Does what it claims to do,
Verified Purchase(What is this?)
This review is from: Radflek Radiator Reflectors (3 Sheets, Fits 3-6 Radiators) (DIY & Tools)
I purchased this as my walls are un-insulated & I felt I was loosing too much heat through them.
The product is easy to install, though each pack won't cover as much as they say, the instructions say install behind rad between supports, I felt a better solution was to cover the whole rad, that means one sheet does one average size rad.
The rooms do get warmer quicker but more importantly prior to fitting it was noticeable how warm the wall behind a rad would get, with this added it doesn't. I was also wondering how this managed to get better performance figures than the main competitor, using it I realized that's likely due to the air gap that this creates between the wall & the sheet, effectively adding another layer of insulation.
I notice the sheets also claim they will reduce your CO2 emissions by 12 Kg per M2 for insulated walls & 18 Kg for un-insulated.
