Duct Liner Encapsulation

What is a Duct Liner?

In many commercial HVAC systems the duct-work is lined with fiberglass to reduce noise and to keep conditioned air from escaping on the way to its destination.

What is Duct Liner Encapsulation?

Encapsulation is the process of using a sealant to re-cover the fiberglass lining of the air ducts.  If the fiberglass is too heavily deteriorated it must be replaced.  If the damage isn’t that severe it is possible to re-seal it instead.

What is the harm of a deteriorated duct liner?

As time goes on the fiberglass liner deteriorates exposing the fibers beneath.  As air travels through the ducting the exposed fiberglass can come loose and travel through the ducting and into the environment inside the building.  Fiberglass in the air can cause respiratory problems for occupants of the building.

What are some benefits of duct liner encapsulation?

Encapsulating your duct lining is more cost-effective than replacing the ducting.  Unless the liner is deteriorated beyond repair it is easier and cheaper to simply re-seal it.  Resealed lining means a restoration of air quality.  If there is mold in your duct-work a thorough cleaning followed by encapsulation can prevent further mold problems.
