Handi-Seal® Window & Door Sealant is Fomo's patented closed cell, low pressure window and door foam.  Handi-Seal complies with AAMA document 812-04, and will not bow or distort windows or doors.  Because of its Dry Seal Technology, Handi-Seal is the only patented formula designed to prevent moisture and mold problems by repelling water, unlike open cell formulas that absorb and trap water.

Handi-Seal® Window and Door Sealant is applied with a straw applicator or a professional dispensing unit for increased control and metering.  This product provides superior air-sealing properties compared to traditional materials such as fiberglass, mineral wool and caulk.  Handi-Seal Window and Door Sealant is formulated with a distinct gray color for easy identification assuring the right product selection.
