extract the raw material and transform it into another product. In fact, using recycled aluminium saves up to 95% of the energy required for primary aluminium production. This makes it an extremely sustainable product that has a much lower carbon footprint during manufacture, something that is becoming ever more important as the construction industry moves towards a low-carbon, zero-waste solution. Aluminium products made using recyclable materials present consistently low environmental impacts while offering strength, durability, stability and reduced weight compared to steel. Among other benefits it has to offer, natural corrosion and UV resistance enable the specifier to forecast with accuracy the cost of maintenance over a system’s design life. So, for those specifying metal window and door systems, there is clearly an incentive to use a raw material that can be reused on an almost infinite basis. In terms of enabling building designs to achieve the highest level of BREEAM certification, aluminium can also provide tangible benefits when calculating a building’s environmental, social and economic
sustainability levels, using standards developed by the Building Research Establishment. In addition, aluminium also enhances specific aspects of a window or door’s technical performance, such as its thermal, acoustic and energy efficiency. To achieve greater efficiency in terms of thermal transmittance, high performance window and door design is becoming increasingly sophisticated. As already stated, aluminium can be formed into complex and diverse profile shapes, a feature that makes it ideal for contemporary architectural design. Aluminium’s permanence, its flexibility and versatility will pave the way for products of increasing environmental value. If we add to this the widely accepted ecological argument against the use of PVCu and the tangible evidence of the sustainability and thermal performance provided by aluminium window and door systems, with a design life that has already spanned several decades, the case for the use of aluminium window and door systems has never been stronger.

recently
opened a dedicated thermal improvement manufacturing facility in Rotherham to support its main manufacturing facility in Denaby, near Doncaster, and its distribution site in Livingston, Scotland. The new site has seen production of Senior’s patented PURe® range of low U-value aluminium doors and windows double, helping to bring down lead times and deliver the award-winning Part L compliant solution to more of Senior’s fabrication and specification customers. The unique range, for which Senior recently won a King’s Award for Enterprise
in innovation, 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/m2 K when calculated as a commercial CEN standard window and 0.93W/m2 K when calculated as a CEN standard door.
Senior is planning further investment in the new site and has already expanded its local workforce with the recruitment of four new operatives. The speed and efficiency of Senior’s production is set to increase further with the addition of a second high pressure polyurethane injection system later in the year, as well as a new double grooving machine and spiral wrapping machine.

windows and doors within Senior’s extensive range will also be moved to the Rotherham site in due course. This will support the work that is set to continue at Senior’s main manufacturing and national distribution centre in Denaby. Together with Senior’s established sites in South Yorkshire and Scotland, the new facility has increased the company’s overall UK manufacturing capacity to 220,000 square feet.
