I was advised by my Architect son to put Radflex behind my radiators. I was a bit dubious as I generally make a pigs ear of any DIY (I'll beat Judi to it!
) but I did need to save money this winter. I was able to order it from within Spain, so no faffing with import problems. It arrived within days over a week ago and I've been reading the instructions several times and this morning made a start.
I am amazed how simple it was and I've completed the job!!! The hardest bit was the measuring and fighting off the 'help' from kittens!
It is supposed to reflect over 95% of radiated heat. My son says it made a difference in his UK home and also reduced his energy bills by about 20%. I'll be happy with a quarter of that but obviously time will tell...
