  • nov51947 March 8, 2014 at 10:31 pm

    How about doing this on foundation walls in a crawl space? Any issues?

    can you use this to insulate a basement in MN?

  • Rovert Robert March 17, 2014 at 3:01 am

    could I do this for a cathedral ceiling and consider the gap behind the
    closed cell solid foam as my air space? My rafter joists are only 2 by 4
    so I don’t have a lot of room to use the air space stryofoam and
    insulation.

    not bad…2″ foam in a 3 1/2 ” cavity gives you an air space between foam
    and drywall,it’s best to avoid air movement!.

  • undrline April 11, 2014 at 6:18 pm

    I don’t get why you are purposely leaving a space. Why wouldn’t you do
    this as tight as you can get it, then do the foam the same way?

  • efilnikufecin2004 April 22, 2014 at 6:29 am

    Considering how little you get from a $5 can of great stuff, and how much
    you would need, and the cost of the foam board insulation I think watching
    a few videos and reading the safety information a person could do the spray
    foam for less than would be spent doing it this way.

    Seems like if you cut the foam panels to fit tightly, you would get an air
    tight seal without adding foam and just use this foam sealing method on
    those panels that ended up loosely cut so as to not waste material by
    having to re-cut another piece.

    Thank you.

    Don’t pay any attention to the haters. They have obvious mental issues and
    need anger management classes. I guess they just can’t see how ridiculous
    they sound complaining about a basic video showing a simple tip. Like they
    can’t just watch and shut their pie holes. Dorks are everywhere. Thanks for
    sharing.

  • Rafal Jarosz May 13, 2014 at 5:36 pm

    Can I use .25 foam board and fiberglass In the same cavity? To eliminate
    air gaps. 

  • Otis Tinklehofften June 8, 2014 at 11:59 am

  • Valurie Tonga July 1, 2014 at 11:47 am

    Thanx :) very helpful 

  • prank diver July 3, 2014 at 12:41 pm

    @corey binford , where can I buy spray foam? I have only seen the ones that
    comes in the can.

  • Sharon Hase July 7, 2014 at 11:50 pm

    So what is the cost per sf…….that is the only way to know your savings

  • David Hamrich July 8, 2014 at 9:04 pm

    If you’ve ever priced spray foam contractors or even DIY kits, you’d
    realize this would be an amazing savings..

  • Les Stella July 15, 2014 at 7:41 pm

    Where can you get the tuff-r? I can’t find it anywhere.

  • John Fenman July 16, 2014 at 5:03 pm

    If you are in a hot climate like florida, you can turn that r12 to r60 by
    using ecoblock.
    The key is to have 4 inches of cement and rebar between 2.5 inch inner and
    outer layers of high density foam so that the inner core temp rises in the
    day, cools in the night and on average just stays the same temperature.
    That mass between insulation is the whole magic – way more effective that
    one larger insulating layer. Means I can central air 5000 sq feet for maybe
    $150 a month.
    Quick summary – ixnay to wood framing. Never never. But do insulate all
    interior walls and 2 pound per square foot foam underside of roof 4 inches
    thick.

    Beware – the good foam is waterproof and will make it harder to ever find a
    leak. I recommwnd a double roof with vent between so sun never gets to your
    inner roof. Or better make your whe roof a greenhouse. Glass beats shingles
    and attics are a waste.
    Design right up front.

    2″ provide a rating of R 12, Northern states recommend a rating of R 19 in
    walls. 3″ of spray is R 21. 

  • Tcat Houser July 25, 2014 at 4:12 pm

    Wonderful logic. Thank you.

  • Spray Foam Insulation Tucson August 13, 2014 at 10:46 pm

    Nice not as good as spray foam but if you are on a Budget this would work
    better than reg insulation

  • Tom Skaggs September 6, 2014 at 11:54 pm

    Is have to stud the block walls out!

  • Jeremy Hall September 30, 2014 at 7:51 pm

    Corey, I may do this to insulate my attic ceiling, but I can’t find the
    Tuff-R for sale anywhere. Home Depot doesn’t seem to carry it anymore, and
    I can’t find it online. Any ideas, or have they discontinued it? If so, do
    you have a suggestion for a replacement? Thanks.

  • truesoldier27 October 3, 2014 at 3:37 am

    This is a ridiculous idea and I don’t know how any inspector would pass
    this. I’m sorry for being so negative but just the fact that you seem to be
    offering insulation services and created this video is a huge red flag for
    me to never hire you. For those out there that are thinking of trying thos
    ridiculousness just go but a roll of unface fiberglass insulation then
    cover the whole wall with plastic as the vapor barrier. Smh
