Protech's FansNSeal venting system delivers a quick and easy installation with an instant, firm, and positive seal. FasNSeal combines the FasNSeal fastening method with an innovative, built-in sealing system. There is no need to clean vent surfaces before applying sealants and no need for curing time. The heating unit can be started as soon as the installation is complete.


  • A welded butt seam is smooth inside and out, is vapor and water tight, and avoids application of sealants.
  • A built-in sealing system assures vapor and water tightness and avoids condensate "puddling" in the joints.
  • A built in fastening system makes installation a breeze.
