The Best Attic Insulation Guide For Your Home

Mar 19, 2019Blog

Attic insulation serves as a good function at home for both hot and cold climates all year round.

A proper attic insulation installation is vital in maintaining a comfortable temperature at home for your family. Its main purpose is to slow the rate of heat transfer in both hot and cold weather.

During the cold season, insulating your attic helps to stop the flow of heat out of your house while during the hot season, it helps to slow the movement of heat into your house.

It can also help you save an average of 15% on your heating or cooling costs on energy bills during summer or winter.

It also prevents major damage in extreme weather conditions like an ice dam.

Here’s a quick guide on why you should have the best insulation for attic:

It Has A Good Return on Investment

Good attic insulation can let homeowners have a credit up to $500 or 10% of energy efficiency. There are a lot of types of insulation but according to Remodeler Magazine, there can be a 117% return on investment by getting fiberglass insulation as this type of insulation is ideally available and the most familiar.

Having an insulated attic keeps your home warmer in the winter and cooler in the summer. This helps reduce your heating and cooling costs.

It Avoids Stack Effect or Chimney Effect

An attic which is not properly insulated can cause what is called a “stack effect or chimney effect”. This is the movement of hot air which rises and escapes from the attic while drawing in cold air from the basement or leaks.

As heat escapes your roof, cold air sinks and goes through the basement and first-floor windows. During the summer, the reverse effect happens.

The hot air outside of your air-conditioned home can push cooler indoor air down from the ceiling and out of cracks in the basement which can cause moisture problems in your roof. This natural phenomenon creates air buoyancy which occurs when there is a difference from the indoor to outdoor air density resulting from temperature and moisture differences.

Thermal difference and structure height are directly proportional to buoyancy force, which simply means that buoyant force increases with a difference of temperature and the height of the structure. This leads to the stack effect or chimney effect.

Recommended Insulation R-values

R-value is a measure of your insulation’s ability to resist heat traveling through it. The higher the R-value your insulation has, the better performance it can have.

An appropriate insulation level is dependent on where you live. According to Energy Star, 13-14” floor deep is good insulation for most Southern climates while 16-18” floor deep is good for Northern climates.

R-value is determined by material type x depth. There are different R-values depending on your area. Refer to this R-value chart for more information.
