The ideal "cool" roof is one whose surface is minimally heated by the sun, such as a bright white roof. However, sometimes the term "cool" is applied to a roofing product whose surface is warmer than that of a bright white material, but still cooler than that of a comparable standard product. For example, the afternoon surface temperature of a specially designed "cool" red roof is higher than that of a bright white roof, but lower than that of a standard red roof. An example of a "hot" roof is one with a standard black surface, which grows very warm in the sun.
What makes a roof cool?
The most important feature of an ideal cool roof is that its surface strongly reflects sunlight. The surface of an ideal cool roof should also efficiently cool itself by emitting thermal radiation. Thus, a cool roof should have both high "solar reflectance" (ability to reflect sunlight, measured on a scale of 0 to 1) and high "thermal emittance" (ability to emit thermal radiation, also measured on a scale of 0 to 1). The solar reflectance and thermal emittance of a surface are called its "radiative" properties because they describe its abilities to reflect solar radiation and emit thermal radiation
What happens to sunlight reflected from a cool roof?
On a clear day about 80% of sunlight reflected from a horizontal roof will pass into space without warming the atmosphere or returning to Earth.
What is a "cool color"?
About half of all sunlight arrives in the invisible "near-infrared" spectrum. Standard lightcolored surfaces strongly reflect both visible and near-infrared sunlight, while standard dark colored surfaces reflect modestly in both spectra. Special dark and medium-colored surfaces that strongly reflect near-infrared sunlight are called "cool colors." The solar reflectance of a cool dark color can exceed that of a standard dark color by about 0.4.
Do Insulla roofs stay cool?
Over time, the deposition of airborne particles, the growth of microorganisms, and/or the oxidation of bare metal can reduce the solar reflectance of a cool roof. These events can also increase the thermal emittance of certain materials, especially those with bare metal surfaces. Eventually an equilibrium is reached between processes that soil the surface, such as particle deposition, and processes that clean the surface, such as wind and rain. Since the solar reflectance and thermal emittance of a outdoor surface typically reach steady values within one to three years, the "aged" solar reflectance and thermal emittance of a roofing product are measured after three years of natural exposure.
Are green roofs cool? What about thermally massive, super-insulated, and/or ventilated roofs?
There are a variety of roofing assembly technologies that can reduce the flow of heat into a building, including but not limited to solar-reflective, thermally emissive surfaces; vegetative cover (green roofing); thermally massive construction; super-insulation; and ventilation. We reserve the term "cool roof" to refer to one that stays cool in the sun by virtue of high solar reflectance and (preferably) high thermal emittance
Can I paint my roof white or a cool color?
There are specialized white elastomeric coatings available for low-sloped products and cool color polymer coatings available for tiles that can be sprayed on existing roofs as temporary solution.
What does a Insulla roof cost?
The price of a insulla roof is typically comparable to that of a standard (hot) roof of the same type, because coloration is responsible for a very small portion of the total installed cost of any roofing product.
What are the benefits of a insulla roof?
Selecting a insulla roof instead of a standard (hot) roof directly benefits the occupants of the building, and indirectly benefits the entire community. Installing a solar-reflective roof can also immediately slow global warming through a process called "global cooling."
Are your tiles resistant to any stain or spots?
Yes our tile will not water spot, stains due to smoke, grease. etc can be removed as long as they are cleaned on a regular basis.
Is your Tiles easy to clean?
Yes, you can power wash or use soap and water, a degreaser, etc to clean the tile(s).
Do your Roof tiles bow, bend or sag in humidity or warp like most do?
No, they can handle humidity with no problem.
Insulla Cool Roof tiles are impact damage resistant. So when someone has to work above the tiles due to a/c, plumping or electrical issues they cannot be damaged as with most others. Even when installing a percentage of normal tiles are list due to damages installing and of course when working above, Insulla will not have these issues.
What about UV?
Our Cool Roof tiles are 100% UV resistant.
What temperature can your tiles withstand?
Our Cool Roof tiles can withstand between 600 degrees centigrade.
What cost benefit is there to using your tiles over others?
Depending on the tiles you were going to use, in some cases ours will be cheaper, but, no matter what tiles you use ours will be much cheaper in the long run.
What are Acoustic Tiles?
Acoustical tiles are porous tiles (they have holes in them) and the holes are what help with reduction of noise in an area. But as soon as dust and dirt start to fill the holes the noise reduction is decreased and in time are not doing much more than a hard ceiling does for noise.
What about Bacteria, Mold and Mildew?
Our tiles have passed the ASTM test for Mold, they do not grow mold, bacteria or mildew.
What about Bio Blocks applied to acoustical tiles for Bacteria and Mold?
They work great for up to 25 years as long as they do not get wet, even moisture from A/C Condensation, Pipe Leaks, Roof Leaks. Which means bio blocks or chemicals added to help block bacteria, mold, etc are only good as long as the tile remains totally dry.
How difficult are your tiles to install?
They are extremely easy to install. They will fit into any standard 9" by 9" or 9" by 4.5" grid layout. You might have to cut to fit as you would with any tile. Ours only require a utility knife to score the tiles and then break away the unwanted area. You can cut them with a saw or hole saw.
