Open Cell Foam Insulation Issues

Recommended Posts

I have recently installed more lighting in my 2 attics and several deck panels for ease of walking. I have noticed that the spray foam job my contractor provided has several blisters, voids, hills, and valleys. Also, some of the wall king studs do not have foam in them (see photos). BTW the house was framed with 16 to 20 gauge steel.

Is this normal for open cell foam insulation application and if not, what can I do to correct the problem?

Thanks, Jeff
