Spray CoatingCool Roof coatings have steadily become a more popular form of protection against the elements over the last few years, mainly because Cool Roofs can deliver high solar reflectance and high thermal emittance (the ability to radiate absorbed or non-reflected solar energy). These systems can be sprayed on or rolled on to your roof like most paint. These acrylic elastomeric or silicone based coating can be much ticker and full bodied than your normal paint and deliver performance that will definitely outperform your everyday standard paint products. These systems can be used in conjunction with cold applied liquid emulsion and fiberglass matting to provide a complete roofing system without the need for old roof removal.
During AfterPROS: Less than half the price of a complete new BUR roof, provides you with a warranty close to that of most basic built up roof systems, extend the roof service life and achieve cooling energy savings in hot summers. No roof removal required, less debris, no smell of tar, no direct flames on the roof. Easy and fast application.
CONS: Without a proper maintenance program to keep the material clean, the energy savings of cool roofs can diminish over time. They are thin and do not as long lasting as a BUR (built up roofing system). In open beam homes or structures with no attic space or insulation, they can make for a colder winter. They have to be re-coated every 8-12 years.
Therma SheetLOW-E Reflective Insulation
Products are manufactured by using both post-consumer and new materials, and can be incorporated throughout all facets of the building industry. The insulation can be used as a “stand alone” product, or in conjunction with mass insulation’s to create greater R-Values.
Manufactured from non-porous material composed of air trapped in tiny closed cells, providing for an excellent thermal break and vapor barrier – in one single insulation.
When used with a mass insulation system, the addition of LOW-E Reflective Insulation will increase insulation system performance, by helping to achieve ASHREA 90.1 and LEED building envelope requirements.
Green Building Advantages
LOW-E meets “Green Building” standards by increasing the thermal efficiency of the building envelope. Refer to the LEED rating system for individual products and applications.
Thermal Performance of a Hybrid Metal Building Insulation Assembly
A metal building insulation assembly produced by Environmentally Safe Products was tested in accordance with ASTM C 1363 in the Large Scale Climate Simulator at the Oak Ridge National Laboratory. This hybrid system consisted of conventional fiberglass blanket insulation with ESP reflective insulation installed above the blanket insulation to form two reflective air spaces between the blanket insulation and the panels of a standing seam roof.
