Fiberglass Vs Cellulose Insulation
Spray foam insulation is critical for home energy efficiency and comfort. Fiberglass and cellulose are two of the most commonly used attic insulation types, each offering unique advantages and considerations. Fiberglass batts are affordable, easy to install, and resistant to moisture, while cellulose, made from recycled paper, is environmentally friendly and provides excellent coverage in irregular spaces.
Fiberglass insulation has long-term durability and works well in standardized attic layouts. Its fibers resist heat flow effectively but may leave gaps if not properly installed. On the other hand, blown-in cellulose fills nooks and crannies better, preventing air leakage and reducing drafts. Understanding Insulation R-value helps homeowners compare performance and make informed choices.
How to Decide Between Them
Consider installation method, climate, and budget. Fiberglass is often chosen for DIY projects due to ease of handling, while cellulose may require professional installation for even coverage. Cellulose also has better soundproofing qualities and can be treated for fire resistance.
The best choice depends on priorities like cost, sustainability, and energy efficiency. In many cases, combining materials can maximize performance. Homeowners who evaluate both options can choose insulation that provides optimal comfort, efficiency, and long-term value.
