Beautiful skylights and glass roofs or domes in elegant hotels and conference centers as well as other institutional facilities across the nation add to the ambiance of the visitor’s experience…until moisture begins penetrating aging seals.
Expansion and contraction from changing weather conditions throughout the day and night begin to take their toll on systems used as glazing seals, causing leaks along the framework of the glass. When it came to the Hyatt Regency hotels, a strategy was required that would provide not only long-term performance but an aesthetically appealing restoration of the glass framework to appropriately reinforce the upscale style associated with the brand.
The development of a specialized extruded silicone overlay system, comprised of the Spectrem Restoration Overlay and Spectrem 1 Silicone Sealant, proved to be the answer. The UV stability of the silicone keeps it from degrading under the intense and long-term exposure to weather and the elements. Produced in a thin, precured configuration, expansion and contraction forces on the substrate are minimized while the flat profile provides a clean, aesthetically pleasing appearance.
The movement capability of the silicone overlay system is significantly higher than wet sealants at 200% or more, making the sloped wall and glass roof multidirectional movement no longer a problem. With all penetrations and screw heads completely covered, the potential for leaks is drastically reduced. The silicone extrusion was also produced in a dark brown to match the metal. Being silicone, the overlay exhibits excellent resistance to color fading.
