Unique frame construction

The VELFAC slim frame design brings together the best of both worlds - the character of internal pine and the durability and low maintenance of external aluminium, with a frame which is only 54mm to increase the amount of daylight and enhance the view.

High quality wood

Frames, mullions and transoms are made of VACUMAT or Flow-coat-treated pine with waterbased acrylic paint containing anti-mould fungicide. The thickness of final paint layer, when dry, is 60-80μm. Wood is treated with a clear lacquer to enhance the warmth of the natural grain, or painted in one of a range of RAL colours to match the interior decor.

Durable aluminium

External sashes are made of aluminium extrusion alloy EN AW-6060 or EN
AW-6063, polyester powder coated to a thickness of 60-120μm and a standard gloss level of 77%, or anodised to a thickness of 20μm. The finish of the external aluminium sash is either a hard-wearing polyester powder coat in a wide range of RAL colours, metallic finish in RAL 9006 & 9007, or anodised silver or gold.

Insulating glass

Glass constitutes 62.2 percent of a VELFAC window. VELFAC manufactures double and triple glazing windows and the cavity between each pane of glass is filled by a non-toxic inert gas called Argon. Argon is extracted directly from the atmosphere and is nature's most common noble gas. Argon makes up 0.1% of a VELFAC 200 window and thanks to its excellent insulating properties, our windows are able to reduce dramatically the heat loss through the glass.

Designed for disassembly

Did you know that VELFAC windows are made of wood, aluminum and glass and that they can be easily disassembled at the end of their life cycle?
