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.
