About VELFAC

Founded in Denmark over 60 years ago, VELFAC is widely recognized as a pioneer in composite window and door design. As part of VKR Holding, alongside sister company VELUX, VELFAC builds on decades of Scandinavian innovation focused on maximizing daylight, fresh air, and healthy indoor environments. Often referred to as daylight engineers, their systems are purpose built to transform living spaces through clean design and superior performance.

At the heart of VELFAC design is the signature composite frame, combining a weather resistant, low maintenance aluminium exterior with the natural warmth and beauty of real wood indoors. Because fixed and opening frames share identical, ultra slim profiles, VELFAC creates a seamless visual aesthetic across the entire property. We at Keystone Supplies work directly with homeowners, architects, and builders to supply and install these world class glazing systems with expert precision.

VELFAC Composite Windows

VELFAC composite windows and doors combine low maintenance external aluminium with natural internal timber, and are renowned for their contemporary style, impressive durability, excellent insulation, and secure and sustainable design. The slim frame maximises natural light, and uniform sightlines give every unit an identical external appearance. All VELFAC windows are manufactured bespoke, and each frame element can feature a different finish.
