What are U-values?
A window's insulation value is becoming increasingly important, particularly in light of the ever-more stringent demands of the German Energy Conservation Regulation.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 one of our business partners, you don't have to worry about meeting legal requirements: aluplast windows already exceed the heat insulation requirements of Germany's Energy Conservation Regulation. Find out more today by visiting your local window fabricator.
Specialist terminology for window types
There are lots of different types of window. They differ depending on their opening mechanism or the number of sashes, e.g. single or multi-sash windows, sliding windows, etc.
When it comes to selecting a window, the opening mechanism can play a decisive role if you're looking to make the most of your space or want to let in as much as air as possible.
