Abstract
An improved slat assembly and curtain for a rolling door assembly employing the improved slat are provided. The slat assembly has a primary slat with a lower bead having a downwardly facing cavity which is used to retain an elastomeric sealing strip which seals the space between adjacent interlocked slats in the curtain. The slat assembly may be provided with a backer slat and material filling a void between the primary slat and backer slat to improve the thermal insulation and/or acoustical insulation and absorption properties of the slat assembly and curtain.
