PURe® Parallel Push Window

The PURe® window range is a range of aluminium windows which uses an innovative, enhanced thermal barrier manufactured from expanded polyurethane (PUR) allowing ultra-low U-values to be achieved.

The aluminium windows are fully compatible with Senior doors and curtain walling and are available pre-finished in an almost unlimited range of colours and finishes both inside and out. With a generic Green Guide rating of ‘A’ for use in commercial projects and a life expectancy in excess of 40 years, the product is 100% recyclable and has been designed to meet the Passivhaus standard.

The window is 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 screw ports or shear blocks. A proprietary sealant is used on all metal joints in line with good practice.

Opening window frames are designed to be inserted directly into the outer frames using butt hinges.
