Radiant Barrier Coating
for energy conservation and heat & light reflection

LO/MIT Interior Radiation Control Coating Systems (IRCCS) are paints formulated to reduce building interior temperatures. They can be used in a wide variety of structures, from office buildings and warehouses, to factories, ice rinks and other arenas, pole barns, garages, storage buildings, tents and more. LO/MIT is a silver-colored, non-thickness dependent, low emissivity radiant barrier paint, which may be used in almost any application where infrared (heat) reflectivity or diffuse light reflectivity is required. Lower utility costs, increase comfort and lighting levels, improve output and lessen heat related health costs for livestock and poultry in agricultural applications by applying LO/MIT to the roof deck, rafters and un-insulated sidewalls. For all rooftop applications, please see Roofing. Because of their low thermal emissivity and high reflectivity characteristics, LO/MIT can reduce unwanted summer radiant heat gain in buildings and structures. Easily applied with standard airless paint sprayers, LO/MIT is the most economical way to retrofit a radiant heat barrier to an existing structure since it may be safely and quickly applied in enclosed areas at low cost and can easily replace foil or metalized plastic film radiant barriers.

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.

Emissivity (e) is a term used to describe the amount of heat objects release in the form of electromagnetic heat radiation. It is scaled from 0 to 1, and the closer the emissivity value is to 0 the less able the surface is to emit heat in that direction. Most roofing substrates have very high emissivities (e=0.850-0.930), allowing a vast majority of their heat to radiate to the cooler surfaces below, causing discomfort extending air conditioning run times. LO/MIT dramatically reduces the surface emissivity of the roofing substrate (LO/MIT-I MAX e=0.140, LO/MIT-I e=0.210, LO/MIT-II e=0.170, LO/MIT-II MAX e=0.150), drastically lowering the roof’s ability to radiate its heat inward, lowering interior temperatures by 10-25+ degrees F, all with negligible effects on exterior roofing materials. Because interior temperatures are now cooler, standard R-value insulations, air conditioning handling equipment and ductwork located in the attic will operate more efficiently. In addition, comfort is greatly increased and poultry and livestock in agricultural applications can produce more and will feel less heat related stress.

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

LO/MIT-II and LO/MIT-II MAX are recommended for all interior applications.

Applications that may involve some future abrasion, such as sidewalls or metal garage doors are excellent applications for LO/MIT-I or LO/MIT-II.

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 is inaccessible, LO/MIT can be used as a rooftop coating. Please contact the factory for assistance from one of our technical representatives.
