Downlighters in ceilings are widely used in commercial buildings. Each ceiling is subject to fire regulations and where applicable the ceiling construction needs to be fire rated.However, once a hole has been made in the ceiling for a downlighter, the integrity of the construction and it’s ability to perform in a fire can be reduced significantly. To combat this the ASTRO Downlighter Cover has been developed to cover maximum protection for holes created by the introduction of a downlighter and to allow for maximum ease of fitting. In a fire situation the cover expands internally to fill all the available space with a highly insulating fire resistant char. Thus, the fire is unable to penetrate the hole and the cover is able to give additional insulation protection to the ceiling void to reduce the chance of heat build up and ignition of flammable materials such as accumulated dust and insulation.- Covers a wide range of mains & low voltage downlighters- Acoustic Rated BS EN 1SO 140 : BS EN ISO 717- Ventilated to reduce heat build up- Lightweight & flexible cover can be fitted from below or above the ceiling- Installed in seconds- Prevents fire from penetrating the ceiling void and retains ceiling’s fire protection integrity
