New guidance for the specification of non-fragile rooflights

  • 19 Feb 2015

NARM’s new guidance document has been produced to reduce specification errors for non-fragile rooflights

Walk-on rooflights are high specification glass structures designed to floor loadings. They are unsuitable for most rooflighting applications.

Specifiers often refer to walk-on specification, which demonstrates their confusion; their requirement is actually for a non-fragile rooflight.

The National Association of Rooflight Manufacturers (NARM) has published a guide with practical specification advice on non-fragile rooflights.

The document has been published to inform specifiers of the hazards they can cause by using undefined terms such as “man-safe” and “walkable” when referring to rooflight specification.

The documents offers practical recommendations for specification as well as typical load capacities for walk-on rooflights.

NARM also includes general guidance for safety on roofs in its new document.

The document, which is entitled NARM NTD 11– Understanding the differences between “non-fragile” rooflights and “walk-on” rooflights for deliberate foot traffic can be downloaded for free on NARM’s website.
