Energy efficient windows
VELFAC composite aluminium / timber frames are designed to deliver maximum energy efficiency. Double glazed as standard (with triple glazing an option), a VELFAC window can achieve a U-value as low as 0.8W/m2K.
U-values, your windows thermal efficiency indicator
In simple terms, the U-value measures the amount of heat allowed to escape through a window (heat loss). In both cold and warm climates good U-values are important measures for understanding the amount of energy that is needed to keep a comfortable inside temperature. When assessing a window’s ability to retain heat (insulation), the lower the U-value the better.
Choosing new modern energy-efficient windows, you’ll take advantage of sunlight and avoid excessive heat loss through the pane. This could save you up to 30 percent on your heating bills compared to older windows.
The VELFAC slim frame maximises solar gain and natural light – reducing dependency on artificial heating or lighting – and helps reduce U-values further, as glazing is usually more energy efficient than the frame.
A choice of window options
To maintain the energy efficiency of your property, VELFAC offers a range of standard features and optional extras including:
- double-glazing as standard
- optional triple-glazing to ensure exceptional weather or acoustic insulation
- glazing units filled with argon gas, further improving insulation
- optional glass coatings to reflect heat back into the interior, or to control solar gain
Harnessing 'good energy' with VELFAC
What is good energy? When we talk aboutwindows and energy there’s a lot more to consider than just U-values. A window is not like a brick wall, designed to keep the cold out and heat in. The latest energy efficient window can actually contribute more energy to a building than is lost through the window. If you want to know more about how to maximise the good energy in your house, read the Good Energy brochure.
