Fortifiber's FortiSeal™ 8-1/2" x 11" Blank Through-Wall Boot is the answer to sealing pipe penetrations in a quick, easy and cost effective manner. Instead of using expensive bitumen or butyl products to cover the opening the FortiSeal™ easily creates a tight seal around various diameter of pipes. Blank boots allow you to cut your own holes to match the pipe. One 8-1/2" x 11" sheet can be cut in half to use on two penetrations.

The FortiSeal® Through-Wall Boot is 10 mils thick and extremely durable. The vapor permeance is .02 perms. The tensile strength and puncture resistance outperforms other flashing systems. An added feature is the flashing adds additional protection from insects and other pests getting into your structure through these openings.
