Downlighters in ceilings are widely used in public and commercial buildings. The ceilings are subject to fire regulations and, most will have to be fire rated.

However, once a hole is made in the ceiling for a downlighter, the integrity of the construction and its ability to perform in a fire can be reduced significantly.


To combat this TENMAT, as part of its continuing development of passive fire protection solutions, has developed a downlighter fire protection cover.

The cover has been developed to provide maximum protection for holes created by the introduction of small/medium sized downlighters and to allow for maximum ease of fitting. In a fire situation, the cover expands internally to fill all the available space


with a fire resistant highly insulating char. The fire is unable to penetrate the hole and the cover is able to give additional insulation protection to the ceiling void by reducing the chance of heat build up and the ignition of flammables, such as accumulated dust and insulation. The penetration in the ceiling also provides a path for air, thus creating drafts, the fitting of a FF109 cover reduces this problem.
