Minimise The Energy Needed To Heat Your Property 

An external wall insulation system (or EWIS) is a protective, thermally insulated, decorative exterior cladding procedure that employs mineral wool, expanded polystyrene, phenolic foam, or polyurethane foam, which is then topped with a reinforced cement-based, synthetic mineral finish, and plaster. 
External wall insulation is an excellent and proven way to minimise the amount of energy required to heat the property. Installing it is a component of an eco-friendly or carbon-neutral house design. 
Different layers of insulation consistent with the text description
External wall insulation solutions typically consist of two components: an insulating layer, which contributes to the required thermal performance, and a protected weatherproof finish, usually a render, although decorative boards, tiles, and brick slips, can also be used. In some cases, insulating render might be advantageous. The kinds and sizes used will be determined by the substrate and design exposure specifications. 
Dry finishes are often attached to the substrate with timber battens that are individually fastened to the substrate. Our skilled team offers EWI systems that may be completed with either a Monocouche Render or a Silicone Render System

What Are the Benefits of Exterior Wall Insulation? 

✔ EWI provides a greater sense of comfort and cosiness. 
✔ It enables walls to add heat mass. 
✔ It causes little disruption to the home while it is being fitted. 
✔ It lowers heat loss and energy costs. 
✔ It extends the life of the wall. 
✔ It enhances not just weatherproofing but also acoustic resistance. 
✔ This type of insulation has no effect on the internal floor space. 
✔ It helps to minimise condensation on inside walls. 
We are also experts at finishing the external wall insulation in anticrack system silicon coloured render, light Monocouche or brick slips.
