YBS Essentials Multi Purpose Bubble Foil Insulation Roll | 600mm x 10m, 3.5mm Thickness | DIY 3-in-1 Thermal Reflective Insulation | Radiator Foil | Roofs, Walls, Floors, Motorhomes, Cellar & Garages

I haven't used this to put behind my radiators (not in a heatwave) but what I have done is stick it over the windows (with double sided tape at each corner) so the heat from the sun is reflected away. I have a lung problem and find it difficult to breathe when its as hot as it is so product has fitted the bill nicely and does keep the rooms nice and cool. It's easy to cut and will probably reuse behind the radiators in the winter.

All I can say Is that after using this to cover the inside of my new shed I just want to throw away all the tools and turn It Into a Man Cave. This product has made so much difference to the temperature that I think I'll move In. Great quality and easy to use.

My home warms up twice as quick

bought this to make window covers for the inside of my RV. I covered cardboard and used stick on velcro pads to fit to windows. Works well with the silver tape also purchased, will keep heat inside in cold and sun off on hot days, much cheaper than buying ready made window covers

Easy to use. You will need a stapler, light duty is fine.

Very foil. Great value for money .

As described

Good quality product
