We continue to stand at the forefront of this campaign, setting ambitious ecological goals, working towards declaring carbon emissions for both our business and our products. Bioregional state that approximately one quarter of our CO2 emissions in the UK come from housing; and so in making timber windows and doors for housing and construction our responsibility to ensure our products are sustainable and energy efficient is greater than most.

As public awareness on issues such as plastic waste, chemicals used in uPVC production, energy usage and the carbon footprint of the products we buy becomes more mainstream, those companies that can supply supporting product information will be well placed.
