Window terminology




85 mm, 6-chambers, steel reinforced PVC profile designed for Canadian homes.

What are U-values?

Our Tilt & Turn windows are made of German PVC profiles and hardware.

We import windows and doors from Europe and ship across Canada and USA. 

All our windows are manufactured and certified according to EnEV 2014.

A window's insulation value is becoming increasingly important, particularly in light of the ever-more stringent demands of the German Energy Conservation Regulation (EnEV 2014). By insulation value, we mean the U-value (heat transmission coefficient), which records how much heat the element loses per m2 .

In a nutshell, this means:

The lower the U-value, the better the window is at retaining heat.

Ug = Value for the glass (g = glass)

Uf = Value for the frame (f = frame)

Uw = Value for the entire window (w = window)

When you purchase windows from our company, you don't have to worry about meeting legal requirements: all our Tilt & Turn windows already exceed the heat insulation requirements of Germany's Energy Conservation Regulation and  Canadian Energy Star requirements.
