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.
