THERMO-SHIELD® ROOF COATS
DESCRIPTION
THERMO-SHIELD® Roof Coats are highly efficient, energy-saving, flexible coatings, made from a water-based pure acrylic resin system filled with vacuumed sodium borosilicate ceramic micro spheres of less than 100 microns in size. Each micro sphere acts as a sealed cell and the entire mastic acts as a thermally efficient blanket covering the entire structure. These coatings are non-toxic, friendly to the environment, and form a monolithic (seamless) membrane that bridges hairline cracks. They are completely washable and resist many harsh chemicals. THERMO-SHIELD® Roof Coats have high reflectance and high emittance as well as a very low conductivity value. THERMO-SHIELD® Roof Coats greatly reduce thermal shock and heat penetration by keeping roof surfaces much cooler in hot summer weather. They offer UV protection and low VOC's. They display excellent dirt pick-up resistance and retain their flexibility after aging. THERMO-SHIELD® Roof Coats reduce noise transmission and have an effective use range from -40 Deg C (-40 Deg F) to 375 Deg C (700 Deg F).
INSULATION
Although these Roof Coats enjoy very low Conductance (0.05 W/mK), it is the combination of their high Reflectance (82%), high Emittance (94%) and Endothermic Effect® what makes them a very good choice for protecting your roofs from heat buildup. Unlike typical mass insulation, where heat conduction is just slowed down, this technology keeps the heat out. Sun light only produces heat when it is absorbed by the roof surface, and being able to keep heat from forming into the surface of the roof is a very effective way to insulate. The cooling process of Endothermic Effect® ensures that the surface continues to insulate, even if Reflectance is diminished with aging, dust build-up or darker colors
ADHESION
Excellent adhesion to a wide variety of substrates: wood, urethane foam, galvanized steel, aluminum, asphalt roof shingles, concrete, asbestos and others.
VARIABLE PERMEABILITY
This feature, unique to THERMO-SHIELD®, allows the membrane to perform unlike any other coating. When conditions are dry, the polymers shrink and open pores to allow trapped water vapor to breathe out of the substrate, but when conditions are wet (raining, ponding of water, etc.), the polymers swell, close the pores, and the entire membrane becomes watertight.
THERMO-SHIELD® is a charter member of the U.S. Government Energy Star Roof Program. The U.S. Department of Energy (DOE) and the Environmental Protection Agency (EPA) state the following benefits are derived from the use of reflective coatings:
- Can save 40% a year on Electric Bill
- Provides superb noise reduction
- Is an affordable alternative to convention insulation
- Offers extreme interior and exterior fire & chemical resistant
- Waterproofs
- Doesn’t harden, chip, crack or become chalky
- Provides Variable Permeability-Adapts to changing weather conditions
- Withstands wind abrasion, hail, volcanic ash and other caustic airborne pollutants
- Easy to clean and low maintenance
- Non-Toxic in its cured and liquid forms
- Mildew and Mold resistant
- Performs under extreme temperatures
- Certifications and approvals
