Attics can be a huge energy drain if they are not insulated sufficiently. We’ll leave the
heavy lifting for next weekend, but for now look for uneven insulation, base sports, water damage, and anything else that looks out of place.
For even better results, look up your area’s recommended R-value and determine if you are using the optimal type of insulation. The R-value is a measure of thermal resistance used in the building and construction industry. The ideal R-value will be different based on your geography.
Also, be sure to use proper safety precautions! You’ll need gloves and a mask to go up there because fiberglass insulation can be very harmful.
