Leftover from our remodel. Can lookup on Amazon too, to see this is the primo brand of closed cell expanding foams. Sticks great, sprays evenly, and 1" thick coverage us better insulation than 8" rolls of fiberglass Insulations and you spray it on, don't have to build walls for it specifically.
Enough to do all walls of say a 4 block high crawl, or really punch up the efficiency in an attic that only has blown in insulation on the floor by spraying the under side of roof as we did.
This is 750$ per kit bought straight from manufacturer. Have 3 sets unopened left over. Would take a good bit less as we are done and just order too much but have other projects wish to get started on so hoping someone wants to save money on their bills and help me replace our broken dryer while they're at it. Might be up for a trade on a Dryer plus cash too.

TF-600FR – Our most popular formula, this closed cell, fast rise foam is designed for new construction and application to open surfaces. Unlike many of our competitors, this kit comes ready to spray with a 15 ft Gun/Hose Assembly, 8 dual-use nozzle tips, and kit preparation instructions.
