Spray Foaming the Rafters in Your Attic
If you're using the attic for living space, then you want to spray foam the underside of the roof.
If you have a shingle warranty you're worried about, you can use baffles from your local home improvement superstore. They're easy to install, very inexpensive, and sidestep that issue entirely. You install the baffles first and then spray Foam it Green against the baffles. This makes it so the spray foam doesn't touch the roof at all. Another benefit of doing this that if you reroof you won't need to re-foam because the baffles act as a drainage plane.
Finally, if you're doing the roof, you're sealing off the attic fully to make it unvented. You'll want to reroute anything that needs to be vented outside, like a kitchen or bath exhaust fan that dumps into the attic.
If you do heat during the winter, you should use Foam it Green Closed Cell Anti-Microbial Foam. We recommend 3 inches thick. This will give you an r-21 and a seamless air barrier along with a moisture barrier. Adding fiberglass after the foam cures will raise your r-value even more. Plus the air barrier will allow the fiberglass to work well.
If you never heat during the winter, you can use Foam it Green Open Cell Anti-Microbial Foam. We recommend 3 inches thick. This will give you an r-12 and a seamless air barrier.
Spray Foaming the Floor of Your Attic
If you're using the attic for living space or have an air handler that needs to breathe, then you want to spray foam the floor.
Spraying the floor minimizes the surface area you spray, minimizes the amount of foam you need, and minimizes your bills because you're only heating and cooling the area you live in. In other words, you're not paying to heat and cool the additional square footage in your attic that you don't use.
If you have existing attic insulation, lift it and move it to the other side of the attic. Then you put down just 1-2 inches of Foam it Green. This creates a seamless air barrier that makes your other insulation work MUCH better. Plus the high r-value that Foam it Green gives you helps retain the energy inside your living space.
Once Foam it Green cures, replace the attic insulation over your new spray foam air barrier. Move to the other side and repeat, removing the existing insulation and spraying 1-2 inches of Foam it Green.
Another nice aspect of this is that you can leave the rest of your attic unchanged. Because it's open, the fiberglass or cellulose has plenty of air to dry it out. Now, however, that air doesn't get into your living space and doesn't cost you hundreds or thousands of dollars a year in utility bills.
Spray foam kits are quicker and easier to use plus you get a seamless air barrier and high r-value in just 1 inch. Choose Foam It Green spray foam insulation kits and don't settle for less than you deserve.

"I am a woman who has to fix her house on a shoe-string budget, so I do a lot of that myself. After researching about do-it-yourself spray foam on the internet, I found the Green Foam most convincing due to the videos that made it simple to understand the whole process. It gave me the confidence to try it out and I placed an order. I had to insulate some attic space, sealing in pot light boxes and especially the perimeter of the space and tight niches, where the pink insulation never completely covers. I was a little skeptical at first about the sprayfoam's ease of use — but, as you advertised, it worked like a charm.
It was as easy as following steps 1,2,3 and the result was perfection! My first time use of Foam it Green was a great success! A little tip for first-timers: don't use a cheap alternative — order the respirator that this company offers because it is necessary and effective ( don't skimp when it comes to your health!).
I am truly satisfied with the entire process, from your website set-up, videos, prompt delivery, friendly customer service, ease of use, to perfect results.
I recommended this product to my friends, who were very impressed by the results.
Clearly, the benefits of Foam it Green are its user friendly application and the efficacy of the product — it fulfills its advertised promises to a T!"
"After a lot of research, I decided to purchase SPF from Spray Foam Direct. The information that is provided on their website is fabulous. I would most definitely recommend that any prospective purchaser spend a lot of time reading this information — you will find it unbiased and extremely helpful. The information provided by Phil was also extremely useful and, with his help, I was able to purchase the proper amount of product needed to complete my renovation project.
I live near Jacksonville, FL just a mere 400 ft or so from the Atlantic coast. To say it is a hot and humid climate is a bit of an understatement.
We are doing an entire house renovation using a general contractor. He obtained several bids from SPF contractors and after reviewing their bids, decided that my son and I would able to provide a superior level of insulation by having us apply Spray It Foam \'s closed cell product.
Based on my research, I decided to go with the unvented attic approach by sealing off our ridge vents and the ventilation areas from the soffits. We also sprayed the product to the bottom of each roof panel and then eliminated the fiberglass insulation on the floor of the attic.
The product worked great and I am really looking forward to how much money we will save each month on our utility bill. I am quite certain that the comfort level we will experience inside our house will be far better than before!"

" Foam it Green is a very easy to use product with very helpful technical support in case something goes wrong. We couldn't get our 3rd tank to mix correctly and called the 24 hour 1-800 number on a holiday and they had us up and going in under 5 minutes!
We have a 100 year old house which had serious air leaks in the attic. We installed the product on our rafters in our attic and our air quality is much better in our attic. It keeps it from getting a million degrees in the summer and it's much easier to breath when going up there for storage."
"I JUST WANTED TO TELL YOU HOW GREAT YOUR PRODUCT IS! I AM A DIY'er BUT I WAS SKEPTICAL ABOUT TAKING ON THIS PROJECT. I READ THE INSTRUCTIONS AND WATCHED THE VIDEO OVER AND OVER. I WAS VERY NERVOUS THE DAY I PLANNED TO SPRAY AS MY CONTRACTOR WAS THERE ANXIOUSLY WAITING TO SEE THIS HAPPEN. I HOOKED UP THE HOSES AND STARTED SPRAYING AND IT WAS SO EASY! MY CONTRACTOR AND I WERE LIKE TWO KIDS WITH A NEW TOY. MY ORIGINAL PLAN WAS TO DO ONLY THE ATTIC AREA BUT SINCE IT WAS SO EASY AND LOOKED SO NICE, AND I KNOW IT WILL SAVE MONEY ON HEATING COSTS, I PLAN TO ORDER MORE AND DO THE ENTIRE HOUSE. THANK YOU FOR YOUR GREAT PRODUCT! PLEASE FEEL FREE TO USE THIS AS A CUSTOMER REVIEW!"
