Best Practices for Spray Foam Insulation in a Garage?

[fejog]

Hey everyone,

I’m considering using spray foam insulation in my garage to improve temperature control and reduce noise. I’ve heard both open-cell and closed-cell foams have their pros and cons, but I’m not sure which is best for my situation.

The garage is attached to the house, and I want to avoid moisture issues while maximizing efficiency. Any advice on which type to use, proper prep work, or common mistakes to avoid? Also, is DIY a viable option, or should I hire a professional?

Appreciate any insights from those with experience!

Hi there!

If your garage is attached to the house, closed-cell spray foam is a great choice. It has a higher R-value, meaning better insulation, and it also acts as a moisture barrier, which helps prevent any potential moisture issues. Plus, it adds some extra strength to the walls. Open-cell foam is more affordable and does a good job at soundproofing, but since it can absorb moisture, it’s not always the best option for a garage, especially with temperature changes.

Before getting started, make sure the surface is clean and dry so the foam sticks properly. If there’s old insulation that’s in rough shape, it’s best to remove it first. Also, sealing up any big gaps beforehand will help make the insulation even more effective.

DIY kits are available, but they can be tricky to apply evenly, and if it’s not done right, you could end up with gaps or issues with expansion. Plus, the fumes can be pretty strong, so you’d need good ventilation. If you're covering a large area or want the job done right the first time, hiring a pro is usually worth it. It’ll cost more, but you’ll get better coverage and fewer headaches in the long run.
