Everlastic® Weathertite R / Slot Seal Standard(CMU Control Joints)

Everlastic® Weathertite R / Slot Seal Standard(CMU Control Joints) Williams Masonry Control Joint materials are made of quality elastomers, meeting ASTM material standards. These control joint gaskets provide more than one functional feature for a given application. These custom designed seals furnish an excellent seal and function as a second line of defense when sealants fail from in-service use. These sealants will shed water and will reduce sound and thermal transmission. Shear loads from wind are transferred to the concrete masonry units with our gaskets in control joints.
