Improve heat retention by fitting a Thermahood airtight downlight cover
Efficient heating, insulation and airtightness are essential for every home looking to reduce energy consumption and costs.
Thermahood is designed to meet this growing demand by providing a simple and easy to fit downlight cover that forms an airtight seal around the downlight fitting, dramatically reducing air leakage and heat loss. The result is a warm, airtight home with significantly lower energy costs.
Available in a choice of shapes and sizes to suit flat lofts and sloped attic roofs, Thermahood downlight covers are the preferred choice for house builders, electrical contractors and insulation specialists across the UK and Ireland.
Thermahood will qualify for the New Green Homes Grant Scheme as part of any home or loft insulation improvement.

Downlights are a popular choice of lighting that add ambiance and character to our homes and offices. However, often lights are installed without any consideration being given to the effect they will have on heat loss and energy costs, beyond the electricity cost itself.
Downlights fitted in an attic or loft ceiling will create a gap between the light fitting and plasterboard that allows warms air to escape and cold air to enter the room below. This results in a reduction in effectiveness of your loft insulation by as much as 30%. Thermahood’s unique design forms an airtight seal around this gap and protects the performance of your loft insulation by reducing air leakage…. and your energy bills!
Prevents air leakage and heat loss
Thermahood downlight covers provides an air tight seal around downlights in lofts and attics, plugging gaps that cause heat loss and dramatically increasing the airtightness of your home. Our unique design avoids downlights being in direct contact with loft insulation by providing a protective cover over which loft insulation can be safely laid.
Thermahood has been tested in compliance with Building Control Doc. F ‘Conservation of Fuel and Power’ and BS EN 1026: 2000 Window and Doors – Air permeability – test methods.
Thermahood reduced air leakage at 50pa from 5.97 (m3/h*m2) to 4.69 (m3/h*m2), an air-leakage reduction of 21.45%.
Minimises fire risk by isolating downlights
Thermahood is manufactured from recyclable, flame retardant material. Fire risk is minimised by Thermahood isolating downlights from potential contact with combustible household storage items being placed on top.
Thermahood also reduces the risk of downlights overheating by creating a space around the downlight for any build-up of heat to dissipate.
Protects against condensation and timber rot
Thermahood helps minimise the risk of condensation by reducing draughts and air flow between your attic and the room below. This protects against water vapour transmission into cold attic voids forming condensation and long-term problems with rotting timber or roof damage.
Thermahood works in tandem with heat recovery systems to support controlled air flow.
Improves breathable air quality
Thermahood enhances breathable air quality by reducing the risk of dust contamination and associated health issues.
Thermahood was subjected to a test of ingress duct and was deemed to comply with the requirements for dust tight luminaires, i.e. ingress protection classification IP6X.
Blocks unwanted noise, pests, dust and dirt
Thermahood prevents spiders, insects, dust and dirt from escaping through downlight fittings to enter your living or working space. It also reduces the risk of heat emission from your downlights attracting rodents from nesting in your attic or loft.
In contrast to simple fire hoods, Thermahood provides a substantial noise barrier by preventing sound entering and escaping through downlights.
Meets UK and Ireland Building Regulations
Thermahood meets the requirements for Building Regulations 2.3:
L1 fuel conservation
E1 sound protection
Thermahood also helps conform to BS 5250: 2011:3-3; BS EN 50698-1; BS EN 60598-2-2.
Quick and easy to Install
Thermahood is simple to install with or after your loft insulation and can be fitted by a DIY enthusiast, builder, electrical contractor or insulation fitter.
