The SpecSeal® Quick Clip Field Installation System is engineered to significantly accelerate the installation of curtain wall insulation used in perimeter fire containment systems. Its innovative U‑bracket design clips directly onto mullions without the need for screws, enabling fast, tool‑efficient installation on the jobsite. For complex conditions, the system incorporates versatile Z‑brackets that accommodate corners, irregular geometries, and non‑standard mullion profiles. Once the insulation is placed, self‑locking fasteners secure the panels firmly in position, ensuring reliable performance and code‑compliant fire containment. The Quick Clip System also allows the elimination of stiffener channels in most applications where insulation thickness exceeds 2 inches. When a stiffener channel is necessary, it can be locked into place without any additional mechanical attachments, maintaining installation speed. Designed for maximum field productivity, the SpecSeal Quick Clip Field Installation System delivers a flexible, time‑saving solution for contractors installing curtain wall insulation in both new construction and retrofit projects.
