Patent granted to PU foam frame system
June 2016

SENIOR ARCHITECTURAL SYSTEMS has been awarded a UK patent (Number GB252363.8) for its PURe range of windows and doors.

The new patented system is said to be the first in the UK have a thermal barrier manufactured from expanded polyurethane foam (PUR). Traditionally used in cladding and insulation products, its use in windows and doors gives the PURe range the potential to achieve U-values as low as 0.71W/m2K when calculated as a commercial CEN standard window and 0.93W/m2K when calculated as a CEN standard door.

The range has been extended by the launch of the PURe door system which includes folding sliding, inline sliding, lift & slide, single and double options.

Mark Wheatley, Senior Architectural Systems’ technical director said: “We are extremely proud of our PURe range and delighted to have been awarded a UK patent. Both the PURe windows and doors have been carefully developed, utilising the optimum amount of PUR insulation to offer excellent thermal performance with the potential to achieve the lowest possible U-values.”
