Doncaster, England – Leading fenestration designer and manufacturer Senior Architectural Systems has pledged significant investment in its manufacturing facilities as demand for its thermally efficient PURe® doors and windows continues to soar.

This ground-breaking patented* use of PUR as a thermal barrier means that PURe® aluminium doors and windows exceed current and will meet future Building Regulations.

Senior’s patented PURe® system is the first on the UK market to benefit from an enhanced thermal barrier manufactured from expanded polyurethane foam (PUR). Traditionally used in cladding and insulation products, the innovative use of PUR as a thermal barrier 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.
