Key Features

Trusted by Millions

One of the factors that give Radflek Radiator Reflectors an edge over other brands is their massive customer base. They are also the recommended radiator reflectors under the Energy Saving Trust Recommended Product scheme in the UK.

Easy Installation

Radflek has made sure that no user finds it challenging to install the radiator reflectors in their apartment. In fact, their installation process is considered revolutionary because it is so easy and hardly takes a few minutes. All you have to do is measure the radiator accurately. You will then have to cut the material according to the measurements and slip a couple of plastic clips to hang them over wall brackets behind the radiator. That’s all the installation this reflector requires. If you don’t want to measure the height of the radiator, you can simply fold the reflector and attach it to the clip.

Radflek Radiators Compared to Traditional Reflectors

Those who are concerned about the performance of their traditional reflectors and want to replace with a new one should trust on Radflek Radiator Reflectors. They are, by far, one of the most cost-effective and energy-efficient radiator reflectors you will ever come across. Compared to the traditional saw tooth or louvre radiator reflector panels that take an enormous amount of time to install, the ones from Radflek has an easier installation process and are more than 23% energy-efficient than these conventional panels.

Radflek Radiator Reflectors InstallationRadflek Radiator Reflectors can reflect almost 95% of the heat from the radiator’s back into your home, thus cutting down the heat loss that usually takes place through the walls. Imagine losing 45% of the heat produced by the radiator! That accounts for an additional several hundred bucks in the electricity bill. But, thanks to Radflek, you can now reuse that energy successfully. With less energy used to heat the rooms, it also results in a smaller carbon footprint.


Radflek has managed to ensure that they use a premium-quality laminated aluminium as the reflective membrane. It comes with a durable coating that preserves the high reflectivity for a minimum of 60 years. Most importantly, it prevents oxidation of aluminium that allows the reflectors to work in full efficiency for longer periods. Almost all the regular reflectors use kitchen foil to prevent oxidation, which is not enough, especially when you need the reflector to work for hours at a stretch. They tend to degrade and tear quickly.

The reason why Radflek reflectors are more effective that kitchen foils is that they are thicker. With the laminated coating, it becomes difficult for the heat to radiate and escape through the walls. The lamination also makes the reflectors stronger than usual. Kitchen foil tends to tarnish and become dull after a few days because of their atmospheric exposure. If you have to replace the foil now and then, the efficiency of the radiator will come down. This doesn’t happen with Radflek Radiator Reflectors.


Radflek tops the chart among its competitors when it comes to effectiveness. It is effective both for small and bigger rooms. If you often saw condensation on the window sills, it means that the previous reflectors were not efficient enough to constrict the heat into the room. When heat escapes, it tends to hit the window sills that would produce drops of water. But, with Radflek Radiator Reflectors, the heat reflects back into the room. This cuts down the need to use the radiator for long hours. Depending on the comfort you need, you can keep the unit switched on for a few minutes and then turn it off. The radiator will prevent the heat from escaping and keep the room nice and warm for the desired time.

Most importantly, you don’t need any professional installer to remove the radiator. If you manage to take accurate measurements of the radiator, it is enough to install the reflector. Ofgem, UK’s energy industry regulator approves Radflek Radiator Reflectors as the most energy-efficient unit in the industry right now. According to their findings, one sheet of Radflek can save up to 8.9 kg carbon dioxide. This results in more than 83 kWh of energy every year. Considering the urgent need to prevent global warming, this is a massive step for homeowners to make sure they are contributing in the correct way.
