation and providing protection, an EWI - Insulated Render System also provides exceptional sound insulation. The external render is also used to prevent the build-up of moisture in the external walls which reduces the risk of condensation and extends the life of the structure.
External wall insulation systems
- Polystyrene insulation - a dense and lightweight material, inexpensive, with excellent thermal insulation properties and moisture resistant.
- Phenolic insulation - a rigid insulating foam that has very good thermal insulating properties.
- PIR (polyisocyanurate) insulation - a highly efficient and lightweight material with excellent thermal insulation properties.
- Mineral wool and Glass wool - a breathable, vapour resistant, fireproof insulation material
Types of Render Finish
- Acrylic renders
- Mosaic renders
- Mineral renders
- Silicone renders
- Silicate Renders
