Windows Exchange only uses the finest uPVC materials for our double glazed uPVC windows. That is why we use Deceuninck.

Energy Saving
Thanks to their clever design, uPVC window profiles are a very poor conductor of heat or cold. In very hot climates like the Asia Pacific region, this will reduce your reliance on cooling devices such as air conditioning. Of course, it also works the other way round. Keep out the cold and save on heating costs by choosing Deceuninck window profiles! Either way, you will feel the positive impact of up to 50% savings on your energy bill!
Chemical Resistant
Being made of exceptionally durable uPVC, Deceuninck windows are extremely resistant to pollution, diluted acids and alkalis. Deceuninck’s uPVC can be cleaned with warm water, a gentle household detergent and a soft cloth.
