Specify the right glass for every room

When choosing new windows and doors, It's not just the number of glass panes that you have to consider. Glass is a complex substance with almost limitless variations, therefore is no such thing as the perfect pane of glass – instead, glass properties must be carefully balanced so they meet the needs of a specific window and its location.

VELFAC clear - standard option

VELFAC CLEAR glass (the standard option) delivers a light-filled interior and a clear view of the outdoor. Excellent insulation results from a heat-reflective coating applied to the inner glass surface, and the use of argon gas within the glazing cavity.

A standard VELFAC 200 double glazing window measuring W1230 x H1480mm with CLEAR glazing, achieves a U-value of 1.47 W/m²K. For even better insulation, you can choose a VELFAC ENERGY unit, which feature a combinations of triple-glazing, argon gas filling and a ‘WarmEdge’ spacer, that can achieve U-values as low as 0.80 W/m²K.

VELFAC SUN - solar control

In full sun, windows can generate a lot of heat (known as solar gain), especially if units are large or installed on south or west facing facades. VELFAC SUN25 glass features a neutral coating which reflects up to 60% of the sun’s heat while allowing plenty of natural light to enter the room. For additional solar control, VELFAC SUN35 features a slightly darker coating which (although transparent) will slightly affect the appearance of external colours.

VELFAC DÉCOR - opaque privacy glass

If privacy or security are essential, VELFAC DÉCOR opaque glass is the ideal choice. VELFAC DÉCOR is available in five different designs, including matt foil lamination to give a sand-blasted appearance and reduce risk of injury if the glass is broken. To ensure excellent performance of the VELFAC window unit, we recommend that VELFAC DÉCOR glass is installed as the external or middle layer when combined with VELFAC CLEAR, or as the internal or middle layer when used with VELFAC SUN.

VELFAC SOUND - noise reduction

Efficient glazing is fundamental to noise control, and although double glazing can reduce external noise, thicker or different combinations of glass can significantly improve acoustic performance. The Rw rating indicates the number of decibels by which a window unit will reduce apparent noise - a standard VELFAC double glazed window achieves Rw32, which can be increased to Rw41 by adjusting the thickness of the glass and the glazing rebate.

VELFAC SAFETY - safety glass

Safety glass must be installed where there is a risk of impact and injury (safe breakage glass), or where glass is used to create a physical barrier (containment glass). Depending on location and need, VELFAC SAFETY glass can be specified as either laminated or toughened. VELFAC SAFETY glass is designed to break harmlessly, to reduce the risk of injury, and can also provide additional security as it can withstand considerable force.
