Existing Walls (closed cavities)
Foam has developed a Slow Rise formula that uses the patented Handi-Gun
to pour insulation into closed cavities through a half-inch hole. This
procedure is simple and safe with FOMO Foam's slow rise (SR) formula.
The SR formula has a
delayed foaming agent, permitting the liquids to gravity feed to the
bottom of a cell and then start to rise and slowly fill without the
pressure of fast rising foams. It's designed specifically NOT to blow
your drywall off the wall!
If you have an older home that is in good shape, but there
just isn't ANY insulation in the walls, you can fill all of your outside
walls with the slow rise product. It's a bit expensive to do all at
once, but who said you have to do it all at once? One II-600 (SR) board
foot kit will fill approximately 200 square feet of wall space, just
measuring your walls from the inside and discounting for the 2x4 studs.
The more studs you have, the more coverage you'll get, of course. That
also takes into account average window surface. Again, the more windows
you have the less foam you'll need. But, 200 sq. ft. is a good average.
If you have NO
INSULATION, like a lot of folks do who live in homes older than 20
years, you can reasonably expect to cut your heating and cooling bill in
half, at least. It doesn't take much figuring to figure this just makes
It's common for a big,
old two story house to cost $400+ a month to heat. If you saved half of
that each month, you'd pay for a kit every 3 months. If it took even 10
kits, they'd pay for themselves in less than 3 years! Then you'd
just be pocketing the extra couple of hundred a month.
Even better, say you
have 1200 square feet total outside walls to insulate. That would cost
you about $3,600. If you got a loan from the bank for $3,600 - your
payment would be about $85 a month. Now, every time that $85 a month was
due, so would be your utility bills. If you saved $200 on utility bills
every month and paid $85 of it to the loan, you'd be ahead $115 each
month or $1,380 a year! Just by using the banks money and your own
The Handifoam SR
formula is a sure fit that you can do in your own time. Drafty, cold and
expensive to heat and cool old houses don't need to be that way.
It just makes $en$e.
If you have SOME batt
insulation in the walls and it's OLD and Thin and you want to use Slow
Rise formulated FOMO FOAM, you can. You just need to use the "Tube
Method" of installation. Just go to a hardware or supply store and
purchase inexpensive 1/2" I.D. (Internal Diameter) clear plastic,
flexible tubing. It comes in 10' to 50' rolls and is similar to the
tubing used in fish aquariums and the like.
2 to 3 foot sections of the 1/2" I.D. (Internal Diameter) tubing.
One end will slip neatly over the spray tip on the FOMO Handi-Gun? that
is included with your kit, and you can use it to feed into the cavities
through the 3/4" holes you would drill in the FULL
as outlined in the Soundproofing
section of this site.
A COLD ROOM UPSTAIRS ABOVE THE PORCH?
is especially common in older homes that there is no insulation at all
in the wall where the porch connects to the house. One hole in each cell
& enough SR to reach the top of the roof will solve that problem!
Mr. Foam Inquiry:
Mr. Foam, my question is: I own a home that was built in 1968 and has
little to no insulation in the wall.
Could you supply me with a math formula to calculate how much
product I should purchase? An
example of what I want to insulate is an existing wall that is
approximately 8ft tall by 14ft wide. The studs are 16" on center. From the "Existing Homes" page it appears that I
should order the "Slow rise" formula.
Is that correct? Thank
you for your help!!
Yes, the SR formula is the right
formula. On the website under ?Soundproofing? is more info on the
actual application. Calculations are simple enough once you understand
that the product numbers (II-100, II-200 & II-600 SR) correspond to
board foot (12?x 12? x 1?) coverage, i.e. II-100 yields 100 board
feet, II-200 yields 200 board feet and II-600 yields 600 board feet.
If you have an 8"x 14" foot
wall to drill and fill, multiply 8x14 to get the total square footage
(in this case = 112 sq. ft.) subtract any doors or windows and multiply
times the depth of the cavity. If we assume you have 3.5" 2x4s (most
aren't TRUE 2x4s, but actually 2"x 3.5"s) and there are no windows
or doors, you would multiply 112 times 3.5 which equals 392 board feet.
To fill the 8" x 14" foot
wall above, you would need 2 of the II-200 kits. This product is
significantly less expensive in the II-600 kit. For example, 2 of the
II-200 kits will cost $577.80 whereas one II-600 kit (30% more coverage)
only costs $695.00, in effect giving you the third II-200 for $30.85
because it?s all packaged in one kit. One 600 kit is yield equivalent
to 3 of the 200 kits.
Your energy savings will be very
significant. Any leftover material can be put into a lot of areas that
need attention. Sill plates in the basement or crawlspace, for
instance, where the basement or crawlspace walls meet the floor where
the floor joists lay on the wall.
I hope this answers your
questions and wish you a well-insulated day!

FOMO Foam II-605 fast rise kits
are perfect for insulating up under the floors. Please be sure to wear proper personal protective equipments in all applications. This spray
on Low Pressure Polyurethane foam is engineered to stick and can stick to your teeth
and facial hair. Wear proper safety protection.

coating of FOMO all around the basement wall cap will prevent air
infiltration and excess moisture buildup.
In existing homes, a small kit
will make a big difference!
Just 1" under the floor in your crawlspace or basement makes an absolutely
amazing difference in your comfort and energy savings. It will not fall
down like fiberglass batts. Ever. It is practically waterproof, so if you
get flooded it will protect your flooring from absorbing water and stop
water from coming in through the floor. Insects and critters can't nest in
it or chew through it. Your bathroom and kitchen tile floors will be warm
in the winter. It'll seal off your wall cavities from air being sucked up
into the wall cavities that contain fiberglass.
The spray on fast rise foam
formulas are excellent for smaller jobs like an addition to your home or
a shed or garage. Both are also available in E-84 Class 1 fire rated
