Building Glass for Modern Facades: Types, Performance & Sourcing

Building glass is a category of engineered glass products designed for architectural use in exterior facades, curtain walls, windows, and interior partitions. Shenzhen Dayang Special Glass Co., Ltd., established in 2017 and operating under the brand DYGLASS, specializes in the research, development, sale, and service of building glass including tempered glass, laminated glass, insulated glass, curved glass, and smart glass. This article provides a technical overview of common building glass types, their performance attributes, and how DYGLASS addresses the requirements of contemporary facade projects.

Why Building Glass Selection Matters

Modern architecture demands glass that balances safety, thermal efficiency, acoustic insulation, and aesthetic appeal. Improper selection can lead to higher energy costs, safety risks, or design compromises. Understanding the distinct characteristics of each glass type helps procurement professionals and architects specify the right solution for their projects.

Key Building Glass Types and Their Characteristics

The following are core building glass categories supplied by DYGLASS, each with specific construction and performance attributes based on verified product data.

Tempered Glass (Model DY-GH01)

Tempered glass is a type of safety glass processed by heat treatment to increase strength. DYGLASS offers model DY-GH01 in both flat and curved forms, including tempered glass with holes and polished edges. Available thicknesses range from 3mm to 19mm, with a light transmittance of ≥91%. Typical applications include curtain wall construction, furniture, bathroom, and office partitions. This product uses float glass as its primary material.

Laminated Glass (Model DY-JJ01)

Laminated glass consists of two or more glass layers bonded with an interlayer (PVB, SGP, or EVA) for enhanced safety, sound insulation, and UV protection. DYGLASS model DY-JJ01 is a tempered laminated safety glass available in types including bulletproof, fire-resistant, and curved laminated glass. Thickness ranges from 6.38mm to 50mm, with interlayer thickness options such as 0.38mm, 0.76mm, 1.14mm, 1.52mm, and 2.28mm. Light transmittance reaches 85%–92% for clear glass, and sound insulation is rated between 35–45 dB. It is intended for building construction, architecture, automotive, and solar energy industries.

Insulated Glass (Model DY-ZK01)

Insulated glass units (IGUs) improve thermal performance by sealing an air or gas-filled space between two or more glass panes. DYGLASS model DY-ZK01 is a tempered insulated glass that can incorporate Low-E coatings, argon gas fill, and warm edge spacers. Standard thickness configurations include 6mm+12A+6mm and 8mm+16A+8mm, with custom options. Glass types available are Clear Float, Low-E, Tempered, and Low-iron. Light transmittance ranges from 70% to 89%, and sound insulation is 30–45 dB. Gas fill options include air, argon, krypton, and xenon. This product is designed for curtain wall, window system, and building construction scenarios.

Curved Glass Capabilities

DYGLASS processes multi-curved, double-curved, and various shaped tempered glass, including trapezoid, spherical, pyramidal, S-shape, and cylindrical profiles. Curved insulated glass is also available, enabling complex facade geometries without sacrificing thermal performance.

Smart Glass and Decorative Options

The company supplies smart switchable glass (also known as magic switchable glass) that changes transparency on demand, as well as digital printed glass, ceramic frit glass, stained glass, and painted glass for design flexibility.

Step-by-Step Guide to Selecting Building Glass for Facades

1. Define performance requirements: Determine needed levels of safety (tempered or laminated), thermal insulation (insulated glass with Low-E and gas fill), acoustic insulation (laminated or insulated), and transparency.
2. Assess geometric complexity: For curved or irregular shapes, confirm that the supplier’s tempering and laminating lines can handle the required radius and shape. DYGLASS operates dedicated curved tempering lines for concave, convex, and irregular profiles.
3. Specify glass and interlayer materials: Select glass type (clear, Low-E, low-iron) and interlayer (PVB, SGP) based on structural loading, UV control, and fire rating needs.
4. Verify coatings and gas fills: For energy efficiency, choose Low-E coating and gas fill (argon/krypton) where applicable.
5. Request documentation and samples: DYGLASS is an Alibaba Verified Supplier and has passed SGS testing. Inquiry for test reports and product samples before ordering.

Use Cases and Project References

DYGLASS's building glass products have been applied in several notable projects across China and internationally. The company supplied architectural glass for the Guangzhou Financial City, Huizhou North Railway Station, China Nano Research Institute, Nanchang East Railway Station, Bahrain International Circuit, and Doha Metro Station. These projects illustrate capabilities in both standard and complex glass configurations for commercial, transportation, and institutional buildings.
