Loft Downlight Covers
The essential protection for downlights buried in insulation.
Loft downlight covers
Reduce the fire risk of buried downlights
A loft downlight cover, also called a loft cap or loft lid, sits over a recessed downlight in the loft so insulation can be laid right over it without touching the fitting. At the recommended 300mm or more of loft insulation, a downlight can be buried completely, so a cover is needed wherever that happens. Unlike a downlight fire hood, which reinstates the fire and acoustic performance of a ceiling, a loft cover isn’t designed to maintain a fire compartment line. Its job is to keep the light and insulation apart, let the lamp run at a safe temperature and stop warm air escaping around the fitting.
Tenmat Loft Downlight Covers are a fire safety product. They give a fire-safe physical barrier between the recessed downlight and the loft insulation, reducing the risk of fire when downlights are buried.
Loft downlight covers
Design and testing
The fully enclosed design, which is heat build-up tested (formally referred to as F-capped rated) to EN 60598 and IP6X Dust/Particle tight ensures that even the hottest 50W halogen lamps as well as LED lamps can function at safe working temperatures and will not overheat when the buried under insulation.
With energy saving being more important than ever, increasing the thickness of loft/attic insulation is one of the most simple and cost-effective measures to improve the energy efficiency of homes.
Insulation thicknesses are recommended to be at least 300mm and this can result in recessed downlights becoming completely buried. It is no longer acceptable to install insulation without ensuring downlights are protected due to a significant risk of reduced lamp life, malfunction or in the worst case a roof fire.
Loft downlight covers
Why they are essential?
Similarly, it is clear that the old practice of leaving a gap around an unprotected downlight is an open path for heated or conditioned air to be lost into the roof space and energy saving and air tightness to be compromised. Therefore, the addition of loft lid downlight covers is essential.
The Tenmat Loft Lid Downlight Covers are specifically designed to ensure a fire-safe installation for a wide range of recessed downlights and enable loose or rolled insulation to be installed safely over the position of downlights. Tenmat Loft Lid Downlight Covers solve all of the above issues with a simple-to-install product.
Note: Tenmat FF120-RF Loft Covers are specifically designed for the requirements of the French market to meet CSTB CPT 3693 and the NF DTU 45.11 P1-2:2020 requirements.

Loft downlight cover FAQs
A loft downlight cover, also known as a loft cap or loft lid, is an enclosed cover that sits over a recessed downlight in the loft. It keeps insulation off the fitting so insulation can be laid right over the light, while the lamp still runs at a safe temperature. Tenmat’s FF120 and FF130 loft covers are tested for heat build-up and are IP6X dust tight.
Yes. Tenmat loft covers are designed to be fully covered, so loose-fill, blown or rolled insulation can be laid straight over them. That matters because loft insulation should be at least 300mm deep, enough to bury a downlight completely. Without a cover, installers have to leave a gap around each light, which lets warm air escape into the roof space.
If the downlight will be buried in insulation, yes. Tenmat loft covers suit LED lamps and halogen lamps up to 50W, and are tested to BS EN 60598 for heat build-up. Keeping insulation off the fitting helps LED lamps keep their light output and lamp life, and avoids the malfunction and fire risk of a lamp buried in insulation.
A downlight fire hood is an intumescent cover that reinstates the fire and acoustic performance of a fire-rated ceiling where a downlight is fitted. A loft cover does a different job: it sits over the light in the loft to keep insulation off the fitting and stop heat building up. Loft covers aren’t designed to maintain a fire compartment line, so use a fire hood wherever the ceiling has a fire rating.
