When it comes to attic insulation, two materials dominate the conversation — fiberglass and cellulose. Both can make your home more comfortable and energy efficient, but they perform differently in terms of moisture, sound, sustainability, and longevity.
At Smart Space Atlanta, we install both systems and tailor each project to the home’s structure, budget, and performance goals. Here’s how they stack up head-to-head.
Our Take
There’s no one-size-fits-all answer. For homes where moisture control and longevity are priorities, fiberglass is often the better choice. For homeowners who value soundproofing and sustainability, cellulose can be an excellent option.
Our team at Smart Space Atlanta will evaluate your attic conditions, air-sealing needs, and energy goals to recommend the best system for your home.
