We have a small additional attic bedroom with a sloping roof, the insulation is poor and I want to replace it with something better. On TV I have seen an ad with someone unrolling a fully enclosed "quilt" in a long narrow shape, designed to go between the joists. What is this called and is it widely available? We have access from above and below the slope so I reckon I can cut it into lengths, seal the ends with tape then pull it down into the space between roof and ceiling from below.
A second question: we have about 8" of glass wool throughout the main attic and I'd like to add some more. However I understand that adding more gives diminishing returns, so I reckon I would do better to lay some kind of dense but light blanket on top of the existing wool so as to trap warm air like a duvet. Does anything like this exist?
