How do I liquid foam insulate a pressurized wall that’s already been put up? Can I drill holes and inject?

Posted on October 28, 2009 by admin

I have a 15 foot wall that was recently put up (pressurized/temp wall) and unfortunately there was no insulation put in the wall. I’m trying now to rectify the situation with some liquid foam insulation or another method. How would I do this? Thanks.

If you inject the liquid foam into the wall, stand away from it because you will blow the whole wall out. Then you can clean up the mess and rebuild the wall putting insulation in it this time.

There is a light weight particle insulation that can be poured into the wall through a few holes near the top, then patch the holes. See your local building supplies store.

    soon as you drill your holes your pressure is gone i would think? I dont know if you could get that back again. Contact the wall manufacturer.
