How does CoEm-Tek coatings
compare with “traditional” insulation? |
| |
Traditional insulation is meant to be mass insulation for protection
against heat transferred by conduction (see explanation of Heat Transfer
Mechanisms). CoEm-Tek coatings on the other hand prevents heat transfer
by radiation. Traditional insulation and radiant barriers have value
and one does not necessarily replace the other. In many cases radiation
control coatings compliment traditional mass insulation.
Traditional insulation is typically installed on the underside
of roofs, or inside the walls of buildings. As the outside temperature
warms the roof or wall the heat is absorbed into the mass insulation.
Once the mass insulation is saturated it re-radiates that heat back
into the building. CoEm-Tek coatings keep 85% of the heat from solar
radiation from ever getting into the roof because of its high solar
reflectivity. The 15% that is absorbed by the coating is quickly
dissipated through the ceramic particles by the products high rate
of emissivity.

| 3. |
Why is it that CoEm-Tek
coatings have such high solar reflectivity values? |
| |
CoEm-Tek coatings are formulated with not only Titanium Dioxide, but
with a mixture of “trade secret” pigments, which actually
enhance the reflective values. |
| |
|
| 4. |
What is the R-value of
your ceramic products, and how do these values compare with mass insulation?
|
| |
There are no R-Values yet for liquid coatings, but they can produce
an insulation equivalent of up to R-12, and when used on exterior
roofs and walls, using our standard white color we can achieve equivalent
R-values of up to R-20 because of the high reflective values of the
coatings. |

| 5. |
Can you prove that your
products will actually reduce my energy costs and save me money? |
| |
Yes, we have software that we use to perform energy calculations to
show the energy savings and potential payback of the cost to install
the products. For large installations, we can have an engineering
company perform an energy audit on the building showing energy savings
and paybacks. |

|
| 6. |
If CoEm-Tek’s coatings
keeps the heat out during the summer, will it keep the heat in during
the winter? |
| |
CoEm-Tek’s ceramic coatings are much more effective at keeping
the heat out in the summer, but will, to a lesser degree, keep the
heat in during the winter. The same principles apply, the coating
acts as a radiant barrier keeping heat from being absorbed by the
walls and ceiling, but the results are less noticeable then when trying
to keep heat out. |

|
| 7. |
What surfaces need special preparation? |
| |
All surfaces must be clean and dry. Rust must be treated. See product
data sheets for additional information. |
| |
|
| 8. |
What is the impact of color on the
reflectivity on CoEm-Tek’s ceramic coatings? |
| |
CoEm-Tek’s standard bright white color is the most efficient,
when colour is added the reflectivity will decrease slightly. |
| |
|
| 9. |
Will CoEm-Tek’s ceramic coatings
provide additional insulation value if the dry film thickness is increased? |
| |
Yes, but will be cost effective with 2 or 3 coats, the added insulation
value will be cost prohibitive after 25 to 30 mils of dry film thickness
is reached. |
| |
|
| 10. |
What is the average shelf
life for CoEm-Tek coatings? |
| |
The maximum shelf life is typically one year. We have found many of
our products to be stable, if not opened, for up to three years. CoEm-Tek
Coatings uses one of the highest quality of in-can-perservatives available
on the market.
|
| |
|
| 11. |
What is the temperature
range of service for CoEm-Tek coatings? |
| |
CoEm-Tek coatings will perform at most any temperature, but we find
that the products perform the best at temperatures above 26ºC
(80ºF) but not to exceed 177ºC (350ºF). |
| |
|
| 12. |
What kind of training
or certification does CoEm-Tek provide? |
| |
We offer a one-day course covering the theory and application of the
product for those companies interested in being a Certified CoEm-Tek
Applicator. The training can be provided here in Heidelberg, Ontario
or at your location.
|
| |
|
| 13. |
What kind of warranty
is offered on your products? |
| |
When the products are applied according to our specifications we will
provide a 10 Year Limited Warranty on the product. With the coatings
durability and resistance to UV light it should last much longer then
the 10 years though. |
