ABSTRACT:
A curtain wall structure has a framework comprising mullions that are each built up from a plurality of elongate members disposed end to end with expansion gaps between the members, and interconnecting means bridging said gaps transmitting bending loads between successive mullion members. Transoms of the framework at the expansion gaps comprise interengaging upper and lower elongate elements relatively displaceable to each other both vertically and horizontally in the plane of the framework. Resilient sealing members extend externally between the upper and lower transom elements at the expansion gaps. The framework is secured to a load-bearing structure by attachment members engaging both the mullion members and their interconnecting means at positions spaced from the expansion gaps.
