For more than 70 years VELUX has led the world in the development of energy-efficient roof windows of the highest quality and durability.
High quality is assured with VELUX, the familiar brand name that is synonymous with roof windows. Our Celsius solid roof system is designed to incorporate standard-sized VELUX roof windows finished externally in discreet Anthracite Grey, with an internal finish choice of standard White Polyurethane (perfect for modern interiors and white ceilings) or optional Natural Pine (ideal for traditional interiors) which is protected with triple-coat clear lacquer to preserve the timber of the window.
VELUX roof window help to maximise the quantity and quality of natural light and ventilation:
• Roof windows provide twice as much daylight as vertical windows and up to three times more daylight than dormer windows (source: Daylight study, Danish Building and Urban Research, 2003).
• As they are angled more directly to the sun, VELUX roof windows (minimum roof pitch 15°) provide direct light with less risk of overshadowing from adjacent buildings.
• Additional ventilation and light can be delivered deep into extensions, to keep the interior spaces bright and airy.
