Following on from the success of its thermally advanced PURe^® window system, leading fenestration designer and manufacturer Senior Architectural Systems is once again set to break the mould with the launch of its innovative new PURe^® door range.

Available as folding sliding, inline sliding, lift & slide, single and double options, the new patent-pending PURe^® range features the pioneering use of an enhanced thermal barrier manufactured from expanded polyurethane foam (PUR). When calculated as a CEN standard door, the new PURe^® system can achieve U-values as low as 0.93 w/m2k. By offering significantly lower U-values than other aluminium doors currently available, PURe^® doors can make a substantial improvement to the overall carbon footprint of a building which in turn can lead to a reduction in energy bills.

Offering aesthetically pleasing features across the full portfolio, Senior’s new PURe^® range is easy to manufacture using existing tools and has been cleverly designed to be simple to adjust and install. Also boasting exceptional design flexibility, the new PURe^® doors are available in a full range of standard RAL colours. For more bespoke projects, colours can be matched to specific requirements and there is a dual colour option so that different shades can be specified for the internal and external surfaces. Ideally suited to a wide range of applications, the PURe^® doors are also available in a wide choice of configurations, including the choice for further thermal enhancement, a robust heavy duty lift & slide option and either standard double glazing or high performance triple glazing units.

As the PURe^® doors are competitively priced compared to less thermally efficient aluminium doors, a building’s carbon calculations can be improved without increasing costs and additional savings can also be made by reducing the need for features such as photovoltaic roof panels or expensive under floor insulation. The new door range perfectly complements Senior’s ground-breaking PURe^® window system, which offers U-values of 0.71w/m²k when calculated as a commercial CEN standard window.

Designed to exceed current and meet future Building Regulations, PURe^® doors have been developed to meet British security standards and have been fully tested to BS6375 parts 1, 2 and 3 Annex A.
