Attic Insulation In Hot Humid Climates

Insulation for a hot climate.

Attic insulation in hot humid climates.

Mold and mechanical insulation thermal insulation materials used for mechanical insulation do not support mold growth. If you live in a warmer climate the best way to avoid problems like wasted energy mold and peeling paint is to install better attic insulation and ventilation. The most important factor to consider in a warmer climate is the addition of a radiant barrier to whichever type of insulation you select. Conductive radiant and convective and i written about the difference between them in an earlier post.

Building materials once they become wet are more likely to remain that way. Learn more and request a free attic inspection. Leaky ducts in vented attics and vented crawlspaces lead to negative air pressures. This is a much greater threat in a hot and humid climate because of the time factor.

Radiant barrier is a foil that is placed between the attic floor and the insulation. Negative air pressures in buildings in hot humid climates induce infiltration of hot humid air. Un insulated attic spaces in hot humid climates easily reach 140 and higher so if you have an air conditioning duct with minimal insulation running through the hot attic you can imagine how much of the cooling is lost before it even gets to your rooms. A poorly insulated roof or attic or wall is cooler in winters and hotter in summer.

In hot climates the primary purpose of attic or roof ventilation is to expel solar heated hot air from the attic to lessen the building cooling load. Insulation alone is not enough. In hot climates ventilation is just as important for the opposite reason. Thus a good thermal insulation is a must to protect your building and enhance your living comforts.

Offering a clear range of air bubble thermal insulation products an extraordinary air bubble sheet which is developed with supervision and quality. There are three types of heat transfer. A radiant barrier is a material used in conjunction with attic insulation to reflect radiant heat at the surface and increase the efficiency of attic insulation. The amount of cooling provided by a well ventilated roof exposed to the sun is very small.

The difference is that in a southern climate the heat is outside trying to work its way in. The company can also decontaminate attics when rodents are present repair air ducts install radiant barriers and much more. Conductive losses also occur directly through insulation or where insulation is missing or thin.
