Review: Great insulation – exactly as expected - Used this in my camper van and it does the job perfectly. Easy to work with, no irritation when handling, and provides good thermal insulation. Quality is exactly as expected and it performs just as described.
Review: Shed insulation - Purchased to insulate walls & floor of shed from winter cold and summer heat. I can't offer a review on the materials effectiveness as I'm only just installing it. What I can say is, is that it is easy to handle & cut to required size with decent scissors, rather than having to resort to a Stanley knife, and no gloves required. Not sure how flame retardant it is, but given the shed is corrugated plastic and the framing & boarding are wood, the shed will go up like a bunsen burner if a fire breaks out anyway! The insulation is 50mm thick, my framing is 37mm, so I'm aware it will be loosing some of its effectiveness by condensing it behind the boarding. Would have been better if alternative thicknesses were available but hay-hoo. As the shed is modern, thin corrugated plastic I needed to frame and board it out so that I've got something to screw shelving to so installing insulation between the two isn't much extra work. I don't think I would have gone to the trouble of insulation with a traditional timber shed, but plastic sheds have a single piece apex roof so the pay off is no leaking roof period. I wouldn't use this stuff in my loft TBH, I'd go the extra mile and use sheep's wool. Thicker, more effective and 100% eco friendly. Expensive mind but worth it. J D Dewsnap.
