How To Use Open Cell Foam

Customer Top Questions & Answers

What is the R-value of Open Cell Foam It Green?

R-3.6 at 1 inch.

What is open cell used for?

The most popular open cell projects are internal wall sound deadening (if not a bathroom or kitchen), or spraying on the ceiling of a basement in a conversion to a home theater. Closed cell foam should be used for any exterior walls or basement walls, rim joists, etc.

I need 400 board feet of closed cell foam but your sizes are 202 and 602- can I just use this instead?

If your project calls for closed cell, stick with closed cell. Get the 602 kit, and you’ll find there are probably other areas you’ll want to use the rest of the kit on when you’re done with the 400 board foot project.

Any tips for spraying open cell?

Open cell is less forgiving that closed cell foam. Don’t use the fan tips right away – get a feel first for laying down about 1/2 inch of wet foam with the regular mixing nozzle. This will cure up to about 2 inches thick. Going for 2 inches in one pass with open cell gives you the best yield.

Can I spray this overhead?

Open cell is less forgiving than closed cell, so it’s important to follow these steps if spraying any foam, but especially open cell overhead. First, cover anything you do not want foam on. Then, get closer to the surface than for normal spraying, spray 1/2 inch of wet foam, which should rise up to about 2 inches. Balance the pull of the trigger to avoid overspray from blasting it on, and never use the fan spray tips.

Why is this called Dual Purpose?

Our closed cell foams are either fast rising (30 second setup) or slow rising (2 minute setup), but the rise starts right away as you spray it on. Open cell sprays on as wet foam but only starts to rise after about 45 seconds, and then sets shy of the 2 minute mark. This allows you to use the dual purpose open cell as a slow rise product for filling blind cavities or as a fast rise foam for an open vertical wall.

  1. Went great and quick. Nice to use a product that is as advertised- don’t find Christian honesty much anymore.

  2. Everything worked great. Thank you for not skimping on the extra nozzles. They came in handy. Great product.

  3. The kit is the best thing since slice bread. You can install at the time you want, not when they have time to come out. The kit has everything you need to do the job right. I will tell everyone I know that is doing this kinda work. This product is the best I have ever used.

  4. The experience with Foam It Green was similar to walking into a deep green forest for the first time. At first, along with the excitement for a new experience, there is a little trepidation and fear of the unfamiliar. But talking on the phone with the representative helped to quell the insecurity involved in trying to enter into this uncharted territory for the first time. The people I dealt with were very courteous and clear about every step involved in this project. When I received the product it was also very clear and simple as to how to go about the procedure with plenty of tools and equipment to get the job done properly. I would recommend this company for those who want to insulate their house on their own, especially without prior experience.

    Two benefits of being able to do this on our own were to be able to control how much coverage we wanted and when and where we wanted to do it. At first we were depending on an outside company but they were not reliable enough to get it done when we wanted to and never finished the job they started.
