High-insulation window cuts heat loss by up to 52%

The award-winning PRO TEC 7 window enables homeowners to turn down the heating because it lets more heat in than it lets out. Whereas windows are normally the main culprit where heating bills are concerned, the high-insulation frames of the PRO TEC 7 increase the area of the window pane, which in turn increases the admission of daylight – and also heat – to the building,” says PRO TEC’s Managing Director Bjarne Haulrik.

According to our calculations, the new window will cut the amount of energy used for heating by as much as 52% depending on building architecture and type of glass used. This benefits both the environment and the householder’s economy,” says Bjarne Haulrik, founder and Managing Director of Pro Tec.

“Our new window provides double the insulation of conventional low-energy windows on the market. With PRO TEC 7 it is possible to reduce the need for space heating by up to 52% compared with conventional, modern low-energy windows. This saves on domestic heating bills and significantly reduces carbon impact. We are therefore certain the window will be a success, also in the export market,” says Bjarne Haulrik.

The designers of the new window set out to create a window that would eliminate the thermal bridging that results in heat loss and causes condensation to form inside the glass. Up to half the energy used in heating contemporary Danish homes disappears through windows and doors, principally via the frames and sills, which until now have performed poorly in terms of insulation, and significantly worse than the glass itself.

“PRO TEC 7 insulates so well that the U-value for the total window structure is as low as 0.76 W/m²K. This puts us way ahead of the tougher new requirements in the Danish building regulations, and in the building regulations of the rest of Europe, where Uw requirements are currently being tightened,” says Bjarne Haulrik.

Compatible with modern architecture
The window system is designed to completely eliminate double frames and clumsy structures, the profile being 10 times stronger and more rigid than PVC. In the context of the building facade the window presents a slim and stylish aspect that complements Scandinavian architectural taste, but which has also been positively received elsewhere in Europe.

“The architects retain their freedom of action. They can realize their design ambitions for the building without compromising the energy envelope dictated by the new and more stringent regulations. So they can continue designing buildings with large areas of glass in which the view is uninterrupted by double frames and where the transition between outside and inside almost disappears,” says Bjarne Haulrik.

The PRO TEC 7 window is made of GUP composite. Even equipped with extra-insulating triple glazing for low-energy houses the window remains slim and elegant and has an exceptionally low U value.
