Even 20 inches of brand-new cellulose will underperform if you skip a blow in insulation cover fix around ceiling penetrations. Without proper dams and covers, loose-fill insulation spills into living spaces and leaves bare cold spots.
3 Essential Parts of a Blow In Attic Insulation Cover Fix
- Attic Access Hatch Dam & Insulated Cover: Build a rigid collar taller than the R-60 insulation depth, adhere foam board to the hatch lid, and apply compression weatherstripping ↗ ENERGY STAR.
- Recessed Pot Light Fire-Rated Covers: Non-IC rated recessed lights require airtight, fire-rated boxes before performing a blow in attic insulation cover fix so heat cannot ignite nearby fibers ↗ ENERGY STAR.
- Soffit Vent Baffles: Rigid chutes prevent blown insulation from covering eave vents, preserving roof ventilation.
