The newly launched TwinSash can achieve a U-value of just 0.38. Halo's new window system is unlike anything else currently available on the UK PVC-U market.The pioneering window system supplier has unveiled the 'TwinSash' which can achieve a U-value of 0.38 W/m²K and reduce noise levels by around 50dB.
This level of performance is reached by using triple-glazed, krypton-filled units and foam-filled sections.Amazingly, it can even achieve extremely low U values using what is considered to be the industry's most cost-effective combination of components; using two 28mm double glazed IGUs (air filled, float glass and aluminium spacer bar) the TwinSash can still achieve an impressive U-value of just 1.2.
Thanks to its enviable level of energy-efficiency, TwinSash is one of the only PVC-U window systems to meet the requirements for Passivhaus.
Mark Barsby, The VEKA UK Group's Head of Technical explains: “The TwinSash system is a very simple concept. It consists of two existing System10 or Rustique sashes joined by a deep outer frame. This means that current Halo fabricators only need to add one additional section. Our customers can extend their product portfolio with only a minimal additional investment, and we anticipate that the TwinSash will be extremely popular with commercial clients. It will also be available to other customers of The VEKA UK Group as a 'bought in' option.
“This system is particularly suited to the hotel industry and the education sector thanks to its sound reduction properties, and also the housing and healthcare sectors with its heat retention and energy-efficiency benefits. It both meets and exceeds the requirements for Level 6 of the Code for Sustainable Homes and is suitable for Passivhaus applications.”
Designed with versatility in mind, the TwinSash can offer a combination of open-in/open-out casements - along with Tilt 'n' Turn windows.
