Great Stuff Pro Window & Door – 20 oz Low Expansion, Insulation Foam Sealant – Polyurethane Spray Foam Seals Up to 16 Windows, Pack of 12

Works great!

When my framer finished sealing my 11 windows, i asked him how many bottles he has used, he said just this one... the fine print later i found on the bottle: it can seal 16 windows... I bought two boxes...

Works well when replacing wood windows. Must buy the gun that goes with them. Some of the cans were not emptied in a day but the nozzle clogged to reuse them the next day. Several partial cans we may not be able to use up

It’s spray foam. Works as it’s supposed to, the cans hold a LOT of foam, way more than what you’re accustomed to getting in the swingle-use cans. The dispenser gun is really nice, too. Adjustable flow, extended tips included although I haven’t used those, and the PTFE coating on the dispenser makes it wipe clean instead of being nasty with sticky or dried foam. The cleaner spray does a great job, too. I found that if I have a partial can of foam unused, I spray some cleaner around the nozzle of the foam can to clean it out before it dries and (so far) have been able to continue using the rest of the foam later.

The spray gun is a “should have bought this years ago” tool, and the cans last so much longer than the little ones.

Precision control with the gun! I was able to get great coverage! Very easy to use!

Works exactly as presented and saved us a ton of money by being able to use only what we needed, and what was left in the can could be used later. Also like the small tube because it allowed me to get into small crevices without being wasteful. The foam itself is perfect for using around windows and doors. It doesn’t expand to the point where it’s so tight you jam up the operation of the door or window, but rather just simply makes a firm seal. Nice product.

great alternative for small sizes cans, super happy
