Technical benefits

When compared to non thermally broken single glazed frames, Thermal Heart™ delivers a 130% improvement in thermal performance. When compared to non thermally broken double glazed frames the improvement is 35%.

WERS (Windows Efficiency Rating System)
WERS is an industry rating system that outlines the minimum value for the thermal performance of frame and glass combinations.

‘R’ Value
The measure of total thermal resistance of a building element. The larger the ‘R’ value the better the performance.
Thermal Heart™ exceeds the WERS ratings.

Energy use in the average New Zealand home
In the average New Zealand home, space heating amounts to about a third of total energy use. The improved R value provided by Thermal Heart™ can lead to lower heating requirements, and therefore lower total energy use.
