PURe® Parallel Push Window

The PURe® parallel window has been designed to meet current and future building regulations, with impressive U values and thermal performances. PURe® is an evolved generation of aluminium window systems manufactured in the UK. It combines the long life and low maintenance of aluminium externally with a patented high insulation PUR foam thermal barrier. PURe® parallel windows are capable of accepting glazing up to 57mm thick depending on weight.

PURe® 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 Parallel Push Hinges.
