Newly available from leading sustainable building envelope specialist, Schueco UK Limited, is the Schueco AWS 90.SI+ window, one of a growing number of Schueco window, door and façade systems to have received full Passive House Certification.

The window’s outstanding thermal performance – it delivers a U value of 0.8 W/m2K with 0.7 W/m2K triple glazing – is the result of advanced insulation technology and enables it to make a positive contribution to the overall energy efficiency of a building.

In addition to its attractive appearance, Schueco AvanTec concealed fittings impart an impressive degree of security, helping the Schueco AWS 90.SI+ system to deliver either RC 2 or RC 3 levels of burglar resistance to EN 1627.

Two other windows in the AWS 90 window range, the Schueco AWS 90.SI+ Green and the Schueco AWS 90 BS.SI+, have thermal insulation to Passive House levels. Like the Schueco AWS 90.SI+, they are able to satisfy exacting structural requirements while delivering the greatest possible architectural freedom.

The Schueco AWS 90.SI+ Green is part of Schueco’s new generation of ecologically friendly window systems. It incorporates polyamide insulating bars, which together with its foam and gaskets, include significant proportions of renewable raw materials in their composition.

The Schueco AWS 90 BS.SI+ offers a complete and elegant solution for concealed vent windows in single- and now double-vent designs. It features slender 77 mm face widths and has a basic frame depth of 95 mm.
