We put pink foam board insulation in the exterior wall when we renovated our bathroom a couple years ago. We used Great Stuff pest block to seal around it and make sure there were no air gaps. It didn't have any immediate bad effects on the foam board that we could see and after we put up drywall it still seems to be well air sealed today so it seems like it worked fine.
There is another variety of Great Stuff specifically designed for doors and windows so that it does not expand hard enough to push your frame out of alignment. It doesn't specifically say the pest block will cause a problem, but if they have another variety designed so that it will not warp your frame, I assume that pest block or one of the other varieties could possibly warp your door or window frame.
Would probably work. Might take a lot of product. Could be toxic to the tree or birds that might peck at it. I'd probably look for another more natural solution.
The foam is temporarily set Interior or exterior
Hey there Raven, As with all spray in foam sealers, they are very flammable !! the gas in the can and vapors can burn. Now there is also a Fireblock type of sealant that will impedes the spread of smoke and Fire, and it takes the heat better then other types. Mouse
Manuel info is on the can
Why would you remove this nozzle? You might cover everything, including yourself, in the most sticky (and I do mean STICKY) mess. If you do remove the nozzle, please post the results on one of the media outlets on the internet. Practice with a small area first, then learn how far you can throw the can while cursing.
They make a seal tape for your pipes, the foam is highly flammable
