Even the best ideas can be improved
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.
Senior is constantly looking for new and innovative products, processes and service enhancements that will enable your next project to stand out from the crowd and make our world a better place.
embracing simplicity
The PURe® window range* is an aluminium window system that incorporates high insulation 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 0.71 W/m2K when calculated as a commercial CEN standard window.
Easy to manufacture using existing tooling, the PURe® window range is the new, simple way to exceed current and meet future building regulations.
developed to perform
From concept to design through to manufacturing, the PURe® window range has been developed with simplicity and performance in mind.
The innovative use of expanded polyurethane foam as a thermal barrier gives the range its impressive thermal performance, ensuring it exceeds current and meets future legislation.
With the capacity to evolve further, the PURe® window range is a next generation product that will benefit your projects both now and in the future.

taking the environment seriously
We are aware of the impact that buildings have on the environment, and we take a lifecycle responsibility for the products that we manufacture and deliver.
We minimise the risk of any chemical releases during manufacturing, and our aluminium systems are perfect for producing low maintenance, energy efficient windows and façades that have a long life.
Our metal of choice is aluminium. It recycles perfectly without losing any of its properties.;
helping you to achieve BREEAM credits
What is BREEAM?
BREEAM (Building Research Establishment’s Environmental Assessment Method) is the world’s foremost environmental assessment method and rating system for buildings, with 250,000 buildings with certified BREEAM assessment ratings and over a million registered for assessment since it was first launched in 1990. The system sets the standard for best practice in sustainable building design, construction and operation.
Ten Categories for a sustainable building
A BREEAM assessment uses recognised measures of performance, set against established benchmarks, to evaluate a building’s specification, design, construction and use.
Credits are awarded across ten categories based on the outcomes of the building assessed. The credits are then combined to provide a single score, achieving either a Pass, Good, Very Good, Excellent or Outstanding overall BREEAMrating.
Senior and BREEAM
Senior Architectural Systems product range has been developed with BREEAM at its centre. Our systems are proven to help you achieve a credible BREEAM rating. With many BREEAM rated projects already successfully utilising Senior products, we have a wealth of experience to assist the architect/designer in meeting their sustainability goals.
