About the SW60 TruEnergy System
The SW60 TruEnergy is a thermally broken aluminium window system with a 70mm frame depth designed to meet Document L 2016 requirements. U-values of 1.2 W/m²K (with 0.7 centre pane value) or 1.5 W/m²K (with 1.0 centre pane value) make it suitable for new builds and refurbishments where thermal compliance is required. The system is available in side-hung casement and top-hung configurations, with French casement options also available. Maximum tested sizes are 750mm x 1400mm for side-hung and 1400mm x 1400mm for top-hung windows. PAS 24 security and Secured by Design accreditation provide enhanced security credentials for residential and commercial specifications. The SW60 accepts 28mm or 36mm glazing, with flush or stepped external appearance options and both internal and external glazing methods. Slim profiles reduce sightlines for a clean, modern appearance. We fabricate SW60 windows with triple weather seals, multi-point locking, concealed or visible drainage, and child safety restrictors as standard. Dual-colour options are available — different colours inside and out.
