W30 datasheet

The W30 range of steel windows is a slimline derivative of the W20 range suitable for double glazed domestic and light to medium- duty commercial applications. It incorporates double weatherseals plus fully drained and ventilated glazing and with its ability to house 18mm sealed units, whilst offering very narrow sightlines on opening windows, allows W30 to attain an exceptional grade "B" window energy rating (WER) under the BFRC's (British Fenestration Ratings Council) rating scheme.

This makes the range particularly suitable for replacing existing SMW (Standard Metal Window) installations to upgrade them to fully Building Regulation compliant standards whilst maintaining the slim elegant sightlines of the existing windows. Equally, they offer the specifier of extensions or new build projects an un-rivalled slim sightline product with outstanding performance.
