Project requirements

Although the project did not aim to achieve EnerPHit certification, Ian wanted to see how far he could go with improving his home’s thermal performance and comfort levels, given the constraints of the site and budgetary considerations. The retrofit strategies included extensive insulation and airtightness improvements as well as replacement of the existing windows and doors with Green Building Store’s triple glazed PERFORMANCE timber range.



Solution

Triple glazed timber inward opening tilt and turn window (78mm profile). "We looked at a range of windows and Green Building Store’s PERFORMANCE range was by far the most cost-effective of all the quotes we received. They were of a high quality and the U value fitted the bill for the level of retrofit that we were aiming for".



Benefits

Uw value 0.85 W/m2K in a good-looking, cost-effective window system.

Client Feedback

"We have also been very happy with Green Building Store’s after-sales service. There were no quibbles when we needed to replace a failed glazing unit and, while they were replacing it, the team also helped us adjust some of the doors in the house (fitted by another company)".
