The ST-52's glass is attached to its aluminum frame using structural silicone. Special clips are used to affix the glass-frame set to the supporting profiles.

The ST-52 facade system distinguishes itself by offering a high style curtain wall solution with the ability to integrate fixed or operable windows that can open inward or outward.

A series of EPDM gaskets installed around the perimeter of each glass module offer an all glass exterior styling, as well as a weathertight barrier against the elements. A special overlap cover is used to conceal the space between gaskets.

With an ample glazing capacity of up to 1-1/2”, and the interior visible section of only 2”, the ST-52 facade system provides great energy efficiency, as well as thermal and acoustic insulation with the help of newly designed PVC thermal breaks and EPDM gaskets. The ST-52 is intended to provide a sleek and modern “all glass” exterior look.
