Fiberglass Insulation in Chicago, IL

Fiberglass Insulation Company in Chicago, ILYou’ve probably seen fiberglass insulation before — it’s the pink or colorful stuff that resembles cotton candy, and it’s one of the oldest and most popular types of insulation.

Fiberglass insulation has been around for about 80 years, and it’s still used in most homes to increase energy efficiency and lower energy bills.

What Is Fiberglass Insulation?

Available as loose-fill or blow-in or as roll batts/blankets, fiberglass insulation is used not only in many homes but in a variety of locations within homes, including the attic, basement, exterior and interior walls, any crawl spaces, etc.

Types of Fiberglass Insulation

Blown-in (loose-fill) fiberglass insulation is installed with a special blowing device and is ideal for small crevices, gaps and leaks in the attic and other areas of your home.

Batt fiberglass insulation comes in pre-cut panels, fits snugly between wall and floor joists and is best for basements and crawl spaces.

Benefits of Fiberglass Insulation

Higher energy efficiency is one of the most obvious benefits of insulation installation, but it’s not the only one! In addition to reducing your energy bills, fiberglass insulation can help:

  • Make your home more comfortable year-round
  • Help improve the efficiency of your air conditioner
  • Reduce outside noises
  • Increase the market value of your home
  • Promote a healthier environment (decreased energy consumption reduces carbon dioxide and other greenhouse gas emissions)

Wherever you install insulation, you’ll see and feel the difference it makes.

Some of the frequently asked questions we receive about fiberglass insulation include:

Can I layer new fiberglass insulation over old?

First, you need to get a free, professional estimate for re-insulating or insulation retrofitting the area you’re considering. If your insulation shows signs of water damage, mold or pest activity (chewing, fecal matter or urine), it must be removed entirely.

With insulation, sometimes less is more if it’s properly installed. Home insulation requires a small amount of air circulation. Cramming insulation rolls or batts atop old materials can increase energy loss and costs, and before adding insulation, you may need air sealing services.

Is fiberglass insulation safe to touch?

No. Never touch or work near fiberglass insulation without wearing protection:

  • Dust/facemask
  • Gloves
  • Goggles
  • Long sleeves

Any time you handle fiberglass insulation, airborne filaments can cause respiratory problems. Fiberglass spray polyurethane foam (SPF) has caused work-related asthma (WRA) at insulation project sites. Fiberglass has tiny glass particles that can get into or irritate your eyes and skin.

Should I get fiberglass batts or blown-in insulation?

It’s like apples and oranges. Both are good products, but where and why you need them determines which is best.

Fiberglass batts and rolls are the longest-lasting insulation solution and offer top-notch thermal energy savings. Batts and rolls are flexible and can be cut to size.

For odd-shaped areas or challenging spaces with nooks and crannies, loose-fill, blown-in fiberglass may be the perfect solution. It’s almost entirely made of recycled materials for a smaller carbon footprint.

Cellulose insulation is a bit cheaper than fiberglass and may have better noise-reduction properties.

Which is better, fiberglass or spray foam insulation?

Both materials have excellent thermal properties. Spray foam insulation often has higher R-values. It costs more, but you’ll have lower monthly energy bills, and your property value may increase, which gives you an edge in a competitive real estate market.

Fiberglass is the most popular insulator for attics and other areas in homes and commercial buildings. It provides superior thermal properties at less cost.
