Dallas Roofing: Article About Insulation Around Air Ducts
In addition to installing insulation along a roof's rafters to increase a home's energy efficiency, many homeowners ask their roofers to wrap their attic's air ducts with insulation as well. Doing so helps to maintain a consistent temperature within the attic space and reduces the amount of unwanted air exchange with the home's heating and cooling system. Less thermal loss through the ducts can also help the homeowner cut their monthly heating and air conditioning costs. Experienced Dallas roofing contractors can use several different types of insulation around the ducts to achieve an increase in energy efficiency.
Foil faced insulation is the most commonly used material for insulating attic air ducts. During this work, the workers will wear long sleeves, pants, goggles, breathing masks and gloves to protect their skin, mouths and lungs from any fibers that come loose during the cutting and placing of the insulation. Before wrapping the insulation around the ducts, the roofers will repair any holes or loose connections or refer that work to an HVAC specialist. Once the ducts are in good condition, they can be insulated.

To begin, the roofers will measure the circumference of the duct and cut pieces of the insulation so that the insulation overlaps at the ends by a few inches when it is wrapped around the duct. Metallic adhesive tape is used to secure the seams and stick the insulation to the duct. The roofers will continue installing the foil faced insulation until all of the ducts are covered.
After the ducts are insulated, the roofers can install insulation along the roof's rafters and along the attic's floor to create a more energy efficient space. Any type of insulation can be used to do this, although the installers and homeowner should first determine what R value is needed and what material to use in order to achieve that recommendation. The only parts of the attic that should not be covered with insulation include vent openings, electrical wires and control panels for mechanical venilators like attic and whole house fans.
The results of installing insulation on the ducts, walls, ceilings and floors within an attic are instantaneous and significant. Insulation starts working right away so that none of the warmed or cooled air leaks out of the ducts. This results in more comfortable living quarters inside the home. The home's air conditioning and heating costs could drop by as much as 20 percent. After just a few years, the insulation can pay for itself due to the lowered energy bills.
