Abstract: An insulation window to be mounted on internal, in situ, window frames of buildings comprises a sheet of 3/16 inch rigid transparent plastic. The plastic sheet has spaced "hook-and-loop" fastening elements adhered directly to the plastic sheet about the margin of an inner face thereof and complementary hook-and-loop fastening elements are attached to the window-casing frames of the building. A weather stripping is adhered directly to the plastic sheet about the margin of the inner face thereof.

Abstract: An exterior window unit for covering the outside of an opening in a building wall. The unit has a frame header comprising a vertical mounting plate, a first horizontal plate projecting outwardly from the mounting plate, a second horizontal plate projecting outwardly from the mounting plate and spaced upwardly of the first horizontal plate, and a slanted surface extending downwardly from said second to said first horizontal plate. The second horizontal plate has at its outer end a drip flange projecting downwardly therefrom.

Abstract: An exterior window unit is adapted to cover an opening in a building wall. An adapter sill member has a vertical and a horizontal section adapted to be secured, respectively, to an exterior vertical and a horizontal top surface of a fixed sill in the building wall, the adapter sill member having a first engaging means extending along its lower edge. A frame sill of the unit has a mounting means having a vertical and a horizontal portion adapted to be secured, respectively, to the vertical and horizontal sections of the adapter sill member, the frame sill having a second mounting means having a second engaging means which engages the first engaging means.

Abstract: A fire and impact resistant window assembly comprising a multi-part centrally open marginal frame having an intermediate or inner groove which faces inwardly and first and second outer grooves which also face inwardly. The intermediate or inner groove receives marginal portions of a pane of fire glass which is thus secured in the frame and extends across the central opening thereof. The outer grooves respectively receive marginal portions of first and second panes of deflectable impact resistant polycarbonate and thus secure the panes in opposite spaced relationship with the fire glass. One pane of polycarbonate is approximately one half (1/2) inch in thickness and is spaced from the fire glass a distance of 0.35 inches. The other pane of polycarbonate is approximately one fourth (1/4) inch in thickness and is spaced from the fire glass a distance somewhat in excess of 0.35 inches.

Abstract: A storm window consisting of a rectangular window pane supported in a metallic frame is mounted over a window in a building by means of U-shaped channels mounted on the building and surrounding three sides of the building window. The storm window is slipped into channels and maintained in place by a friction or spring fit. The fourth side is closed by means of a U-shaped channel which is snapped or bonded onto the storm window frame.

Abstract: Sealing a building with flexible plastic sheets continuously wrapped and sealed therearound from base to above anticipated flood height. All glassed openings are covered with plywood before wrapping building, and drains below anticipated flood height are closed with inflatable bladders. Main application is to slab houses and wharehouses.

Abstract: A door construction provided with a window for use with a conventional baking and broiling oven. The window is formed with two glass panes which are widely spaced apart and are mounted independently of each other so there is no direct heat conductive path between the two glass panes. A dust sealing flange is located just beneath the window opening to reduce the opportunity of air-borne soil to reach up between the two glass panes.

Abstract: An extruded frame member for a window integrally includes guide channels for slidably receiving a window, an outwardly projecting drip cap and an outwardly projecting arm having an enlarged rounded end extending along the exterior of the frame member spaced inwardly from the drip cap. A window so formed provides the entire structure required for installing complete window units of any desired dimensions and for attaching storm windows or screens to such a window unit. The extruded frame member further includes means for locking conventional sliding or double and single hung windows slidably fitted in the frame.

Abstract: An exterior window unit for covering an opening in a building wall includes a frame sill which is slidable coupled with an elongated attachment plate member to be secured to a top surface of the fixed sill of a normally present window assembly in the building wall. To effect such coupling, the frame sill has a mounting fin having engaging means with a groove formed longitudinally therethrough. The attachment plate member has an engaging member which is complementary in cross-section to and received in the groove in the engaging means. The attachment plate member is thus positionable longitudinally relative to the mounting fin so as to be able to be interposed snugly between the side jambs of the normally present window assembly.

Abstract: An exterior window unit is adapted to cover an opening in a building wall. A frame sill of the unit has a mounting fin secured to a fixed sill in the building wall and having a first flange. An adapter sill plate is placed on and secured to the top surface of the fixed sill. The adapter sill plate has at its outer marginal edge a second flange which interfits with the first flange.

Abstract: A casement covering comprising a metal frame rigidly secured to glazing, the glazing being substantially shatter resistant, and means securing the apparatus to a casement comprising fasteners that cannot be removed by an ordinary screwdriver.

Abstract: An additional pane is added to an existing glazing installation to provide an insulating, sealed airspace therebetween.

Abstract: The conversion unit is a simple frame structure applied inwardly of a window opening, such as in a residential basement equipped with metal casement windows. It comprises a pair of like triangular end members or panels bridged across inner upright edges thereof by a light-transmitting portion in which a pair of ornamentally decorated sliding panels are mounted, as in a pair of overlapped grooves in a frame part of the panel portion. The unit is applied with outer vertical edges thereof in abutted engagement with a wall carrying the casement window and with upper margins of the generally triangular open frame structure in upwardly flush engaging abutment with the room ceiling just above the casement window zone. the sliding panels are chosen of a decorative plastic, semi-rigid sheet, preferably somewhat flexible in nature, and also by preference provision is made for a removal of the unit from the casement area for full access to the castment window from its interior.
