High performance buildings are dependent upon high performance building envelope systems that include window and curtain wall systems. If components within the window or wall system are not approached as a system, the result may be leaks and drafts which may cause occupant discomfort, indoor air quality problems, deterioration of the structural framing and excessive demands on the operational systems within the building.

To be effective, structural glazing systems must be designed as complete and unified systems, including frame, glass and glazing components such as structural silicone, gaskets, tape, blocks and other ancillary elements. Compatibility of these components is a primary concern to avoid loss of silicone adhesion to the glass or metal surfaces or staining.

There are many considerations in the design of effective glazing restoration solutions for today’s aging buildings. Total window replacement is costly and disruptive for building occupants. Cap beads are not the only alternative for repairing window systems.

The Low Memorial Library is located on the campus of Columbia University in New York City and was added to the New York City Register of Historic Places. It was erected using the best technology and craftsmen of the time, but time and the elements had taken their toll on the cast iron arched double-glazed windows. What had been designed to provide thermal efficiencies, had allowed moisture to get between the glass units over the years and fogging.

No construction materials can ever completely protect people from a direct bomb blast, but glazing systems can go a long way towards protecting building occupants and those outside the building from injury due to flying glass. To help capture and absorb the devastating energy generated by explosions, brutal impact and severe, sustained windloads, these systems must rely on silicone sealants formulated for the ultimate in tensile and tear strength, long-term flexibility and superior adhesion to glass and window frame materials.
Only the very best pass this test, and PROGLAZE SSG passes with ease.
There are numerous issues at the window-wall interface that compromise the integrity of the building envelope. A logical solution to remedy these issues is the development of pre-engineered transition assemblies.
The potential benefits are numerous:
Spectrem 1 Silicone Sealant – Spectrem 1 Silicone Sealant has broken all records for cohesive strength by forming tiny knots throughout its molecular structure. Any cuts are contained so when punctured or torn, the tear will not propagate throughout the bead.
Spectrem 2 Silicone Sealant – Spectrem 2 Silicone Sealant is formulated to ensure compatibility with other technologies, providing assurance of a durable, weathertight seal with adjoining Tremco systems.
