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.
