Description
Recessed downlights are a common feature in many homes, however they also represent a potential fire hazard, especially if buried in loft insulation. Numerous house fires have been caused by the ignition of combustibles in ceiling spaces caused by hot downlights being covered with insulation.
In addition, the thermal performance of a ceiling is typically reduced by 50% when penetrated by multiple downlights due to heat loss through the gaps made in the insulation. Using an Astro Loft Cone restores the air tightness of the ceiling and ensures continuity of insulation so that the overall performance is similar to that of a ceiling without downlights.
The Astro Loft Cone meets the latest needs of BS EN 60598 and other international standards for a lighting product when covered with insulation. It adheres to the maximum external temperatures requested by the IEC even when cool beam lamps are used.
Suitable for aluminum and dichroic reflector lamps up to a max. 50W with cut-out dimensions of 50-100mm.
Designed to meet both the new NHBC requirement for a vapour seal and the requirement for continuous loft insulation documented in Approved Document L, whilst still maintaining an air space between the light fitting and the insulation - as stipulated by many light fitting manufacturers.
The difference in a downlight with and without a Astro LC Loft Cone can be seen via thermal image photography below, in particular see how the excessive heat of a downlight could be a possible point of ignition.
