Frequently Asked Questions (FAQ)
Q: How do I know if the wall is full?
A: You will feel a slight back-pressure on the tube, or you will see a small amount of foam begin to exit the injection hole. Because this is slow-rise, it won't "pop" your drywall like standard canned foam.
Q: Can I use this if I already have old fiberglass insulation in the walls?
A: Yes! The injection foam is designed to flow around existing fiberglass batts, filling the air gaps and "sandwiching" the old insulation to create a much tighter seal.
Q: What is the R-Value of this foam?
A: This open-cell foam typically provides an R-Value of approximately 3.6 to 3.9 per inch, significantly improving the thermal performance of an empty or poorly insulated cavity.
Q: How many kits do I need for a standard bedroom?
A: One 35 cu.ft. kit covers roughly 140 sq.ft. of wall area. A standard 10x12 room with 8ft ceilings has about 350 sq.ft. of wall space; you would likely need 2-3 kits depending on the number of windows and doors.
Q: Does the foam smell?
A: Our "Green Foam" is a water-blown, low-VOC formula. While there is a slight "new car" type scent during application, it dissipates quickly as the foam cures, leaving your indoor air clean.
