    The Science Behind The Radiant Barrier And How It Can Help

    Insulation and keeping the house comfortable is a necessity especially when the temperature reaches seasonal extremes. Sure and air conditioning units are available but they always cost too much when used for days on end. This is when people start getting innovative and use energy saving alternatives.

    Texas summer in the 80s was the hottest so far in recorded American history. The heat came up to 99 degrees for 31 straight days. Even the AC unit have nothing against the summer heat. This is why people start installing alternatives such as a radiant barrier. This may not take away the discomfort, but it sure does help. During summers like the 1980s even people from suburban Richardson need to cut down costs.

    Reflective insulation systems are usually installed in attics to reduce the heat gain. Its high reflectivity absorbs the hotness gained from the sun. The effect is in the reflective surface facing the air space. The barrier is to be installed in a way where dust accumulation is lesser on the surface that does the insulation since dust can reduce the reflectivity of the material.

    The reflective surface of these barriers must always face an open air space and where dust will not accumulate. This is the most effective way of installation since the heat and light from the sun is absorbed by the surface. When the dust gathers on that reflective insulation system, the amount of energy it can insulate is compromised.

    These reflective barriers work better in hot climates than in cold ones. Since summers in suburban Richardson are hot, they are a more efficient solution. Cooling costs are reduced at around five to ten percent. While this may help reduce energy costs, the house orientation and the lifestyle of people living in it can still play a part in how much is spent on electricity.

    The way the barrier is positioned and installed can determine how effective the insulation is. When the panel is touches another surface, it starts becoming a conductor instead of an insulator. Like mentioned earlier, there must be airspace facing the reflective surface.

    While there are homeowners that would rather install the insulator by themselves, it is still highly recommended to talk and hire a professional. If the homeowner does choose to install it himself, it is best to follow the manufacturer guidelines religiously. Extra precaution is also required by referring to the local fire code and building laws.

    Windows also use reflective insulators and not just roofing. A layer of metalized film is coated on the glass. This coating is thin enough to let the light through but can still transfer radiant heat. These are used in one or more glass windows. Air and moisture may damage these metalized films and as a solution, manufacturers use it on windows with multiple pane.

    Homeowners worry that installing these radiant insulators on the roofing can damage the shingles due to increased temperature. The temperature of shingles with these devices on them do not go beyond 5 degrees Fahrenheit. The barrier even has the ability to lower roof temperature when the sun finally sets due to prevention of heat loss through the barrier. A study states that there was no big roofing manufacturers that said having reflective heat insulators would affect the shingles warranty.
