What is Encapsulation?
Encapsulating ductwork instead of replacing it can save both time and money while sustaining a higher level of ductwork efficiency. Coating the fiberglass liner or duct board not only increases the equipment’s longevity but also minimizes the cost of replacement. Encapsulating duct work improves indoor air quality by coating the system against dirt and dust while providing a ‘like new’ surface that is resistant to mold, mildew, and fungi. The product utilized for encapsulation contains EPA-registered components that make it resistant bacterial growth while providing a smooth, semi-gloss finish that facilitates improved airflow.

Benefits of Encapsulation?
- Prevents allergens, pollutants and other irritants from entering your ductwork
- Better indoor air quality especially for post-operative patients, and individuals with immune deficiencies, asthma, allergies and other respiratory issues
- Conserves energy
- Protects your home from fiberglass particulates circulating
- Prevents against insects and vermin entering your ductwork
- Overall a better quality of indoor air
Fiberglass & Ductwork –Roughly 50% of duct work is internally lined with fiberglass. Over a period, the fiberglass particulates from the internally lined duct work breaks down from air abrasion as well as fibers are loosened from improper air duct cleanings such as using a rotating brush. Under these conditions, fiberglass fibers circulate throughout your duct work and ultimately into your home. Additionally, duct work is built in sections and at each section break; you will find raw edges of fiberglass. These edges at the time of installation are supposed to be sealed; however, often, this step is missed leaving exposed fiberglass. This exposed fiberglass than enters the duct work and is circulated through your home. Click here to learn why fiberglass is of concern.
Regulatory reasons for encapsulation – In addition, the state of New Jersey follows the 2016 International Residential Code for Internal Energy Code Conservation and in the last 4 years new homes are required to be sealed with mastic to prevent air leaks and air infiltration to help create energy efficient homes. The sealing prevents loss of air and prevents irritants from entering in the duct work such as allergens including pollen, dust, etc., insects, vermin, fiberglass from attic and crawl spaces. Encapsulation is the solution to prevent loss of air, irritants and fiberglass in your duct work and home as well as meet building code standards.
Other reasons for encapsulation – Prior to the late 1980s, transite pipe was used for duct work in homes. Transite pipe is made of cement and asbestos fibers. Over time, the asbestos fibers break down and are circulated throughout your home. Once inhaled, asbestos fibers can become a risk to your health including: scarring of the lungs, shortness of breath, cancer causing agents and more. Additionally, sheet metal duct work will oxidize overtime from the constant moisture passing through from your air conditioning unit. The moisture causes sheet metal duct work to break down forming a white powder pollutant. This pollutant is then circulated throughout your home exasperating asthma and allergies. Encapsulation will prevent both asbestos and the pollutants caused from oxidation from circulating into your home.
