Moisture impermeable fire-barriers
An example of a pre-assembled, moisture, water, and gas impermeable fire-barrier system for use in expansion-joint spaces includes a fire-barrier having a layer of outermost protective cloth layer overlain by an insulation blanket overlain by stainless steel foil, overlain by a second insulation blanket, overlain by a limited layer of intumescent material, overlain by impermeable silicon coated cloth to completely or partially surround all of the other layers of the barrier. If desired, a first attachment apparatus for attaching a first long edge of the fire-barrier to a building unit and a second attachment apparatus for attaching the opposing second long edge to an opposing spaced building unit may be fixedly attached to the barrier. The barrier system may be fitted with a drain aperture and a drainage hose emanating from the aperture, the hose protected from the heat of a fire.
