The key to Fireguard is its intumescent material which is uniquely fitted to the luminaire. This material, together with strategically placed holes which allow ventilation, allow the lamp and fitting to run as cool as possible, leading to longevity of the lamp. The intumescent material is an expandable material that is extremely sensitive to very high temperatures. It's used in the most prominent parts of the fitting, such as around the rim, to give the most effective result.
In the event of a fire, the intumescent material will expand 2-3 times its thickness to close up any gaps and seal the ventilation holes, therefore maintaining the integrity of the ceiling for the required 30, 60 and 90 minutes. The use of this material also means that the contractor need not be as accurate when cutting holes as with other products, since it will expand to fill any gaps in the event of a fire.
With its intumescent material and ventilation holes, the luminaire seals from the front, while heat is dispersed from the rear of the can. Additional thermal heat build-up is absorbed by the body of the luminaire.
The ceiling clips on the side of the fitting are made out of spring steel, which retains its integrity and rigidity at high temperatures so there is no danger of the fitting slipping or moving once in place. The unique two-part spring location allows the fitting to be placed into ceiling boards of differing thicknesses, as it can be moved up or down as necessary to fit securely, thus ensuring total fire safety.
