Sun Trade Windows have recently announced the introduction of the new REHAU TOTAL70 five chamber system to their range of thermally efficient windows. The new system boasts greater versatility for both commercial and domestic projects by offering the very best in both window energy ratings and U-values.

The new Sun range, branded as ‘The Ultra System’, goes far beyond the standard A, B and C WER ratings and offers the very latest A+ and A* ratings.

Steve Graves, Head of Business Development for Sun, shared his belief in the new range. He said: “Since 2010 the market place has been flooded with end users often misinformed on product specification and on the accurate benefits of window energy ratings. Many companies who offer standard ratings do so by utilising basic components and achieving the bare minimum on the required energy index. In contrast, our Ultra System boasts energy index scores as high as 12, guaranteeing that the rating reflects the real benefit to the end user.”

Utilising glazing options from both Planitherm and Pilkington, Edgetech Super Spacer, REHAU TOTAL70 five chamber profiles and Mila hardware, the versatile new range is backed by the very best brand names in the industry.

In addition to the new A+ and A* ratings, Sun’s new range is completed with their all new ‘Ultra 8’ offering. This features a 3.5mm bead housing a 44mm triple glazed unit and a perfectly crafted five chamber profile and has achieved a market leading U-Value of 0.8.

Steve Graves is keen to emphasise the additional benefits: “Discerning home owners appreciate the need for low U-Values and understand the real benefits they offer. This dynamic new product from Sun gives them the exceptional performance they demand, backed up by all the relevant testing and certification.”

The new Ultra System from Sun far outperforms the industry standards on thermal performance but it also does not compromise on aesthetics. The profile has perfectly cut lines and a smooth high gloss finish making it ideal for both domestic and commercial applications. In addition, the range is available in as little as seven days with a wide choice of colours available.
