North Dallas Bank Dallas, TX BEFORE: Original lockstrip glazing gasket system was 20 years old. This was allowing excessive water penetration to the glazing cavities. Consequently, insulated glass units were letting in moisture and losing their hermetic seal. Original gold coated glass was no longer available and similar replacement products did not match original appearance. CDC explored alternatives with building owners and developed design details, specifications and solicited pre-qualified bidders to renovate the existing system by discarding all of the original glass and lockstrip gaskets. AFTER: The custom designed “adapters” were attached to the existing aluminum grid system to accept new glass and horizontal framing members. The new glass was installed with structural silicone along the vertical edges. Exterior exposed framing elements were eliminated from vertical members for flush glazing look. Exterior horizontal framing changed to painted aluminum. New insulated glass with copper coating and insulated spandrel glass was installed. Insulation and fire-safing, when found to be in need of repair, was replaced/ upgraded during construction. CDC acted as owner’s construction manager and full-time inspector during all phases of work. Photography © 1993 & 1994 Wes Thompson Back to Portfolio
