Abstract
An end seal member, which includes a contacting surface including a drainage cavity along the contacting surface. The end seal member also includes a seal material body including a central body protrusion projecting in a horizontal direction substantially orthogonal to the seal material body from an opposite face of the contacting surface. The end seal member also includes a first and second extending elements extending upward from the seal material body and a reinforcing metal plate within the seal material body. The contacting surface is substantially flat.

- a first lower curtain wall unit including a first end seal member located at a mating face of the first lower curtain wall unit;
- the first end seal member comprising:
- a first contacting surface including a first drainage cavity along the first contacting surface;
- a seal material body including a central body protrusion projecting in a horizontal direction substantially orthogonal to the seal material body from an opposite face of the first contacting surface;
- a first extending element extending upward from the seal material body;
- a second extending element extending upward from the seal material body;
- and
- a reinforcing metal plate within the seal material body;
- a second lower curtain wall unit including a second end seal member located at a mating face of the second lower curtain wall unit;
- the second end seal member comprising a second contacting surface including a second drainage cavity along the second contacting surface;
- and
- the first contacting surface adjoining the second contacting surface thereby aligning the first drainage cavity and the second drainage cavity to form a chamfered recess.
