Dow Enerfoam 24 oz Gun Dispensed Foam - 342092

We used this foam to insulate and seal the cracks in a walk-in meat cooler. The dispenser gun is easily to use, the foam goes where you want it and stays there, and with the plastic nozzle that comes with the dispenser gun, you can get into deep spaces and cracks and fill them right up.I would definitely buy it again and the Amazon price is the best I have seen.

it was broken when arrived

stuff works great! dries fast and has many uses. you can let it dry and cut and shape it to meet your needs or just use it as glue.

This is the right foam to use. It's sold as an adhesive, but it works as both adhesive, insulation, and air barrier. Don't make a mistake I made buying the pink insulation foam, which adheres miserably.
