How does Radiator Reflector Foil actually work?

The reflective foil is positioned between your radiator and the wall. Its reflective surface helps redirect radiant heat away from the wall and back towards the room, helping you make better use of the heat your radiator is already producing.

Is it difficult to install?

No. Simply measure the space behind your radiator, cut the foil to the required size and position it behind the radiator. The material can be cut with ordinary scissors, so there’s no complicated installation or specialist equipment required.

How much foil do I get?

Each roll measures 60 cm × 10 metres with a thickness of approximately 2.4 mm. You can cut the roll into individual sections based on the dimensions of your radiators.

Can I use it anywhere other than behind radiators?

Yes. The reflective insulation material can also be used for a variety of insulation projects, including lofts, walls, floors, garages, sheds, caravans and other suitable spaces.

Will it reduce my heating bills?

Radiator reflector foil is designed to help reduce heat loss into the wall behind your radiator and reflect more radiant heat towards the room. Actual energy savings will vary depending on your home, insulation, heating system, installation and usage, so we wouldn’t promise a specific reduction in your heating bill.

What Our Customers Are Saying

  • Made the living room feel more comfortable

    I fitted this behind the two radiators in our living room and was surprised by the difference. Easy to cut, easy to position and it feels like less warmth is disappearing straight into the wall

    Sarah M.

  • Simple job with an immediate purpose

    Took me less time than expected to measure and cut everything for our radiators. The foil sits neatly behind them and reflects the heat back towards the room instead of heating the outside wall

    James T.

  • One roll went much further than expected

    I originally bought it for the bedroom radiators but had plenty left for a couple of other rooms. Really straightforward DIY job and you barely notice it once it’s behind the radiator

    Customer Reviews

    • Keeps more warmth in the room

      I fitted this behind the radiators on our outside walls first. Really straightforward to measure and cut, and the rooms feel much more comfortable once the heating has been on.

      Michael Schneider

    • Much easier to fit than expected

      I thought getting it behind the radiators would be awkward, but it was actually a quick little DIY job. Cut each piece to size, fitted it behind, and you can barely see it once it’s done.

      Sabine Keller

    • One roll covered plenty

      Bought this for the living room but there was enough on the roll to do several more radiators around the house. Simple idea, easy to install and no complicated tools needed.
