3M Fire Block Foam Spray Foam Insulation Canister

What Customers Are Saying

The product is generally effective at filling gaps and holes, especially in larger openings, and has fire-retardant properties that allow it to expand significantly. However, some users reported issues with controlling the nozzle, the foam continuing to expand after application, and the product not being approved for certain fire-rated applications. The product can also be messy and difficult to clean up. Overall, the product is useful for many home improvement tasks, but users should exercise caution with the amount used and ensure it is appropriate for their specific application.
