Electrical penetrations, like those threading wires through walls and studs, leave lots of room for air to travel through a home. Plus, if there’s ever a fire, these holes help fuel the spread of smoke and flames. Great Stuff™ Fireblock and Great Stuff Pro™ Gaps & Cracks are fireblock rated and fill those gaps, helping to impede the spread of smoke and flames.
If using Great Stuff Pro™ with Foam Dispensing Gun, follow these additional steps before application:
Helps impede the spread of fire and smoke through service penetrations between floors, electrical outlets and runs through wall studs, pipe, cable, duct penetrations and more.
Bonds to wood, metal, masonry, glass and most plastics to fill gaps and cracks up to 3" while blocking the spread of smoke.
Best can foam gun on the market. I have been an insulation installer for 13 years, and this gun is great! Especially with the tip extensions and getting in those tight spots.
It’s about time…You don’t know how many cans I lost due to poor dispensing
