    Thats expensive at 400 dollars, you can get a contractor to do 200 sq t for about 550
    and I live in Los Angeles, Im sure its alot chealper other places. LA you pay more for everything.

    I wouldn’t trust people to install it themselves. Too risky.

    So you paid $800 to get R19 on 200sf?
    Fiberglass insulation for R19 would cost roughly $60 at full retail.
    So exactly how is this foam which IS without question a better insulator and does a better job, but how are you going to EVER save that extra $740 for every 200sf? The answer to that is NEVER, R20 is R20 doesn’t matter if its fiberglass or denim or newspaper or foam or plain old DIRT and used tires. The foam manufacturers are scamming us for over 1000% profit.

    is DIY spray foam actually worth it and is it safe?

  5. HouseImprovements July 18, 2013 at 2:37 am #

    I believe it has its perks. Small spray jobs, hard to get to residences and remote areas are not that attractive to many big foam companies. They make these products for home use. The cost is high but sometimes it makes sense.

    And i bet you don’t think they deserve to own firearms either huh…. smh

    This was a very good video i feel like i can do it and i had no clue how before watching it. Kudos uploader!

  12. Joe Nunya August 19, 2013 at 4:43 am #

    but at 3″ thick it covers only 200sq/ft for $800-$900.
    That is utterly pathetic.
    Rigid foam with a thermal barrier of 1.5mil aluminum on one side (Rmax TSX 8500) gives you the same Rvalue plus radiant barrier for about $250 for 200sf/ft
    Fiber glass about $60.
    Spray foam is over priced by about 400% if not more.

    About 200 Sq’ at 2-3 inches thick

  14. mtemp2006 August 20, 2013 at 2:38 am #

    For those that keep arguing over the 620 Sq/ft vs the 200. Its 620 sq/ft if you spray it 1 inch. If you make that pass 3 inches thick you devide 620/3 and you get about 200 sq/ft Im not sure if this is open cell or closed cell but that is a determing factor Rvalue closed cell for Rvalue Opencell for sound proof. DOes seem a bit high, I got a 32×20 garage quoted for 1400.00 from a local contractor and with wall hieghts it is 1320 Sq/ft total so 2 kits of this 1800$ and I have to do the work.

    Very interesting and you showed the product well. The cost is rather high though. Most people that are watching these videos are do it yourselfers and for that, the price is rather high.

    Don’t see to much expansion.

    Rigid foam may not be per code. So be careful on what you pick. Radiant barrier requires an air space to work ( I think it’s 2 inches). That is why “spray on” radiant barrier is a joke. It’s radiant and not conductive for those that understand thermal dynamics. If you use the Rigid Foam with radiant barrier, the air space face the exterior. Also if you have a radiant barrier you need to provide a way for the air to circulate in order to get the maximum effectiveness.

  18. Joe Nunya September 3, 2013 at 12:38 pm #

    True on the radiant barrier, but if you are doing this in an attic you simply install the rigid foam over the joist and you have the perfect air space, makes it super easy to install also just throw up full sheets with just a few cuts around the perimeter.
    If installing in an outer wall forget the radiant barrier as it doesn’t matter.
    But the radiant barrier on the Rmax TSX 8500 is also a “more than 15 minute thermal barrier” so it is 100% to code. It is also a vapor retarder all in one

  19. Joe Nunya September 3, 2013 at 12:46 pm #

    In wall installation you simply cut rigid foam to fit with about a 1/4″ gap all around then use canned spray foam to seal it in. I just installed a full sealed crawl space encapsulation in our house which required R10 on the crawlspace walls, stripped out all the worthless humidity soaked fiberglass in the floor joist and then installed 12Mil virgin polyethylene with a scrim layer on the ground. I then installed a supply vent from the plenum to heat and cool and dehumidify the crawlspace.

  20. Joe Nunya September 3, 2013 at 1:03 pm #

    Using the Rmax 1.6″ is little over R10, gave me more than a 15 minute thermal barrier and a bit of a vapor retarder on the walls plus a really good solid flat surface to attach the poly to.
    Cost $816 for about 700 sq/ft for R10.
    Spray foam would have been a huge mess, cost twice as much and would not have been a 15 minute thermal barrier and would not have been a good surface for the poly to attach.
    Spray foam should be costing about 1/4 of what it does.

  21. GoreBullWarming September 4, 2013 at 1:00 am #

    So who sells Rmax TSX 8500 and what does it cost to get R30?

  22. Joe Nunya September 4, 2013 at 11:25 am #

    That totally depends on your area, in my area which is Raleigh NC I found it at a place called “IDI Distributors” they have numerous ware houses around the country. But you would just have to do a search for Rmax TSX 8500 for your area.
    Have no idea what the R30 would be, R10 was $34 a sheet.
    R30 would need to be 4″ thick.

    Man I wish I could get this in Japan!!!!

  24. Adam Jones September 18, 2013 at 10:05 pm #

    I am building a room addition on my house that will be on pier footings. I want to insulate the heck out of the floor. My idea is to use spray foam then follow up with batting. Would this DIY spray foam be a good fit for the direction I am headed. My dimension are 16×16 with 2×10 joist. Thanks!

  25. HouseImprovements September 19, 2013 at 1:32 pm #

    If you are in a remote area and there is not a spray foam company around then this may be what you want. This stuff is not cheap.
