Insulation vs Standard Insulations
Over the past 50 years when you thought of insulation it was a
The only considerations were, do I use Fiberglass or Cellulose
and what R-Value did I need in my walls and attic? No one
really gave much thought to insulation during the design of
the home/office or the construction process. For 50 years
there were NO REAL BIG improvements in the insulation
industry, so Builders and Architects became comfortable with
consistently using one or the other for all their structures.
However, during the past decade a MAJOR IMPROVEMENT in
insulation arrived in our industry. LIQUID SPRAY FOAM!! It
wasnít just a little better than the conventional insulations
used for half a century, liquid spray foam insulated homes and
businesses DRAMATICALLY BETTER! Spray foam insulations also
offered BIG improvements
In many other areas as well. Just look at many of the
Spray foams cut monthly air
conditioning/heating costs up to 60%
Foams improve indoor air
quality (reducing allergy & asthma attacks)
Spray foams help homes &
businesses become much quieter
Foam insulation will not
support or spread flame
Spray foam kills mold on
contact and reduces future mold growth
Foam insulation is not a
food source for mold, roaches, or termites
Foam insulation is not
damaged by water or floods
Spray foam does not settle
or pack down over time
Foam insulation will not
sag or split as it ages
Spray foam does not allow
air loss or air infiltration into your home
Now my biggest challenge is
to help construction professionals understand that, SPRAY FOAM
AND STANDARD INSULATIONS ARE NOT EQUAL!!
For the past 5 decades it didnít matter where you bought
fiberglass or cellulose it was all the same quality and same
R-Values. Heck, many homeowners just went down to Home Depot
or Lowes, grabbed a truck load and insulated their homes
themselves. Again, there were no real decisions to evaluate
when it came to insulating your home or business.
Weíve learned in the foam industry that we canít trust
R-Values either. Because the old out dated thermal resistance
tests are inaccurate. They arenít even close to being correct.
Those old R-Value tests only measure one type of heat -
Conduction Heat. What we use in our foam industry are
Performance Value Tests. These tests measure all 3 types of
heats: conduction heat, convection heat, and radiant heat from
the Sun. These Performance tests have proved that the real
thermal resistance value (R-value) of standard insulation is
very inaccurate. As much as a 60% decrease in their true
An R-15 fiberglass batt actually performs like an R-9. An R-30
fiberglass batt performs like an R-19. Blown insulations like
fiberglass, cellulose and rock wool have even lower R-values.
To meet code requirements today our attics must have a minimum
of an R-30 insulation, and because blown insulations are so
much cheaper than Batt insulation, all to often it is the
insulation of choice. But blown insulations perform the worst
in Performance Tests. In Performance Testing 3 Ĺ inches of our
Open Cell Foam, which has an R-value of 13, easily out
performed 12 inches of blown Fiberglass an Cellulose which is
Years ago when the tests were first conducted, many Builders
and Architects were left scratching their heads in confusion.
How can this be? Well itís simple. Old standard insulations
allow a lot of airflow through them. So the air loss and air
infiltration in our homes and buildings was very high, which
is why our utility bills have been much higher than necessary.
Foam insulation does not allow air to flow so freely through,
which makes it a superior insulation material. Stopping
unnecessary air flow helps homes become much more efficient.
Our company receives calls every month from homeowners who ask
why their utility bills are so high, even though they thought
they had insulated their home with the best fiberglass,
cellulose or rock wool insulation on the market today. We also
get calls from builders and architects asking why some of
their office buildings and homes are performing so poorly.
They spend a fortune upgrading air condition systems,
installing heat reflectant roof materials, sun blocking films
on east/west windows, etc. and none of these products solve
their high utility bill problems. None of these problems
without solving the air flow problem.
Every time we go out to evaluate a home or office building we
find the same thing. The house or office was insulated with
standard insulations that are not blocking enough heat and
humidity from entering the home/office. Sadly, we canít fix
the insulation in their walls because they are sheet rocked
and there is nothing we can do to replace the insulation. So,
we foam their roof decks and block the radiant heat from the
sun which solves some of their energy problems.
The bottom line is this: There are some things in your new
construction that you can buy a lower grade of material and
still be O.K. However, insulation is not one of them. We canít
solve or fix insulation problems in your walls after they are
sheet rocked. You will live with that costly mistake forever,
paying much higher monthly utility bills and having rooms of
your house that are uncomfortable. So, PLEASE BE CAREFUL. Do
not buy the cheapest insulations or accept the cheapest bid.
