Before I had the work done, I left my electric heater on all night and in the mornings the living room was 14 degrees. Now with the insulation completed, I don’t even turn the electric heater on over night and when I check the temperature it had actually risen to 16 degrees. It may not sound like much, but it makes a massive difference to my home and I highly recommend Platinum as I now have a much happier and healthier living environment.
