Best Attic Insulation Method

When we begin construction on new home or if we want to upgrade the home we have
there are several methods of insulations that are available to us. The one thing we all have in
common when we begin any type of construction is the energy efficiency level we want to
obtain. We want to cut energy cost so we can save money and be more environmentally friendly
at the same time. Without a doubt spray foam insulation is the most energy efficient and money
saving option that we have. It may be more expensive than any other method we have available
but the money invested will be well worth it. We will look at the advantages that spray foam
insulation will bring us.
Spray foam insulation is available to us in two different forms. Open-cell and Closed-cellSan Diego Attic Insuation
are both very good options. Take a look at what fiberglass insulation has to offer us. First
fiberglass insulation is the method that is best known to all of us because it has been around the
longest. If you live in an older home go to your attic and notice if your insulation has settled
down over the years. This is typical with this type of insulation. You will have to go back and
add more fiberglass insulation to build it back up to maintain the R-value you want. This doesn’t
happen with spray foam insulation. Once it is sprayed to your attic floors it will stay even with
the top of your ceiling joists and will not fall or shrink. The R-value that you have when you use
spray foam will always remain the same. Even if you have used a blown in cellulose insulation
over time it will settle and your R-value will decrease. Spray foam will hold its integrity for
years to come.
The biggest advantage with insulating your attic with spray foam is the air sealing that
you will obtain. Air sealing has become one of the biggest issues of today when it comes to cutting energy cost. When cutting energy cost and becoming more energy efficient we want to
keep the air we don’t want out of our living areas. The space between our attics and our living
area is known as our ceiling. We all know how hot our attics can get during the summer months.
In order for our homes to be cooler and more efficient we have to keep the hot air from coming
from the attic. This is where spray foam performs at its best. Insulating your attic with spray
foam will seal all of the holes that are around light fixtures, vents, and around knee walls. Spray
foam can be applied in places that you cannot reach with typical insulation methods. Spray foam
can also be applied to your roof to help cut down on the amount off heat that will enter your
attic. Try to do this with fiberglass and see what happens. When spray foam is applied to your
roof and attic it will also provide you with more structural integrity that will make your building
You do not have to take my word for it contact Dr Green Energy today and
see why spray foam is the best method to use to insulate your attic.

    DrEnergySaver Cleveland. can i seal my attic like you did in this video
    with 3/4 inch foam board or 3/4 R-matte plus 3 R3.2 that is sold at home
    depot. if so, would i have to make a box in the raffters so that my attic
    fans and pull the heat out in the summer. i live in deep deep south texas
    were the days are 105 and the nights are in the mid 90. and winter time it
    doesnt get to cold, heck i went to the beech on christmas day. thank you

    why would you want your attic to be warm in the winter and cool in the
    summer? Wouldn’t that mean you’re wasting energy by heating and cooling
    your attic. It seems it would be more effective to place it on the floor of
    the attic to keep those temperatures in the home instead of leaking from
    the home into the attic…….

  • Aaron Powell March 10, 2013 at 10:38 pm

    What about vent’s?

  • Tate Hammer March 17, 2013 at 2:48 am

    no sense in asking anything here, they dont respond back.

  • Jorge Flores April 25, 2013 at 11:05 pm

    What he means is ,to thinking that the addict will be a additional floor in
    the house so insulated like a room.

  • lrd9999 April 27, 2013 at 12:42 pm

    In theory, you’d loose less heat by just insulating the ceiling, which has
    less area. But with many houses, the leakage from ducts, light fixtures and
    hatches, plus problems with air and water infiltrating the ceiling
    insulation, make the losses through the ceiling greater than they would be
    by just insulating the whole attic. I’d rather just see the attic finished
    off and usable; that would get rid of all the pest, moisture, leakage and
    fire-risk issues with vented attics.

  • Shang Tsung May 31, 2013 at 4:57 am

    I don’t know how expensive this is but it looks like a lot! I know it would
    be an absolute nightmare to install. Spray foam is definitely an easier
    install and most likely more affective. Probably cheaper too. This looks
    like it would work well though. Ive been in the insulation business for ten
    years and I’ve never seen this before.

  • MARK PLUGUEZ August 24, 2013 at 4:27 pm

    then you have to heat and AC your attic that your never in. not worth it!

  • randy carreiro September 3, 2013 at 9:28 pm

    you have to get some egress. and even though you can get it in the gables
    or roof .your limited.( iknow dormers ,etc.not going there), then your
    three stories up on a colonial . roof at least a 10 pitch. hope you dont
    need to get anyone challenged(for whatever reason ) its not reccomended..

  • lrd9999 September 4, 2013 at 9:48 pm

    I’ve seen new colonials with finished space in the top half-story, but I
    imagine it’s only allowed for office, den or storage space in some places;
    I wouldn’t want a disabled person sleep at that level, but there are plenty
    of 3rd+ story apartments. In Europe, they seem to be more willing to make
    use of attic space and you almost never see the kind of explosive attic
    bonfires that are common in newer houses here. As I see it, the less void
    space, the better.

  • timofei123 November 1, 2013 at 2:29 am

    i suggest u insulate both the floor and the roof, otherwise u r heating the
    attic for no reason

  • 1timby November 17, 2013 at 5:43 pm

    This doesn’t address those of us with vent-a-ridge roof systems or those of
    us in the south. Also, most homes in my area have roof trusses. That means
    2×4 construction. Seems like a good idea for new construction.

  • Bob Williams December 8, 2013 at 10:44 pm

    These panels look impressive and very effective : )

  • coastnative January 10, 2014 at 10:43 pm

    Nearly impossible to adequately install in pre-existing home

  • shamarone January 14, 2014 at 4:30 pm

    they basically drywalled and taped the attic same as living space with
    something superior to crappy drywall. 

  • Larry Janesky February 7, 2014 at 2:10 am

    You don’t need to vent an attic – you need to vent a roof. this system
    does that. It’s excellent. And it cost zero to “heat” the attic because
    it’s heat that leaked through the ceiling anyway, and then it stops there.
    Its adds no load on the heating system. The reason to insulate the roof
    deck instead of the floor is that the ducts are now in conditioned space –
    very important benefit. Further you don’t need to seal around chimneys,
    can lights, tops of walls and framing assemblies, etc, etc.

  • jimsurveyor February 8, 2014 at 6:16 am

    There is a code violation. Foam insulation needs 1/2″ sheetrock to protect
    it from fire hazard. The foam will emit gas upon heat from a fire. The
    gas emitted does not burn until the temperature raises to a certain heat,
    then it flashes over like an explosion.

  • aguyandhiscomputer February 11, 2014 at 1:35 am

    Seems like you’d be double heating the shingles but I’m sure some will say
    it they can handle it.

  • Freydale23 February 24, 2014 at 1:29 am

    now can i put drywall on top of this stuff and make my attic an extra
    living space

  • sweetiepienumber1 March 24, 2014 at 8:18 am

    Thanks for the excellent product demo, I like the idea. *What do you
    recommend for a 46′ L X 32 W 15.5′ high P-style quonset-hut?* Love the 4″
    and I suppose the R-Value is variable but *what are the parameters for the
    R-Value?* Contractor wants $6,500 for spray foam, but I think it might get
    cooked in the summer here just north of Phoenix, AZ where it is insanely
    hot for half the year or more. And I’m not sure it’s the best bang for the
    buck. I think the contractors are making out like bandits, I would too if
    I could I suppose. Your 4″ product appears something like an attic foam
    “beverage” cooler. T&G might be nice and/or a “quality” lasting seam tape
    that peels off instead at the edges as opposed to the use of sealant for
    every joint. Clearly sealant will be needed when material is custom cut
    and maybe there are so many variables in attic design that one is going to
    cut a lot anyway? I foresee all sorts of versions of this material in
    terms of water and fire resistance in the future and more durable or even
    finished surfaces. However, those products might already exist and can
    even be used in exterior/interior building materials if I recall. I think
    there is even load bearing interlocking foam with more rigid materials on
    the front and back which is used in other countries (maybe here) for fast
    emergency and/or cheap buildings. Pardon me as I am shooting from the hip.
    It’s been a while; disabled remodeling contractor, roofer, and home
    inspector (previous franchisee of a major national inspection corporation
    – too expensive these days!)… Now I’m more of a interested bystander,
    but I know how to search the net :) Thanks!

  • SailingandSuch June 26, 2014 at 7:13 pm

    Why would this method be preferred over spraying foam between the rafters?
    Wouldn’t it be cheaper that way and you would achieve the same thing?

  • John Davis July 9, 2014 at 9:35 pm

    They’re in my attic! Quack quack quack!

  • BubbaInSC July 10, 2014 at 8:16 pm

    And what happens to the Radiant Barrier when/if the roof leaks?
