AAttic Insulation, Air Seal and Ductwork in Dallas, TX

Lack of insulation, air leakage and deteriorating ductwork are a few of the many issues that this Dallas home was suffering from. Advanced Home Comfort answered the call, and worked to fix this uncomfortable home!

Fresh insulation

After sealing the attic, Advanced Home Comfort blew in some fresh cellulose insulation which is a very non-toxic and safe type of insulation, it is non flammable, it is rodent and insect resistant and is soundproofing.

Low Insulation R-Value

This attic has a low R-Value (resistance to heat) and is not blocking the heat from escaping from the living area of the home. The insulation is not thick enough to stop cold air from entering the living area during the cooler months. Vent soffits are covered with insulation limiting proper ventilation. Insulation, soffit ventilation and decking are all directly related to the attic's R-Value

Decking

Decking is a necessary part of the attic because of the air handler but it does decrease energy efficiency. The decrease is due to the decking not allowing the R-Value to be high enough. Typically the decking only allows for 4 inches of insulation under it but it is recommended to have 12 to 16 inches to resist heat.

Air is leaking through can lights

This Dallas home has 87 Can lights. Can lights are a major source of air leakage in the home. The fixture along with the hole creates a large gap for conditioned air to escape from the home. During the summer season, can lights allow hot attic air to travel into the home. As the air travels in and out of the home it carries dust and other allergens. The fiberglass insulation traps some of these particles creating the dark marks.

Unsealed top plates

Top Plates are where two rooms connect to each others and are a source of significant air leakage in homes. When the drywall crew comes in, they do the ceiling first. When they push the drywall toward the plates, they leave a gap to prevent damage from thermal expansion and contraction. And that leads to more air leakage.This house was no exception.

Duct work is a part of the game

In this case, ducts were not sealed at the attachment point causing more air leakage.

Insulation removal and air sealing

Advanced Home Comfort started this project by removing the old insulation and cleaning out the attic, then we sealed all the open penetrations and top plates, putting an end to Air leakage.

Can lights covers and sealing

Along with top plates, our crew installed can light covers on all 87 can lights present at this house, and sealed around them, preventing air from escaping through those spots.

Brand new decking

In order to prevent the decrease of energy efficiency while allowing the proper R-value, Advanced Home Comfort decided to install 4 inch SilverGlo under the decking. This can also be an option for storage areas.
