Is this suitable for hvac insulation?

I used the bubble wrap for my crawlspace aluminum duct plenum and yes it helps a lot to keep the heat in the plenum or AC. Leave a gap between the steel and the wrap. Use pieces of bubble wrap taped or wrapped around the steel plenum every 2' then simply wrap the whole plenum. Crawlspace are a pain, however so be prepared to work in there.

Can I attach it to a tarp to insulate my attic pull-down stairs? The ladder extends more than 20 inches when closing and opening the door.

I guess you could attach this to a tarp using double sided tape.

can I sew a binding on this?

Well... Sure, but I'm not sure why you'd want to. It's fairly stiff, not the sort of thing you'd make a blanket out of. OTOH, if you just want to give the edge a nice finish then sure, I guess so. I don't think it'll come apart.

Where can I order more I need 6 rolls only 2 instock
