Abstract
A divided light window has a frame defining a plurality of light openings each of which receive an insulated glass unit. The frame has vertical and horizontal weep grooves cut therein to allow moisture to drain from the window, and a sealing system allows substantial shifting of the glass unit and does not interfere with the weep grooves. The insulated window unit is provided with a tape dam about its perimeter that is disposed opposite the weep grooves to prevent glazing material comprising the sealing system from entering and obstructing the weep grooves.
Claims15
A divided light weep and sealing system, comprising:
- a window frame unit including a top rail and a bottom rail connected at their end portions by a pair of vertically extending stiles to form an outer frame, and at least one set of horizontal mull bars and a vertical center bar affixed to an interior surface of said outer frame to define a plurality of light openings, an interior surface of said top rail being formed substantially along its entire length with a horizontal groove, respective interior surfaces of said pair of stiles and said vertical center bar being formed substantially along their entire lengths with respective vertical grooves, said vertical grooves opening at a bottom potion of said window frame unit;
- a plurality of insulated window units, one for each of said light openings, each window unit having at least an interior window pane and an exterior window pane separated at their perimeters by a continuous spacer;
- a strip of tape wrapped around a perimeter surface of each said spaced and being disposed substantially opposite to the grooves in said window frame unit;
- an interior bead of glazing material disposed around each said light opening at an interior window pane side of the grooves in said window frame unit;
- and
- an exterior bead of glazing material disposed around each said light opening at an exterior window pane side of the grooves in said window frame unit.
A light weep and sealing system, comprising:
- window frame means for defining at least one light opening, said window frame means including a continuous, groove in a top surface of said window frame means and extending vertically along side surfaces of each light opening so as to lead outside of said window frame means;
- insulated window means for providing a light window in each light opening, each window means comprising at least two window panes disposed face to face and divided at their perimeters by a continuous spacer and having a strip of tape adhered to a perimeter surface of said spacer;
- and
- resilient sealing means for sealing said insulated window means in each said light opening and for permitting expansion and contraction of said insulated window means within said window frame unit,
- said strip of tape being located substantially opposite the continuous groove in said window frame means.
