If you want to save energy you don’t have to freeze. Instead, you need to make sure that the heat stays where it belongs: within your own four walls. One of the most important means of achieving this is by using the right windows. And, the rate of progression in the area of thermal efficiency and energy saving technology in recent years has been more rapid for windows than any other component of the building envelope, not least thanks to innovative Weru technology.
All windows in the new AFINO family have higher than average thermal insulation values. But this wasn’t enough for us. When you opt for an Energy package tailored to your requirements you therefore have the opportunity to increase the thermal efficiency of your window further, reduce energy costs and preserve the environment.
We have effectively bundled the most efficient active thermal insulation measures in our three Energy packages. From thermal glazing with ultra thin coating including triple-glazed window engineering to heat-insulating spacers through to the innovative Energy profile with foam-filled insulating chamber, whichever method you choose, you can increase the thermal efficiency of your window by up to 55 % compared to a window with basic double glazing.

Weru Supra-Therm (Ug value 0.5) – Increases the energy efficiency of the glazing by 55% compared to basic glazing by using triple thermal glazing with two coated panes filled with inert Argon gas.
What Does The U Value of A Window Mean?
This value (previously known as the k-value) is also known as the thermal transmission coefficient and states the rate of heat flow through the window when the temperature difference between the inside and outside remains constant. The U value of the window is calculated from the thermal transmission coefficients of the frame and sash profile (Uf), the glazing (Ug) and the glazing edge compound used. The following applies as a basic rule: the lower the U value is, the more effective the thermal insulation properties of the window will be.
Can Windows Save Energy?
The insulating glass in the Energy packages helps you save on heating costs. The Ug value defines the loss of thermal energy to the outside and the g value defines how much energy reaches the interior via the sunlight. The higher the g value is, the higher the energy yield will be as a result of incoming sunlight. Weru windows have a low Ug value and a g value of up to 60 % and therefore create a pleasant living climate without cold zones. They also give you the sense that your money is not being sucked out of the window!
