Amazon review for SuperFOIL products

Easy to use, cut to size without any waste once measured carefully. Something I've thought of doing for many years but, never got round to it. Intend to sit back and hope it preformed as promised, I'm sure it will since the product is hailed by the experts on energy performance and importantly enough for seven radiators. Definitely recommend. Thank you..

Google review for SuperFOIL Insulation

Superfoil products radically simplified achieving the required insulation ratings for our renovation / extension project. I was very keen to maximise internal space in both the dormer spaces and a very large flat roof avoiding tall external build up. The technical team provided detailed options and then were more than happy to iterate these to refine the final solution. I ended up using a hybrid solution of SF40BB and SF40 along with Vapour barrier and mineral wool. I would recommend speaking to the tech team – they certainly allowed me to get the outcome I wanted.

Amazon review for SuperFOIL products

Very pleased with this kit and within about 2hrs it was installed. The insulation most closely resembles bubble wrap however was much thinner and behaved more like cardboard. Very easy to cut with a pair of scissors and the supplied double sided tape is good quality. The 100mm wide tape is a bit fiddly as it is wider than scissors and tears easily however with a bit of patience it worked well. Installation – The insulation comes in 600mm wide rolls which is a bit smaller than I needed to do a full horizontal section, I decided to cut twelve small individual panels, plus two full width strips to finish with. I stuck the double sided tape all around the outside edge on each of my three horizontal areas, I also sprayed contact adhesive onto the metal door inside the tape frame. I then used four of the small panels on each area with around 10cm overlap. I finished by running double sided tape along the horizontal bars that were remaining and covering with the long strips of insulation. Finally, I taped between all of the sections to create one large airtight piece. The contact adhesive probably isn’t needed however at £6 for a spray can on Amazon I thought I may as well secure it properly. Final results are a noticeable reduction in outside noise and a lot more light in the garage for working on my bikes, hopefully it makes the garage easier to heat in winter and not allow the temperature to get too high in summer. We’ll see! Garage door opens and stays open with no obvious strain on the mechanism from the additional weight. Overall very pleased with the kit and a bargain imo.
