Closed cell spray foam insulation can look different when installed based on the type of project and the size of the space. A homeowner from McLean, VA recently asked us what the end-result of our spray foam installation looked like. Here are some examples of closed cell spray foam installation.



In general, surfaces that are accessible and large in area result in a better-looking installation of spray foam. The foam expands to 40 times it's liquid volume, so even minor application issues where "extra" foam is used can create an amplified appearance. Foam expansion ensures the space is airtight, properly sealed and conditioned.


Spray Foam is used in sealing and insulating the walls and rim joists of crawl spaces.  One of the services done well by 3 Pros Basement Systems when treating your crawl space.
