8. Be Careful,

and read the directions to get the right kind. Some of those urethane foams expand so much that you can blow out drywall, warp door jambs, and bend window frames.

9. And in most cases

You need to use up the entire can at once or else it hardens in the sprayer

10. Oxygen deprivation hazard

Make sure fresh air can still get in house. Carbon Monoxide builds up without outside air.

11. Great Stuff, Window & Door Seal. There aqre tow types. Low expansion and High expansion.

Use low expansion for door and windows. The high expansion can put too much pressure on stuff that slide and swing.
