HVAC Mastic Duct Sealant: Foster® 30-36™ from Bellis Australia

For energy-conscious specifiers, proprietors, and homeowners, sealing duct joints with a high-grade HVAC mastic duct sealant is one of the first lines of defence against energy wastage and pressure imbalances that affect every room. Aside from saving energy consumption and costs, HVAC mastic duct sealant prevents allergens, such as pollens, dirt, and dust from entering and circulating the HVAC system, causing poor indoor air quality and health conditions like asthma and allergy.

In the presence of leaking duct pipes, HVAC mastic duct sealant also prevents combustible gases, as well as deadly carbon monoxide, from passing through the leaks that could create a dangerous situation.
