Looking for opinions on Froth-Pak spray insulation (DIY)

[BLAHUT]

Not sure of the brand? but friends have had their houses done, when complete, were wondering where all the kids went, did the wind stopped blowing, could not here any of it, anymore ? Tightened up the houses.

I just have a small area to do (from the outside).

it works, its expensive. mask off what you dont want over spray on and go slow, a little goes a long way. might want to practice first before you do the actual area. kind of like painting a car. get extra tips so you can stop when you need and be able to restart, otherwise you have to go go go to keep tip from plugging.

Used one decades ago on a wall that had infiltration so bad you could feel the breeze. Heat bill dropped significantly. Good advice on extra tips. If you let up on the trigger change the tip.

Use it on my foundation every 10 years or so... did my front porch which was a giant air leak... expensive but it works well to seal drafts.

Might be like spraying your house with kerosene.
Test the hardened foam for fireproof
Made a chunk of foam, let it dry
take it outside
put a match to it.
Urethane foam is nasty when it burns, lights with a spark.
Some spray foam is rated fire-resistant
compared to urethane, anyway.

A melted electrical outlet could make a bad smell
or be impossible to put out, depending on flammability.
Just saying.

Yep, I'd make sure it is fire resistant, if not, I'd not use it....

Nice insulation

BUT it is also a PITA
As I used to do electrical work
With the spray foam installed
It is hard sometimes to add new circuits or run low voltage ( coax or phone wire )
As with most insulations a fish tape will be easy to push through
But with spray foam , it is dense enough to make things tough

So BEFORE you add the spray foam
Add any extra wiring you think you might want later
I used 12/3 Romex to wire all my exterior walls
So I could add extra circuits later if I wanted them

Friend did his entire garage 6" thick. We ran conduit everywhere to junction boxes. Basically a grid pattern across the ceiling and down the walls. Can run a wire tot he next junction, change direction, run it up to the ceiling etc... used triple gang boxes so another outlet could be added if needed, or a switch... Also ran air lines, low voltage ethernet/phone/camera system... put in enough ethernet ports to plug a computer in in 4 spots on each long wall, phone line sits unused now with cell phones, he has wired security cameras in there to watch for break ins... he has some expensive street rods in there and enough tools for a NASCAR garage!
