Method and apparatus for ventilating an interior space, such as a large industrial structure with at least one bay opening. A ventilation system includes an array of M by N fans stacked into a two dimensional (2D) array. A rigid frame supports the array. A seal assembly provides a nominally fluid-tight seal between an outer perimeter of the array and the bay opening. A locking assembly mechanically couples the frame to the bay opening. In some cases, a bay door can be partially retracted and attached to a top of the frame. In other cases, the bay door may be fluidically permeable (e.g., a chain, a screen, etc.) and the array is secured behind a fully closed door. Cooling air is directed out the bay opening at a suitable time, such as overnight. A soft-start motor capability can be used to initiate operation of the array.

A lining is provided that covers doors or windows to provide protection against all inclement weather conditions. The lining prevents sunlight or any other type light from entering inside a room. The lining that includes horizontal slotted blinds that are operated manually using a flat cord. The horizontal slotted blinds work using tongue and groove concept.

This invention is directed toward a window for a garage door panel, where the window has an interior frame and an exterior frame. Both the interior and exterior frame have straight members that are secured to each other through the parts of the garage door that surround the opening with screws and screw receptacles. Connecting the frame members are corner braces, than come in a variety of designs, with some being invisible after installation and others forming a decorative corner to the window.
