THE GVG 90 Frame
The award winning GVG90 frame, a Passive House Institute Certified Component, gives the best performance of all, in the world of windows, starting with a Uf value of 1.0 W/m2K. This is achieved with multi-layered insulation and gaskets to insulate the frame totally.
Add to that an airtight seal, which keeps all of the drafts out and all of the heat or cool in, minimizing heating or air conditioning costs and associated pollution. Next, an RC3 grade security locking system will keep even the professional burglars out and also bring your insurance quotes down.
Finally, it uses our vacuum insulated glass units, and also our thicker vacuum solar glass units, and secretly houses the associated electrical wiring with a side feed for your supply, when solar is required. Priced to compete with triple glazed good quality aluminium windows, there is only one choice, the Werkman GVG90.
Werkman GVG90. Far Greener | Far Better | Far Longer.
