NARM document on roof window installation on pitched roofs

NARM, the National Association of Rooflight Manufacturers, has published a new technical guide covering the installation of roof windows on pitched roofs.

This comes as part of its ongoing commitment to support best practice in the design and installation of rooflights.

NARM Technical Document NTD16 Roof window installation considerations for pitched roofs, has been produced by NARM member companies to help promote awareness of the typical installation and detailing pitfalls that roof window installers need to be aware of before beginning an installation.

Most detailing for roof windows is not product specific and the info contained in this helpful document can be applied to many roof window installations.

The comprehensive document contains detailed drawings with explanatory notes, for quick and easy access to a comprehensive range of topics including:

• sizing of structural openings
• coursing
• underlays
• levelling and squareness flashings
• insulation and vapour barriers

The new document NTD16 is a valuable resource for roofers and other construction professionals- it can be downloaded free of charge via the NARM website
