Hot spots in open cell foam, humidity in attic, what are the best steps to take?
Texas home with summer approaching. We have had some concerns with humidity in the past, using a dehumidifier. I have also noticed the more the HVAC system works humidity and temperature in the attic increases as well.
I decided to rent a Flir to check the insulation performance and noticed quite a few hot spots throughout the attic.
I have had HVAC professionals and an energy Rater suggest a supply and return. In light of this new discovery, I’m not sure if this would be an approach to take.
Is this common occurrence with spray foam insulation? Any suggestions on how to work with what we have and keep a dry, cooler attic?
