Are you Installing Downlights in a 30-Minute Fire Rated Ceiling?


Did you know that there is new NHBC Guidance on recessed light fittings?

When installing downlights in houses and dwellings, special attention needs to be given to the critical fire protection of these downlights as they represent an open path for the passage of fire and smoke.

Recent changes in the construction methods from solid timber joists to light weight joists, which are much more fragile when exposed to fire, have made the fire protection of modern ceiling constructions much more critical to avoid premature collapse and vertical fire spread.

The correct fire testing of downlight products is a complex, expensive and lengthy process therefore it can be often “mis-understood” within the lighting industry.

The latest NHBC guidance requires testing on each joist type to reflect the actual construction in which the product is being used, especially as regards to joist type for 30-minute ceilings this is most likely to be either metal web joists or I-beam joists. Tenmat Downlight Covers or fire hoods will provide an affordable and easy to fit solution.

Tenmat prides itself on their fire testing and safety record. Tenmat FF109 Downlight Covers are a full range of intumescent downlight covers available in a selection of sizes, fully tested within metal web joists, I-beam and solid timber joist systems.
