A roll-out sheet of construction material has a plurality of slats, each with a shelf with a generally upward facing surface and a ledge with a generally downwardly facing surface. The plurality of slats are adjacent one another so that the ledge of one slat overlies the shelf of an adjacent slat. A load-bearing flexible film is secured to the plurality of slats on one side, the opposite sides of the slats from the flexible film are free allowing the slats to articulate relative to one another. The slats may have a longitudinal opening at least partially through, which is optionally filled with thermal and/or sound insulation, and/or load-bearing filler. The openings can also include a rib or support extending across the opening and bracing one side wall of the slat against the other. A securing tab can extend outward from one or more slats, shaped as a hoop, or having a through opening. When deployed, the roll-out sheet may be flat or have some angle or curvature. |
