Why Choose Fiberglass & Cellulose Insulation?

Fiberglass insulation is known for its excellent thermal resistance and fire safety, making it a popular choice for homeowners. Cellulose insulation, made from recycled materials, offers superior soundproofing and is an eco-friendly option that helps reduce your carbon footprint. Both types of insulation can significantly lower your energy bills and improve your home’s overall comfort by maintaining consistent temperatures year-round.

Fiberglass and Cellulose Insulation FAQs

Which insulation works better in Pacific Northwest homes: fiberglass or cellulose?
Both perform well when installed correctly. Fiberglass batts are common in walls and new construction in Bellevue and Redmond. Blown-in cellulose is usually the better choice for attic upgrades in existing homes across Arlington, Everett, and Mill Creek because it fills gaps more completely and performs better in high-moisture conditions.
Can insulation be added on top of existing attic insulation?
Yes, as long as the existing insulation is dry and undamaged. Adding blown-in insulation on top of existing material is a cost-effective way to increase R-value. For homes in Burlington, Mill Creek, and Arlington where moisture has degraded existing insulation, full removal and replacement is recommended first.
What is the difference between blown-in insulation and batt insulation?
Blown-in insulation uses equipment to distribute loose-fill material evenly, making it ideal for attics and irregular spaces found in older Arlington and Burlington homes. Batt insulation comes in pre-cut sections for walls and floors. Blown-in is preferred for attic upgrades because it fills gaps and achieves more uniform coverage.
How much can new attic insulation improve energy efficiency?
Washington state recommends R-49 to R-60 for attics in Western Washington climate zones. Homes that are under-insulated can lose 25 percent or more of their heat through the ceiling. Properly insulated attics in Everett, Redmond, and Bellevue help heating systems run less often and reduce monthly energy bills year-round.
How do I know if my home needs more insulation?
Signs include uneven temperatures between rooms, high heating or cooling bills, cold floors in winter, or visible thin spots in attic insulation. For homeowners in Arlington, Burlington, Bellevue, Everett, Mill Creek, and Redmond, an on-site inspection is the most reliable way to assess insulation levels and identify where heat loss is occurring.
