Benjy Simmons: Stärke Windows

‍“We do windows and doors because of the effect it has on the building performance – the most significant elements... Up to 50% of heat loss and up to 70% of heat gain is through your windows.”

Brent & Claire Chatterton: Chatterton Homes

‍“Windows can contribute to heat loss through thermal bridging, and allow uncontrolled air movement through inadequate seals, which encourages draughts and allows allergens and moisture into the home. High performing windows mitigates these risks through better seals and the use of less conductive materials.”

Julie Villard: Eco Design Advisor Christchurch City Council

‍“Windows can contribute significantly to a building’s heat losses... They need to multi-task, bringing in light, allowing solar gain as free heat, and limiting heat loss in winter.”

‍

Bob Burnett: Superhome Movement Co-founder

‍“I’m really interested in achieving better performance with the windows because that’s where most of the heat loss is.”

Darren Ballantine: Metro Glass

‍“Any change in improving the efficiency of a home is a step in the right direction – windows are acknowledged as being a leading cause for both the loss of heat out of a home as well as contributing to heat gain – so the windows are also a leading opportunity to gain thermal performance within a home and make it a more satisfying and happier place to live in.”
