Energy Efficient Products
To cater for the greater emphasis on energy efficiency in homes, Design Windows has three ranges of thermally efficient windows and doors. Our project managers encourage top performing joinery to ensure buildings are as energy efficient as possible.
The Klima Series of windows and doors is a uPVC window system that when combined with Low-E double glazing is rated to a maximum 6 energy stars under Weers (Window Energy Efficiency Rating System). They are made from a highly durable uPVC, an environmentally-friendly lead free formulation. The Metro ThermalHEART and Residential ThermalHEART ranges when combined with low emissivity double glazing significantly reduces home heating and cooling costs. All ThermalHEART windows and doors have a nylon insulator incorporated in every aluminium profile which provides a highly effective barrier for minimising heat loss and the development of condensation. ThermalHEART ranges offer up to 35% more thermal efficiency than standard double glazing.
Double glazing options also increase the energy performance of windows and doors, making for a more comfortable home year round. Low-emissivity glass allows in light and heat, reducing heat loss by up to 30%. Combined with an inert gas such as Argon, heat loss can be reduced further by up to 9%.
