Everything You Need to Know About Fiberglass Insulation
Fiberglass insulation is a reliable and cost-effective solution that helps your home retain heat during cooler months and reject heat during warmer months, supporting consistent indoor comfort and improved energy performance. At Attic Buddies Insulation, we professionally install and upgrade fiberglass insulation to proper depth and coverage, helping your heating and cooling system operate more efficiently while improving overall home comfort.
Fiberglass Insulation FAQ
(What Homeowners Really Want to Know Before Scheduling)
❓ How do I know if my attic actually needs more insulation?
Most homeowners don’t realize their insulation is low until energy bills rise or rooms feel uneven.
If your attic insulation measures less than about 16 inches, your home is likely under-insulated by today’s standards. A professional inspection can measure this quickly and show you exactly where improvements help.
❓ Will adding insulation really make a noticeable difference?
Yes — when insulation depth is low, your home struggles to retain heat in winter and reject heat in summer. Proper fiberglass insulation helps stabilize indoor temperatures so your heating and cooling system doesn’t have to work as hard.
❓ Is fiberglass insulation better than what I already have?
In many homes, fiberglass performs extremely well because it:
✔ Provides consistent long-term performance
✔ Does not settle quickly when installed properly
✔ Resists moisture damage better than many older materials
✔ Works well with modern attic airflow systems
Often the issue isn’t the material — it’s simply not enough depth.
❓ Will insulation alone fix my comfort problems?
Sometimes — but not always.
Homes work best when three attic factors work together:
• Proper insulation depth
• Healthy attic airflow
• Protection from radiant heat
That’s why Attic Buddies inspections check the entire attic system, not just insulation.

❓ How long does fiberglass insulation installation take?
Most attic insulation upgrades are completed in one day or less.
Larger homes or removal projects may take longer, but your technician will explain timing before work begins.
❓ Do I need to remove my existing insulation first?
Not always.
If existing insulation is:
✔ Clean
✔ Dry
✔ Not contaminated
✔ Structurally usable
New fiberglass can often be safely added on top.
Removal is only recommended when insulation is damaged, dirty, or preventing proper performance.
❓ Will this create a mess inside my house?
No. Professional installers protect the attic entry, control equipment placement, and clean the work area before leaving. Most homeowners are surprised how little disruption there is.
❓ Is fiberglass insulation safe for my family?
Yes. Modern fiberglass insulation is widely used and safe when properly installed. It does not support mold growth and does not attract pests.
❓ How much does attic insulation usually cost?
Costs vary based on attic size, current insulation level, and preparation needs.
That’s why Attic Buddies performs an inspection first — so homeowners receive clear, measured recommendations instead of guesswork pricing.
❓ Do I really need an attic inspection first?
Yes — because insulation depth, airflow, moisture, and attic layout all affect the right solution.
Without an inspection, any quote would just be an estimate.
With an inspection, you get:
✔ Actual measurements
✔ Photo documentation
✔ Clear recommendations
✔ No pressure to proceed
Not Sure What Your Attic Needs?
Most homeowners don’t know their insulation level — and that’s completely normal.
An attic inspection takes a short time and shows exactly:
• Current insulation depth
• Airflow condition
• Areas losing efficiency
• Recommended improvements
Insulation Install Process
Our insulation installation process begins with a careful evaluation of the attic to ensure proper depth, coverage, and airflow pathways are addressed. We prepare the space by protecting access points and verifying ventilation before installing insulation evenly to the recommended level, helping your home retain heat during cooler months and reject heat during warmer months. Throughout the process, our team focuses on clean workmanship, accurate depth measurement, and balanced distribution to support long-term comfort, efficiency, and overall attic performance.
