Great Window Door Foam
OSI Quad foam is a great product to keep Mother Nature out of your home. It seals gaps and holes around windows and doors, and the low expansion ensures windows will not be warped after curing or long-time use.
Fantastic Foam for Windows and Doors
This was my first attempt using a gun grade foam after using straw grade foams for years. The ease of use and consistent bead has sold me on this item. I would recommend for anyone doing multiple windows and/or doors who wants an easy to use application with a product that provides better protection vs straw grade foams.
We're happy to hear that our product has provided you with a great experience.
Only the best
I like that this product can be used with a foam gun or a straw. There are a lot of foams out there, but this one is my go-to. It will not bend or bow the windows and it also has a higher volume then other cans. I use this with QUAD max and QUAD tape.
We are pleased to hear that you are satisfied with your experience using our product.
