Tenmat FF109 Fire & Acoustic Downlight Covers are designed to limit the spread of fire and smoke through a fire resistant ceiling/floor system where recessed downlights, spotlights or luminaires are installed.

The FF109 Acoustic Downlight Covers are a product type that may alternatively be known as Downlight Fire Hoods or Intumescent Fire Hoods and are manufactured with ease of installation in mind an ability to be retrofitted into position providing effective performance even if the downlight is removed and replaced. The intumescent downlight covers are ventilated to allow heat to disperse from the light but in the event of a fire, the intumescent material expands to seal off the ceiling cut-out and vent holes, providing effective fire resistance, for integrity (E) and insulation (I) for 30, 60 or 120 (EI 30/60/120) depending upon the ceiling and floor joist construction, even if the downlight is removed and replaced.

Due to the fully intumescent nature of the product, they offer superior insulative protection in a fire situation than other types of fire hoods for downlights.

Tenmat’s Downlight Fire Hoods are manufactured from halogen free intumescent material and are designed to reinstate the fire and acoustic performance of ceilings and/or floor constructions when penetrated by downlighters or blank openings if lights are removed for maintenance. The fire hoods for downlights are made from an intumescent flexible mineral wool material allowing it to be installed through the hole cut into the ceiling membrane, before springing back into shape to cover the light fitting, whilst allowing enough space between the hood and the light fitting to allow for normal operation of the light fitting.
