Reflective Roof Coating Applications

LOMITlogoeffectsENERGY STAR Radiant Barrier Roof Coating
for energy conservation and heat & light reflection

energy star logoLO/MIT-I is an ENERGY STAR certified radiant barrier roof coating that is formulated to reduce roofing surface temperatures at low cost. LO/MIT is a silver-colored, non-thickness dependent, low emissivity paint, which may be used in almost any application where infrared (heat) reflectivity or diffuse light reflectivity is required. It can be used on a wide variety of roofing substrates, from metals and rubbers, to stone, concrete, asphalt, some foams and more, no primer required in most cases. Help control interior temperatures, lower air conditioning loads, increase comfort and reduce heat-related stress on roofing materials easily with LO/MIT. LO/MIT’s extremely low film build can be installed for a fraction of the cost of other, thicker, rooftop coatings. SOLEC is proud to offer our customers products that have earned the government’s ENERGY STAR label.

Invented in 1978 by SOLEC for use in solar applications, LO/MIT went commercial by 1986 after research at the Florida Solar Energy Center (FSEC) showed its potential benefits for cooling buildings in warmer climates. Because of its low thermal emissivity and high reflectivity characteristics, LO/MIT is an ideal low-cost technology to reduce unwanted summer radiant heat gain in buildings and other structures. Just like low e windows, LO/MIT’s low e characteristics reflect radiant heat.

Testimonials

The resulting finish greatly increased the reflectivity of the roof and resulted in substantial roof temperature decreases. We measured skin temperatures under the roof coated with LO/MIT-I and those of an identical adjacent building that had not been coated. Temperatures under the roof coated with LO/MIT-I showed decreases in excess of 40F over the temperatures under the uncoated roof. We are quite satisfied with the LO/MIT-I and would recommend its use to other metal building owners.
James, AR
Our office has a built up tar and gravel roof of approximately 2950 square feet. Over the 12-month period immediately following the LO/MIT installation, we had an apparent savings of $724.00 on our electric bill, when compared to the previous 12 months.
Terry & Victor, FL
The black metal roof panel yielded a solar spectrum reflectance of 0.048 and an infrared emittance of 0.87. A single coat of LO/MIT on half of it yielded a solar spectrum reflectance of 0.829 and an infrared emittance of 0.20. That’s changing radiation properties significantly in a simple operation.
Tom, TN
The average indoor air temperature had been measured periodically over the past few months. It had been ranging from 89-109F. With the application of LO/MIT-I, we are now seeing temperatures approximately 80-99F. A dramatic reduction of indoor temps.
Steven, FL
As we had mentioned before, the LO/MIT-I reduced the surface temperature of the goodyear black rubber roof by 50+ degrees. While applying the LO/MIT-I product, we checked the surface temperature with an infrared non contact thermometer, and saw average readings on the untreated areas of 135 to 138 degrees. The areas we had already applied the LO/MIT-I were reading from 83 to 87 degrees.

LO/MIT Reflective Ballasted Roof 1

For exterior applications, high reflectivity is the major factor in reducing roofing skin temperatures. Highly reflective surfaces prevent sunlight from being absorbed by roofing materials, turning into heat. The cooler the roof skin temperature is, the less heat enters the building, and the cooler it feels inside. While there are many reflective roof coatings available, most require a thick film build for effectiveness. This increases the cost of material per square foot. LO/MIT requires only 1 mil (0.001in) wet film thickness (coverage of 400sqft/gal when spray applied) and therefore can be installed at a fraction of the cost of other roof coatings in far less installation time. It’s unique low emissivity properties also help to control the expansion/contraction process affecting the roof, reducing stress and increasing roof life.

LO/MIT-I is recommended for all exterior and roof top applications or projects that require extremely fast drying times.

The vast majority of the radiant heat gain in a building comes through the roof, however many structures can also benefit from having LO/MIT installed on sidewalls and garage doors. LO/MIT can also provide comfort to outboard structures like sheds, garages, barns and other storage buildings. In some cases where the undersurface of the roof is accessible, LO/MIT can be used as an interior radiation control coating system (IRCCS).
