Curtain wall frame gaskets

A curtain wall system, comprising:

• a vertical member;
• a horizontal member coupled to the vertical member at a curtain wall joint;
• a first vertical bridge gasket coupled to the vertical member and a second vertical bridge gasket laterally offset from the first vertical bridge gasket, each vertical bridge gasket including:
• a vertically-extending interior gasket;
• a vertically-extending thermal break gasket;
• and
• a vertical bridge member extending between the vertically-extending interior and thermal break gaskets;
• and
• a first horizontal bridge gasket coupled to the horizontal member and joined to the first vertical bridge gasket at a corner joint, and a second horizontal bridge gasket vertically-offset from the first horizontal bridge gasket, each horizontal bridge gasket including:
• a horizontally-extending interior gasket;
• a horizontally-extending thermal break gasket;
• and
• a horizontal bridge member extending between the horizontally-extending interior and thermal break gaskets;
• wherein the first vertical and horizontal bridge gaskets cover the curtain wall joint between the vertical and horizontal members, and
• wherein the first and second horizontal bridge gaskets extend between the first and second vertical bridge gaskets, and
• wherein each end of the first and second horizontal bridge gasket is joined to a corresponding end of the first and second vertical bridge gasket at a corresponding said corner joint to define a continuous, unitary four-sided frame.

A method of sealing an interior of a curtain wall system including first and second vertical members laterally offset from each other and first and second horizontal members vertically offset from each other and coupled to the first and second vertical members at corresponding curtain wall joints, the method comprising:

• coupling first and second vertical bridge gaskets to the first and second vertical members, each vertical bridge gasket including:
• a vertically-extending interior gasket;
• a vertically-extending thermal break gasket;
• and
• a vertical bridge member extending between the vertically-extending interior and thermal break gaskets;
• coupling first and second horizontal bridge gaskets to the first and second horizontal members, each horizontal bridge gasket being joined to the first and second vertical bridge gaskets at corresponding corner joints and including:
• a horizontally-extending interior gasket;
• a horizontally-extending thermal break gasket;
• and
• a horizontal bridge member extending between the horizontally-extending interior and thermal break gaskets;
• joining each end of the first and second horizontal bridge gaskets to a corresponding end of the first and second vertical bridge gaskets at corresponding corner joints and thereby defining a continuous, unitary four-sided frame;
• and
• covering the curtain wall joints between the vertical and horizontal members with the vertical and horizontal bridge gaskets.
