3. PRODUCT DESCRIPTION
GREAT STUFF PRO
™
Window & Door
Insulating Foam Sealant is a one
component, expanding, low pressure-build,*
flexible polyurethane foam exclusively
formulated to air seal the gap around
a window or door frame and the rough
opening. The foam expands to generate
an eective seal, and when applied
properly is proven not to distort or bow
window and door frames.
Basic Use
GREAT STUFF PRO
™
Window & Door
Insulating Foam Sealant is designed to
form a durable, airtight, water-resistant
bond to vinyl, wood and metal surfaces.
Its foam skin repels and deflects water,
which can help reduce the potential for
moisture damage in frame openings.
GREAT STUFF PRO
™
Window & Door:
• Expands to take the shape of cracks and
gaps, helping stop drafts
• Reduces pathways where insects can enter
• **Is tack free 3-10 min., trims within
60 minutes, fully cured in 8 hours
Size
See Table 1 for size and estimated yields.
Accessories
Using one of several PRO Series foam
dispensing guns enables pinpoint
application control and no drip dispensing.

Evaluated as an insulating sealant
An air tight and moisture-tight seal
between the dispensing gun and the
can prevents the foam from curing and
blocking the dispensing valve, allowing
the can to be reused. GREAT STUFF PRO
