The tilt before turn (TBT) window from fenestration systems specialists Sapa Building Systems’ Dualframe 75 Si range is the first aluminium window to be given the new A++ Window Energy Rating (WER), the highest available rating in the UK.
Awarded by the British Fenestration Rating Council (BFRC), the rating was originally launched at the start of June, giving manufacturers four months to develop products. However, such is the future proofing strength of Sapa’s Dualframe 75 Si range, the TBT window was already compliant.
The entire suite of windows included in the class leading range all achieve the A+ WER, the only aluminium range to do so. It has continued to push boundaries since its launch in 2010 and Sapa’s commitment to exceeding energy and security targets set out in the Building Regulations and national standards is underlined in the awarding of the A++ rating to the TBT design.
“We are again leading the way with energy ratings for aluminium windows,” said Mark Robinson, Technical Director at Sapa Building System. “This latest award follows on from similar accolades in 2006 when a solution from the Dualframe 75 range was the first aluminium window to be awarded an A rating, which was then followed in 2013 with the Si A+ WER.
“This new addition to the rating system will not only offer fabricators more choice, it will also create significant energy savings, helping to reduce bills. The TBT window will reduce solar gain in the summer while helping to keep buildings warm in the winter. With the next expected revision of Part L of the Building Regulations expected in 2019, we are ideally placed to be able to meet any projected tightening.”
“BFRC is delighted at the take up for the new A++ rating for windows,” comments BFRC Managing Director Chris Mayne. “Since the announcement that BFRC was accepting applications for the new A++ band we received simulation reports from far more companies than we expected. This has resulted in the launch of the first batch of A++ window products and we look forward to seeing how they perform in the market.”
The Dualframe 75 Si TBT window is an ideal solution for high rise or commercial applications, and combines ventilation with easy cleaning and large span openings. The safety locking handle is key operated and the key must be inserted in order to access the turn mode. Once the window is closed, it automatically defaults to the tilt only mode.
