A screen system for use with a sliding sash of a window to screen an opening as the sliding sash is opened includes a longitudinally extending tube and a spring extending through the interior channel of the tube. The system uses cartridge end caps for restraining the longitudinally extending tube in position within a cartridge housing. A mesh screen includes a leading edge, a trailing edge and opposed side edges. The mesh screen is of sufficient length and width to freely span and substantially cover the window opening when uncoiled and is wrapped around the longitudinally extending tube. The trailing edge of the mesh screen is secured to the longitudinally extending tube and the leading edge is attached to the rail of a window sash. The mesh screen can be unwound from the longitudinally extending tube as the sliding sash is opened, and wound back onto the tube as the sliding sash is closing.

A retractable material enclosure system that can be custom fit to provide a secondary barrier within an opening that is unobtrusive when not in use. The retractable material enclosure system may be used with different types of materials that are capable of being rolled about and retained on a cylinder or other drum type member when they are not extracted and in use. The retractable material enclosure system is particularly useful for providing a custom fit retractable screen door that fits within single or double door opening.

An apparatus for use with an overhead garage door includes an extensible screen that is provided in a screen assembly that is embedded within opening provided in a garage floor. A pair of horizontal and vertical recesses are provided on opposite sides of the opening to secure the screen assembly within the opening. The screen is wound on a spring-biased center roller disposed in a cylinder of the screen assembly. A top of the screen is secured to a strip. A pair of angled plates are disposed on opposite sides of the strip and are hingedly attached to the cylinder. When the garage door is lowered and extension of the screen is desired, a pair of pivot assemblies provided on the door bottom engage with the strip. As the door is raised, the strip and screen are extended from the screen assembly to cover an opening into the garage.

Corner tensioning and side edge retention systems for a motorized retractable screen system are disclosed. The corner tensioning and side edge retention systems are designed to maintain tension and/or prevent binding of a screen as it is moved between deployed and retracted positions.
