ABSTRACT:
A sealant strip includes at least three layers of foam coated on one side edge with a waterproof elastomer. The strip is arranged as two outer layers sandwiching an inner layer. The outer layers are substantially equally compressible, and the inner layer is compressible to a different degree than the outer layers. When the outer edge of said strip is coated with said elastomer and then said strip compressed, said coating will tend to fold along the interfaces between the layers of foam.
