About Deceuninck

About us

Introduction to Deceuninck

With a heritage spanning over 80 years, Deceuninck is at the forefront of innovative, high performance windows and doors. From our headquarters in Belgium and UK head office and production in Calne, we supply award-winning PVC-U windows and doors for the residential, commercial and housebuilding sectors.


Reliability, innovation and sustainability

Reliability, innovation and sustainability are the cornerstones of our business. Deceuninck’s products are tried and tested for intelligent design and long-lasting performance, and we are committed to developing sustainable products for tomorrow’s world. We recently commissioned a new €13 million high-capacity PVC-U recycling line at our compounding facility near our global headquarters in Belgium. The new recycling facility quadruples our previous recycling capacity to process up 45,000 tonnes of material a year, reinforcing our pledge to the circular economy.

Deceuninck’s leading product range includes the Heritage Window Collection, a selection of Flush Sash, Chamfered and Sculptured windows and doors, all available in choice of 30+ colourways from stock and 20 further colours on very short lead times. Our 5000 composite window with award-winning Linktrusion™ Technology is a popular choice for commercial applications because it offers very slim, very strong windows and doors in a wide range of colours.


Strengthening our relationship of trust with our customers and maintaining their confidence as a true partner is an absolute must.


Cutting-edge thinking has always been in our DNA, but we want to take it a step further. Our aim is to become a solution provider to our customers, by offering service beyond the product and giving support in multiple ways.


We are a leader in the ecorevolution and want to continue to invest in the circular economy as a leading brand in this matter. You can read more about our sustainability promise by viewing our page The Future Is Safe In Our Hands
