  • 19 Mar 2021

NARM, the National Association of Rooflight Manufacturers, has issued a new document entitled ‘Definition of geometric free area for Smoke Vents’.

Stuart Middle, NARM’s Technical Committee Chairman, commented: “This document is intended to contribute to improving fire safety standards by clarifying the definition of the term ‘geometric free area’ in respect of smoke ventilation, to ensure compliance as defined in Appendix D of Approved Document B2 of the Building Regulations.”

The document is listed as NARM Quickguide 07 and can be downloaded free of charge from the Technical Documents section of the NARM website library.

NARM represents manufacturers and suppliers of all types of rooflights into the UK market, many of which incorporate ventilation functions.

Its purpose is to identify and promote best practice in rooflight specification, installation, maintenance and safety.

The NARM website library hosts an extensive range of technical guidance documents, covering rooflight-related topics from general daylight design guidance, to energy saving, safety and regulatory compliance.
