Attic bypasses are hidden air passageways that lead from the heated space of your home into your attic. Warm air continuously rises up these passageways and escapes into the attic during cold weather. These bypass leaks can cut the energy effectiveness of your attic insulation by 30% to 70% depending on the amount of air leaks. Properly sealing these leaks can make your home more energy efficient, saving you money on your heating costs. Download for a detailed guide on how to find and seal attic bypasses and make your home more energy efficient.
