External Wall Insulation Systems





External Wall Insulation (EWI)

EWI is the application of an insulation layer to the outside wall of a building in order to improve the building’s energy efficiency.

By minimising heat loss in cold weather and heat gain in warm weather, EWI creates a much more comfortable living environment and reduces heating costs by up to as much as 40% with less risk of condensation and damp walls.

BlueBuild Insulation are proud to be sole distribution agents for Soltherm in Northern Ireland.


New Buildings

Aesthetic choice and high technical performance make EWI an excellent solution for all types of new build projects including homes, industrial, commercial and public buildings such as offices, shops, hospitals and schools. This can be used to achieve passive house certification.

Social Housing

EWI systems now available means that there is a solution to refurbish even the largest, most ‘hard to treat’ social housing properties which can present a multitude of design issues as a result of non-traditional construction methods

Existing Solid Wall Buildings

Solid walls are found in most houses built before the 1930s so, if a property dates back to Edwardian, Victorian or Georgian times, its walls are likely to be solid. EWI can also be used to further improve the performance of cavity walls, and non-traditional properties.
