The durability of aluminium and beauty of wood

VELFAC composite windows bring together the best of both worlds; the durability and versatility of aluminium and the beauty and warmth of natural wood.

All VELFAC windows are tailor made so they can be designed to meet your wants, tastes and needs thanks to our bespoke service. You can specify the size and shape of your new windows, mix and match hundreds of frame colours, and more.

Windows and doors retain a uniform appearance, whether they open or not, further enhancing the uncluttered feel optimised by the contemporary design. Not only will you experience more daylight, your house will also have a timeless appearance that you can enjoy year after year.
