A lightweight and durable window well is composed of a long fiber reinforced thermoplastic (LFRT). The lightweight and durable window well has at least some fibers that are omnidirectional relative to the other fibers in the thermoplastic. Additionally, at least some fibers of the LFRT have a length greater than 40 mm. The window well also has a body having a plurality of ribs interposed between a plurality of wall surface portions. Additionally, each rib is positioned between two different wall surface portions and is defined by a variable height and a variable depth. Furthermore, the wall surface portions have a variable thickness that varies from a minimal thickness of less than 3 mm to a maximum thickness of greater than 5 mm, with the wall surface being thicker near the ribs than at portions furthest from the ribs in the wall surface.
A window well composed of a plurality of long fibers forming a long fiber reinforced thermoplastic forming a body having a plurality of ribs, wherein at least one of said ribs has a variable vertical height wherein the variable vertical height is parallel to a major face of the body, wherein at least some long fibers within the long fiber reinforced thermoplastic are omnidirectional, relative to other long fibers in the thermoplastic, and have a length of greater than 50 mm, wherein the variable vertical height of the at least one rib having a variable vertical height includes a smaller height in a center of the body and a greater height at ends of the body when the window well is in an installed position.
A window well composed of a fiber reinforced thermoplastic, the window well comprising:
