The 6 Myths Surrounding Attic Insulation

The 6 Myths Surrounding Attic Insulation

As a general contractor, we know that attic insulation has several persistent myths and misconceptions. These myths can sometimes dissuade owners from having their attics properly insulated. As a result, their home’s energy efficiency suffers and they have higher utility bills that could have been avoided.

The 6 Myths Surrounding Attic Insulation

In this post, 3JM Exteriors, Inc. discusses the six myths regarding attic insulation and the truth behind them.

  1. Attic Insulation Is a Fire Risk – Most types of insulation are actually non-flammable. You simply have to consult with your contractor on choosing the right one. Consider other options aside from spray foam, however, as this is one of the insulation types that can actually catch fire.

  1. The More Insulation, The Better – There’s only a certain amount of insulation you can install in your home. Once you reach that amount, surpassing it can actually block your roof’s ventilation which can result in moisture, which can lead to mold and rotting wood in your home. For professional installation of your insulation, hire window replacement and insulation experts 3JM Exteriors, Inc.

  1. Attic Insulation Is Unnecessary in Warm Climates – Regardless of your location, attic insulation is important since it prevents hot air from escaping your home during the winter months. It also prevents hot air from warming up your home in the summer. This can help a lot when it comes to energy efficiency since you won’t have to spend much on cooling and heating costs during those months.

  1. Attic Insulation Seals Air Leaks – Attic insulation by itself can’t actually seal air leaks. There has to be a separate vapor barrier installed. In addition, all holes for electrical lines, plumbing vents, light fixtures, and appliances have to be sealed with caulk to seal said air leaks.

  1. R-Value Is Constant – The R-value is the measure of a material’s heat resistance. The R-value of insulating materials actually varies and can increase or decrease. R-Values can be reduced if the material becomes wet. Insulation with high R-Values have greater performance and a longer life span but that doesn’t necessarily mean it will last forever.

  1. Attic Insulation Increases HVAC Efficiency – Proper attic insulation is merely one factor on how efficient your HVAC system is. Other factors include the HVAC’s size, whether the duct leaks, window and door drafts, and other sources of heat gain.
