A doorsill for forming the bottom of an entryway. The doorsill has a substrate to be disposed above a subfloor and a lifter provided on the substrate capable of extending from a bottom of the substrate. The lifter is adjustable to change the orientation or position of the bottom relative to the subfloor.

An adjustable sweep door assembly includes a panel. A groove, positioned in a bottom of the panel, extends from proximate to a first side to proximate to a second side of the panel. Each of a plurality of openings is positioned through the panel and extends to the groove. The assembly comprises a plate that is rigid. Each of a plurality of biasers is coupled to the panel proximate to an associated opening. Each biaser also is coupled to a top face of the plate. A seal is coupled to a bottom face of the plate and extends from a first end to a second end of the plate. The seal is configured to sealably engage a threshold of a door opening. Each biaser is accessible through the associated opening, such that the seal is adjustably positionable relative to the bottom of the panel.

A prefabricated window sill (10) suitable for external use comprises a closed cast outer shell (12) having at least an upper surface (16), a lower surface (18), a front surface (20), a rear surface (22) and first and second end surfaces (24, 26). The shell is made from a composite of a plastic polyester resin mixed with either crushed marble or crushed glass, with a catalyst which causes the resin to set; the shell being filled with an expanded plastics foam.
