Fassadenglas

Fassadenglas is a broad term for glass and glass-based assemblies used on building facades to provide transparency, daylighting, weather protection, and architectural expression. It encompasses both individual glass panes and complete facade systems that integrate with structure, framing, and shading devices.

Common forms include insulated glazing units (IGUs) with two or more panes separated by a spacer and often filled with gas for improved thermal performance. Glass types range from tempered and laminated safety glass to glass with coatings such as low-emissivity (low-E) or solar-control finishes. Functional variants include electrochromic, thermochromic, and suspended particle device (SPD) glass that can adjust transmittance. Facade configurations include unitized curtain-wall systems and stick-built assemblies with mullions, transoms, or structural glazing, among other attachment methods.

Performance and safety aspects are central in Fassadenglas selection. Key metrics include U-value (thermal transmittance), g-value (solar heat gain), and visible light transmittance (VLT). Acoustic insulation, wind-load resistance, and impact safety are addressed through design and specification. Laminated glass enhances security and safety, while fire-rated glass provides specified fire resistance for certain applications.

Design considerations cover daylighting and glare control, aesthetic appearance, energy efficiency, maintenance, and durability. The choice of glazing must balance comfort, energy use, and structural constraints while complying with local building codes and standards governing glazing and facade systems.

Sustainability aspects include potential for recycling at end of life, long service life, and contributions to reduced building energy consumption. Modern Fassadenglas aims to combine technical performance with architectural quality and environmental responsibility.
