Fred99:bfginger: Are you sure that isn't retailer margin?
I can see someone selling Mammoth R3.6 polyester ceiling blankets for $16m2. Mammoth Multi is R1.9.
Greenstuf, Insulpro and Cocoon are the other brands of polyester.
I'm not sure if it's retailer margin and/or in the case of Placemakers, commercial bias in favour of Pink Batts. I mentioned the deal I got for Knauf Earthwool to the sales dude at Placemakers, and got a FUD lecture about foreign manufacturers, different R ratings. All BS - Fletcher is a mere peanut in the global market compared to Knauf.
Insulation Warehouse is selling Greenstuf R1.8 underfloor polyester for $11m2. Have you tried ITM?
