💦 SPRAY FOAM CAUSED MY HUMIDITY PROBLEM!
…Or did it? 👀
Here’s something homeowners should know BEFORE spray foam ever touches the roof deck:
Spray foam doesn’t always create a humidity problem — sometimes it exposes one that was already there.
An older, leaky attic can hide a lot of problems because air is constantly moving through cracks, vents and gaps. Once we properly air-seal the attic, problems with the home’s HVAC or moisture management can suddenly become much more noticeable.
Some of the things we look for BEFORE foaming include:
🚿 Bathroom exhaust fans that aren’t being used during showers — or aren’t vented properly
❄️ Oversized HVAC systems that cool the house too quickly and don’t run long enough to remove enough moisture
💨 Improper, leaking or poorly designed ductwork
🏠 Pressure and air-balance issues between the house and attic
💧 Existing moisture or unusually high attic humidity
That’s why Cooler Green Solutions looks at more than just how many inches of foam go on the roof deck.
We want to understand how the HOUSE is working before we change the building envelope.
Think of it this way:
Spray foam can be like turning the lights on in a dirty room. The lights didn’t make the mess — now you can finally see it. 😂
Identifying potential humidity problems beforehand means they can be addressed BEFORE everyone points at the spray foam afterward.
If you’re considering spray foam insulation in West Lake, Lakeway, Cedar Park, Round Rock or the greater Austin area, talk to Cooler Green Solutions about evaluating the attic and potential moisture issues before the foam goes in.
A good spray foam job isn't just about spraying foam.
It's about understanding the building you're putting it in.
