Question: can this be used as a fire stop within a commercial firewall
Document: I have used 4 cans of this stuff and filled all of the gaps, cracks, and spaces on a 76' x 14' mobile home that I am reworking. It is easier to apply and control than the regular cans of Great Stuff foam and it is fire rated.
Secondly, the spray bottles you buy at the Home Depot should be used all at once and not stored for a long time before using or they get clogged. This is true even for the ones rated "reusable". Thirdly, these products are typically not fire-rated. Dow Great Stuff Pro needs its own dispenser gun. You can get the least expensive of the 3 which costs around $30 and will last you a long time if used correctly.
Interestingly, I was doing this to stop a mouse. He ate right through it, but disappeared a few days later- so perhaps not so good for his health.
I love spray foam.This, combined with the pro handle make spray foaming so much neater and more accurate. You can also easily stop mid-can, which is great.
Don't bother with the plastic straw cans if you need more than a couple. Great Stuff Pro with the Pro Gun 13 (or any Pro Gun) gives much better control over the foam bead. When the trigger is released the foam stops - no more foam oozing out after you want to stop. One can goes a LONG way.
Hi, in addition to being a homeowner DIYer, I have several BPI certifications and teach residential and commercial energy conservation, which includes air sealing and insulation. If you are considering using mono-component foam for more than one very small job, be aware of a few related facts. Firstly, mono-component spray foam expands very little, no matter what kind you buy.
I've used it in the past,but could no longer find it in our area so I went to amazon and got it at a good price
Dow Great Stuff Pro Gaps & CracksI have not used this product yet so don't know whether I like it.
The best insulation I've ever used on my drafty windows - a virtual lifesaver in the winter. And I'm sure it will do the same when the heat arrives.
I used this to fill in some gaps around the outside of the house, notably the a/c line where it enters the house and between some windows and woodwork. It does a great job. It definitely puts out more than you need at a time, so be prepared for some cleanup.
Answer: yes
