What is Structural Glazing?
Structural glazing, often referred to as glass curtain wall systems is a specialized facade method that attaches large glass panels to a building’s floors and walls using high-strength silicone sealants that act as an adhesive. The silicone seals form a weather-tight structural connection, allowing the glass facade to directly carry wind, snow, thermal, and dead loads back to the building structure. This glazing method creates expansive seamless glass surfaces without the visual interruptions of traditional aluminum framing systems. It delivers maximum light transmittance for building interiors along with unobstructed outward views.
Key Benefits of Structural Glazing
Structural silicone glazing delivers significant benefits for modern buildings:
- Light Transmittance – With expansive glass facade areas unencumbered by traditional frames or mullions, structural glazing maximizes interior daylighting, even in spaces far from perimeter windows. This enhances occupant comfort, productivity, and energy efficiency by reducing reliance on electric lighting.
- Views – The seamless glass surfaces allow uninterrupted outward views that connect building occupants to the exterior environment. Quality views have been linked to improved worker performance.
- Aesthetics – The modern, sleek, exterior glass surfaces create a striking visual appeal both inside and out. Structural glazing reflects current architectural trends emphasizing transparency and light.
- Energy Efficiency – High-performance low-emissivity glass coupled with insulating silicone sealants enables structural glazing systems to minimize solar heat gain and building envelope air infiltration. This increases occupant comfort and saves substantial energy costs.
- Acoustic Attenuation – Advanced sound dampening techniques can be incorporated into structural glazing construction to allow required noise reduction levels while still permitting expansive glass areas.
- Weather Resistance – Structural silicone offers exceptional durability and weather sealing capacity keeping out wind, rain, snow loads, and temperature extremes for quality performance over decades.
- Earthquake and Hurricane Resistance – The durable adhesive sealants maintain the glass wall connection to the building structure enabling the envelope to resist high wind pressures and seismic tremors.
- Lower Maintenance – Without aluminum framing, there is less material exposed to weather requiring periodic maintenance, repair costs, and repainting over the building lifespan.
