Downlight Cover Hoods Fire Rated

Description

The downlight fire hoods are an innovative solution for achieving a safe and easy to install sealing system for downlights.

We have a choice of two downlight fire hoods available:

Their fitting dramatically reduces the volume of air leakage through each downlight, therefore significantly reducing draughts and energy loss. They also ensure the maintenance of an effective moisture barrier:

  • Tested to both BS EN 60598-1 and BS EN 60598-2-2,
  • Flammability & Fire testing to UL94 and IEC 695-2-1,
  • Conforms to BS 5250 : 2011 : 3-3.

Downlight fire hoods, tested to all necessary standards including flammability and heat resistance testing. That allows the housing of recessed lights without disrupting your homes thermal envelope and airtightness barrier. The downlight hood is easily fitted and sealed to an air tight membrane or plasterboard using Gerband 586 airtightness tape or Fortax 6400 airtightness sealant. Downlight or recessed lights are the source of a high proportion of air leakage in the home.

Gaps in ceiling insulation reduce its overall performance. Furthermore – not insulated ceiling (even 5%) usually reduce it by 50%! Finally, the downlight hood restore ceiling performance to similar level as an unpenetrated ceiling. It allows the insulation to be continuous and uninterrupted over the whole area of the ceiling, saving energy, carbon emissions and cost.

Application

 

  • Apply Primer 6300 around hood base which will be bonded to membrane, allow dry.
  • Apply Fortax 6400 sealant to hood base.
  • Fix wires so they are accessible when hoof is fitted, through the hood or under the hood. Ensure any wire penetrations/cut-outs in the hood are sealed with sealant afterwards.
  • Fit the hood onto the membrane and apply extra sealant.
  • Allow sealant to dry before any further work is done around hood.
