Available in standard sizes, contact our sales team on 0113 245 5450 to order a custom size fire cage.

Intumescent fire cages restore integrity to plasterboard and suspended ceilings, covering and offering fire protection to fittings and downlighters, with the acoustic variation dampening airborne and impact sound, and both types have ventilation to disperse heat so that downlighters don't overheat. This ventilation seals up in a fire, preventing flames and heat from entering roof spaces, such as lofts.

Acoustic cages are useful between floors of residential apartments, especially where businesses and shops are on the ground floor.

Choose from 4 types of fire cage for standard light fittings or for combined light fittings and transformers, with or without acoustic protection. Custom sizes can be made to order.

Envirograf Intumescent Downlighter Adapters are available for converting existing downlighters in low-energy units.

Examples of use

Shops and businesses with residential flats and apartments in the floors above often have lights that buzz and flicker throughout the workday, creating noise for those living above, especially on weekends when people are at home and a business has its busiest trading day.

Plasterboard and suspended ceilings in office blocks and multi-floor apartment buildings often have downlighters in corridors, stairwells and dwellings. Without adequate fire protection these lights reduce the integrity of a ceiling to a matter of minutes.
