Radiant Barrier Insulation

radiant barrier insulation

A radiant barrier reflects/blocks radiant heat energy instead of trying to absorb it. A radiant barrier also REDUCES convective heat transfer by acting as a physical blockade against convective loop air flow.

A radiant barrier is a breathable, 97% reflective, reinforced metalized film that reflects and blocks the source of heat keeping it out during the summer and retaining the heat during the winter. Radiant barriers were developed by NASA to protect spacecraft and astronauts against the extreme elements of space. It is unaffected by humidity and will continue to perform at a constant level no matter how humid.

Radiant barriers do not absorb heat like mass insulation (fiberglass, cellulose, spray foam, etc). Instead, RB’s reflect 97% of the heat that hits their surfaces and therefore, have no “R” value rating. ITS NOT THE “R” VALUE THATS IMPORTANT WITH THIS MATERIAL, ITS HOW IT REFLECTS RADIANT HEAT AWAY FROM ITS SURFACE!!!

Double Bubble Foil Insulation

double buble foil

A double sided 97% reflective layer of foil sandwiched between two layers of durable nylon bubble material (1/4″) thick that holds a high “R” value (depending upon the application) and will hold its true value from -60deg to 180deg F. It is unaffected by moisture, humidity and mold. Its Insulating and reflective properties far outweigh the “R” values of other types of insulation in such a thin material.

HEAT 101: HOW HEAT WORKS AND IS TRANSFERRED

Conduction: The transfer of heat flowing through a substance (molecular motion) or to another touching substance. If you touch a pot on the stove, the heat is transferred from the pot to your hand via conductive heat transfer.

Convection: The transfer of heat in fluids, such as rising heated air, steam, and moisture. If you put your hand above a boiling pot, you will feel heat rising from the pot in the form of steam. This transfer of heat from the pot upwards is via convective heat transfer. Convective heat transfer results in warmer air rising and cooler air settling creating a convection loop termed free convection. A Convection loop can also be generated mechanically with the aid of fan or wind and is then called forced convection.

Radiation: The transfer of heat via long wave infrared radiation rays that are invisible to the naked eye and unaffected by air currents. If you step outside on a windy sunny day, you will feel the sun’s heat rays on your face. All materials radiate radiant heat in ranges from 0% to 100%.

FIBERGLASS INSULATION OR ANY INSULATION WITH AN “R” VALUE.

“R” VALUE = RESISTANCE TO HEAT

Fiberglass and other mass insulation only slows the transfer of heat, IT DOES NOT STOP IT. Once insulation is saturated, heat will flow freely into the home during the summer and out of the home during the winter. Regardless of how much insulation you have or do not have in your attic, adding radiant barrier foil insulation will save on your heating and cooling expense and keep you more comfortable. In fact, adding more fiberglass insulation will make the home more stuffy and uncomfortable by trapping the heat in, taking longer to release through the attic in the evening hours.

COST OF RADIANT BARRIERS

Radiant Barriers are the single most cost effective solution towards cutting your energy bills. Cost is comparable to fiberglass, blown-in, spray foam and cellulose, but has a strong return on your investment. It’s the only product that will pay you back year after year long after its been paid for.
