The pure window range has been developed by Senior Architectural Systems, one of the largest and most respected fenestration companies in the UK today. The system is the next generation of evolved products, to exceed current and meet future legislation.

The Pure Range is an aluminium window system that incorporates high insultation polyurethane foam (PUR) as an innovative thermal barrier. Already used for many years in the construction industry to provide insulation, PUR is fully recyclable, safe to handle and gives ultra high thermal performance. Its ground-breaking use as a thermal barrier in windows is set to revolutionise the market, giving U-values as low as 0.8 W/m2k to meet the PassivHaus standard cycle, and with a life expectancy in excess of 40 years.
