External Wall Insulation
Designed for solid brick properties. Wrap your home exterior in a high-grade thermal barrier and render coat.
Service Overview
Solid-brick properties built before 1920 do not have cavities and lose heat twice as fast as modern homes. External Wall Insulation (EWI) wraps the exterior structure of your home in a continuous blanket of insulation. We fix high-density expanded polystyrene or mineral wool slabs directly to the external walls, apply a reinforced fiberglass mesh layer, and finish with a decorative, weather-resistant silicone render. EWI not only dramatically increases heat retention but also completely updates the exterior aesthetic of older homes.
Key Benefits & Efficiency Gains
Frequently Asked Questions
Does external wall insulation require planning permission?
If the material changes the visual appearance of the property or if you live in a conservation area, you will need to notify the local council. We assist with all approvals.
Is external insulation weather-dependent?
Yes. The rendering and plastering phases require dry weather and temperatures above 5°C for proper curing.
