Air leaks in your attic and basement can really drive up warming costs if left unattended. This informative article provides some do-it-yourself tips on how to seal and insulate hvac ducts.
Just about the most energy efficient ways to make your home feel more at ease is by sealing and insulating your duct system.
When it comes to comfort, leaky air affects us most through the winter. While drafty windows and doors contribute to the issue, most significant air leaks in homes come from attics and basements.
If reducing your winter heating bill is often a top priority, then leaving basement and attic leaks unaltered is really a major mistake. Heat generated by homes during the winter naturally rises for the attic. Leaky attics allow heat to exit the home, providing cold air a way to enter in the method.
Repairing basement and attic leaks are necessary to maintaining a cushty home. In houses with forced-air air conditioning systems, ducts distribute conditioned air throughout the house. In a typical house, however, a number of the air that moves from the duct system is lost as a consequence of leaks and poorly sealed connections. This ends in higher electric bills and difficulty keeping the home comfortable; regardless how high the thermostat is set.
Since some ducts are concealed in walls and between floors, repairing them can be challenging. However, exposed ducts in attics, basements, crawlspaces and garages might be repaired by sealing the leaks with duct sealant.
Furthermore, insulating ducts running through spaces that always become hot in summer or cold in winter such as attics, garages and crawlspaces can help to save significant energy.
When the areas looking for sealing and insulation are accessible, then getting a contractor to remedy the issue might be avoided by doing it yourself.
Step one toward fully-insulated ducts is sealing the many points inside duct run to protect against air loss and drops in temperature. This is accomplished with a mastic or sealant that's brushed on and left to dry for at least 24 hours. How quick the air moves over the ducts determines how well it is going to hold temperature.
Well-sealed joints enable the ducts to carry air at the set temperature. Mastic is utilized because it will never degrade or shrink out of the joint. Duct tape shouldn't be used for this purpose, because it degrades and decomposes, leaving the joint leaky and unprotected.
In the event the ducts have been sealed, an insulating jacket must be wrapped across the duct. Duct insulation is typically made of fiberglass. Insulators might use rigid insulation or faced fiberglass. The fiberglass surface faces in toward the duct even though the foil protects the outside of the wrap, preventing heat loss and protecting the fiberglass within it. The insulation is applied in sheets that are cut to adjust to and seamed.
In the event the ducts are properly sealed, you'll enjoy more the reassurance of your home while spending less on energy costs.
