1. How does CORBONDŽ II work?
The purpose of buildings for people is to isolate them
comfortably from a hostile exterior climate. The purpose of
insulation is to develop this climate isolation beyond the
minimum to allow complete modern interior climate control.
To achieve this climate isolation successfully requires
isolation between interior and exterior air and moisture and
the system must be reversible so the building may be both
heated and cooled efficiently. By its solid cellular
plastic, fully adhered in place nature, CORBONDŽ II achieves
the climate isolation necessary in the thin space of the
building cavity. Exterior and interior climates cannot mix
so no compromise of climate isolation can occur due to the
exterior climate.
2. Does CORBONDŽ II need venting like conventional fibrous
insulations?
No. CORBONDŽ II does not need venting. Venting was
designed to carry moisture out of fibrous insulation so it
can maintain its thermal efficiency by trapping dry air.
With CORBONDŽ II, no air can enter into or through the
product, as it is a solid cellular foam. Since no air or
moisture can get in or around it, it need not be vented off.
3. How does CORBONDŽ II control moisture movement and
condensation?
Most damaging moisture within a building envelope cavity is
the result of warm moist inside air being exchanged with the
cold dry air inside an insulation cavity. As the moisture in
the air condenses, it forms dew and/or frost within the
insulation. Because CORBONDŽ II does not allow the movement
or exchange of air within the cavity, this moisture movement
and condensation does not occur. CORBONDŽ II is ideal for
use in climates where buildings are both heated and air
conditioned because the situation is reversed in summer with
moisture forming on the back of the interior vapor retarder.
4. Does CORBONDŽ II contain formaldehyde?
No. Spray-in-place polyurethane insulation, and particularly
CORBONDŽ II does not contain formaldehyde resins. CORBONDŽis
made of resins similar to popular polyurethane varnishes for
wood. |
5. At what point of construction is CORBONDŽ II sprayed into
place?
CORBONDŽ II is applied before the sheet rock is put in place
but after plumbers and electricians have completed rough-in
work. The spray-in-place product creates a bedding around
the pipes and closes all penetrations in and through the
exterior walls of the structure which completes a nearly
monolithic insulating blanket. CORBONDŽ II can be installed
quickly even in extreme weather conditions. An average house
of 1300 square feet may take a trained crew 5 to 6 hours to
complete.
6. Is CORBONDŽ II environmentally friendly?
Yes! CORBONDŽ II II product uses a new generation of
environmentally friendly ingredients. CORBONDŽ II now
contains no CFC's. Also, its superior insulating
capabilities dramatically reduce heating and cooling
demands, reducing harmful emissions from power plants and
home heating units.
7. What happens if the owners want to add an electrical outlet
once CORBONDŽ II is installed?
If an outlet must be added, CORBONDŽ II drills more easily
than wood. There is also typically a small space left
between the wall board and the CORBONDŽ II so a wire can
slide through.
8. Can you drill holes in existing walls and fill them with
CORBONDŽ II?
No. When CORBONDŽ II expands it is very strong. As a result
it may distort a closed wall cavity and then set up hard.
CORBONDŽ II is always sprayed into an open cavity. This also
allows for better job quality control because the technician
can see what is being insulated.
9. How long does CORBONDŽ II last?
Indefinitely. As an inert, long lasting polymer plastic, a
house wall or commercial structure is the perfect place for
CORBONDŽ II to do its job for a long time. |
