Q & A
Q: How is CBF an effective
insulation under concrete?
A:
In order for reflective insulation to perform effectively there must
be an airspace on at least one side of the foil. This is why CBF
has the foil sandwiched between two layers of polyethylene
bubbles; the bubbles provide the foil with 3/16" airspace on
both
sides,
thus allowing the 99.9% pure aluminum foil to reflect the radiant heat
waves in the desired direction.
Q: How much of the
heat loss in a Radiant
Heated Slab is Radiant?
A: Increases in temperature differences (Delta T) will
increase the
radiant component of heat loss. As the slab increases in
temperature
so will the amount of radiant heat emitted by the slab. CBF
provides an airspace on both sides of the foil, allowing
it to reflect 57% of the radiant heat waves and will reduce heat loss
by
85%.
Q: Will the bubbles
burst from the pressure
of the concrete?
A: CBF was tested using the ASTM 1621-94 Compression
Test Method. CBF tested at over 140psi
with no
bursting of the bubbles. The amount of pressure under a four-inch
slab of concrete is less than one pound per square inch. The
deflection
of CBF with a load of one pound per square inch was
less then 10%.
Q: What is
the R-Value of CBF ?
A: R-Values are a measure of thermal resistance to heat transfer
caused
mainly by conduction and convection, but do not fully measure a
product's
ability to reflect radiant heat energy. Using the ASTM C236
(modified)
Test Method in a vertical position CBF was measured
as an R-4. R-Values however do not take into account the full
reflective
value of CBF. CBF has been
tested and proven to reflect 57% of the radiant heat waves using the
ASTM
C518 Standard Emissivity Standard Test Method.
Q: Is CBF a vapor
barrier?
A: CBF does not only have a high insulation value,
but it is also an excellent vapor, radon and methane barrier.
Unlike
foam board insulation CBF does not require an additional
vapor barrier. CBF was tested using ASTM E 96-93,
Standard Test Method for Water Vapor Transmission. The results of
the test revealed that the CBF exhibited a high level
of vapor resistance with a perm rating of <0.02.
Q: Does the concrete
deteriorate CBF ?
A: NO. The aluminum foil in CBF is
sandwiched between two
layers of polyethylene bubbles, which protects the foil from the
chemicals
in the concrete and from any lime or other contaminants that may come
in
contact with the CBF from the soil. The bubbles protecting
the
foil and providing airspace are comprised of linear low-density
polyethylene
material. Low-density polyethylene has a high environmental
stress
resistance. The chemicals in concrete and the soil will not deteriorate
the polyethylene bubbles due to the strong physical properties of the
material.
