Superior post, however it looks like you can chalk up Practically all of those problems towards the knowledge degree of whomever is spraying the foam. Spray foam isn't really an inherently terrible solution, but it really's pretty simple to botch In case the employed firm is inexperienced.
The common price tag to cover 200 square ft that has a foam insulation package will operate between $300 and $600 (about two to a few kits). Within these kits is one area termed Icynene, a foam produced from two liquids that happen to be heated and pushed via a gun over the can.

You've no argument from me there, Dennis. Getting a good installer if you're going with spray foam is essential. Quite a few builders or homeowners don't know how to find a single, nonetheless, and that's in which third party inspections are available in.

The fellows who sprayed my attic had been properly trained and Licensed, but I later on discovered, way too late, that they had no expertise and my attic was the main they'd ever sprayed. I was also under no circumstances instructed to vacate my residence for virtually any length of time, and so I (and my pets) have been in your house the working day they sprayed and your complete time the off ratio foam was filling my residence with horrendous vapors. The corporation stored telling me that it was a superb career And that i had practically nothing to worry about, even soon after I would had 2 other skilled sprayers from 2 different corporations visually take a look at the foam and ensure that giant places seemed to be off ratio. The 3rd sprayer from Yet one more corporation, was also outraged since the corporation who did my attic experienced failed to vacuum up all the aged cellulose insulation, and he also recognized regions in which the foam was shrinking or pulling absent, and this was not even five weeks once the spraying. That is in fantastic distinction to my Buddy's encounter.

I'm developing a property in Central Texas (Caldwell). Several builders are careful about employing foam insulation and/or a shut attic. I wish to use equally. Listed here in Texas, heat and humidity (except for the earlier number of years of drought) absolutely are a continuing challenge. Which kind of foam would be the ideal to work with in our home, wherever must the vapor barrier be or need to be use just one in any respect, if we've been using fans in the outside partitions to supply fresh new air to the home, do we'd like a vented attic or will it trigger extra difficulties than it address?
We've been turning our roof into an unvented roof assembly by elevating the roof and blowing in SPF. We are planning to go away the prevailing vapor barrier down but take away the fiberglass batting after which incorporating six" of SPF in each of the cavities, to absolutely seal and insulate the home.
