BUILDING ENVELOPE

DOOR AND RAMP SEALS Requirements: • To qualify, building interior space must be heated with natural gas during winter. • Dock door seals extend out to fill the gap between the dock door and the trailer, including the “hinge gap” that occurs with outwardly swinging trailer doors. • Leveler ramp air seals reduce air infiltration from around the loading dock leveler ramp. Air seals may be attached to the exterior of the building or around the edge of the ramp and must maintain an effective seal both when ramp is in use (raised or lowered) or out of use. Brush-type or whisker-type perimeter/edge seals may be used in conjunction with air seals but do not qualify for rebate.
