SEALECTION® 500 Frequently
1. What is SEALECTION® 500?
The SEALECTION® 500 spray foam is a complete insulation and
air barrier system that insulates and air seals walls, floors
and ceiling cavities against air movement, including spaces
around electrical outlets, baseboards, and where the walls
meet windows and doors etc. This means that outside air (hot
or cold) cannot seep through walls causing drafts or cold
spots. It also means that hot humid air cannot enter the walls
and condense on cold surfaces causing molds, mildew and
SEALECTION® 500 spray foam insulation is applied by qualified
trained installers, which provides a truly effective method to
construct energy efficient homes and buildings. The SEALECTION®
500 is a semi-rigid thermo-set polyurethane foam (see Product
Specifications), which is a cellular plastic composed of
millions of microscopic cells of which most are open. The
application of the product is done at the job site by
Certified Installers, providing a custom installation of the
insulation. The application technique and nature of SEALECTION®
500 make a perfect fit to all cavities irrespective of size or
By virtue of its low permeability to air, its adhesion to
other building materials, and its flexibility, SEALECTION® 500
becomes much more than just insulation. It provides superior
air leakage and sound control for residential construction.
SEALECTION® 500 is a one step insulation, and air barrier
system. SEALECTION® 500 eliminates the labor intensive work
associated with air-tightness detailing when insulating with
conventional insulation products.
Unlike "loose fill" insulation, which does not air seal the
building cavities. Air infiltration robs the insulation of its
R-value. The superior air sealing characteristics of The
SEALECTION® 500 System provides virtually the same R-Value in
the field as it does in the laboratory. Cold air in winter and
hot muggy air in summer cannot pass through our SEALECTION®
500 foam as it can through other insulating materials cheating
those products of its performing R-value.
2. What are the Advantages of SEALECTION® 500?
As well as simplifying the construction process for the
builder, SEALECTION® 500 Insulation eliminates the major
causes of building envelope problems, air-borne moisture
movement and entrapment. Blower door tests have shown that
steel framed homes insulated with SEALECTION® 500 Insulation
and with no polyethylene vapor barrier routinely measure under
the 1.5 ACH50 rating for the most energy efficient home.
Heating and cooling costs are typically reduced by 30 to 50%.
Smaller and less expensive heating and cooling equipment
(properly sized) can be used.
SEALECTION® 500 is inert and stable over a long term. It will
not settle or compact over time. It offers stable R-value and
is chemically and physically stable under normal conditions
between (-60�F and 180�F).
3. Does SEALECTION® 500 adhere to metal studs?
SEALECTION® 500 adheres well to steel studs and other natural
materials such as cement board, wood, etc. commonly found in
residential and light commercial construction. Since
SEALECTION® 500 will adhere to almost all surfaces in the
home, areas that do not require SEALECTION® 500 insulation
such as windows doors etc. must be protected from over-spray.
4. Are There any Compatibility Concerns with Other Building
SEALECTION® 500 is stable in the presence of most solvents
found in binders, bituminous materials, wood preservatives,
and sealers. It is resistant to facers containing
plasticizers, fuel, mineral oil, weak acid, and weak bases,
which are typically found in residential and light commercial
5. Any Electric Wiring Overheating Problems?
There is no special requirement need to encapsulate electrical
wires other than what is required with all types of
insulation. As with other types of insulation such as
fiberglass, cellulose when the properly rated size and type of
electrical wires are used, there is no over heating of those
6. Is the Insulation Corrosive to Metals?
No, SEALECTION® 500 Insulation is non-corrosive. It is
neutral, which means it is neither acidic nor alkaline. This
product will not cause corrosion to metal studs and other
metal typically found in construction.
7. Does the SEALECTION® 500 Insulation Support the Growth
No, SEALECTION® 500 Insulation offers no food value therefore
it cannot support bacteria or fungal growth. The effective air
sealing characteristics of SEALECTION® 500 prevents the
movement of hot air to the cold parts of the walls. This
effective air-sealing process prevents condensation from
taking place within the wall cavities. The elimination of
condensation within the wall assemblies prevents the growth of
8. What about pests i.e. roaches, ants, mice and termites?
SEALECTION® 500 insulation offers no food value, but it would
not present a sufficient barrier to their entry if they
decided to gnaw through it. Normally, pests take "the path of
least resistance" and if they cannot detect a food source then
they would normally not attempt to go through. In this sense,
SEALECTION® 500 acts as a physical barrier and an odor barrier
that has shown to significantly reduce the number of pests
entering the homes.
9. What are the acoustical properties of SEALECTION® 500?
SEALECTION® 500 Insulation has excellent sound absorption
properties and sound transmission properties. When comparing
SEALECTION® 500 to other insulations, there is a very
noteworthy difference. As an effective air seal, it eliminates
the air gaps through which sound travels easiest. SEALECTION®
500 Insulation is superior in controlling mid-range
frequencies that include the most common sounds, the human
voice and stereo music. For a 2"x6" wood cavity insulated with
SEALECTION® 500 the Noise Reduction Coefficient (NRC) is 75,
and Sound Transmission Coefficient (STC) is 39.
10. Does SEALECTION® 500 contain Urea Formaldehyde, CFC or
No, SEALECTION® 500 does not contain Urea Formaldehyde, CFC's
or HCFC's. This insulation is a semi-rigid urethane, open
cellular plastic foam, in which water is incorporated as the
sole blowing agent. SEALECTION® 500 has obtained the seal of
approval by the Environmental Choice Program of Canada
(equivalent to US-EPA).
11. Are there Health concerns with SEALECTION® 500?
No, SEALECTION® 500 is a "green" product. It meets off gassing
requirements of CGSB 51.23 92 for new residential
construction. No toxic or carcinogenic products were detected.
12. Does SEALECTION® 500 Break Down, Sag or Shrink?
No, SEALECTION® 500 Insulation is stable. It does not shrink
or sag. The reaction that created SEALECTION® 500 Insulation
is irreversible and it cannot break down into its constituent
13. Advantages of Semi-Flexible Foam?
SEALECTION® 500 remains flexible throughout the life of the
building. As the building expands and contracts with changes
of season and temperature, SEALECTION® 500 will move with the
changes without destroying the seal.
14. R-Value of SEALECTION® 500 Insulation?
The R-Values of SEALECTION® 500 Insulation is rated at R-3.8
per inch utilizing traditional R-Value calculation methods.
However, independent laboratory testing has proven that in a
�real-world� application where environmental conditions such
as wind are added, SEALECTION® 500 Insulation out performed
both fiberglass and cellulose insulations with R-values above
R-30. Therefore,SEALECTION® 500 has a �working� value of R-30,
15. Are These Aged Values?
Unlike foams filled with CFC or HCFC, the R-Value of
SEALECTION® 500 foam does not decline as it ages.
16. What is the R-Value of a SEALECTION® 500 Insulated Wall
R-Values of insulating materials are measured in laboratories
and are designated a nominal R-Value per inch. In the walls or
ceilings of building most factory-made insulation materials
suffer a reduction in performance due to air leakage and
infiltration. The insulating value of many building components
may be as low as 50% of the nominal R-Value of the insulation
they contain. By contrast, the insulation of a wall containing
SEALECTION® 500 Insulation will perform closely to that of the
laboratory tested R-Value of the material, and it seals the
wall cavity from air infiltration as well. The SEALECTION® 500
Insulation System is particularly suited for steel or wood
frame construction. SEALECTION® 500 expands 120:1 as it is
installed, adhering to surrounding building components. It
completely seals joints, crevices and voids, including
difficult-to-insulate spaces such as steel stud "U" and "C"
sections, double studs, and non-standard stud locations.
17. At What Stage is SEALECTION® 500 System Installed?
The SEALECTION® 500 Insulation System is installed after the
windows, doors and roof are in, the electrical and plumbing
inspections are completed, and after any other electrical or
mechanical system located behind the drywall is installed. It
is the last installation to take place before drywall is
18. Can SEALECTION® 500 be applied in an Existing Wall?
We do not recommend that SEALECTION® 500 be applied in
existing walls. However, we have had good results in using
SEALECTION® 500 in the attic and in the crawl space (if
applicable) without disturbing the walls in a retrofit
application. The reason is that a large portion of your energy
loss is caused by the "chimney effect" - hot air rises
therefore creating air movement within a house. If you cap off
or seal the attic (the chimney) with SEALECTION® 500 you have
greatly cut down on air movement within the house and wall
assemblies, and therefore have lowered your existing walls,
which do not contain insulation.
19. Are other trades (workers) allowed in the general area
of the application of SEALECTION® 500?
SEALECTION® 500 shall be installed on site by qualified
installers trained in the proper safety and handling of the
chemicals. Other trades persons should be kept away from the
immediate area where spraying is conducted.
20. Is it possible for the "Do-it-Yourself" homeowner to
install spray in foam?
SEALECTION® 500 Insulation has to be installed by a certified
contractor with specialized proportioning equipment. The
installer has been trained to work with the chemicals involved
and has also been trained in a building science to provide the
best installation possible.
21. How much does SEALECTION® 500 system cost?
SEALECTION® 500 is considered to be more expensive than most
conventional insulation, however SEALECTION® 500 cannot be
compared to conventional insulation. When using the SEALECTION®
500 foam insulation system it actually air seals the building
end eliminates energy robbing air leakage and the associated
problems with moisture, mold and mildew and condensation
problems inside the walls. When calculating the actual cost
you need to consider the possible need to downsize the HVAC
systems, eliminate building wraps, and eliminate a significant
portion of the material and labor costs associated with an air
It is erroneous to compare the cost of loose fill insulation
to that of SEALECTION® 500 spray foam insulation system. The
invested premium to upgrade from standard fiberglass is an
insignificant part of the overall cost of a home and your
long-term energy costs. When you are planning to install an
upgraded insulation package, remember that the SEALECTION® 500
is more expensive but it provides you with the best
performance and comfort value. The additional upfront costs
typically pay for themselves in energy savings within three
years and will keep on saving you money every year thereafter.
Your builder wants you to build the very best house, be
patient and persistent if he is unfamiliar with our product,
but ask for the product by name, SEALECTION® 500.
