To shield a structure from summer heat gain or winter heat loss, fiberglass insulation depends strictly on its R-Value (resistance). Thin fiberglass layers do little to prevent
reflective heat or energy transfer, and are affected by humidity and moisture level changes. For fiberglass insulation, a mere 1 to 1.5 percent moisture level change could result in a performance decrease of up to 36 percent.
Reflective insulation or radiant foil barrier products such as Enerflex aren’t affected by humidity and moisture—unlike fiberglass insulation. Enerflex continues to
provide energy savings through its reflective insulation properites—whatever the moisture level. Also unlike fiberglass insulation, reflective radiant barrier foil may be used for radiant heat systems, or for application over or under concrete slab. In fact, reflective insulation may be your only choice for these uses.
Fiberglass, cellulose, rock wool and Styrofoam—the traditional insulation materials most people recognize—slow down or absorb convective and conductive heat transfers. They don’t block heat, however. Eventually, all of the heat radiated would transfer through these types of insulation. If you want to stop heat in its tracks, radiant barrier is your product of choice.
The challenge for home owners is keeping heat in during the winter and keeping it out during the summer. How does heat move from warm spaces to cold ones? By conduction, convection or radiation. Conduction is a direct flow of heat through a wall, ceiling or other solid object. Convection occurs when air is warmed; it expands, becomes less dense and rises. Radiation is what takes place when heat rays move from a warm object to a cooler one.
That heat you feel from your space heater? That warmth from the wood stove? That’s radiant heat. And it’s given off by all bodies and all objects—even your attic insulation, which loses heat to the cold attic space in cool months and gives it off to living spaces in warmer months. If you want to stop radiant heat loss, traditional insulation products are not the answer: Only a radiant barrier will reflect radiant heat.
