Window of opportunity for Pure thermal efficiency

Glazing systems designer and manufacturer, Senior Architectural Systems, has launched Pure, a ‘revolutionary’ new aluminium window system that, according to Senior, can help specifiers achieve exceptionally low ‘U’ values and high thermal performances.

The new Pure window range is the first on the market to benefit from an enhanced thermal barrier manufactured from expanded polyurethane foam (PUR).

Traditionally used in cladding and insulation products, the use of PUR as a thermal barrier in windows is said to give the Pure system the potential to achieve ‘U’ values as low as 0.8w/m2k and according to Senior, is both fully recyclable and safe to handle.

Designed to exceed current and meet future requirements, the Pure range is reportedly easy to manufacture using existing tools to provide the simplest yet most effective solution to the specification of thermal-efficient windows. With a generic Green Guide rating of ‘A’ for use in commercial projects and a life expectancy in excess of 40 years, Senior’s most recent product innovation has also been developed to meet the PassivHaus standard cycle.

Both double and triple glazing options, up to 57mm to maximise thermal and acoustic performance, are catered for, with the additional support of specification via Senior’s dedicated glazing division, Senior Glass Systems, being available.

Described as ‘competitively priced’, Pure is reportedly suited for use across the sectors, from education to healthcare, commercial to domestic, refurbishment and new build projects.

Senior’s Pure range also boasts a number of environmentally friendly features and is manufactured using aluminium, which offers ‘cradle to cradle’ recycling. The PUR thermal barrier can also be re-used as fillers for other products, with no requirement for landfill.

The Pure range is available in a range of standard finishes, both painted and adonised.
