Fiberglass insulation is a common insulation material made from fine glass fibers.
Why It Matters
Insulation helps slow heat movement, but it works best when the home also has proper air sealing, ventilation, and moisture control.
Common Problems
Common issues include compressed insulation, gaps, uneven coverage, blocked soffit intake, moisture staining, and confusing insulation problems with roof problems.
Building Codes & Industry Standards
Insulation requirements depend on climate zone, assembly type, local code, and energy requirements. Attic insulation should not block required ventilation paths.
Exterior Echelon Notes
Exterior Echelon may look at visible attic insulation during roof and ventilation evaluations because insulation, airflow, and moisture conditions often overlap.
