PassivGlas™ Linear laminate is an advanced fenestration technology that involves creating a highly insulating retrofit unit by laminating PassivGlas™ vacuum insulated glazing (VIG) with an EVA interlayer and a fully toughened additional glass leaf.

Unlike traditional double-glazed windows, PassivGlas™ Linear laminate adds security alongside the benefits of minimize heat and acoustic transfer through the unit.

Features and benefits:

PassivGlas™ Linear laminate can be manufactured into unit thickness of 13.65 mm and upwards, to be utilized into existing frames, allowing endless retrofit possibilities.
Offers reduced U-values to as low as 0.50 W/m²K, whilst maintaining up to 77% light transmittance.
The minimum glass unit thickness available in PassivGlas™ Linear laminate is 13.65 mm with a weight of 31.5 kg/m².
PassivGlas™ Linear laminate can achieve an R_w: 36 dB (UKAS accredited).
PassivGlas™ Linear laminate can comply with Building Regulations Approved Documents Q, O, E and L.
PassivGlas™ Linear laminate is suitable for existing frames which are in perfect working order, but require an enhanced overall thermal and acoustic performance.
Can be leaded to match existing or new designs.
Free solar energy, leading to lower energy consumption.
No evacuation port to impede view.
Appearance of monolithic glass.

Overall frame U-values as low as:

Aluminium 0.8 W/m²K.
Steel (thermally broken) 1.2 W/m²K .
Timber 0.78 W/m²K.
PVC-U 1.0 W/m²K.
