Using radiant barrier insulation in your attic is paramount to creating a more comfortable and energy efficient home, keeping you cooler in summer and warmer in winter.

By properly installing a radiant barrier in your attic, you can lower your air conditioning and heating bills and can potentially extend the life of your equipment.

Radiant barrier or reflective insulation is an absolute must in warmer climates. The aluminum foil material used in reflective insulation reduces radiant heat transfer through the attic by 97%. Installing a radiant barrier as attic insulation in the attic ceiling means that the heat of the sun will be reflected back out of your attic instead of crossing the airspace to be absorbed by the insulation on the attic floor and then radiated down into your home below. Similarly, adding an attic radiant barrier can reducing the loss of heat from the attic floor to the roof sheathing in cold weather by reflecting attic heat downward.

Radiant barrier foil insulation is unlike mass insulation that merely slows down or resists heat transfer. A radiant barrier BLOCKS radiant heat. Heat always moves to colder areas by natural law - the problem is how to keep the heat in the winter and how to keep it out in the summer.

There are three ways in which heat moves from warm spaces to cold spaces: CONDUCTION is the direct heat flow through a solid object such as a wall or a ceiling. CONVECTION is heat movement through air, occurring when air is warmed. The warm expands, becoming less dense and rising.

RADIATION is the movement of heat rays across air spaces from one warm object to a cooler object. The heat we feel from a wood stove or a quartz space heater is radiant heat. ALL OBJECTS AND BODIES GIVE OFF RADIANT HEAT.

HeatBloc-75 radiant barrier coating is a water-based, low emissivity (low-e) product and an excellent replacement for foil or metallized plastic film radiant barriers. In many situations, HeatBloc-75 is the only economical way to retrofit a radiant barrier since it may be safely applied in enclosed areas at a low cost.

With a radiant barrier properly installed, you can significantly reduce the amount of heat that common insulation materials are designed to slow down thereby maximizing the efficiency of common insulation materials making your home more comfortable and reducing your overall energy utility costs.

Radiant energy is energy that comes in waves from the sun or comes from an inside source, like a furnace. On warm days, when the sun’s rays strike the roof, the roof absorbs heat, which increases temperatures in the attic. Eventually, this heat is transferred throughout your home – resulting in increased air conditioning costs. On cool days, when radiant energy comes from an inside source, it travels upward and escapes through the attic. But in either situation, energy costs are literally going through the roof.
 

Features of Radiant Barrier

• Low emissivity, high reflectivity

• Permeable, does not trap moisture

• Easily installed using standard airless or air atomization spray equipment or rollers

• Does not block cellular or antennae signals as can occur with foil products

• One operator can easily install 1000 ft.²/hour using a spray rig

• Excellent investment, normally saves 8-12% of AC costs, improves comfort levels

• Improves efficiency of existing insulation

• Only economical way to retrofit radiant barrier to existing structures

SPRAY APPLIED RADIANT BARRIER

This high-technology energy-saving product, which is engineered to be professionally spray-applied to the underside of a home’s uncoated roof deck, contains microscopic reflective particles that help keep radiant energy from transferring in or out of a home. That means your rooms stay cooler in warmer weather, and warmer in cooler weather – an increase in thermal comfort that you’ll definitely appreciate.
