I feel safe that the insulation is protected from the heat these items give off. Really good by and dead easy to fit. 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. ## Features - Insulation performance – Maximises energy efficiency by preventing heat loss, reducing draughts, and enhancing overall insulation effectiveness — delivering long-term cost savings - Airtight Seal - Designed to create a reliable, airtight barrier around downlights, minimising unwanted air leakage and improving building airtightness - Quality – Manufactured with a high-grade flame retardant polymer and a proven design, ensuring durability, reliability, and user-friendly installation - Quick & Easy Installation – Simple to fit with minimal time, tools, or expertise required, making it convenient for both professionals and self-builders - Robust Construction– Engineered for strength and resilience, offering long-lasting performance even under pressure from insulation and flooring ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B015OA1694 | | Batteries Required? | No | | Batteries included? | No | | Colour | Black | | Customer Reviews | 4.5 4.5 out of 5 stars (646) | | Date First Available | 21 Sept. 2015 | | Item Package Quantity | 10 | | Item Weight | 150 g | | Item model number | TH 001 - 10 | | Manufacturer | Thermahood Ltd | | Material | FR Polymer | | Part Number | TH125-10 | | Product Dimensions | 20.5 x 20.5 x 14 cm; 150 g | | Shape | Circular | | Size | 175mm Inside diameter x 140mm high | ## Images ![Thermahood TH001 - Image 1](https://m.media-amazon.com/images/I/71jEN0Q5TGL.jpg) ## Available Options This product comes in different **Model** options. ## 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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect product *by P***D on 17 January 2026* Just re- insulated my loft and used these for the down lighters and extraction fans.

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 ## Frequently Bought Together - 10 Pack of Thermahood TH 001 - Covers for Downlighter Ceiling Lights and Spotlights - Aids Energy Efficiency - Thermahood - TH 140-10no Pack - Covers for Downlighter Ceiling Lights and Spotlights - Aids Energy Efficiency, Pack of 10 - 12 x Felt Lap Vents, Loft Vents for Condensation, Roof Ventilation Lap Vents, Felt Lap Vents Prevents Loft Roof Condensation, Keep Attic Space Ventilation Airflow --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/49931721-thermahood-th001](https://www.desertcart.in/products/49931721-thermahood-th001) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-06-01*
