Description
Fireproof Acoustic Downlighters
Fireproof acoustic downlighters (cover) fit above suspended ceilings in roof areas, or where floorboards are already in place. Offering effective airborne and impact sound absorption, as well as fire integrity for 60 minutes.
With the increased use of downlighters, unfortunately, the integrity of the plasterboard and suspended ceilings can be reduced to 4 minutes of protection. Envirograf® downlighter covers effectively restore the integrity required by the British Standard Regulation requirement.
- Available in many standard sizes, other sizes are available to order
- Easy to install in about five minutes from below or above the ceiling
- With cable entries on top, the intumescent covers ventilate to avoid light fittings overheating
Our electrical and plumbing products meet IET wiring regulations as well as Document B & E of Building Regulations tested to European and British Standards. Browse our full range of electrical and plumbing products.

Advantages
– Maintains the fire rating of plasterboard or suspended ceilings rated up to 4 hours
– Available in standard and acoustic forms, preventing sound transfer from different floors of a building up to 63dB
– Can be made to accommodate downlighters alone, or downlighter/transformer combos
– Downlighter cages are a sturdier option, allowing for insulation to be laid over the top after they are fixed in place – ideal for lofts
– Can be used to improve the fire rating of ceiling-mounted speakers as well as downlighters
– The range also contains downlighter adaptors which can convert existing light fittings to fire resistant, low-energy units, saving up to 40W per light whilst providing 66 minutes of fire protection
– Easily installed in 5 minutes or less. Custom sizes made to order.
Application Instructions
Lead the cable from the transformer through the pre-cut downlight aperture in the ceiling
Pierce the cable entry point in the top of the cover with a sharp object, creating an opening large enough to suit the cable size
Feed sufficient cable through the opening for the connection
Compress the cover and pass it through the aperture in the ceiling
Open out the cover once inside the ceiling, away from the light fitting
Using the two supplied pins, fasten opposite inner flanges of the cover to the plasterboard
Insert the light fitting and fasten the closing mechanism over the inner flaps of the downlighter cover to seal the opening
Downlighter covers require a minimum of 40mm horizontal clearance and 15mm vertical clearance
Cages are rigid and require no clearance, meaning that insulation can be packed around them as long as it does not cover the ventilation holes
NB: Downlighter cages cannot be compressed to fit through the light fitting aperture from below and must therefore be positioned from above
