EWI Pro

General information

One groundbreaking product we have developed is the EWI Pro Gutter®, a complete modular system that is designed to provide a completely weather tight finish for EWI installations. It can be used for most domestic situations where lack of roof overhang presents difficulties, no matter whether the property is terrace, semi or detached or when it was built.

The application of external wall insulation (EWI) to existing buildings presents a huge energy saving opportunity. It also presents detailing challenges for the installer, particularly at the eaves and verge in instances where there is insufficient overhang to cover the depth of the new wall insulation.

Current industry practise relies on the use of basic trims to deal with the interfaces between wall and roof. These trims are normally fitted below the existing gutter and facia boards. Corners junctions between eaves and verge are normally made up on site with varying degrees of success and critical junctions often rely on mastic sealants as the primary line of defence against water ingress. The resulting arrangements are often of questionable quality from visual, weathering and cold bridging viewpoints. The weathering risks and potential for failure are not hard to foresee even on projects where the installers have been as careful as possible.
