Spandrel panel
Chronoglass’ high-quality spandrel glass solutions, available in tempered or insulated glass, are designed for curtain walls. Their opaque inserts offer superior thermal insulation and integrate perfectly with transparent sections. Customization is possible with a wide range of colors for optimum architectural harmony.
What is glass tympanum?
Spandrel glass is an innovative solution for curtain walls, offering both aesthetics and performance. Available in plain and tempered versions, it is ideally suited to the requirements of modern architectural projects. Chronoglass spandrel glass is designed to meet the most stringent criteria for durability, efficiency and regulatory compliance, ensuring long-lasting, high-performance installations.
Features and applications
Spandrel glass panels are opaque glass designed to cover building structures in curtain wall compositions, offering aesthetic and functional solutions for modern architecture. Their ability to conceal structural elements while harmonizing with transparent panels makes them a preferred choice for large-scale facades.
Technical characteristics of Tympanum glass
Tympanum glass panels can be manufactured as monolithic glass or integrated into a sealed unit, achieving a visual effect of continuity with transparent glass sections. This type of glass can be customized through coloring processes that add a unique touch to the design while enhancing opacity.
Spandrel glass is heat-strengthened to offer enhanced resistance to temperature variations and overloading. This tempering process also breaks the glass into small, non-sharp fragments in the event of breakage, ensuring optimum safety for overhead applications.
Visual harmonization
For aesthetic continuity between opaque panels and transparent sections, harmonization of visible light transmission (VLT) is essential. The use of glass with a high TLV percentage on spandrel panels, accompanied by an anti-reflective treatment, creates visual homogeneity. This adaptation is essential for architectural projects where visual appeal is as important as functionality.
Technical properties
The simple version of spandrel glass offers visible transmittance of 0.18 and external reflectivity of 0.35, ideal for applications requiring visual insulation while maintaining thermal efficiency adjusted to seasonal variations. In the tempered version, Tympan glass provides maximum thermal insulation with a visible transmittance of 0.00 and a high U-value, while meeting stringent safety standards such as ANSI Z97.1-2025. Both versions offer effective acoustic insulation with an STC of 30 dB and optimized solar control, maximizing interior comfort and reducing energy costs.
Applications and Uses
Spandrel glass panels are widely used in :
- Commercial and institutional building facades, where they provide a unique design while masking the structure.
- Curtain walls in multi-residential buildings, for a clean, modern look.
- Large-scale architectural projects aiming for a streamlined aesthetic, with glazing solutions that meet safety and durability requirements.
Spandrel glass is also prized for its design flexibility, offering architects and designers an unlimited palette of possibilities for customizing the appearance of their buildings.
Where to use it ?
The spandrel panel can be configured to suit specific project requirements. In its simple version, it is ideal for decorative or non-load-bearing applications. When greater mechanical strength is required, it can be tempered, offering additional protection against impact and heat. For enhanced safety, the laminated version retains splinters in the event of breakage, guaranteeing safe use. Finally, integrated into insulating glass units, it optimizes thermal and acoustic performance, meeting the most stringent requirements of architectural and industrial projects.
