A: 32 Sq ft for all 6 rolls. It is a good product.
A: Well , if you do the calculation , one bag is 5.3 square feet so times 6 bags is 32 square feet , so the answer is all six bags , hope this helps , SB
A: Each roll measures 16” x 48” which is 5.33 square. feet. So 6 rolls would equal 32 square feet.
A: I don't know that there is a significant difference in R value but I would have to reference that info on each product to make that determination. If your using the trailer truly for cargo then I would choose the rigid styrofoam boards so you won't defluff the denim- although it dense and extreme difficult to cut through. Another consideration would be concern over the denim absorbing oil or flammables. If your outfitting your cargo trailer for overnight trips/ camping I would go with the denim to avoid the offgassing of rigid panels-particularly the pink ones.
A: I think they are both comparable. I used both in a remodel of my rv. I have used this denim in several tight fitting places. I have been very pleased with the denim insulation. It is also easy to work with.
A: Open and allow to expand before installation
A: I have only used this insulation as a "green" product for my new home construction in stud built walls. It is a very light and "clean" option compared to most other insulation products but does a very poor job of sound deadening/absorption. Net-net, I wouldn't recommend it for typical insulation project applications.
