Ystalyfera, Swansea Valley, South Wales

Installation of EWi PRO eaves and verge system on an insulation scheme of 200+ properties


Project Brief…


NPT Homes, based in Neath Port Talbot, South Wales have recently used the EWi PRO eaves and verge system on a number of their properties in Ystalyfera, Swansea. These properties were classed as hard to treat, in the very exposed location of the Swansea valley and the client had concerns over the longevity and reliability, especially at the key property junctions prior to the installation of external wall insulation.

The properties were of solid wall construction and NPT Homes had specified a 100mm thick external wall insulation system, but they had no overhang at the eaves or verge areas. This makes it difficult to fully weatherproof and insulate these areas using the current industry standard details, without going to the high expense of extending the roofs at the front, rear and gable ends and replacing all the rain water goods.

In the past NPT Homes would have used the traditional aluminium trim system that is highly reliant upon silicone sealant at a number of these key junctions. After being introduced to EWi PRO, these issues and risks were further recognised but by working together through each individual concern these risks were reduced and eliminated by using the EWi PRO eaves and verge system.

"NPT Homes has been pleased to be able to use the EWi PRO system on a number of our properties. It has provided a far more robust and secure method of protecting the EWI system at these points and it will contribute significantly to the longevity of the system." ~ Mr Christopher Price - NPT Homes Ltd - Planned & Contract Works Manager
