Where Each One Wins
Choose Full Fill Pro when…
- You want pro-grade, AAMA 812 low-expansion performance at a competitive price
- You're already ordering firestop, sealants, or PVF — consolidate it into one same-day shipment
- Mold/mildew resistance is called out in the spec
- You reorder foam regularly and want case & bulk pricing
Choose Great Stuff Pro when…
- Your submittal specifically requires its broader listings (UL 723, ICC-ES ESR-1961, CAN/ULC)
- The spec or GC names Great Stuff by brand
- You need a 12 oz or 20 oz can size
What They Have in Common
Both are one-component, low-pressure polyurethane foams built specifically for window and door perimeters — they expand just enough to seal the gap without putting pressure on the frame, so they won't bow or distort it. Both go down with a foam dispensing gun, are AAMA 812 compliant, go tack-free in minutes and trim within about an hour, and are paintable once cured. For the typical window or door rough-opening seal, they're functionally interchangeable — the real decision comes down to spec requirements, can size, and how you prefer to buy.
Never use general-purpose "gaps & cracks" foam around window or door frames. Its higher expansion can bow the frame, bind the sash or door, and even void the window manufacturer's warranty. Always use a low-expansion window & door formula like the two compared here, and fill the cavity only about one-third to one-half to leave room for expansion.
Frequently Asked Questions
Is Full Fill Pro a direct replacement for Great Stuff Pro Window & Door?
They're the same class of product with matching performance and AAMA 812 compliance, so for most window and door sealing they're interchangeable. If your submittal specifically requires Great Stuff's additional code listings (UL 723, ICC-ES), confirm that before substituting.
Will it bow or distort the window frame?
No. Both are low-pressure, low-expansion foams engineered specifically not to bow or distort frames when applied correctly. Fill the cavity about one-third to one-half to leave room for expansion.
Why is it cheaper, or at least no more expensive, than Great Stuff?
It's a pro-grade product from a manufacturer without the consumer-brand premium. The performance standard it's built to — AAMA 812 low expansion — is the same.
What gun does it use?
Any standard polyurethane foam dispensing gun. Leave the can attached with the flow screw closed between uses and use within about 30 days.
Can I use it outdoors?
Yes — it's rated for interior and exterior use. Paint or coat any cured foam exposed to sunlight to prevent UV discoloration.
