HeatkeeperRadiator Insulation Panels - 20 Pack with free delivery

Arrived very promptly but was not in manufacturer's packaging as shown. I received only 19 panels. As the panels are tightly nested and prone to static I had to count several times to be sure, and ended up separating them and spreading them all over the floor. I called the company who were apologetic and offered to send an extra panel. The panels are quite large and very thin so I appreciated that it would be quite difficult to send just one. Knowing that I would need to cut some of the panels down I suggested that the company cut the panel into as large pieces as possible to make it easier to send in the post. We agreed on this method, but I was told that if I wasn't entirely satisfied on receipt to let them know and they would try and find a different solution. Within 48 hours the panel arrived. It had not been cut, but folded along the pre-marked cut lines. This seems like a good solution. If I need to cut the panel down it will be fine. I don't know yet whether the creases will fall out, but at least if they do I have the option to use it whole or in larger sections. That was good thinking by somebody. My only reason for not giving 5 stars is that the product wasn't in the manufacturer's packaging and one panel short.As far as the product goes, it's a bit fiddly to fix behind the radiators, but seems to be effective once in place. The L shapes of my radiator brackets all face one way, so the spaces behind the radiators are not symmetrical. I haven't done every room yet, but suspect that this will result in needing a disproportionate number of the narrower sections and getting left with some wider sections. Hoping that this won't mean I have to order extra. Bear this in mind when calculating how much you need!

I bought this product in order to reduce my gas bill while trying to increase the heat output of my radiators. The radiator I wanted to test this on was below a window where the window ledge was too low for me to fit the panels without removing the radiator. I didn't mind doing the extra work if it was going to save me money and give me more heat, plus I thought that having a clear wall to work on that the panels would stick more easily.I was WRONG!I put the double-sided tape on every vertical and horizontal edge so as to get the biggest surface area to stick as possible. however, no matter how many times I rubbed the edges to stick them on the wall they would always come unstuck. At this point, I must say that there is an obvious design fault with the panels in that the outer edges are bevelled, probably as a result of how they are pressed out during manufacture.Undeterred, I continued on i the hope that once I got the radiator back on that the heat would encourage the tape to stick to the wall better. Unfortunately that was not the case, they still came unstuck. In the instructions it states that if the wallpaper is embossed then you need to use an impact glue instead of the tape. It's a pity that was not highlighted in the product description, since glue is not supplied, I didn't have any in the house and I'd already removed the radiator before discovering this. You may think that I only have myself to blame, but the wallpaper is not heavily embossed and, in any case, where I had to cut and join panels together to fit, the surface is perfectly smooth, but they still came unstuck when subjected to the heat of the radiator.So, why have I given this product 3 stars? Because the heat output of the radiator has increased. It is too soon to tell if my gas bill will be reduced, but the thermostat is not turned up so high and the room feels much warmer and that, at the end of the day, was the object of buying the panels.I don't know if this exercise would have worked any better had I invested in some impact glue, but it may be worth a try. However, the heat output is good so, if that's all you want and can't afford new efficient radiators, then this is a cheap alternative.

These are quite strong despite their thinness. They are a moulded plastic,coated in some kind of chrome I bought the 20 pack and there were lots left over because they are only really needed on the radiators that are against outside walls. I backed 6 radiators, One large radiator took about 2 and 1 half sheets .The medium ones took 2 and the small ones , one The tape is narrow ,about 1cm wide but there are ample rolls to do the job. We had to use some epoxy on one wall where the tape just wouldn't stick.They are easy to cut with scissors.I like the look of them. On some radiators, we can see them( the stairs radiator ) and they look quite a lot better than the foil on cardboard we had behind there before.If you have radiators directly under a window sill with no gap, and a thick skirting board below, check that you can slide a hand up from the bottom before ordering. They need at least a fingers thickness of space to be able to get them into those awkward narrow gaps.We have a freezing kitchen and the panel in there means we can now tell when the radiator is on!

About a year ago I used a roll of kitchen foil and silver tape to do my dad's radiators, very fiddly to do. By comparison this pack makes it a piece of cake, the precut squares look fab and are easy to cut to size. Double sided tape is nice and sticky and using fingers and a short bamboo cane (put insulating tape on one end) easy to fix in place. They look excellent behind and to the sides of the radiators, very classy. Ace product that does make a difference, as my rooms feel noticeably warmer now.After a few days some of the tape strips came loose, used tweezers to put in small strips of adhesive tape, and smoothed down again, for stubborn spots I used Evostick contact adhesive, the brown smelly glue that really does grip. I think the manufacturer should use stronger adhesive tape, otherwise panels look excellent.Finished off the top and sides with 1" aluminium tape and it looks great now, happy chappy 😀
