The UK has always been fond of building houses with impressive durability, and visually appealing designs. As energy costs increase, and building regulations get stricter, UK homeowners and developers are also emphasizing sustainability. Installing an External Wall Insulation has been one of the most effective methods.
EWI(external wall insulation) comes with many benefits for homes. Housing associations, landlords, construction managers, and commercial rendering contractors in UK must know how they can improve the performance and appearance of homes and buildings.
This blog is about the benefits of these solutions; challenges they help deal with and the best practices for applying them to homes and buildings.
What is EWI (External Wall Insulation) ?
Let’s get our basics set first.
EWI
The process involves fixing insulation boards—typically mineral wool, EPS (expanded polystyrene), or phenolic foam—onto the external walls of a building.
- The insulation boards minimise the heat loss in buildings.
- That helps cut down on energy bills for residents.
- The house gets better thermal comfort in both winter and summer.
- EWI also protects against damp, condensation, and mould growth.
- It shields external walls from the elements and makes them more durable.
Most experts recommend mineral wool systems for homes and buildings. Their non-combustible properties make them a great choice.
Rendering for Homes and buildings
It is the process of applying a protective and decorative layer of material on the exteriors of a building.
