What is Radflek?

Radflek is a revolutionary energy saving radiator reflector that reflects 95% of the wasted heat energy radiated from the rear of a radiator back into your room

Radflek is a laminated aluminium foil with a long lasting coating that prevents oxidation and preserves its high reflectivity. With Radflek, less energy is needed to heat the room to your desired temperature and so your energy bills will be less. Radflek is at least 23% more efficient than any saw-toothed reflector and will pay for itself in about a year

No need for removal of radiators, professional installers, or any sticking to the wall – Radflek just hangs from the wall brackets behind the radiator. Disappears from view once installed. Installation is quick and simple, only taking minutes- anyone can do it!

How does it work?

Both windows have radiators on the wall below them. The right-hand window's radiator is fitted with Radflek, which has reduced heat loss through the wall by 45%. This can be seen by the more muted colour below that window compared with below the left-hand window

Verified performance

  • Tested by the British Board of Agrément (BBA) and verified by the Building Research Establishment (BRE)
  • Approved by Ofgem for use in the Carbon Emissions Reduction Target scheme (CERT)
  • Energy Saving Trust Listed Product status

It takes no energy to save energy!

  • Radflek only takes minutes to fit
  • No sticking to the wall
  • No radiator removal
  • No DIY know-how needed
  • No major maintenance required - just occasional dusting to maintain best reflectivity
  • Radflek is designed to hang behind radiators, so that there is a small air gap either side of the Radflek sheet
  • Full instructions for installation of either wall mounted or floor mounted radiators installation can be downloaded below
  • For low mounted radiator brackets, close together radiator brackets, floor mounted radiators, curved radiators or extra-long radiators please refer to our questions? for installation solutions

Don't heat the street

Tests carried out by the BBA and verified by the BRE, show that Radflek reduces heat transfer through walls by 45%, is the most efficient radiator reflector on the market, and is 23%* more efficient at saving energy and reducing CO2 emissions than any other type of radiator reflector

Carbon and energy savings will depend on fuel type, wall type and how often the heating is switched on. With a solid uninsulated wall using a normal heating cycle, a 8 sheet pack of Radflek will annually save:

  • up to 71 kg CO2
  • up to £40** Payback in about a year
  • A sheet of Radflek will save 8.9 kg CO2 per year or up to 83 kWh of energy per year
  • Saw toothed reflectors* of the equivalent size will save only 7.2kg CO2 per year
  • * Information on competitors provided by Ofgem
  • ** Based on a British Gas Tariff Comparison Rate (TCR) of 5.71 per kWh (Sept’ 2014)

Customer Case Study

Roy and Chris Wildgoose are Radflek customers from Harlech, North Wales. They say: "The Radflek packs came quickly in the post and had simple instructions with a cutting guide on the sheets, making the whole fitting process extremely easy– just exactly what it said on the pack. It took about 20 minutes to do all nine radiators in our house."

Roy and Chris noticed the difference Radflek made straight away. "We turned the thermostat down two degrees and now only need to have the heating on for an hour in the morning and evening because the radiators are holding the heat for that much longer."
