PURe® Overswing Window

Aluminium windows which use an innovative, enhanced thermal barrier manufactured from expanded polyurethane (PUR), allowing ultra-low U-values to be achieved. This top-hung window can initially open for ventilation and when needed, can fully reverse to allow the outside of the window to be cleaned easily from the inside.

With a generic Green Guide rating of ‘A’ for use in commercial projects and a life expectancy in excess of 40 years, the PURe® window range is 100% recyclable and has been designed to meet the Passivhaus standard. Tested to PAS24, BS 6375-1, BS 6375-2 and BS 6375-3.

Features and benefits:

• High performance polyurethane thermal barrier providing U-values as low as 0.93 W/m²K when calculated as a domestic CEN Standard window.
• Able to receive double or triple glazing up to 50 mm for maximum thermal and acoustic performance.
• Available in an almost unlimited range of colours and finishes both inside and out.
• Opening window frames are designed to be inserted directly into the outer frames using friction stays.

Construction:

Constructed using mitred corners, joined with crimped cleats; alignment chevrons assist in clean, accurate mitres. Integral transoms and mullions are scribed around the outer frames and fixed with either screwports or shearblocks. A proprietary sealant is used on all metal joints. Opening window frames are designed to be inserted directly into the outer frames using butt hinges or tilt/ turn mechanism.
