help needed best spray foam for insulation gaps

[WrapAndTrap]

My friend is fixing up his old brick house and is looking to improve some weak insulation areas around the walls, particularly around pipes that could freeze. He's planning to use spray foam to fill in gaps, like the area behind the washing machine.

What kind of foam would be best for this job? Any advice or things he should be cautious about?

For insulating gaps around pipes, especially to prevent freezing, a closed cell spray foam is best coz it provides good insulation and moisture resistance. Your friend should be careful not to overfill tight spaces, as spray foam expands a lot and make sure pipes are dry before applying. Lastly , proper ventilation is the most important when using spray foam indoors. good luck

great explanation and I would only add to let it cure before covering. Check the instructions for the detailes, but I think he'll be looking at at least 24 hours of curing time

Closed cell is definitely the better option for spots like that. But do tell your friend not to go wild with the can as it expands fast. A little goes a long way, and yeah, ventilation is crucial unless he wants that chemical stink hanging around.

Yeah, for improved insulation and moisture protection, opt for closed-cell spray foam. Make sure to keep the foam away from heat sources and electrical connections. Great Stuff Pro is a solid choice for DIY projects.

Always keep in mind to be careful not to seal up any pipes that you might need to get to later. It's such a hassle when you realize you can't access something that needs fixing down the line.

If it has big gaps or leaky spots, backer rod or caulk before foaming. Saves you from using way too much foam later.

Thanks for this! I've heard Great Stuff Pro is closed-cell. Does it hold up well in warm, dry climates? Also, how far should I keep it from outlets or wires if I'm just sealing around them? Trying to stay safe but still get a good seal.

They are right! Just make sure there is good ventilation during application. It is important because the fumes can be strong until the foam cures.

@itsrainingtac0s Yes, you can use it in warm and dry climates. It is highly recommended. Just put the wires inside a conduit for protection for easy removal if needed.
