Radiant Barriers and Blown-in Fiberglass: Double the Benefit

Radiant barriers and blown-in fiberglass create a well-insulated home that keeps most of the heat out during the hottest days of summer and the warmth from escaping in the chilliest of winters. This, in turn, not only saves precious energy, but also boosts the homeowner's savings on utility bills. It is a win-win situation in conserving money for both home heating and warming, particularly in the part of the house most vulnerable to temperature changes, the attic.

In order to understand how these two materials insulate one's home from the extremes of temperature, one has to know how radiant barriers and blown- in fiberglass work. The more popular form of residential insulation is the blown- in fiberglass. It works by creating a seamless blanket that provides a physical barrier to the movement of heat, one of the most touted advantage blown-in fiberglass has over other forms of insulation is that it does not trap moisture in between the surface and the insulator, creating long-lasting protection that spans more than 35 years. It is also fire-retardant and pest-resistant. It does not corrode.

Radiant barriers, on the other hand, stem from technology created by NASA which is then applied in a more domestic setting. These barriers are applied in the same way one would apply paint over a surface. It acts as a reflective layer that redirects energy, so it keeps heat out of the attic and decreases the temperature by 30 degrees. In colder months, it traps warmed air inside the room, which also reduces heating bills.

To use both types of insulation particularly in attics is not only effective but economical since using the two together will compound the beneficial effects each one possesses. Temperature protection in this susceptible area of the house will also afford other rooms below the attic with the same defense and benefits. Radiant barriers, although competent, do not last as long as blown- in fiberglass since their lifespan is only up to 15 years. However, combining both methods will provide the homeowner longer-lasting protection. When the radiant barrier has reached the end of its usefulness it can be reapplied. Also, insulation is better when both insulators are utilized in the home. Radiant barriers are usually applied to the ceiling of the attic, whereas blown-in fiberglass is applied on the lower part of the attic's. This makes the surface stronger and more capable of executing its functions and ensuring the residents with a satisfying and cost-effective means of controlling indoor temperature and saving on their energy consumptions bills.
