How to Make Radiator Reflectors

Stop heating your walls and start heating your home. Installing Low-E behind your radiators will make your rooms warmer and reduce your energy bills. Low-E reflects 97% radiant heat and is Class 1 fire rated so it’s the perfect material for making your own radiator reflectors. Simply follow the steps below to improve the efficiency of your radiators and improve the comfort in your home.

Please take the usual precautions when using scissors or a blade.

When marking the insulation, be sure not to use a sharp pen that could damage the insulation. Check all measurements and markings before making any cuts. If unsure, cut your mats slightly large. You can always cut a little extra off afterwards, but you can’t add extra back on.

Step 1: Measure Up
Measure the height and length of your radiator.

Step 2: Mark out

Roll out the insulation and mark your measurements on the foil with a marker. Using a straight edge, draw a line between your markings.

Step 3: First Cut
Carefully cut the insulation along your lines using scissors or a utility knife.

Step 4: Cut for the Brackets
Measure the distance from one side of the radiator to the first bracket and mark this on your insulation. Then, measure the distance between the brackets and mark the second bracket on the same side. Using your straight edge, mark a line the height of the insulation along the points of the brackets. Measure the distance from the top of your radiator to the top of the brackets and mark this distance at the top end of each of these lines.

Cut along these lines from the bottom of the insulation, stopping at the marks that indicate the top of the brackets. This will allow you to slide the insulation behind the radiator, sitting over the brackets.

Step 5: Apply Adhesive Tape
Cut a strip of double-sided tape the same length as your piece of insulation. Carefully remove the backing paper (leave the front face paper on for now) and stick it to the wall running flush with the top of your radiator. Then, carefully slide your insulation behind the radiator fitting it over the brackets.

“We used Low-E Insulation to insulate outdoor water tanks. We used to lose a lot of water through evaporation in the summer months. It is made a huge difference. We have now insulated of hot water tanks indoors, and we have noticed our energy bills have gone down too. I’d definitely recommend Low-E Insulation.”

Helen B

“We’ve installed Low-E Insulated strip curtains in a number of McDonalds and Burger King restaurants, as well as a number of off-licences and supermarkets chains.

Stephen C

Cornwall, UK

“The car was built in 1958 and I wanted to make sure it survived another 50 years once we had finished refurbishing it. The Low-E was easy to install and more importantly, it was very thin. You’d never know it was there and it seems to have made a big difference."

Dave C

Dublin, Ireland

“I’ve used low e for the past 15 months. I’ve found it to work fantastic is all conditions. I’ve probably got 20 vans with it fitted and I’ve had no complaints from any of my customers about being cold. Some of the vans are used for skiing holidays in places that are -20C and more.”

J Cochran

Genesis, UK

“We used Low-E to line the interior and the engine bay of our NASCAR, its working really well”

Dave P

NASCAR, USA

“We were unsure if Low-E Insulation would work for us so we ran a test. We insulated one van with Low-E and one with the traditional insulation we had been using. Then we brought both vans down to -4*C. The van insulated with Low-E held temperature 4 hours longer than the van without."

Cameron J

“Are Pods are installed along the coast and up in the mountains. We tried using a few different insulation products, but Low-E has been by far the best. We’ve no issues with moisture, corrosion or nesting. There’s no draught in the Pods are they’re easy to heat.”
