Innovative roof windows

The Christchurch firm, Trans-space, Ltd, markets an innovative range of roof windows imported completely made up from Denmark. These fully-opening windows can be fitted into any roof with an angle exceeding 15 degrees. They are available in eight sizes and are supplied with their own flashing kits. Also available is a range of accessory blinds and awnings. Known as Velux (Ve is a Danish abbreviation for ventilation and lux is an abbreviation for light), the windows are the result of extensive world-wide research into roof windows and skylights. Velux windows let natural light and ventilation into a home. Although ideal for all modern buildings, Velux windows have been used successfully in the Christchurch Cranmer Courts redevelopment. Windows can be operated by hand, Or for out-of-reach installations, by rods, cords or electric remote controls. They are economic to install

and, being double glazed, are energy efficient. In an existing building, Velux windows can be very effective in converting an attic into a very attractive living area. Making the best use of available space (such as an attic), may save expensive building extension costs. A transformed attic with high ceiling and exposed beams can be a library, study, bedroom or just extra living space. It could be desirable to fit a house with a steep roof to provide an attic. This is sometimes an ideal solution when land is not available for a traditional building extension. The use of stylish roof windows makes a roof conversion an attractive proposition. The design of Velux windows makes for easy opening and cleaning. A centrally pivoted opening sash allows for maximum ventilation. It also means the windows can be reversed completely for exterior cleaning. Velux flashing kits supplied with the windows are specifically de-

signed to ensure a completely safe and waterproof installation. The windows are made to suit roofs pitched between 15 and 85 degrees. Strict conditions ensure that the best timber is used for Velux windows. All corner sections are bonded by mortise and tenon. Frames and sashes are always laminated and the best wood surfaces are used for visible sections. Philip Elvidge of Trans-space says there is no similar product available in New Zealand. “To produce this type of product a factory needs a very large output,” Mr Elvidge says. “At present, New Zealand is installing about 1000 Velux windows each year and these are manufactured in just two days. Setting up a factory in New Zealand for the local market would hardly be an economic proposition.”

The roof windows were introduced to New Zealand about four years ago. Since then they have been installed in many Christchurch homes and will be used extensively in the new Y.M.C.A. building. Velux windows were also installed in the Havelock North Ski Club building on Mount Ruapehu. This installation, which involved fitting the windows to an exterior wall, proved the suitability of the designs for high altitude buildings. Along with Velux windows, Trans-space produces and supplies a variety of other products for transforming living space. These include “Modernfold” doors (a Trans-space manufactured brand) and “Spacewall” for home and commercial use. All Trans-space products can be demonstrated in the firm’s showroom.
