The National Association of Rooflight Manufacturers An introduction The National Association of Rooflight Manufacturers represents a complete cross section of the rooflight design and material type manufacturers in the UK. This includes: in-plane profiled rooflights, continuous barrel vaults, modular domes and pyramids, panel glazing systems and architectural glazing systems for skylights, lantern lights and atria. The association has been formed to promote co-operation between member companies, in order to develop and maintain standards and codes of practice – and to provide an authoritative information portal for rooflight specifiers. Why you should ensure your rooflight supplier is a NARM member.
