Triple glazed timber windows and doors at Sussex low energy retrofit Green Building Store

Sussex low energy retrofit

PERFORMANCE triple glazed timber windows with glazing bars
I researched widely and attended many exhibitions and Green Building Store’s PERFORMANCE triple glazed range was the only range which combined my energy efficiency criteria with the traditional style that the project required.

The project aimed to combine good quality materials and great attention to detail to deliver a good quality refurbishment. Green Building Store’s PERFORMANCE windows provided the quality that I needed.

I’m really pleased with the colours and appearance of the windows which work really well with the traditional hung tile style of the house.

In terms of after-sales support, Green Building Store was also quick to respond when I needed some adjustments after installation. My only regret is that I wish I could have used Green Building Store’s own fitting team to install the windows in the first place.

Green Building Store were very helpful to deal with and very patient when I had to tweak the plans prior to ordering. I have already recommended Green Building Store to two other friends, who have been very happy with their windows as well.

When Jerry Hooper wanted to re-locate in the south-east he was looking for a location that was both rural but also within walking distance of local amenities. He eventually found a 1900s house, which had been extended in the 1960s in the traditional Sussex ‘Hung Tile’ style and greatly in need of repair. Jerry wanted to create an environmentally sound house with a remit including thermal efficiency, minimising water and carbon footprint and increasing the light coming into the house, while also retaining the traditional appearance of the house.

Jerry designed and project-managed the renovation, using an architect to help draw up the plans. Green Building Store’s PERFORMANCE triple glazed windows and doors, with interstitial glazing bars, were specified for the project.

Background

The refurbishment project incorporated a number of energy efficiency improvements to the property, including: the creation of an insulated ‘warm roof’; insulation of ground floor and use of underfloor heating, improved cavity wall insulation on the ground floor; use of external wall insulation (EWI) under the hung tiles; and of course the use of triple glazed windows and doors throughout.

Triple glazed timber windows in a traditional style

As well as replacing the existing windows, there were a number of new openings created to help increase the light into the building. Sourcing windows that were both traditional in style and also met the energy efficiency requirements of the project was challenging. PERFORMANCE outward opening triple glazed timber windows, with timber glazing bars and interstitial warm edge spacers, were chosen for the project. The interstitial glazing bars used for the project avoid the ‘parallax effect’(where gaps in the glazing bars might appear if viewed side on). The opening style configuration was chosen to include small top hung windows, allowing easy opening for fresh air. Two of the windows have floating mullions so as to provide emergency egress as required by fire regulations.

Jerry commented: “I definitely wanted wood rather than plastic windows and needed a multi-pane Georgian style that would suit the Sussex hung tile vernacular. I was also looking for a window with U values substantially better than the UK building regulation requirements. I researched widely and attended many exhibitions and Green Building Store’s PERFORMANCE triple glazed range was the only range which combined my energy efficiency criteria with the traditional style that the project required.”

Jerry opted for FSC redwood engineered timber with RAL 6021 Pale Green on the exterior and RAL 1013 Oyster white on the interior.  “I did look at having oak but in the end I liked the stability of the engineered redwood combined with the durability of the finishes. I’m really pleased with the colours and appearance of the windows which work really well with the traditional hung tile style of the house”.

Jerry concluded: “The project aimed to combine good quality materials and great attention to detail to deliver a good quality refurbishment. Green Building Store’s PERFORMANCE windows provided the quality that I needed. I moved back in during September and the house feels much warmer and there are no draughts. In terms of after-sales support, Green Building Store was also quick to respond when I needed some adjustments after installation. My only regret is that I wish I could have used Green Building Store’s own fitting team to install the windows in the first place. Green Building Store were very helpful to deal with and very patient when I had to tweak the plans prior to ordering. I have already recommended Green Building Store to two other friends, who have been very happy with their windows as well.”
