Downlight Cover Hoods Fire Rated

Description

Downlight fire hoods in ceilings are widely used in commercial buildings.

Each ceiling is subject to re 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 PHS 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 re 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.

  • Downlight Fire Hoods fire rated to BS EN 1365-2:2000 / BS476 Part 23:1987,

  • 60-minute fire rating,

  • Covers a wide range of mains & low voltage downlighters,

  • Provides a highly insulating stable char when exposed to fire,

  • Prevents fire from penetrating the ceiling void and retains ceiling’s fire protection integrity,

  • Acoustic Rated BS EN 1SO 140: BS EN ISO 717,

  • Ventilated to reduce heat build up,

  • Installed in seconds,

  • No screws, drilling or additional supported required,

  • Maintenance free,

  • Can be used in suspended, plasterboard or concrete ceilings,

  • Lightweight & flexible cover can be fitted from below or above the ceiling,

  • Downlighter can be fitted as normal.

Application

 

  • Prior to fitting, ensure that electrical wiring and components meet and are fitted to current standards, e.g; BS 7671 and/or IEC 60364. Check that all components are suitable to be covered and/or enclosed.
  • Turn off power at the meter, before working with electrical equipment. Clear the area around the downlight and clean any dust or dirt from the ceiling lining (plasterboard / air-tight membrane).
  • Apply a suitable primer around cone base (if required) which will be bonded to the substrate, allow dry.
  • Apply an intumescent sealant to the cone base.
  • Feed wires through the top of the cone and seal with sealant.
  • Fit the cone onto the substrate.
  • Allow sealant to dry before any further work is done around the cone.
  • Fit insulation where desired, including against and on top loft cone.
