BS50-Series

BS50

Summary and Description:

The BS50-Series foam seal is composed of a high density, open micro-cell polyurethane foam impregnated with a hydrophobic, flame retardant, modified acrylic. The BS50 performs as a redundant secondary seal independent of the surface caulking.

The BS50 provides a watertight, dustproof, airtight, UV stable, chemically resistant soundproof, and insulated urethane secondary seal. The material works under its own constant internal pressure to provide a permanent, watertight seal eliminating costly water damage, as well as allowing for a greater degree of joint movement.

Once the BS50 is installed in the joint, the material expands (depending on temperature) adapting to the width of the joint and the irregularities of the substrate, provided such profile changes are not sudden or extreme. The material is permanently resilient. It will expand and contract with the movement of the joint under any weather condition.

Features and Benefits:

♦ Can accommodate rapid rates of joint movement
♦ Excellent compression recovery
♦ Permanently elastic and weather-tight
♦ Resists stretching and twisting during installation due to the Polyester scrim in the PSA (Pressure Sensitive Adhesive)
♦ Available in varying depths per size (contact manufacturer for more information)
♦ Allows for up to 100% (+/- 50%) movement
♦ Consistent depth of product
♦ Not based on asphaltic or bitumastic impregnation
♦ Paintable with water-based paints
♦ Available in multiple colors - contact EMS for color chart
♦ Sizes available in 1/4” increments
