Abstract
Compound fenestration assembly mull joints, compound fenestration assemblies using those mull joints, and methods of making and using the same are described herein. The mull joints in compound fenestration assemblies as described herein use universal joining strips to form both sides of a mull joint, as well as other universal components such as, e.g., corner gussets, locator plates, end plugs, seal members, etc. that may be used as needed to form mull joints as required in a compound fenestration assembly.

A compound fenestration assembly comprising:
- a first frame member of a first fenestration unit attached to a second frame member of a second fenestration unit along a mull joint having a first end and a second end,
- wherein the mull joint defines a mull joint axis extending along a length of the mull joint between the first and second ends of the mull joint,
- wherein the first and second frame members comprise exterior sides facing in the same direction and interior sides facing in an opposite direction from the exterior sides, wherein an interior/exterior axis extends between the interior and exterior sides in a direction transverse to the mull joint axis,
- wherein the first frame member faces the second frame member across the mull joint, wherein a separation axis extends through the mull joint between the first and second frame members, the separation axis extending in a direction transverse to both the mull joint axis and the interior/exterior axis;
- a first joining strip attached to the first frame member of the first fenestration unit, the first joining strip comprising a first end proximate the first end of the mull joint and a second end proximate the second end of the mull joint, wherein the first joining strip comprises a channel extending along the length of the first frame member, wherein the channel is aligned with the mull joint axis and opens towards the exterior side of the first fenestration unit;
- a second joining strip attached to the second frame member of the second fenestration unit, the second joining strip comprising a first end proximate the first end of the mull joint and a second end proximate the second end of the mull joint, wherein the second joining strip comprises a channel extending along the length of the second frame member, wherein the channel on the second joining strip is aligned with the mull joint axis and opens towards the interior side of the second fenestration unit such that the channel on the first joining strip mechanically interlocks with the channel on the second joining strip, wherein the mechanically interlocking channels prevent movement of the first frame member away from the second frame member along the separation axis, prevent movement of the first frame member towards the exterior side of the second frame member along the interior/exterior axis, and prevent movement of the second frame member towards the interior side of the first frame member along the interior/exterior axis;
- an intermediate end plug cavity formed between the first joining strip and the second joining strip, wherein the intermediate end plug cavity comprises a first opening at the first ends of the first and second joining strips and a second opening at the second ends of the first and second joining strips;
- a first end plug comprising a base and a cavity leg extending away from the base, wherein the cavity leg is positioned in the first opening of the intermediate end plug cavity when the base is positioned between the first and second frame members at the first ends of the first and second joining strips such that movement of the first and second joining strips relative to each other along the interior/exterior axis is prevented, wherein the cavity leg prevents disengagement of the mechanically interlocking channels on the first and second joining strips at the first ends of first and second joining strips due to movement of the first and second joining strips along the interior/exterior axis;
- and
- a first end seal member is located between the first and second frame members at the first ends of the first and second joining strips, wherein the first end seal member is located in a first recess between the base of the first end plug and the exterior sides of the first and second frame members, wherein the first end seal member comprises a sealant port in fluid communication with a sealant reservoir positioned between the first and second frame members and the first ends of the first and second joining strips.

- and
- a first locator plate positioned between the first joining strip and the first frame member, the first locator plate comprising a frame surface facing the first frame member and a joining strip surface facing the first joining strip, wherein the frame surface and the first frame member comprise complementary mating features configured to position the first locator plate in one selected location and orientation relative to the first frame member, and wherein the joining strip surface and the first joining strip comprise complementary mating features configured to position the first locator plate in one selected location and orientation relative to the first joining strip such that the first locator plate is configured to position the first joining strip in one selected orientation relative to the first frame member and in one selected location on the first frame member along the interior/exterior axis.
