Sacrificial glazing for a window assembly

A window assembly comprising, in combination:

• a frame defining a first and second channel;
• a windowpane sized to fit within the frame;
• a removable glazing panel having a peripheral edge;
• and
• at least one self-locking seal assembly securing the windowpane to the frame and securing the removable glazing panel to the windowpane, comprising;
• a channel glazing segment, secured to the frame in the first channel, and
• a wedge segment, positioned around the peripheral edge of the removable glazing panel and secured to the frame in the second channel, having a main body, a first interlocking arm extending from the main body, with a locking lip extending from the first arm, and a second interlocking arm extending from the main body and provided with a receiving groove to lockingly engage the locking lip, thereby securing the glazing panel to the windowpane.

An apparatus comprising, in combination:

• a windowpane and a frame;
• a transparent sheet of material sized to substantially conform to a peripheral shape of an interior side of the windowpane;
• and
• a self-locking seal assembly attached to the frame and seated against the windowpane, having a pair of locking arms unitary with one another and lockingly engaged with one another to secure the transparent sheet over the windowpane;
• wherein the self-locking seal assembly in a locked position captivates the windowpane and the transparent sheet of material, and in an unlocked position captivates the windowpane but does not captivate the transparent sheet of material.

A retrofitting kit for retrofitting a window assembly comprising, in combination:

• a transparent sheet of material;
• and
• at least one wedge seal segment comprising:
• a main body for releasably captivating a windowpane, having a substantially planar first surface adapted to be seated against the windowpane fixed in a frame,
• a first portion comprising a unitary protection extending from the main body, receivable into a channel in a frame, the unitary protection being remote from the first surface,
• interlocking arms unitary extending from the main body, movable between a locked position and an unlocked position, having a second surface which at least partially defining a recess formed free of the substantially planar first surface for receiving the transparent sheet of material when the interlocking arms are in the locking position,
• wherein the first and second surfaces are parallel with one another and with the recess when the interlocking arms are in the locked position, and are not parallel with one another when the interlocking arms are in the unlocked position, the first surface having a substantially fixed position relative to the first portion as the interlocking arms are moved between the locked and unlocked positions.

A window assembly comprising, in combination:

• a frame;
• a windowpane sized to fit within the frame;
• a removable sacrificial glazing panel substantially covering a surface of the windowpane;
• and
• a self-locking seal assembly which secures the windowpane in the frame and has interlocking unitary arms which releasably captivate the removable glazing panel;
• wherein the self-locking seal assembly captivates the windowpane and the sacrificial glazing when the unitary arms are in a locked position, and captivates the windowpane but does not captivate the sacrificial glazing when the unitary arms are in an unlocked position, and allowing to remove the sacrificial glazing panel independently of the windowpane.

A window assembly comprising, in combination:

• a frame defining first and second channels;
• a windowpane sized to fit within the frame;
• a removable glazing panel having a peripheral edge;
• and
• at least one self-locking seal assembly securing the windowpane to the frame and securing the removable glazing panel to the windowpane, comprising a channel glazing segment secured to the frame in the first channel, and receiving the windowpane, and a wedge segment, secured to the frame in a second channel and having unitary interlocking arms which releasably captivate the removable glazing panel.

A window assembly comprising, in combination;

• a frame;
• a windowpane sized to fit within the frame;
• a removable sacrificial glazing panel having a peripheral edge, substantially covering a surface of the windowpane;
• and
• a self-locking seal assembly having a main body which secures the windowpane in the frame and unitary releasable interlocking arms which urge a surface of the removable sacrificial glazing panel against a surface of the windowpane;
• wherein the self-locking seal assembly captivates the windowpane and the sacrificial glazing when the interlocking arms are in a locked position, and captivates the windowpane but does not captivate the sacrificial glazing when the interlocking arms are in an unlocked position.
