Even if you use the best foam insulation, have the best installation equipment and give your team the best possible training, you aren't guaranteed to complete a job successfully. The secret to a successful project comes from the preparation that you do. 

Here are a few steps that you can take to get ready for success:

Seal, Then Insulate

While foam insulation expands and can fill most cracks, it's still best to use a different compound to properly seal the area you're insulating before you start spraying insulation. Patching or filling holes lets the insulation do what it is designed to do -- block temperature transfer rather than blocking air, moisture or critters.

Isolate Heat Sources

Foam insulation and extreme heat don't mix. If your project is around furnaces, heat ducts or other heat generators (like recessed lighting cans), make sure that you have a temperature seal around them to protect the insulation from the intense heat that they generate.

Allow Air Flow

While holes and leaks can defeat the purpose of using sprayed-in insulation, providing appropriate air flow to vent heat and moisture is also an important part of insulating an attic or crawlspace. Using baffles to protect vents under eaves can help the air keep flowing where it should be, while your foam insulation prevents the indoors from the airflow inside the attic.

Put Safety First

Keeping your team safe could be the most important part of any foam installation job. It starts by installing proper lighting and creating safe places to walk. Providing the right kind of personal protective equipment is also important. That way, you're ready to go on to your next successful job.
