A Thermaolastic Radiation Barrier
Sun's energy is a combination of visible light - 43%, infrared wavelengths -53%, that cause the most heating, and ultraviolet rays - 4%, has no heat associated with it. White and light colored paints and coatings reflect the visible portion of the light only. Assuming 100% efficiency the best they can do is reflect 43% (Fig. A) of the sun's energy. The greater amount of heat from the infrared rays continues beyond the coating and into our living and work areas.
According to the International Energy Agency, buildings currently account for as much as 40% of primary energy consumption.
The World Business Council for Sustainable Development reports that the carbon footprint of buildings exceeds that of all transportation sectors combined. Finding energy efficient chemistries and technologies to maintain temperature constants are a pressing issue. Liquiguard Technologies' latest innovation THERMORAD, a thermal radiation barrier coating, is the solution!
A Thermal Radiation Barrier - How Does It Work?
An object or surface that radiates (releases) all of its absorbed heat energy is called a "blackbody". The ratio between the energy radiated by an existing surface to the energy radiated by the blackbody is stated as the emissivity of that surface. The lower the
emissivity higher the R-Value (commonly understood as the insulation factor). Low-emissive paints increase the R-Value of the wall by changing the
heat transfer coefficient in a positive direction.
Common paints, including white coatings, absorb the unreflected portion of the sun's thermal energy and release it into the structure underneath. This in
turn heats our home and work areas that require cooling through the consumption of electrical energy. In cold climates the living and work spaces need
continuous heating because the generated heat is dissipated through the walls due to the lack of barrier properties in the paint.
FLEXTHERMACOAT use unique formulations and cutting edge raw materials that prevent the absorption of the thermal energy and reflect it back into the
atmosphere. When applied on inside walls they provide an insulating barrier preventing the heat or cold from being dissipated.
While consumers are concerned with both cost and environmental benefits derived from reduced energy consumption, they are not always willing to do
this by compromising their desire for aesthetics. Now THERMORAD allows them to have their "cake and eat it too".
It is capable of reflecting both the visible light and infrared radiation from the sun. It offers this feature in an unprecedented range of colors. With THERMORAD even black coatings can reach a reflection level greater than 25%, a substantial improvement over conventional black coatings that generally reflect 5 to 8% of the sun's energy. THERMORAD is a water based paint with the look and feel of conventional paints. It is applied just as any other paint product using the same tools and techniques. Its adhesion and water barrier properties are far superior to those of conventional paints. It is extremely fade resistant and has built-in mildew and algae barriers. The coating has no fumes, odors or other hazards.
