Designing with Daylight
Roof lights can offer real benefits in all types of buildings. They can form part of an effective technical lighting scheme, particularly in conjunction with efficiently-controlled artificial lighting, to produce specified illumination levels for particular tasks.
According to leading consultants, horizontal roof lights provide two and a half times more light than vertical windows.

Actual U Values for roof lights should be established in accordance with the BRE publication BR 443 (2006 edition) ‘Conventions for Ud value calculations’ which can be particularly difficult unless independent, accredited testing has been carried out. Xtralite provide technical bulletins providing full information on this important topic.
