Maximise Your Radiators Performance

The EcoTec Radiator Insulation Kit is a fast and cost effective way of maximising the performance of your radiators, within your home.

Did you know around 40% of energy from radiators can be lost via the walls? This is why it is absolutely vital to insulate behind them. Insulating your Radiators means that you can literally heat your home for Less Money!

The EcoTec Radiator Kit consists of a True Aluminium Foil either side of an air bubble membrane, this True Aluminium Foil reflects over 95% of radiant energy back into your home!

What does the Radiator Insulation Kit Include?

The EcoTec Radiator Insulation Kit comes on a 400mm x 15m multifoil insulation roll, which provides enough material for all radiators in a standard house.

This highly reflective bubble reflective multifoil insulation is 4mm thick, meaning it is suitable for all standard radiators and convectors. You will also receive a roll of Double Sided Adhesive Tape which will enable you to stick the radiator insulation securely to the wall, behind the radiator.

expand_circle_down How-To Guides

How to Install the EcoTec Radiator Insulation Kit

  1. Measure

    Measure the length of the radiator using a tape measure.

  2. Mark the insulation

    Roll out the insulation and mark the correct length you've just measured.

  3. Cut the insulation

    Use Multifoil Insulation Scissors or a Cutting Knife to cut the insulation at the length you've just marked out.

  4. Radiator brackets

    Measure the length of the brackets and mark the placement of the brackets onto the insulation as well as the length of the brackets. Cut the line you've just marked so the insulation fits around the radiator brackets.

  5. Tape

    Apply the Thermaseal Double-Sided Tape to the top and bottom of the back of the insulation. Peel the backing off the tape.

  6. Secure the insulation

    Place the insulation behind the radiator and adhere the Thermaseal Double-Sided Tape to the wall.

expand_circle_down Q&As

Do you attach the insulation to the wall or the Radiator?

You will always attach the insulation to the wall.

Will the double-sided tape damage the wall?

The tape shouldn’t damage the paint, wallpaper, or plaster on the wall, but it could potentially leave some residue which could be removed with a product like GooGone. It is designed to last a long time so if you’re wanting to renovate or move your radiators, we would recommend waiting to insulate them until you’re done.

How thick is the insulation?

The insulation is only 4mm thick, so it’ll fit behind all types of radiators.

How do I install the insulation so you can’t see it?

If you’re concerned about seeing the insulation, make sure when you’re cutting and measuring that the insulation is a couple of inches shorter on each side than the size of the radiator.

Can I use a Radiator cover?

Yes, you can use a radiator cover however, they can block some of the heat entering your room from your radiators.

Is the product re-usable?

Our Radiator Kit can be removed if any renovation being undertaken. Once completed, the insulation can be re-installed using more Double-Sided Tape.

How many radiators will this cover?

Based on radiators of 1200mm wide x 680mm height, you would expect to insulate 7-8 radiators.
