We want to be kind to our world and let’s face it uPVC is an oil derivative but remains a great building product relative to other materials and importantly can be recycled and recycled again. 95% of our factory offcuts are recycled and we enable our customers to recycle the windows and doors they take out of homes to replace with new ones. UPVC can be recycled up to 10 times, and even becomes stronger after recycling. We work closely with our key suppliers Eurocell and VEKA to ensure that the products we make have a high content of recycled materials. Out latest product, ELITIS ECO leads the way in this field and is made from 80% recycled uPVC. Aluminium is the most recycled material in the world and we have the very best recycling procedures in house in minimise any waste.
