Our AP134 tilt and turn windows are constructed using high-quality metal. The frames are made with aluminium alloy 6063 T5 and T6, complying with the guidelines of BS 7559:2001. The system uses recycled aluminium in accordance with ISO 14001. Our aluminium profiles have a life expectancy of up to fifty years and are 100% recyclable.
The extruded aluminium offers exceptional strength for a comparatively smaller area. Consequently, it can support larger spans of glass and lets in more natural light than a comparable timber or uPVC window.
