Downlighter Cover - Installation Guide
The purpose of this document is to give guidance to approved contractors and suppliers who are engaged in the fire stopping of service penetrations in fire rated structures using the Astro DL COVER.
All service holes through floors and compartment walls must be fire stopped to prevent the passage of fire, smoke and hot gases.
Astroflame Intumescent Downlighter Covers
ASTRO DL Cover has been developed to provide maximum fire protection for holes created in ceilings by the introduction of downlights and to allow for maximum ease of fitting.
In a fire the downlight 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 provides insulation protection to the ceiling void to reduce the chance of heat build up and ignition of flammable materials such as accumulated dust and loft insulation.
Please note: No part of the fitting should touch the inside of the downlighter cover when the cover is centrally located above the cut hole. If contact is made then a large cover is required.
Astroflame intumescent downlighter covers are manufactured in the EU, meeting the highest quality standard in compliance with ISO EN 9001:2000 . For fire test certification contact Astroflame Fireseals technical department.
