New generation energy saving glass

For use in cold climates

The "typical" window type depends on the area. In a cold climate the usual window is wooden frame (thick one) and 2 wooden sashes, in the outer sash there is a single glass, in the inner sash there is a double (or triple) glazed unit. The U-value of the whole window is about 1, 8 W/m²K. The inner sash has an insulated glass unit or two glasses in different sashes hinged together (they can be opened together).

The “typical” window type for cold climates can with vacuum glazing be superfluous and attributes to lower building costs and a high energy cost reduction.

The thickness of the Spacia vacuum double glazing is 8mm and performance extremely well in U-value of 1.2.

For use in historical buildings       

Most historical window frames cannot be adapted to support insulated glazing. In addition, the 15 mm or thicker insulated glazing panels conflict with the 4 mm original frames.

The Government Building Agency “Rijksgebouwendienst” (RGD) of the Dutch ministry of Housing, Spatial Planning and the Environment (VROM) is responsible for government buildings. RGD often faces problems of meeting insulation standards in historical buildings. Frequently, this requires the application of new technologies. RGD has identified vacuum glazing as a solution to the problem of window insulation in historical buildings.


For use in renovation projects for housing, the glass can be fitted in existing frames and replace single or low class energy saving glazing.
