Sticking with Correct Sealant Application

Learning how to properly seal building penetrations will help prevent the permeation of air, gas, noise, dust, fire, smoke, or liquid from one location through a barrier into another.  "Although representing less than 1 percent of the structure, sealants' correct application is critical to the water and airtightness of the building. Since metal substrates expand and contract with changes in temperature, sealants (they consist of polymers that allow flexibility) aid metal panel joints that experience dynamic movement."
