Passive Energy Conservation - Greener Solutions
When the sun shines, its radiant heat (radiant solar energy) is automatically absorbed by the roof and walls. This energy then passes on to the interior, heating up the inside of the homes and buildings. To counteract this thermal heat transfer, a protection barrier has to be implemented in the roof and wall systems. Thermo-Brite serves this purpose best. Due to its superior constitution, Parsec Thermo-Brite is able to perform its task creditably. When installed, the highly reflectively surface can repel 95% of the solar heat, while the fortified backing is strong enough to withstand stretching and elongating.
With tear-resistant properties, it is not easily damaged on site, thereby facilitating installation. The strength of the material permits it to be spread across purlins or rafters without the aid of netting. The use of PARSEC Thermo-Brite also saves on labour costs through the use of a product that serves as roof decking and radiant barrier in one, without the need for conventional roof mesh.
Besides its principal role of being radiant barrier, PARSEC Themo-Brite also acts as a water barrier to roof leakage when used in both metal and tile roofs. The extremely low water vapour transmission rate due to the reinforced barrier properties proves useful in the case of insulating air-conditioning ducts and chilled water pipes, where condensation inside the articles is fatal. This remarkably low permeability to the passage of moisture and gases is critical in cold climatic conditions.
According to a 2010 study by the Building Envelope Research Program of the Oak Ridge National Laboratory, homes with air-conditioning duct work in the attic in the hottest climate zones, such as in the US Deep South, could benefit the most from radiant barrier interventions, with visible annual utility bill savings. It is also believed that radiant barriers such as PARSEC Thermo-Brite also help to improve comfort and to reduce the peak air-conditioning (or heating) load of a given building.
