verry good
you get plenty enugth to cover all radiators in your house and you notice a diffrance in tempriture straight away to hold it to the walls i used aliminuam foil tape to hold it in place as the Adhesive Pads dont stick is easy to use and easy to fit as you just cut to size with scissors reflects heat verry well and is good for insulation

Easy to install
Have had this behind my radiators that are on outside walls for three weeks and think it is making a difference. Heating seems to be on less during cold spell, plus 'smallest room' which is part of porch projection on front of house, so three external walls, is definitely warmer. A reduced heating bill would be nice so shall see what next reading brings. Pack was sufficient for three typical sized bedroom radiators, three average living room radiators and one small toilet radiator. Easy to install, cut to size then cut slot up from bottom to allow to slide down over radiator brackets. Did not need adhesive pads supplied.

Fantastic product
This product is an inexpensive way to keep your home warmer in winter for longer. Very easy to cut to size and place behind the radiators it also came with double sided stickers to attach to the wall. I would recommend this product and fast delivery.

Amazing product
I was sceptical but decided to order BLOSTM Radiator Insulation Foil anyway. It arrived the following day and within 20 minutes I had fitted to the back of 7 radiators. The sticky pads were included and worked really well. So easy to fit and has made a huge difference to the heat in each room. I’m sure it will have an impact on my heating bill in the future. I’m very impressed and would highly recommend.

Good quality product
The product is good quality, thick, easy to use, does the job of reflecting heat very well - that's if it would stay in place! The adhesive double sided sticky pads are not very good ! Will not keep product in place. I started with three sticky pads, now there are several - but it still becomes unstuck and slips down. Given up trying to stick it up. It is still behind radiator, but not stuck to wall.

Easy to use but not suitable for cooling rooms.
I got this to cool a hot room. the product is basically reflective bubble wrap in strips. comes with helpful double sided sticky square tabs to stick it to the window. double sided tape also works. easy enough to fit and cut to size. however I found it made the room even hotter than without. the only idea I have is that the air bubbles help to trap heat in the room and the reflective surface stops it escaping. it would be great for radiators. I really think to cool your room you need one way glass or film, to stop heat coming in but to let heat go out. Will be binning but worth a shot. also would be great in winter to keep warmth in. good quality product anyway just not suitable for my intended use

Insulated an outside cat shelter with it.
Used this to insulate an outside cat shelter I'd made for a stray cat that sleeps in my garden at night. I didn't want to use glue because of the smell, thought it would put the cat off from actually sleeping in it. So I used doubled sided sticky tape, I was a little unsure if it would actually work, with it going to be outside in all the elements etc, the box I used is waterproof, but obviously I had to cut a hole in it for the entrance. It has now been about 8wks since I used the insulation, and putting the box outside. The cat must approve as she uses the box every night now, and the insulation has stayed in place!! It hasn't come away from the walls at all, and it is like a cosy little oven inside there....Success! I found the insulation roll very easy to work with, flexible and I doubled it for the job I needed(used a triple layer of it for the base), and it has work brilliantly. Highly recommended by myself and Sabastion the cat....who I thought was a Tom cat....but actually turns out that he is a she....who now only answers to Sabastion....

The product looks exactly like the picture on this site. Easy to cut, flexible to post on the wall behind the radiator. I feel like the warm is reflected in the room since my left leg- near the radiator becomes warmer when the heat is pumped. Plenty enough to use in 5-6 radiators with lenghts 80--90 cm. Once received I placed and there is no mould in between the wall and the insulation film during this time. Recommend!

Jestem zadowolony z zakupu. Radiator można przyciąć do porządanej wielkości. W zestawie są pianki samoprzylepne w kształcie kwadracików aby przytwierdzić radiator do ściany. Polecam.
