CONTROL RADIANT HEAT. PROTECT YOUR BUILDING.
Large commercial and industrial buildings can absorb enormous amounts of solar energy through their roofs and exterior surfaces. Metal warehouses, shops, storage facilities, and other large structures can become extremely hot long before the workday is over.
Area 361 Radiant Defense provides professional spray-applied radiant barrier systems designed to reduce unwanted radiant heat transfer and help create a more manageable interior environment.
Our systems can be applied to existing buildings as well as new construction, depending on the substrate and application.
A commercial roof exposed to direct sunlight can become significantly hotter than the space below it.
That heat is transferred through the building by conduction, convection, and radiation. Radiant barrier systems specifically address the radiant component of heat transfer.

BUILDING INTERIOR
RADIANT DEFENSE creates a low-emissivity, reflective surface that helps reduce radiant heat transfer from the heated roof toward cooler interior surfaces.
Potential interior temperature reductions of approximately 10–25°F+, depending on building characteristics and conditions.
Results vary based on building design, climate, roof material, insulation, ventilation, HVAC systems, application, and other conditions.
Our commercial applications can include:
WAREHOUSES
Large roof areas can create significant heat loads. Radiant Defense can help reduce radiant heat entering occupied or storage areas.
MANUFACTURING FACILITIES
Help create a more manageable environment for employees and equipment in large industrial spaces.
METAL BUILDINGS
Metal roofs and walls exposed to direct sunlight can absorb substantial heat. Appropriate interior or exterior applications can help address that heat load.
COMMERCIAL SHOPS
Automotive shops, fabrication facilities, repair shops, and maintenance buildings can benefit from reducing radiant heat from overhead surfaces.
STORAGE FACILITIES
Help reduce heat transfer in storage buildings where maintaining a more moderate interior environment is important.
DISTRIBUTION & LOGISTICS
Large roof decks and loading areas can contribute significant heat gain. Radiant barrier applications can help address these high-exposure surfaces.
GARAGES & VEHICLE FACILITIES
Help reduce radiant heat from roofs and, where appropriate, exposed metal walls and doors.
OFFICE & OCCUPIED SPACES
For buildings with offices beneath or adjacent to hot roof areas, reducing radiant heat can improve comfort and potentially reduce cooling demand.
ARENAS & LARGE-SPAN STRUCTURES
Radiant barrier coatings can be used on appropriate large-span roof decking and interior surfaces. The manufacturer documents commercial applications including arenas and ice rinks.
RETROFIT YOUR EXISTING STRUCTURE
One of the biggest advantages of a spray-applied radiant barrier is the ability to treat an existing building.
Depending on the structure, the coating can be applied to accessible interior roof decking, rafters, sidewalls, or appropriate exterior roofing surfaces.
This can provide an alternative to installing traditional foil-type radiant barriers, particularly where installing a separate membrane would be difficult.
NO MAJOR REBUILD REQUIRED
We evaluate the existing structure and determine whether the accessible surfaces are appropriate for application.
For buildings where the underside of the roof is accessible, radiant barrier coating can be applied directly to appropriate interior surfaces.
COMMON INTERIOR SURFACES
Metal Roof Decking
Plywood
OSB
Rafters
Uninsulated Sidewalls
Gable Ends
Interior Metal Panels
Certain Ceiling Surfaces
Wood, plasterboard, painted metal roof decking and other common building materials with potential substrates, provided they are appropriately prepared and compatible.
When the underside of a roof isn’t accessible—or when the goal is to address solar heat at the roof itself—an exterior radiant barrier roof coating may be appropriate.
POTENTIAL ROOF TYPES INCLUDE:
METAL ROOFS
Galvanized steel
Galvalume
Painted metal
Other compatible metal roofing
LOW-SLOPE / FLAT ROOFS
Built-up roofing
Modified bitumen
Tar & gravel
EPDM/rubber
Certain single-ply systems
OTHER ROOFING SYSTEMS
Asphalt-based roofing
Certain foam roofs
Other compatible roofing substrates
Our product can be used on a broad range of exterior roofing substrates, with compatibility evaluation recommended for certain materials such as foam and existing coatings.
COMFORT
Reducing radiant heat from overhead surfaces can make occupied spaces more comfortable.
COOLING LOAD
A lower interior heat load may reduce the amount of work required from air-conditioning systems.
The manufacturer reports potential A/C savings of up to 15% or more in some applications, but actual savings vary significantly by building and operating conditions.
EXISTING INSULATION
Radiant barrier and insulation address different heat-transfer mechanisms. A radiant barrier can complement existing insulation rather than requiring its removal.
ROOF PROTECTION
For exterior applications, high reflectivity can reduce roof-skin temperatures, while low emissivity can reduce the rate at which the roof radiates heat toward the interior. The manufacturer states this combination can reduce thermal expansion/contraction stress.
RETROFIT POTENTIAL
An existing building may be treated without replacing the entire roof system, provided the substrate and condition are appropriate.
RADIANT BARRIER IS NOT INSULATION - THEY DO DIFFERENT JOBS.
INSULATION
Primarily slows conductive and convective heat transfer.
RADIANT BARRIER
Targets radiant heat transfer across an airspace.
That means Radiant Defense can be used alongside an existing insulation system as part of a broader building heat-management strategy.
Radiant barriers do not have a conventional R-value; R-value applies to insulation systems that address other modes of heat transfer.
