1. Top Level U-Value
Spoil your low level energy house with an Uw ranging from 1.2 to 0.8 W/m² Kº, depending on your demands

2. High Performance Insulation Glass
With a respectable Ug of 1.1 to 0.5 W/m² Kº

3. In-between Glass Lagging
The connection between the glasses is manufactured as a thermal insulating Thermo bar.

4. Extremely deep embedded glass
One of Hrachowina’s innovations: Due to the fact that the edge of the glass is more deeply embedded into the wood-aluminium is a better thermal insulation is possible.

5. Heat insulation pliers
An enduring insulating tape between the aluminium shell and the glass increases the thermal insulation at the edge of the glass.
