Abstract
A sill arrangement for a fenestration frame includes a sill with a first chamber, a second chamber, a third chamber, and a fourth chamber. The sill includes a first internal wall that separates the first chamber from the second chamber. The sill arrangement also includes a corner key with a first port defining a first passage between the first and second chambers and a second passage between the second and third chambers of the sill. Moreover, a second port is included on the sill-facing surface that defines a third passage between the third and fourth chambers for allowing fluid to flow from the third chamber to the fourth chamber. The corner key further includes a drain in communication with the fourth chamber.
Claims20
A sill arrangement for a fenestration frame configured for supporting a panel, the sill arrangement comprising:
- a sill that is elongate and that includes a first longitudinal end and a second longitudinal end, the sill including a first chamber, a second chamber, a third chamber, and a fourth chamber, the sill including a first internal wall that separates the first chamber from the second chamber;
- and
- a corner key having a sill-facing surface, the corner key coupled to the first longitudinal end of the sill along the sill-facing surface, the corner key comprising:
- a first port included on the sill-facing surface, the first port defining a first fluid passage between the first and second chambers of the sill, the first port defining a second fluid passage between the second and third chambers of the sill;
- a second port included on the sill-facing surface and offset from the first port, the second port defining a third fluid passage between the third and fourth chambers;
- and
- a drain in fluid communication with the fourth chamber and configured to direct fluid from the fourth chamber and out of the corner key.
A fenestration unit comprising:
- a first panel;
- a second panel;
- and
- a frame that supports the first panel and the second panel, the frame including a sill arrangement that comprises:
- a sill that is elongate and that includes a first longitudinal end and a second longitudinal end, the sill including a first chamber, a second chamber, a third chamber, and a fourth chamber, the sill including a first internal wall that separates the first chamber from the second chamber, the sill including a slider rail configured to support the first panel for sliding movement on the slider rail within the frame, the slider rail being aligned with the first internal wall;
- and
- a corner key having a sill-facing surface, the corner key coupled to the first longitudinal end of the sill along the sill-facing surface, the corner key comprising:
- a first port included on the sill-facing surface, the first port defining a first fluid passage between the first and second chambers of the sill, the first port defining a second fluid passage between the second and third chambers of the sill;
- a second port included on the sill-facing surface and offset from the first port, the second port defining a third fluid passage between the third and fourth chambers;
- and
- a drain in fluid communication with the fourth chamber and configured to direct fluid from the fourth chamber and out of the corner key.
A method of assembling a sill arrangement for a fenestration frame configured for supporting a panel, the method comprising:
- providing a sill that is elongate and that includes a first longitudinal end and a second longitudinal end, the sill including a first chamber, a second chamber, a third chamber, and a fourth chamber, the sill including a first internal wall that separates the first chamber from the second chamber;
- and
- attaching sill-facing surface of a corner key to the first longitudinal end of the sill, the corner key comprising:
- a first port included on the sill-facing surface, the first port defining a first fluid passage between the first and second chambers of the sill, the first port defining a second fluid passage between the second and third chambers of the sill;
- a second port included on the sill-facing surface and offset from the first port, the second port defining a third fluid passage between the third and fourth chambers;
- and
- a drain in communication with the fourth chamber and configured to direct fluid from the fourth chamber and out of the corner key.
