Product Information

Full details

The Lowenergie Thermahood is designed for homeowners and contractors looking to improve the energy efficiency of their loft spaces by addressing heat loss through recessed downlights. By creating an airtight seal over light fittings, these covers prevent draughts, reduce condensation, and keep loft insulation materials away from hot fixtures. While highly effective at stopping air leakage, they require proper placement and sufficient overhead space in the loft to ensure a secure fit around each fixture.

Extended Product Information

FAQs

Will these covers cause my downlights to overheat?

Thermahood covers are designed to be safe, but you should always use them with appropriate downlights, ideally LEDs, which generate significantly less heat.

Can I use these with all types of downlights?

They are designed for standard recessed downlight fittings; check that your specific fixture width is compatible with the interior dimensions of the cover.

Do I need to fix the covers to the ceiling?

The weight of the cover and the surrounding insulation typically keeps it in place, though it should be positioned carefully.

Does this cover block all air movement?

Yes, when correctly seated, they create an effective barrier against air leakage, moisture, and dust ingress.

Is this product suitable for new build houses?

Yes, they are an excellent choice for new builds to ensure airtightness and meet modern energy efficiency standards.

Troubleshooting

Cover does not sit flush against the ceiling

Check for loose wires or debris underneath the cover that might be preventing a flat fit.

Difficulty sealing around awkwardly placed rafters

Ensure the cover is positioned to accommodate the light fitting; if the space is extremely tight, ensure the unit is pushed as close to the ceiling board as possible.

Pros and Cons

Pros

Reduces energy bills by stopping ceiling air leakage
Improves indoor air quality by blocking insulation dust
Compatible with most standard recessed downlight sizes
Enhances fire safety by isolating heat sources
Easy installation without the need for specialized tools

Cons

Requires access to the loft space for installation
May not fit extremely bulky or non-standard light fittings
Needs careful positioning to ensure a proper airtight seal

Setup, Compatibility & Care

Installation is straightforward and requires no complex equipment. Ensure the power to your lighting circuit is switched off at the mains before beginning work in the loft. Clean the area around the downlight to ensure a flush seal. Place the Thermahood cover centrally over the fitting, ensuring it sits flat against the plasterboard of the ceiling.

For ongoing care, periodically check the covers if you are performing other work in the attic to ensure they haven't been dislodged by movement or maintenance. The covers are maintenance-free but should be inspected for structural integrity if you ever upgrade or replace the underlying light fittings.
