Should you consider external wall insulation?
External wall insulation can transform the thermal performance of a suitable solid-wall property and renew the exterior at the same time, but it is a major building-envelope project where detailing and moisture management matter as much as insulation thickness.
- Warmer internal wall surfaces and improved comfort.
- Reduced heat loss through solid walls.
- Potentially less surface condensation on cold walls when moisture and ventilation are properly managed.
- A renewed external appearance and weather layer.
