Abstract
An expansion joint cover having a vapor barrier channel depending from the bellows membrane. Resilient insulation substantially fills the channel, making it possible to attach an insulated vapor-impermeable bellows cover to the expansion joint members in a single operation. A separate layer of foam insulation may be bonded to the underside of the bellows independent of the insulation filling the channel.
