SEAL YOUR AIR GAPS WITH ECO-INSULATION
Ceiling bypasses are hidden air passageways that lead from the heated space into the attic. Because warm air rises, it continuously moves along these passageways and escaping into the attic during winter. The reverse occurs in summer. So even though the roofspace above the ceiling could be at ambient temperatures, these bypasses make it possible for heat to travel into the house, hence wasting energy.
Eco-Insulation says that adding insulation alone without sealing air leaks is not going to help much. Also, water vapor carried with the escaping warm air in winter may condense and build up in the insulation, reducing R-values and causing structural damage. Indeed, When moisture problems appear in the roof after it has been insulated, ceiling bypasses are often the cause.
To avoid these types of water problems and to receive full benefit from your insulation, you need to plug up your attic bypasses. But before sealing they have to be found. Signs to look for are wet insulation, dirty insulation, dust build-up underneath the insulation and water staining under the insulation.
