Fire defiantand regulations compliant


Mike Collins, sales director with Ovia, looks at the latest challenges facing the fire-rated LED downlights market.


F


or many years the market for fire-rated downlights has been the cause of some confusion, with many


manufacturers making claims but not always having the technical data to back up these claims. The NHBC guidance on the use of fire-rated downlights makes it very clear that only correctly tested products can be used in the type of floor construction in which they are being fitted. With the increasing use of I-joists as part of floor construction – around 70% of new build homes feature engineered timbers joists, as opposed to solid timber joists which dominated the market 20 years ago - the National Housebuilding Council (NHBC) has updated its technical guidance on recessed light fittings in ceilings to intermediate floors in houses. As a result, the NHBC now requires test evidence showing that recessed downlights are suitable for a similar I-joist and plasterboard combination. It was 2005 when the first fire-rated downlight was launched within the electrical contracting sector. The product was the FlameGuard fire- protected and acoustic-rated downlight and the manufacturer was Scolmore Group company, Ovia. Since then, the company has continued to innovate and drive the market by adapting its fire-rated downlights range to meet the changing construction environment and associated legislations. As a result contractors have always been able


to rely on Ovia Lighting to offer a range of products and solutions to help them meet the evolving challenges they face, with the growing FlameGuard and Inceptor downlights ranges. The new guidelines from NHBC on recessed light fittings have provided the industry with its most recent challenge.


ceiling types - solid


timber, I-joists and metal web joists. The company has


recently successfully completed further fire resistance testing to demonstrate that its fire-rated downlights satisfy the new


guidelines issued by the NHBC. The testing


was carried out by Efectis - a major player in fire science, covering all fire safety expertise in


OVIA Inceptor downlight exploded view


Ovia Lighting’s full range of Inceptor and


FlameGuard fire-rated downlights have always been subject to the strictest test measures to ensure they offer full compliance and have the corresponding test certification to meet the very latest regulations. As such, they have all been tested for fire resistance compliance with all


testing and modelling, certification and inspection around the world. The new test consisted of a 30 minute I-joist construction – 220mm I-Joist; 15mm Type A Plasterboard and 22mm Floor Deck (which Ovia believes to be the most common construction types now used within the industry). All fire-rated downlights from the Ovia Inceptor and Flameguard ranges formed part of the test. Today, Ovia offers a fire-rated LED downlight


product to suit virtually every installation requirement. The focus continues to be on developing products that offer the very best in quality and features, represent excellent value for money and are designed to optimise performance, energy savings and safety.


CPD Training To help contractors understand the issues


around testing, Ovia has produced a CPD training module – ‘Downlights and Testing for Fire Rating’, available for delivery on request.
