The poor application of spray foam insulation by an untrained or unlicensed contractor can lead to several problems according to fine home building.

Closed cell foam attic insulation problems.

A lot of builders and homeowners are going with spray foam insulation because of the airtightness benefits but then the questioner mentioned that the spray foam contractor had intentionally left big holes to the outside by not sealing the gable vents. It is not however the first solution. We have some evidence from the field that that s not it and if it were the problem closed cell spray foam would rot out the osb even faster. In an unvented attic scenario to limit air leakage as well as any associated condensation at the roof line a continuous air barrier is required.

The problem you saw with the closed cell foam pulling away like that is due to the heat of the foam was to hot. Insulating with spray foam insulation at the roof line will cause moisture problems with the roof sheathing. Choose open cell spray foam when insulating roofs since closed cell foam can trap water from a leaking roof damaging the framing material and roof sheathing. Nothing unusual about that.

It was actually curing out and making foam before it could adhere to the wood. Moisture from the attic another possiblity is that the moisture is infiltrating into the attic from outdoors. Choosing a closed cell spray foam insulation can reduce the noise pollution that exists outside while adding strength to your overall structure. The installer wasn t reading his foam correctly.

Poor application of the spray foam insulation.

He should of stopped and turned down the heat on his hose temp. Removing the attic floor insulation will solve this problem. Poor application includes off ratio spraying of the material bad odors and the lack of adhesion. The american lung association also recommends it for a different reason.

Our builders encouraged closed cell spray foam as it is the best r factor per inch of insulation. Over time trapped moisture can cause serious problems.
