The Best Chicago Fiber Glass Company

Fiber Glass Pro's and Con's

Pros

A few of the advantages the insulation offers include the following:

  • Easy installation: The rolls or batts are manufactured to comply with standard joist width builders use for walls and floors. As a result, they are very easy to unroll inside the joists.
  • Moisture resistant: One important way insulation must perform is resisting moisture that may penetrate through the roof or humidity in the air. Fiberglass products do a great job of resisting moisture, so builders often choose to use it in higher-humidity regions. Because it can resist moisture, it is less prone to mold growth, which some other insulations are known for.
  • Noncombustibility: The material is noncombustible, or fire resistant, which is important for a material installed next to the home’s wood structure and for general household safety.
  • Renewability: Almost half of the material is recycled, and the other portion of the insulation is manufactured from sand, which is renewable.

Cons

In spite of its advantages, homeowners should also consider its downfalls:

  • Improper insulation reduces efficiency: Even though it’s easy to install, the insulation’s performance can decrease dramatically if it’s not installed properly. Gaps in the layers of insulation can drive down performance, as the gaps allow heat movement in between the insulation.
  • A lower efficiency overall: Comparatively speaking, fiberglass products don’t rate as high as some other insulations in terms of resistance (or R-value) per inch. In addition, when temperatures fall, the product loses performance value.
  • Energy hogging. To produce the insulation, manufacturers have to use a lot of energy, and the process releases a good deal of air pollution compared to other manufacturing processes for insulation types.

Why Hire a Fiber Glass Company?

Whether you choose fiberglass or cellulose, your insulation will only block the movement of heat. It won’t block the movement of air – and that matters.

In a typical home, air infiltration is endemic. Outdoor air is constantly entering your home through gaps and cracks in the building envelope. At the same time, conditioned air is leaking out. Due to the stack effect, most of this leakage occurs at the top and bottom of your home – your attic and crawlspace.

Sure, there’s insulation in your attic and crawlspace. But there’s probably nothing to prevent air from moving past plumbing, air duct, and electrical penetrations. Or attic staircase hatches. Or whole house fans.

In spite of all their benefits, neither fiberglass nor cellulose insulation provides an adequate air seal. While some research suggests that cellulose resists and/or blocks air movement more effectively than fiberglass, these materials are and should only be installed to reduce the passage of heat – not the passage of air. Only foam insulation and certain caulks can block air movement in a way that truly improves comfort and boosts energy efficiency.

Any time you’re thinking about adding insulation to improve your home’s thermal performance, consider air sealing as part of the same project. Have your insulation contractor seal all visible gaps and cracks inside the space you’re planning to insulate. You’ll improve the overall performance of the new insulation you’re buying.

You’ll also be more comfortable and save energy.

"Recently did my home. Tim and the Addison crew came out and did my attic properly as it should’ve been done the first time. Explained every single question (i had a lot) i had before and during the job. Tim made sure during the job they were doing the air sealing properly because that’s what makes the biggest difference in keeping the cool/heat in the house and so that it doesn’t get lost in translation somewhere in in the attic. Highly recommend and speak with Tim when doing work in your property!"

James is prompt, thorough, and personable -- responded to my website inquiry right away and made it easy to schedule an appointment (still haven't heard back from the competition -- that was three days ago). He provided a detailed and professional quote within minutes of being on site and saved me from spending $20k on an unnecessary new roof! I'm glad I contacted Green Attic.

Tim and his crew then came out to remove the old insulation, clear/kill all the mold in the attic, remedy issues that were causing the mold in the first place (insufficient ventilation and blocked soffits), and finally re-insulate our attic/basement. The work was intense, but Tim's transparency with the process and willingness to educate us on the problems that we were having were what sold us. We also appreciated that Tim was able to work in some added value into his services without charging us the difference.
