Abstract
A sideways rollup door with a horizontal side-rolling curtain includes a replaceable bottom seal that is zippered or otherwise removably connected to the curtain at an inclined joint. The inclination of the joint ensures that the joint wraps upon the curtain's take-up roller in an approximate helical pattern so as to prevent the joint from creating a concentrated bulge on the roller. In some cases, there is extra space underneath the roller to provide roll-up room for the bottom seal, which can be relatively thick. Such extra space could be further used to accommodate a seal joint and/or other curtain seams that are not necessarily inclined.
