Composite windows for your home I
t’s never been more important to save energy in the home, and for self-builders the chance to build
from scratch is the ideal opportunity to specify the best low-energy building products - including windows and doors. With the right windows you can enjoy comfortable, low energy living and the ideal indoor climate, the perfect balance of natural light, effi cient ventilation, peace and quiet and ideal temperature all year round and in every room. VELFAC aluminium / timber windows and doors deliver style and durabil- ity plus great low energy performance thanks to a host of features including: • U-values as low as 0.8W/m2 glazed units
K for triple
• An ultra-slim VELFAC frame (only 54mm) to maximise daylight and improve energy effi ciency, as glass is a better insulator than frame • Low emissivity coatings, plus low conductivity gas between glass panes, to further improve insulation
With VELFAC composite windows enjoy big light-fi lled rooms, no draughts or cold spots, a consistent internal temperature – and reduced energy bills.
THE LONG HOUSE, Oxfordshire ‘The concept of draught free windows which would never need repainting was
very appealing’ Working closely with owners Jan and Diana Thompson, architect Rob Statham of Hayward Smart Architects has created a house which refl ects local architecture while delivering impressive low energy performance and modern design. As part of this, VELFAC triple glazed aluminium / timber windows and doors provide excellent insulation, increase daylight, and emphasise the beauty of surrounding woodland views. The Long House features an ‘upside down’ fl oorplan, with VELFAC windows installed throughout, together with
hinged and bi-parting patio doors. On the fi rst fl oor, large VELFAC units combine to create two impressive glazed screens, one fronting the opening plan kitchen and living space, while the other brings drama and daylight to the master bedroom. The triple glazing supports an impressively consistent internal temperature, all year round, with extended eaves helping mitigate the impact of solar gain. ‘We recommended VELFAC for the Long House because we had used the system in other projects – including our own offi ce - and knew that it was both very neat and high quality,’ says Rob. VELFAC windows and doors met a wide range of performance and design criteria, including excellent U-values and air tightness (important as the house is built to Passivhaus principles) and durability: ‘Jan and Diana were moving from a draughty 17th
century
house with windows which needed regular maintenance,’ says Rob. ‘The concept of draught free windows which would never need repainting was therefore very appealing.’ The uniformity of the VELFAC frame construction, and its slim design, was also important: ‘A slim frame increases the glazed area, in turn improving insulation and daylighting,’ Rob explains. ‘The uniformity of VELFAC sightlines across every window and door, plus details such as hidden hinges,

also delivers a minimalist and coherent fi nish which ties together every element of the build.’
The option to specify different
fi nishes, inside and out, was another advantage: ‘We chose anthracite grey for the external aluminium frames to echo the seamed zinc roof and the veins of the local ironstone used in the front facade,’ says Rob: ‘It also provides a contrast with the white rendered walls and Western Red Cedar cladding. As oak is an important theme throughout the interior, inner VELFAC timber frames are fi nished in a clear lacquer,’ he adds, ‘and the slim, natural wood fi nish also acts as a ‘picture frame’ for the beautiful views beyond.’
