Product Description

Product Description

Radflek is the most efficient radiator reflector recommended under the UK’s Energy Saving Trust Recommended Product scheme and is revolutionary in its ease of installation. Radflek is one of the easiest and most cost effective methods of energy saving in the home - at least 23% more efficient than louvered or saw toothed radiator reflector panels and quicker and easier to install. Radflek reflects back into the room 95% of the energy radiated from the back of the radiator and cuts heat loss through the wall and into the outside world by 45%. This means that less energy is used to heat the room to the desired temperature, resulting in lower energy bills and a smaller carbon footprint. Radflek will typically pay for itself in under a year. Radflek is a laminated aluminium reflective membrane with a long lasting coating that prevents oxidation and preserves its high reflectivity for at least 60 years. This is unlike kitchen foil that tears easily and degrades very quickly. There is no need for removal of radiators, professional installers, or any sticking to the wall – Radflek is cut to size with normal kitchen scissors and just hangs from the wall brackets behind the radiator, so disappearing from view once installed. Installation is quick and simple, only taking minutes. Radflek is also the most efficient radiator reflector approved by Ofgem (The UK’s energy industry regulator) for its Carbon Emissions Reduction Target scheme (CERT). A sheet of Radflek will save an average of 8.9 kg CO2 and up to 83 kWh of energy per year. Each sheet of Radflek is 120cm x 60cm and sufficient for 2 typical sized radiators each measuring 60cm between the wall brackets. Pack sizes act as a guide only and are on the basis of such a typical radiator. All packs contain Radflek sheets, clips and instructions - everything required for a standard installation of Radflek (behind a typical wall mounted radiator). Where the distance between the radiator wall brackets is greater than 120cm, Radstik reflective adhesive tape can be used to increase the size of a Radflek sheet. Radstik can also be used to combine off cuts. For floor mounted or where brackets are far from the top and/or the edge of the radiator, we recommend alternative installation methods set out in the 'easy fitting' section of www.radflek.com You should measure your radiators prior to purchase to ensure you buy the correct pack size.

Product Description

Pack contains 5 sheets of Radflek (600mm x 1200mm) and 20 fixing clips.

4.0 out of 5 stars Manage your expectations 29 Jan 2012
Verified Purchase
I did a little research and read plenty of reviews on here before purchasing this item, I was amazed at how daft some of the reviews were and just how crazy some people's expectations are.

I purchased the 10 radiator pack (5 Sheets) and this was enough to cover 4 decent sized radiators in my flat with one whole Radflek sheet to spare. The key point here is to always buy a larger pack than you think you will need, check the sheet size against the size of your radiators. Unless you have really small radiators, there is no way this 10 radiator pack will cover 10 radiators!

I purchased this item from Radflek themselves, via Amazon of course! Delivery was super fast and the item fits through a standard letter box which was handy.

Lets get a few things straight:

1. It will NOT dramatically reduce your gas/electricity bill.
2. It will NOT magically turn your already cold house into the tropics.
3. It WILL reduce your gas/electricity bill just enough to validate your relatively inexpensive purchase.
4. It WILL help warm your house up quicker.
5. It WILL keep your radiators at temperature for longer, therefore reducing the work your boiler has to do.


Some people have said that because the sheets are folded, the folds are hard to get out. Nonsense! Place the sheet on a soft surface and run your finger over the folds, turn the sheet over and repeat, job done! One reviewer here has thought about ironing the sheet to get it flat and another has considered an industrial pressing machine, you cannot be serious!

There are 2 ways you can install the radiator reflectors depending on your preference between cosmetic appearance or maximum radiator coverage.

5.0 out of 5 stars really makes a big difference 24 Nov 2010
By oslet
went to a diy store and landed up with some foam stuff that needed to be stuck onto the wall. it obviously wasnt going to work so looked it up online and reviews said radflek worked. It does! The difference was so amazing, cant think what I was doing heating up my neighbors house. Now my house is warm for a change and all we had to do was cut the foil with scissors and fit on the brackets. Super easy.

4.0 out of 5 stars Very good for modern radiators 25 Oct 2010
Verified Purchase
It's easy to install providing your radiators have the mounting brackets near the top; we have radiators ranging from the 1970s to 2 years old - it requires a little more ingenuity (or hooks) to fit behind older radiators.

5.0 out of 5 stars Heat retention 29 Jan 2011
I ordered this product without a lot of conviction. In the past I have fitted heat relectors made of foam covered in a foil and not noticed any difference. Radflek does what it says, within a couple of days I had turned out heating thermostat down a degree and the boiler was working a lot less. The House was much warmer. I would honestly recomend this product to anyone.

5.0 out of 5 stars Amazing product, amazing difference. 22 Dec 2010
I encourage everyone to buy these. They are incredibly easy to fit (20 mins for 5 radiators)and the difference they make can be felt almost immediately. We have a Victorian house with cavity walls, the freezing weather meant that even with our heating on full blast, the house was still cold. Within minutes of fitting all of them my husband turned down the heating and took off a jumper and then I turned down the heating to its lowest setting and the house was still warm - amazing.I'm sure they'll pay for themselves in a few weeks if this weather continues.

5.0 out of 5 stars Radflek - Radiator Refector panels- 10 pack 19 Dec 2010
Bought these last week and fitted them yesterday.
Even though we have snow on the ground we had to turn the radiators down to low within minutes of fitting them.
They are really throwing out heat now.
Great product and worth buying for the cold snap ahead.
Simple, quick & easy to fit, and work straight away.
Very money/energy saving for such a little effort.
I would reccommend anyone with radiators to buy them now!

4.0 out of 5 stars Radflek reflectors 25 Oct 2010
By D. Rees
Reflector panels were easy to cut to size and to fit, though fitting on long radiators was not very sturdy due to supports being short. Product would benefit from longer supports which could be cut to length.

5.0 out of 5 stars Radflek Amazing Product Highly Recommended 26 Sep 2011
Ordered the Radflex and as always with Amazon it arrived quickly, I had seen the product demonstrated on one of the shopping channels so had a good idea of how it worked, but the p and p was lower with Amazon, so decided to go ahead and order it, also I read a number of reviews, in various places on the internet.
I have 8 radiators and used this on all of them, it took me about 30 minutes to do them all, that night was a chilly evening so thought I would put the central heating on to take the chill off the air.
Within 10 minutes I had to go and turn down the thermostats on the radiators and then I had to turn down the thermostat for the heating on the boiler, and was amazed at how much heat was being thrown back off the radiators into the room, and when I turned the heating off the house stayed warmer for longer.
The product is very easy to fit, and is not visible at all when looking at the radiators.
Although the weather is not really cold yet, the fact that the heat reflected back was quickly noticeable, when the weather does get colder, the thermostats will not have to be turned up as high as they would be without Radflek fitted.
Please do not think this is a fancy tinfoil, the product is very different a real space age design and is actually a thick membrane, and very strong as well, and will last for many years.
I am very happy to give this product 5 stars, any product that can save money with rising energy bills, and lessen greenhouse gasses is really worth using.
