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 rotobrush. 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.
Why is fiberglass of concern?
Fiberglass is composed of small glass fibers and glass is made from sand, which is a basic component of silica. Silica has been classified as a human lung carcinogen as well as linked as a leading cause to lung disease; in addition to greatly exasperating other respiratory issues such as asthma and emphysema. According to the American Lung Association, “over time, exposure to silica particles causes scarring in the lungs, which can harm your ability to breathe.”
How to prevent fiberglass from circulating in your home?
Encapsulation is a process used to seal the inside of fiberglass duct work. It locks down the fibers from becoming airborne thus preventing circulation of fiberglass throughout your home. The sealant used in this process is flexible to expand and contract with your duct work and includes a 10-year warranty.
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.
What are the overall benefits on 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
Advanced Furnace is certified through the manufacture of the product for encapsulation as an applicator. Training and certification provides our technicians with the proper knowledge for application and procedures to ensure the encapsulation is performed correctly.
