Expert Fiberglass Insulation for Homes in Connecticut
Fiberglass delivers reliable, cost-effective comfort—great for homeowners who want proven performance and year-round energy savings without overcomplicating things.
Fiberglass Insulation is a Solid Choice
The benefits of using fiberglass insulation.
Cost
Fiberglass is one of the most affordable insulation options out there. Solid performance, easy on the wallet.
R Value
Fiberglass holds its R-value well when installed properly—meaning your home stays warm in winter and cool in summer without working overtime.
Moisture Resistant
Fiberglass itself doesn’t absorb moisture, but if it gets wet or is installed with an incorrect vapor barrier, it can trap moisture and cause problems. That’s why proper installation and air sealing are just as important as the material you choose.
Non-Combustible
Fiberglass doesn’t burn. No treatments, no additives—it’s naturally fire-resistant, which makes it a safe bet for your home.
Sound Dampening
It won’t turn your house into a recording studio, but fiberglass does a nice job knocking down sound between rooms and floors.
Versatile
Batts, rolls, blown-in—you’ve got options. Fiberglass works in attics, basements, walls, and tight spots without making life complicated.
Low Maintenance
Once it’s in, it’s in. Fiberglass stays put, resists settling, and doesn’t attract pests to party in your walls.

When to Choose Fiberglass Insulation?
Here are common scenarios when fiberglass is the right insulation choice for you.
You’ve Got a Big Attic and a Budget to Watch
Need to cover a lot of square footage without breaking the bank? Fiberglass batts or blown-in options give you solid R-value at one of the best price points per square foot. Perfect for attics, basements, and bonus rooms that need a fast, effective solution.
You're Renovating or Building New
If the walls are already open, fiberglass slips right in—quick, clean, and cost-efficient. It’s a go-to for builders and remodelers who want reliable performance without the mess.
You Want Fire Resistance Without Extra Chemicals
Fiberglass is naturally non-combustible. No need for added fire retardants—just solid peace of mind baked right in.
You’ve Got Moisture-Prone Areas
Basements, crawlspaces, garages—fiberglass holds up well in areas where humidity can be an issue. It doesn’t absorb water, which helps prevent mold and mildew from making themselves at home.
You’re Just Looking to Knock Down the Noise
Got thin walls or loud teenagers? Fiberglass adds a layer of soundproofing that can make your evenings a little quieter—without the need for specialized (and pricey) acoustic setups.

Frequently Asked Questions?
Is fiberglass insulation safe?
Yes, fiberglass insulation is safe when properly installed and handled with care. During installation, its glass fibers can irritate skin, eyes, and lungs. Wearing gloves, masks, and protective clothing reduces exposure. Once sealed behind walls, it poses minimal health risks.
How long does fiberglass insulation last?
Fiberglass insulation can last 80 to 100 years under ideal conditions. Its performance may decline after 15 to 20 years due to moisture, settling, or damage. Regular inspections help identify when replacement is needed to maintain energy efficiency.
Where is fiberglass insulation best used?
Fiberglass insulation is best used in walls, attics, basements, and ceilings. It fits easily between studs, joists, and beams, making it ideal for unfinished spaces. Its thermal resistance reduces heat transfer and improves energy efficiency in both homes and commercial buildings.
Does fiberglass help with soundproofing?
Yes, fiberglass insulation helps with soundproofing by absorbing sound and reducing noise transmission. It’s commonly used in walls, ceilings, and floors to dampen airborne noise and improve acoustics. While not a full sound barrier, it provides noticeable noise reduction.
Can fiberglass insulation get wet?
Yes, fiberglass insulation can get wet, but it loses effectiveness when saturated. Moisture reduces thermal performance and can lead to mold growth. If it dries fully and remains undamaged, it may still be usable. Prolonged exposure usually requires replacement.
Is fiberglass better than cellulose or spray foam?
Fiberglass is more affordable and easier to install than cellulose or spray foam but offers lower R-values and air sealing. Cellulose provides better thermal performance and is eco-friendly. Spray foam has the highest R-values and best air sealing. The best option depends on your goals and budget.
Can you install fiberglass insulation over old insulation?
Yes, you can install fiberglass insulation over old insulation if it is dry, mold-free, and not compressed. Avoid adding insulation with a vapor barrier, which can trap moisture. Inspect for structural damage or pest issues before installing new layers.
Does fiberglass insulation itch?
Yes, fiberglass insulation can itch because its tiny glass fibers irritate the skin. Contact during installation often causes discomfort. Wearing gloves, long sleeves, and protective gear helps prevent irritation when handling fiberglass.
Reviews from our customers over 48 years
Nealon did an outstanding job in terms of courteous services, as their team members, as well as Chris who was responsible for directing the job, were most professional!!! They cleaned up nicely, and my goods remained intact. Also and happily stated, it’s been one week since they’ve installed insulation in our home, and we notice a huge difference in the amount of energy we are using for heating…which equates to $avings!!! In short, we’d use them again, and glad we chose them for this endeavor!!!
Highly recommended. Their estimate was competitive, the work was done in a timely and clean manner, they explained what was done, and our house is warmer as we head into the winter. When we had a question, they came back out to talk with us and helped us answer our questions. I will use them again and recommend them to anyone.
They are an amazing company to do work with! Jen in the office is polite, pleasant, and very competent. The work was done well and very quickly. We had our attic and basement insulated. I would 100% recommend!
The Nealon team was professional and considerate of my property. I noticed a 200-kilo watt decrease in my electric bill along with an additional savings in oil consumption of 50 gallons. No more drafty cellars and so far, the mice have gone elsewhere.
Fast, efficient and great price! Didn’t even notice them insulating our attic and making a big difference already! Would highly recommend for anyone that wants to cut down on their energy bill!!
