Storefronts and Curtain Walls

Storefront and curtain wall systems typically include aluminum framing systems and insulated glass units, often with aluminum-framed, glazed doors and sometimes with operable aluminum-framed windows. While similar in appearance, storefronts and curtain walls employ differing drainage mechanisms and structural support and attachment methods. Details related to their design, detailing, and installation vary among manufacturers, and many systems have a variety of installation methods. Common problems with these systems include water leakage, air infiltration, failed insulated glass units, and excessive condensation.

BC&E personnel have extensive experience in evaluating a wide-range of problems with installed storefront and curtain wall systems. BC&E’s capabilities include performing and observing water spray testing of these systems in existing installations and in new construction, which facilitates the development of details to correct leakage problems. The consulting services offered by BC&E during the design stages of a project are aimed at facilitating proper specification and detailing of storefront and curtain wall systems, including their perimeter conditions, to reduce the risk of potential future problems.
