Description
GREAT STUFF PRO™ Window & Door
Insulating Foam Sealant is a one-
component, minimal 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 effective 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 voids, helping stop
drafts
• Reduces pathways where
insects can enter
• Is tack-free in 5-10 minutes,
trims within 1 hour, fully cured in 12
hours**
SIzES
GREAT STUFF PRO™ Window & Door
Insulating Foam Sealant is available in
gun- and straw-applied versions. See
Table 1 for size and estimated yields.
ACCESSORIES
Using one of several PRO Series
foam dispensing guns simplifies the
application of GREAT STUFF PRO™
Window & Door. In addition to enabling
pinpoint application control, an airtight
and moisture-tight seal between the
gun and the can prevents the foam from
curing and blocking the dispensing
valve, allowing a can to be reused.
GREAT STUFF PRO™ Gun Cleaner
simplifies cleanup of uncured
polyurethane foam from dispensing
guns.

PHYSICAL PROPERTIES
GREAT STUFF PRO™ Window & Door
Insulating Foam Sealant exhibits the
typical physical properties indicated in
Table 3 when tested as represented.
Installation
GREAT STUFF PRO™ Window & Door
should be applied at temperatures
between 40°F and 100°F (4°C and 38°C)
at relative humidity
>
20 percent. Surface
where applied should be free of dust,
grease, oil, wax and release agents.
Damp surfaces will not impair the bond.
SAFETY AND CONDITIONS OF USE
• Read the label and Material Safety
Data Sheet carefully before use.
• GREAT STUFF PRO™ Insulating
Foam Sealants contain isocyanate
and a flammable blowing agent.
Vapor may travel to other rooms.
Ensure adequate ventilation. Shut
off all pilot lights and extinguish
open flames; eliminate all sources
of ignition before use. Do not smoke
or use lighters or matches while
dispensing foam.
• Do not breathe vapor or mist. Use in
well-ventilated areas or wear proper
respiratory protection. Isocyanate
is irritating to the eyes, skin and
respiratory system, and may cause
sensitization by inhalation or skin
contact.
