A glazing system that facilitates protecting windows from damage caused by high winds. The glazing system, for use with windows in doors, transoms, and in windows adjacent to doorways is an extruded polymeric frame that surrounds and supports and seals the window in place. The frame includes a stacked screw boss accessible from the exterior after removing a lineal cap. The screw boss receives screws use to hold a panel in place over the window during high winds to protect the window and which panel may be easily and quickly removed when the high winds pass. The interior side of the frame also has a screw path usable for attaching brackets for blinds to the back of the frame.

A window system according to an aspect of the invention includes: a window frame; an inner window installed at an indoor side of the window frame; an outer window fixed to the window frame and spaced apart from the inner window with a predetermined distance at an outdoor side to form a hollow layer between the outer window and the inner window; an air-flowing opening formed between the outer window and the window frame to form a flow path in which air in the hollow layer flows or circulates; and an opening and closing device provided at one side of the inner window to open and close the inner window from the window frame. The outer window may include a tinted glass or a glass having a high absorption rate and a bracket for fixing the tinted glass to the window frame.

A secondary window system installable within a primary window frame that includes a top horizontal member, a bottom horizontal member spaced from the top horizontal member, and first and second side members, the secondary window system including a top channel member attachable to and extending along at least a portion of the top horizontal member of the primary window frame, a secondary window frame comprising a header, a sill spaced from the header, first and second side jambs spaced from each other and extending from the header to the sill, and a secondary window opening defined by the secondary window frame, a top channel retainer engageable with the header of the secondary window frame, and at least one hanger engageable with the top channel member and the top channel retainer, wherein the secondary window frame is rotatably moveable relative to the primary window frame about the at least one hanger.

A novel and useful frame less supplemental window for fenestration suitable for use with existing windows. The supplemental window, in one embodiment, comprises plastic sheet material with bullnose edging around it. Corner braces add rigidity and strength to corners in several embodiments. An attachment mechanism secured either to the sheet material or the bullnose edge functions to fasten and/or seal the supplemental window to an existing window. The bullnose edging functions to substantially enclose (i.e. trap) a volume of air between the window pane and the plastic sheet material. The supplemental window is configured such that the layer of trapped air is of an optimum thickness within a preferred range of 0.15 to 0.75 inches to maximize thermal insulation properties of the supplemental window.

A supplemental window apparatus includes a foot and a first constraint element attached to the foot. The foot and the first constraint element are configured to be detachably coupled to a window pane of an existing window through a mating constraint element. A spacer is coupled to the foot and is configured to extend at least partially in a direction perpendicular to the window pane when installed on the existing window. A substantially non porous sheet is coupled to the spacer and has a sheet area substantially similar to a window pane area defined by the interior surfaces of the first window element holding the window pane. The spacer substantially defines a gap between the sheet and the window pane when installed on the existing window. The foot extends outward from the spacer toward the interior surfaces of the first window element.

A window insulation apparatus includes a cylindrical core having opposite top and bottom ends. A plastic sheet has opposite top and bottom ends and is pleated along parallel fold lines that extend parallel to the top end of the sheet to form a folded sheet. Adhesive is applied adjacent the top end of the sheet. The folded sheet is wound around the cylindrical core so that the top end of the folded sheet is near the top end of the cylindrical core. A housing receives the core and the sheet wound on the core. The housing includes an elongate opening from which the sheet can be unwound. A cutting assembly is mounted to the housing substantially adjacent the elongate opening and can be moved parallel to the opening for cutting the sheet that has been dispensed from the opening.
