I installed double layers of R3 poly insulation in both the raised subfloor and ceiling of my new build (a total of 1770 sq metres in area) After a lot of research and previous experience of mainstream insulation products that have failed in various ways, I chose this product and it has been fantastic. Easy to install, stapling to timber framing (no strapping needed- anyone can install this ) no itchy skin or irritation. Most importantly, rodents don't like it and it won't absorb water. I also like that the loft is retained as I have found other brands to compress (and soak up water and house rodents) Ecomaster also very easy to work with, facilitating this custom order. Highly recommend
