Beautiful design, excellent performance

Find the right balance with VELFAC

A window is not like a brick wall, where the focus is simply on the ability to keep the cold out and the warmth in. Instead, high quality windows can actually contribute to improve the indoor climate and retain more heat into the home, reducing the energy need, making the homes you are building the best investment for potential home buyers.

High energy efficiency

Windows and doors play a decisive role in any building's energy consumption. The VELFAC composite glazing system is designed to meet – and exceed – current building regulations for energy performance, reducing the need of artificial lights and heating and supporting your low-energy construction targets.

Your choice of windows can make the difference

With U-values that can go down to 0.8W/m2K for triple glazing, VELFAC windows ensures excellent performance, together with maximum daylight.

Our team can help you specifying the ideal combination of window and glass to maximise air quality and thermal efficiency of your Housebuilding project.

Besides the window's basic energy performance, there are 6 primary factors to consider in low energy buildings.

The primary factors to consider in low energy buildings

  • The windows’ orientation in relation to the sun
  • Sun screening and shading
  • The glass ratio
  • Installation methods and thermal bridges

Achieve acoustic control

VELFAC windows and doors are designed to reduce the level of unwanted noise like for example, heavy traffic.

Minimising noise pollution with VELFAC

The noise level within most rooms of a family house should not exeed 30db. If for example loud traffic noise amounts to 65-70Db, the building must be able to reduce the noise level by 35-40Db.

A standard VELFAC double glazed unit achieves Rw32, which can be increased to Rw43 by adjusting the thickness of the glass and glazing rebate.
