Issues being addressed by NARM include compliance with Criterion 2 of the Building Regulations Approved Document L2A, which requires rooflights to have a U-value of 2.2W/m2K; as well as imported GRP lights which do not carry UK fire ratings.
NARM’s website contains specific guidance on all aspects of rooflight compliance, links to the latest Approved Documents, Building Regulation publications and specification information.
