Four Reasons to Shy Away from Fiberglass Insulation

Having been in the home improvement industry for four decades, we’ve witnessed the evolution of building materials.  At one point, fiberglass insulation was the gold standard.  However, as technology has evolved, there are options, such as cellulose and spray foam, that create a more energy efficient home than fiberglass.  While these options may cost more than fiberglass, they are well worth the investment.  Still not convinced?  Here are the top four drawbacks of fiberglass insulation.

Coverage Concerns: Rarely are home attics perfect squares.  This presents an issue when trying to install fiberglass insulation, which is precut into lengths between 16 and 24 inches.  Attics also contain electrical outlets that should not be covered up by insulation and failure to properly insulate these areas creates heat loss.  If your insulation contractor doesn’t take the time to custom cut the insulation for these obstructions, your home energy bills can take a serious hit.

Moisture Issues:  A drawback that fiberglass insulation has over spray foam is its vulnerability to moisture.  This means that if your roof leaks into your attic or frost causes condensation which then melts, the material loses its insulative properties.

Mold Potential: It’s only a matter of time before mold growth commences on wet fiberglass insulation.  This scenario has a lesser chance of occurring on cellulose insulation because it doesn’t permit the unimpeded circulation of air that carries mold spores and moisture.  Floating mold spores that position themselves on the fiberglass insulation quickly reproduce when exposed to water vapor or condensation.  This compromises a home’s indoor air quality.

Problems with Air Exchange: Many home furnace filters are comprised of fiberglass because of the material’s ability to allow air to freely flow through it.  The same can be said for fiberglass insulation.  Both cellulose and spray foam insulation have a higher density, making them better choices for preventing air leaks.  This is why if fiberglass insulation is used on a project, it’s imperative that the contractor thoroughly examine the attic for any areas that need air sealing before the fiberglass insulation is placed.

Everyone (the steel roofers, spray foam installers, and LeafGuard® installers) was very professional yet personable and friendly. They did a great job while overcoming some difficult problems presented by my old 1 1/2 story house.

"I highly recommend Lindus Construction. They provide knowledgeable assessment with options for our consideration. All personnel develop a positive working relationship that goes above and beyond the requirements. Their honesty, communication, expertise, and hard work is exceptional. We have had both LeafGuard® and attic insulation successfully completed by Lindus. We are looking forward to our next project."

"Animals (bats and squirrels) caused a lot of damage in our attic. All the insulation had to be removed and replaced as well as vents repaired. They told us when they would do it and how long it would take and it was done on time. They did not make a mess and all the workers were very courteous and listened to our concerns. We would do work with Lindus again. They want to do things right!"
