Duct Sealant

Duct Sealant from The Duct Shop is of the highest quality water based sealants available for sealing your duct system. Duct sealant is necessary for proper installation of your new or replacement ductwork system. Ductwork systems that are not properly sealed can cause up to 30% heat loss in your home or office. Ductwork that is improperly sealed can also allow dirt, dust, and other contaminants into your air ducts which can eventually lead to poor indoor air quality.

Duct sealant is a product used for sealing joints, seams, and duct wall penetrations on metal air ducts. It can also be used to seal connections on flexible duct or fiberglass duct board. Duct sealant helps to seal all types of air ducts, which can reduce the risk of conditioned air leakage. Duct sealant is typically applied from caulking tubes or gallon containers with disposable chip brushs, or rollers.

Duct sealant is easy to apply and can be used on all types of metal ductwork, including rectangular, and round ducts. Duct sealant can also be used on fiberglass duct board, and flexible air ducts.

Installation Tip — Generously apply Duct Sealer to all metal to metal seams to fill in and gaps that air might leak out of any ductwork project. Allow to dry until firm to the touch before applying fiberglass insulation.
