Never have used it to cover a large area but my guess is that if you were trying to cover 14 sq. ft. you would only be able to do about an inch, maybe 2 inches, of depth.
They do not need to be recycled, they are designed to be disposed in normal trash pickup.
The white is open cell, and is not fire block. I am pretty sure pro series means closed cell, and fire stop. Closed cell is also water resistant, but highly expansive, white is not water resistant, and wont crack windows.
Hi, Ralph! Thanks for your question about DuPont™ Great Stuff Pro™ Gaps and Cracks Insulating Foam Sealant. Great Stuff™ Insulating Foam Sealant products should not be used around fireplaces or any other household area where it contacts heat conducting surfaces. Cured foam is combustible and may present a fire hazard if exposed to flame or temperatures above 240F (116°C).
Yes, that is exactly what I used it for. Foam doesn’t expand a lot so plan on getting enough to fill your gap.
Dear DDD: No. It is difficult to form blocks or fill larger spaces with Great Stuff foam. The foam cures by pulling moisuture out of the air, so thicker sections must be filled with successive layers / lifts, with each layer allowed to cure before the next one is applied. It would be much easier to cut pieces of 2" XPS foam board to fit. Look for Foamular 250 at Home Depot. I hope this is helpful. Mark
Yes, closed cell.
Dear pW, thank you for your inquiry. The GREAT STUFF PRO Gaps & Cracks product will work very well as an adhesive for THERMAX in this application.
Dear Ben, The GREAT STUFF PRO Gaps and Cracks product has a flame spread of less than 25 and a smoke developed index of less than 450 when tested in accordance with ASTM E84.
you can but if u let it dry first before sealing
