Print Window and Door Flashing Tite Seal Foam TITE SEAL FOAM THRESHOLD BARRIER is composed of a closed cell foam and a rubberized asphalt adhesive. It is applied underneath the threshold of a door in place of caulk. When the weight of the door is applied to it, it creates a gasket, sealing out moisture and air penetration. As it has an even surface, TITE SEAL FOAM THRESHOLD BARRIER eliminates the uncertainty of an uneven bead of caulk creating a substandard seal. In the case of an uneven sub-floor, the uneven surface can be filled with a patch of TITE SEAL FOAM THRESHOLD BARRIER before a continuous piece is laid over it. TITE SEAL FOAM THRESHOLD BARRIER is available in 5.5" x 3.5' rolls.
