    摘要: A vertical expansion joint for connecting substrates in new of existing structures provides a fabricated seal, comprising a strip of cured, low modulus silicone attached to an open-cell polyurethane backer foam or, alternately, a closed cell polyethylene foam. The silicone strip of the joint is narrower than the backer foam and compatible with construction grade sealants, neutral cure sealants and room-temperature vulcanized sealant. The seal is inserted into the joint to be filled. A wet silicone sealant into the recessed areas on either side of the cured silicone strip. The wet sealant dries and creates a bond between the strip and the substrates. The resulting bond allows extreme expansion and contraction of the curtainwalls or substrates, while maintaining a watertight seal.
