4/4/2018 SpotClip addresses fire safety hazard from down lights installed in insulated cavitiesRead NowLow-energy building standards and energy-oriented modernisation of buildings require increasing amounts of insulation in our home and workplaces. Metric Cable Gland This often poses problems when installing down lights or recessed spots in insulated cavities.
The risk of fire from installations that get too hot is significant. Results of a recent test commissioned by the Electrical Safety Council in the United Kingdom revealed that incorrectly installed down lights such as halogen luminaires covered in thermal insulation are one of the main sources of fires in the modern home (test report available from this page). Without adequate ventilation to permit safe heat dissipation, lamps not specifically designed to be covered by thermal insulation, or installed too close to combustible materials such as roof timbers, can cause fires or harmful thermal effects to their surroundings. A fire rating itself does not imply that a light fitting should be covered with insulation such as glass wool. Particular care must be taken where loose-filled insulation is used, as this can be moved easily by drafts or vermin and may then come into contact with the hot lamp. In this article, Steve Slater – Product Manager for Installer & Connection products – discusses the trend for downlight installation and dispels the myths surrounding LED lighting. In order to permit the dissipation of heat, recessed down lights and their transformers should not be covered by insulation material and need to be protected against potential or future covering. Although Building regulations in many countries do not prohibit leaving small areas free of thermal insulation around recessed lights in order to permit the dissipation of heat, this can have undesired effects on the thermal and acoustic performance of the premises.
