## Description

Product Description

Review: Allowed me to insulate the attic - Bought these to allow me to insulate the attic after we had spot lights installed in the bathroom. They’re a great size, bigger than you’d expect (you could wear as a hat!) but the size is essential so the plastic doesn’t come into contact with the light fitting or get too hot. Can easily fit in all of the light fitting, transformers, connectors, wires etc under the hood. Have laid the insulation over the hood, this means there’s a lump where each hood stands but I really don’t see why this would be an issue for anyone. All rooms are now warmer due to the added insulation in the attic and months on I’ve had no issues with them. All of the hoods had fire safety rating/kite marks on them so confident they’re the right tool for the job. Have recommended to friends and colleagues.
Review: A must when insulating attic. - Used these in my attic when adding extra insulation. No more draughts into the attic through spot lights. Glad I discovered them and great value on desertcart.

## Questions & Answers

**Q: Hi, do they need to be glued down or can they just be placed down and then covered by insulation?**
A: I've just placed them down without glue. Felt that the weight of the insulation on top of it would be sufficient to hold them down. I guess using sealant would help to seal around the base, but my only concern would be how resistant the sealant would be to the heat generated if you were using halogen bulbs. My solution was to convert all to LED's which emit less heat.

**Q: I need to fit a couple of these below my attic floor, are they flexible enough that I can squash them down a bit as they are about an inch too tall?**
A: They are manufactured from rigid plastic or similar and not squashable.  Brilliant product though, properly sealed I now get no draughts from my down lighters!

**Q: Can you stick down with no nails?**
A: Thermahood - Downlight Covers can be fixed in place using this adhesive;  https://www.amazon.co.uk/gp/product/B01MSAS5DX/ref=ag_xx_cont_xxB01MSAS5DX

**Q: Can these be used simply to deal with reducing risk of fire? My downlights go straight into the loft and are next to insulation.**
A: Thermahood Downlight Covers have been designed to compartment the light, providing separation between the light fitting and loft insulation, storage items etc.Thermahood Downlight Covers will also help to;Reduce Heat LossReduce DraughtsImprove Air QualityReduce the Risk of Condensation

### ⭐⭐⭐⭐⭐ A must when insulating attic.
*by B***N on 14 January 2026*

Used these in my attic when adding extra insulation. No more draughts into the attic through spot lights. Glad I discovered them and great value on Amazon.

### ⭐⭐⭐⭐ As expected
*by C***Y on 5 November 2024*

They do exactly as described. A solid down flight cover. Something to be aware of is that they are quite large so if putting them in an attic they may not fit perfectly between joists
