Modern Glass Technology by IQ Glass

Exceptional Insulation

The key feature of a PassivHaus Window is the exceptionally high levels of thermal insulation that can be attained.

Using triple glazing as standard a PassivHaus Window can achieve Uw values of as little as 0.69 W/m2K to enable them to be used on PassivHaus projects as well as Eco housing design and Zero Carbon projects.

As well as incomparable thermal performance PassivHaus Windows have to have outstanding resistance to wind, water and drafts to create a complete seal against the elements.

Beautiful Design

PassivHaus Windows are created with a highly insulating composite frame to ensure the highest levels of thermal performance are achieved. With an aluminium external finish the composite windows are easy to maintain and the aluminium surface can be powder coated any colour to suit your design.

Internally you will see a beautiful timber frame, stained or painted to your design preference. Timber frames create a softer modern internal finish preferred by many and create a perfect edging to any window opening. 

A matching opening door design is available to create a full PassivHaus glazing design as well as an XL lift and slide door.
