Fiberglass rolls remain one of the most reliable, affordable ways to insulate large areas quickly.
Fiberglass roll insulation offers a cost-effective and reliable way to insulate your home. Made from fine glass fibers, it’s designed to resist heat flow and reduce energy costs, making it one of the most popular insulation types for attics, walls, and crawl spaces.
At Attic Star, we install high-quality fiberglass rolls with precision, ensuring tight fits and complete coverage. Whether you’re upgrading outdated insulation or starting fresh, our team delivers clean, efficient results that enhance comfort, lower utility bills, and meet your budget goals.
Affordable energy efficiency Fiberglass roll insulation is one of the most budget-friendly options for boosting your home’s energy performance and comfort year-round.
Easy to install and customize Rolls can be quickly cut and placed to fit any area, making them ideal for attics, basements, and open framing.
Moisture and fire resistance Fiberglass naturally resists moisture and fire, helping to protect your home and improve overall indoor air quality.
It can last over 30 years when properly installed and kept dry, maintaining strong thermal performance throughout its lifespan.
Yes, modern fiberglass products are safe when installed correctly. We take all precautions during installation to prevent irritation or exposure.
Insulation performance is measured by R-value — a rating of how well a material resists heat flow. Higher R-values mean better insulating power per inch, which is why the right material and installed thickness matter as much as just "adding insulation."
Over time, insulation settles, compresses, or gets contaminated by moisture, pests, or age, which quietly lowers its effective R-value even though it's still physically there. That's why a visual inspection alone often understates how much performance has actually been lost.
The Bay Area's mix of coastal fog, inland heat, and mild winters means insulation here does double duty — keeping summer heat out and retaining warmth during cooler nights — so getting the material and coverage right affects comfort year-round, not just in one season.

Common signs include noticeably higher energy bills, uneven temperatures between rooms, visible damage or moisture staining, or insulation that looks thin, compressed, or discolored. A free inspection can tell you exactly what's going on.
Batt, blown-in, cellulose, fiberglass roll, and rockwool each have different strengths — cost, R-value per inch, fire resistance, soundproofing, and ease of installation in tight spaces all vary. We'll recommend the right fit for your home and budget during your inspection.
Properly installed insulation reduces how hard your heating and cooling system has to work, which typically shows up as lower energy usage — though the exact savings depend on your home's current insulation levels and how leaky or well-sealed it is overall.
