(20 Pack) Thermahood Loft Insulation Light Fitting Cover, draught dust & insect proofing, fire safety

(20 Pack) Thermahood Loft Insulation Light Fitting Cover, draught dust & insect proofing, fire safety Description

Description

Thermahood covers are used to go over the top of your recessed down light fittings within your loft space.  

• Separate your loft insulation from your light fitting

• Reduce condensation/water vapour passing into your loft space

• Seal your light fittings to reduce air leakage and draughts

• Improve air quality and reduce dust, fibreglass ingress or blown installation

• Reduce noise and insect infiltration

• Reduce fire risk

Thermahood covers keep your loft insulation separated from your light fitting.  This is especially important nowadays with modern LED fittings whose operational life is determined by heat dissipation.  Overheating of LED light fittings will significantly reduce their working life.  If you're light fitting or low voltage transformer is in contact with loft insulation, this will could cause overheating and a fire risk.

The next most important feature of the Thermahood is that they seal your light fittings from the cold ventilated roof space above.  There will be significant heat loss through your light fittings, especially during winter and windy conditions.  This is partly because there will be no insulation directly above your light fitting, but also due to quite significant air leakage and draughts through your light fittings.

Other benefits of the Thermahood are separating the dusty loft space from your living areas. They are especially good at keeping out irritating fibreglass dust and insects, whilst at the same time, can help to provide additional soundproofing from external noise.  Thermahood will also prevent excessive water vapour from creating condensation within your loft space, especially above bathroom areas.

Downlights can reduce the effectiveness of your loft insulation by as much as 30%, owing to the gaps in the insulation around the lights.
