screenframe

A screenframe is a structural component designed to hold a screen in place, typically a window screen or a projection screen. For window screens, the frame is usually made of aluminum, vinyl, or wood and surrounds a mesh material, often fiberglass or aluminum wire, which prevents insects from entering while allowing airflow. These frames are often installed within or around the edges of a window opening.

In the context of projection screens, a screenframe refers to the support structure that holds the projection fabric taut and flat. These frames are commonly constructed from aluminum extrusions and are designed to be rigid to prevent wrinkles or sagging in the screen material. They can be permanent, fixed installations, or collapsible for portability. The shape and size of the frame are dictated by the dimensions of the projection surface. The frame's design is crucial for achieving optimal image quality by ensuring a uniformly flat projection area. Different types of screenframes exist, including fixed frames, motorized retractable frames, and manual retractable frames, each suited for different applications and user preferences.
