BLOSTM Radiator Insulation Foil Roll

I recently purchased the BLOSTM Foil Insulation Roll, and it has proven to be an outstanding investment for my home. The size is perfect for various applications, including radiator reflector panels, floor, ceiling, roof, and wall insulation. The versatility of this product is truly impressive. I've noticed a considerable reduction in heat loss, which has translated into lower energy bills. The insulation roll is easy to cut and install, making the process straightforward even for someone with minimal DIY experience. The thickness of the foil is just right, providing excellent insulation without being too bulky. However, one thing to note is that the roll does not come with adhesive backing, so you will need to use your own adhesive or tape to secure it in place. Despite this minor inconvenience, the quality of the material is top-notch, and it feels durable and reliable. Overall, the Insulation Roll has exceeded my expectations in terms of performance and ease of use. It's a fantastic product that delivers on its promises and offers great value for money. Highly recommended!

This is a fantastic product. Very light . Top quality and very easy to cut. It reflects the heat from behind the radiator. Saves energy.

Good product Good value for money

I used this BLOSTM foil insulation roll to line the inside of my garden shed, and I’m genuinely impressed with the results. The space went from damp and chilly to noticeably warmer and more usable—especially in colder conditions. Installation was simple. The roll is lightweight and easy to cut to size, and it handled corners and awkward spots without tearing or crumpling. I fixed it in place with a staple gun, and it stayed secure even on uneven wooden panels. The 3-in-1 design really shines here—it reflects heat, adds a thermal barrier, and helps control moisture. Since adding it, the temperature in the shed is far more stable, and there’s less condensation on tools and equipment. At 25m long, there was more than enough material to cover the walls and ceiling of a standard-sized shed. It’s excellent value for what it offers—an easy, cost-effective way to insulate a small outbuilding without needing professional help. If you’re looking to turn your shed into a more functional space year-round—whether for storage, a workshop, or even a garden office—this insulation roll is a smart upgrade.

Easy to fit and really does stop heat being wasted by being absorbed into the wall. The wall behind my radiators is now cool to touch but the radiator is hot, so the heat is being distributed more efficiently. I only wish I'd bought and fitted it sooner. I think a good price too. I would recommend this product.

Recommend this to everyone with radiators . It does increase the area temperature up to one/ two degrees . Easy instructions not noticeable behind the radiators . .

I wanted to help improve the heat retention in a top floor flat and decided to try this silver reflective foil so purchased the 0.6m x 25m roll. As advertised the foil is thin, a few cms in depth and hence very lightweight and easy to cut to size. I wanted to use this behind external wall radiators as well as insulating some cupboards I have which are literally in the eaves of my flat (and hence get quite cold and blowy in the winter months). In terms of installing the foil it is simply a cut to size and stick/adhere to the surface. I found that if the surface was smooth such as wall or wood board I could use a strong double sided tape to bond the foil to the surface. However if the surface is uneven or porous it is better to use some sealant. For my projects I used both and the installation was quick and easy to do. In terms of results it is hard to judge specifically, the radiators do seem to get hot quicker which I guess is the purpose and stops heat or energy wastage on the external wall. The cupboards also seem to be slightly warmer and certainly it stops the wind blowing through the open spaces. So to conclude I am reasonably pleased with the outcome, do not expect night and day difference but it certainly shows slight improvements. Also when using in cupboard space please overhang the foil to ensure a complete seal around the area. I am giving it 4 stars, the 50m length goes far and the results help a little and in today's environment everything that helps to reduce my energy bills is most welcome!

Best value for money ever. I've used this product to go on the wall behind all my radiators and we are already noticing the thermal improvement in all my rooms. I also, used some of the remaining roll to act as draft excluder under the kitchen units sticky taping the underside top and base of the floor - this worked a treat too. One very happy customer :-). Thanks to you all at the company on producing this excellent quality insulation roll.
