A new numbering system and design update has been introduced for NARM Technical documents, to allow specifiers to access and reference information more easily.
NARM’s membership covers all currently available rooflight technologies and the organisation is committed to providing a reliable source of objective and up-to-date information for specifiers, through its Technical Documents.
These cover a variety of subjects from general guidance on designing with daylight to specifics including thermal performance, non-fragility, integration with artificial lighting and other issues facing specifiers.
