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.

Not limited size
I wonder why the product doesn't list its size. tried to compare prices, can't find the size, the photo doesn't clearly show the size of the product. choose something else.
Easy to use
Easy to use, pressure needs to build up when you start to spray

Can this be used to insulate flooring behind oven? I’m in an upstairs condo and I can smell the person living below by the air flowing up behind oven.
