Why is sustainability so important?

Here at TWS, we know we all need to do our bit to try and lead more sustainable lives. Being more sustainable with your home improvements helps to look after the environment, but you’ll also enjoy lower energy bills, increased energy efficiency and your home will require less maintenance over time.

Is uPVC sustainable?

Thanks to advances in recycling and product innovation, uPVC is now widely recognised as a sustainable option for the construction industry. Old uPVC window frames can even be recycled and repurposed up to 10 times without the quality or performance deteriorating. In fact, half of the construction of our uPVC windows is made up of post-consumer recycled uPVC!

Thermally efficient

uPVC's exceptional thermal performance means our uPVC fittings will significantly reduce your carbon footprint. In addition to increased comfort levels, you will not need to use as much fuel on your central heating system in order to keep your home warm. By replacing all the windows on a detached home with A+ rated windows, it’s actually possible to save up to £110 a year on heating costs. Here at TWS Leeds, our windows and doors excel in terms of thermal performance, meaning you can enjoy similar savings for your property.

Energy ratings and sustainability

Windows and doors are rated on a scale of A++ to E, with A++ being the most energy-efficient and E being the least. Since 2010, replacement windows must have a minimum rating of C. However, our windows far exceed this minimum value.
