Unvented Attics Insulated with Spray Foam

Foam Insulation - Great movie segment courtesy of Ted Medford and AirTight Insulation and LaPolla. Ted explains all the reasons why unvented attics insulated with spray foam insulation are much more energy efficient.

Home energy now you are crazy. You can fill your attic with a r60 of blown in and it won't be air tight. 3" of closed cell will outperform any other type of insulation and it will be airtight. Plus if u look at the return value the foam pays for it self over a few years by giving you lower utility bills.

@HomeEnergyNow step aside, or change your incorrect mindset and join an industry of the future. You are the asbestos of the 21st century. I bet you sell fiberglass. I have foam and removed all my fiberglass, I saved 45% on my first following power bill. AND I was able to step DOWN my ac unit size, plus a tidy tax break!! WAKE UP!

This may be a good product and good installer but he doesn't understand the physics of what is going on. Too much magic and sales pitch for my liking. Of course, other viewers and buyers may not want the physics to be clearly explained.

the stuff works

If you have an extra 3-5k$ to put into you house, simple math will prove it is better spent on a higher efficiency HVAC system than to spend extra on a product that increases the btu load vs. lower cost alternatives (cellulose r-60, fiberglass loose-fill r-60) basically foam is working backwards. You can seal a home tighter than foam for less than 450$ labor and material on the avg. home. But it is NOT wise to use mechanical ventilation for fresh air, it will fail, why risk an unhealthy home.

@AlexisJordan77 That is what all of our builders customers say too, except no foam. New homes are typically much more efficient because of EER, AFUE, tighter building methods, better windows, higher r value requirements, among many many other things. I hope your contractor knew what they were doing and made sure you are getting fresh air. Foam houses when not maintained properly (air filter, erv maintenance, air intake kept open and clean of crap) are hazardous to your health.

@HomeEnergyNow I may not know alot about btu loads but I do know that my utility bill is alot cheaper than previous home and more sq footage. And there may be more fiberglass being installed but that does not tell me it is more superior than foam. There is alot of cheaper things out there being installed (windows,doors etc.)but that don't mean it is better I just make my decision from results.

@TheJsf123 I take it you know nothing of home energy, or btu loads? Loose-fill fiberglass would have cost you less, and saved you more money. I am sure you know that though, since you that even though fiberglass is"old school" it is magically appearing in over 85% of insulation projects today. Foam has never creeped past 5% hilarious, I know.

The baffle isn't for heat, it is for moisture. That is why YOUR PRODUCT will void all OSB warranties. Go to the natianal OSB manufacturers website. Conditioning your attic makes no sense. Applying insulation to the roof deck increases the homes conditioned space, and envelope sqft. increasing the overall btu load. Claiming it is superior only makes you a liar. Trying to sell a product based on those lies makes you a con artist.

This video says it all. I am glad your company took the time to do this.
