Fiberglass Insulation in the Attic 3 - Most Common Mistakes
Without further ado, here are the 11 most common mistakes.
- Not providing for good air circulation between the roof and the insulation
- Neglecting to find out the most efficient R-value for your area and insulate accordingly
- Installing fiberglass batting with the paper side (vapor barrier) facing toward the outside
- Omitting a vapor barrier that prevents the accumulation of moisture between the batting and the underside of the roof
- Puncturing the vapor barrier unnecessarily, or neglecting to puncture the vapor barrier of the top batt when installing two layers.
- Distorting, compressing, or squeezing the fiberglass batt insulation out of shape
- Using paper-faced batting against a heat source like chimneys, heating ducts, etc.
- Neglecting to get into all of the small spaces and corners with the insulation
- Covering eave vents with insulation, thereby cutting off ventilation.
- Not ventilating properly
- Making unnecessary trips up and down the attic stairs during installation. Assemble all tools and equipment in your work area prior to beginning the job.
