Abstract
A weatherproof curtain wall unit (U) comprises a rectangular frame (F) enclosing a panel (P) therein and a resilient weatherstrip (A) provided at least along a pair of vertical sides and an upper side of the rectangular frame (F). The resilient weatherstrip (A) is offset between the vertical sides and the upper side to prevent a gap from arising between the resilient weatherstrips (A, A) of the adjacent curtain wall units (U1, U2, U3).
