Window Energy Ratings

Energy efficient windows are proven to save energy and reduce rising fuel bills, as well as lowering carbon emissions. The energy saved from efficient *A-rated* windows could offset the carbon used to manufacture the frames within months.

Why Energy Efficient Windows?

Poorly selected windows are a major source of heat loss in the home. Energy efficient windows help reduce your fuel bills and also help the environment through lower carbon emissions.

Window Energy Rating (WER) and What it Means

The WER rating reflects the energy efficiency of a window. As well as including the 'loss factors' such as U-value, it also includes the 'gain factors' such as solar heat gain. The rating covers the frame material, design, glass type and all other components.

Energy labels enable consumers to easily compare and select products based on the product's specific energy performance. Windows are graded on a scale from A down to G. The Energy Saving Trust recommends 'C' as the minimum standard for energy saving windows. Tradeframe supplies A Rated Windows as standard.

Today's growing issues on sustainability and the environment has increased our social responsibility.

How Sustainable is PVCu

The BRE has endorsed PVCu windows to have a 35 year life cycle and a recycleability of up to 7 times. 57% of the molecular weight in PVCu is salt, a sustainable mineral. The other 43% is oil based with PVCu using just 4% of the world's total oil stocks. All of our windows foils are an environmentally friendly calcium organic material. In short there is no such thing as a sustainable material, but it is the management of a material that is important.

Can PVCu Windows be Recycled?

Old PVCu windows and doors can be recycled and reprocessed. Tradeframe recycles off-cuts and post-consumer window frames.

We take seriously the environmental impact of our manufacturing process and we aim to recycle as much of the surplus material from our manufacturing process as possible.
