NARM has published an updated version of its Quickguide 08, entitled ‘Understanding CWCT Classifications of Rooflight Types’. The CWCT (Centre for Window & Cladding Technology) tests for non-fragility comprise of soft body and hard body impact tests as well as a load retention test. They are intended to identify what glass size and type of…
At NARM, our purpose is to identify and promote best practice in rooflight specification, installation, maintenance and safety. A key part of this role is to encourage and support clarity and integrity in manufacturers’ technical data and product promotion. NARM is therefore a strong advocate of The Code for Construction Product Information (CCPI), which we…
As recently as the turn of the millenium, there was still a prevailing perception amongst architectural specifiers and other interested parties, that rooflights had a negative effect on the energy efficiency of buildings. This view was borne out of the fact that even the best insulating rooflights of the time generally offered lower thermal performance…
RIBA has approved a further two NARM Technical Documents for CPD use. NARM NTD11: ‘Understanding the differences between ‘non-fragile’ rooflights and ‘walk-on’rooflights for deliberate foot traffic’, gives detailed definitions of these two distinct categories of rooflight to enable clear understanding and avoid specification errors. NARM NTD12: ‘An introduction to natural daylight design in domestic properties’,…
NARM, the National Association of Rooflight Manufacturers, is an active trade association representing UK rooflight suppliers and associated businesses. We are dedicated to the application of best practice in the provision of natural light in built environments. At the heart of NARM is our influential Technical Committee, comprising leading experts in the design, manufacture and…
Reflecting the continual developments in materials and the design and specification of glass rooflights, we have updated our guidance page on the specification of glass rooflights. Glass is used throughout buildings for its optical clarity, longevity and structural properties; it can offer unobstructed views out of a building, or if specified so, can provide natural…
There seems to be a lot of confusion out in the marketplace on this issue at the moment – with manufacturers making different claims and a general lack of clarity arising from what appear to be misunderstandings about the role and application of CE marks. CE marking is simply the manufacturer’s declaration that the product…
In a recent NARM member company survey, 78% of respondents said their level of business is affected by spurious claims by unscrupulous or misinformed roof light suppliers. Unjustifiable performance claims in terms of thermal performance appear to be the main cause for concern, with some companies making claims which are simply impossible when put under…
