What is EWI Insulation?

External wall insulation

External wall insulation, which is also referred to as EWI and external solid wall insulation, is a type of insulation that is affixed to the exterior of a building's walls. Two layers of materials are used to create it - one for insulation and an outer layer made of mineral or synthetic render that serves as protection against weather and provides an attractive finish.

Is EWI worth it?

If your home is not properly insulated, investing in EWI can help reduce heat loss and lower energy bills, making it a valuable long-term investment.

Does EWI stop damp?

In conclusion, External Wall Insulation (EWI) provides an effective barrier against moisture, improves airtightness, and when combined with ventilation, offers a complete solution for any condensation and damp issues.

How long does it take to install external wall insulation?

An accredited installer fits an external wall insulation system to a property in layers, which include insulation boarding,  render, and a decorative waterproof topcoat (Render). The estimated time for installation is around 7 to 10 days for an average semi-detached house.

How thick should my external wall insulation be?

To achieve a thermal conductivity of 0.3W/m2K or better, external wall insulation needs to be of the right thickness. Generally, the insulation should be around 60mm thick, but it can go up to 100mm depending on the material of your existing wall.
