Before starting your building project, a careful selection of a qualified curtain wall manufacturer should be done in preparation of the shop drawings to ensure the manufacturing of the curtain wall system goes as smoothly as possible. Since these components are usually long lead-time items, manufacturing and/or field measurement deficiencies could result in the significant project delays. Improper field measurements, or lack of measurements prior to the preparation of the shop drawings, can lead to improperly sized components or misaligned connection points, which can be critical to the project schedule and can have serious consequences during the erection of the assembly. Attempts to make up lost time from construction delays can result in damage to the curtain wall structures as crews rush to meet unrealistic production targets.
In general, such a misalignment is often due to errors in laying out the structural framing system. A lack of coordination of building structure tolerances and curtain wall tolerances, or improper layout of imbeds to receive curtain wall anchors may also cause misalignment. In the case of coordinating construction tolerances, if the construction tolerance for the structural frame is +/- 1 inch over the height of the building and the tolerance for the curtain wall is +/- 1/4 inch over that same height, the curtain wall will need to be adjusted to conform to the tolerance of the structural framing. In order to be effective, the curtain wall manufacturer should be required to develop quality control procedures and checklists to help standardize and streamline the quality control (QC) process from fabrication to installation. Establishing measurements, field coordination and regular periodic checks during the curtain wall construction should ensure the correct manufacturing and installation of each prefabricated assembly and its components. Prior to production, these procedures should include checklists of quality control and inspection points to be reviewed for every assembly fabricated and installed. In the field, the QC checklist should include similar points for review and should note each panel’s final resting placement, or its unique address, on the building.
In addition, choosing the right curtain wall supplier to install, repair and maintain your building envelope makes all the difference. Especially before a building project will be completed, designing curtain wall frames and panels is a complex task as it involves load transference, thermal insulation, water resistance, and also needs to ensure panel adherence to frame, prevent dirt accumulation and allow for windows to be opened. In addition, your curtain wall system must comply with local building codes, including providing safe access for regular inspection, maintenance and repair. Furthermore, to enhance the architectural aesthetics, structural integrity and protection of your building facade, a good curtain wall manufacturer is also very important.
