Window and insulated sash and frame. These advanced window systems both offer big energy savings, as well as providing unparalleled environmentally friendly and other user benefits and features. NorDan’s unique ‘N-Tech’ range provides up to 50 per cent reduction in heat loss from buildings. A traditional, single glazed window has a typical ‘K’ value of around 5.0 W/m2K, whereas NorDan’s N-Tech windows have a ‘K’ value of just 0.7 W/m2K, making them the most efficient, insulated windows in the world. In order to achieve this remarkably low value, NorDan’s in-house R&D department redesigned the thermal surround of the window sash and substituted it with special aluminium spacers and with super-spacers made of silicone. Unlike typical aluminium spacers, which permit heat transfer through the
perimeter of glazed units, this super-spacer provides an extremely effective barrier against heat transfer. The result is that the temperatures at the edges of the glass remain several degrees warmer and in turn greatly reduces the risk of condensation and the subsequent heat loss. Furthermore, to enhance the quality still further NorDan also uses the highest performing coated glass and fills the void in its glazed units with Argon gas in order to ensure minimal heat loss outage.
Supporting the Commonwealth Games The continued demand for NorDan’s products is evidenced in the number of contracts it continues to win. For example, the year (2014) it supplied the timber windows and doors for the Glasgow 2014 Commonwealth Games’ Athletes Village.
The homes in the village were designed to the stricter U-values and air tightness demanded by the 2013 Building Regulations for which NorDan’s timber windows and composite door products were ideal. NorDan supplied high quality high performance tilt and turn timber windows and fully reversible windows from its NTech 1.2 range. External doors were from the NorDan factory at Bor in Sweden, with glazed doors for the ground floors and balconies manufactured at Egersund Norway.
Increasing demand for ‘Passive Window’ insulation When NorDan launched its low-energy windows with Passive Window insulated sash and frames, building companies and architects alike applauded its many attributes.
