Curtain Wall Glass | High-Performance Architectural Glazing for Building Facades from KINGSTAR BUILDING GLASS
KINGSTAR BUILDING GLASS Curtain Wall Glass is a high-performance architectural glazing solution engineered for modern building facades. A curtain wall is a non-bearing exterior wall system suspended from the building structure, consisting of vertical mullions and horizontal rail members that support the glazing or window units. Our curtain wall glass products are available in tempered, laminated, insulated, and low-E coated configurations to meet the demanding requirements of commercial, institu
What is Curtain Wall Glass?
Curtain wall glass is the glazing material used in curtain wall systems—non-bearing exterior walls that are suspended from the building structure and do not carry floor or roof loads. A curtain wall is typically a nonbearing assembly of vertical mullions and horizontal rail members that support the glazing or window units. Curtain wall systems are distinct from window walls and storefronts in that they are designed to accommodate building movement, wind loads, and thermal expansion while providing a weather-tight building envelope.
Curtain wall glass serves two primary functions within the facade:
Vision Glass: Transparent glazing that provides views and natural light. Vision glass is typically insulated and may incorporate low-E coatings for thermal performance and solar control.
Spandrel Glass: Opaque glass panels located between areas of vision glass, aligned with floor edges. Spandrel glass conceals structural building components such as columns, slabs, insulation, and mechanical systems. Spandrel glass is rendered opaque using backpaint, ceramic frit, or specialty coatings.
Curtain Wall Glass Types
KINGSTAR BUILDING GLASS offers curtain wall glass in multiple configurations to meet different project requirements:
| Glass Type | Description | Key Characteristics | Best For |
|---|---|---|---|
| Tempered Glass | Thermally heat-treated for increased strength | 4-5x stronger than annealed glass; shatters into small fragments for safety | Vision areas requiring safety glazing, point-supported systems |
| Laminated Glass | Two or more glass plies bonded with PVB or SGP interlayer | Post-breakage integrity; fragments adhere to interlayer; enhanced security and sound insulation | Overhead glazing, security applications, acoustic performance |
| Insulated Glass Units (IGUs) | Two or more panes with sealed air/gas-filled cavity | Superior thermal and acoustic insulation | Energy-efficient facades, curtain walls |
| Low-E Coated Glass | Glass with microscopically thin low-emissivity coating | Reflects long-wave infrared heat; reduces heat transfer while allowing visible light | Energy-efficient buildings, solar control |
| Spandrel Glass | Opaque glass with backpaint or ceramic frit coating | Conceals structural elements; matches vision glass appearance from exterior | Non-vision areas between floors |
| Reflective Glass | Glass with metal oxide coating providing reflective appearance | Solar heat rejection; glare reduction; distinctive aesthetic | Facades requiring solar control and privacy |
Performance Parameters
| Parameter | Description | Typical Values |
|---|---|---|
| U-Value (Heat Transfer Coefficient) | Measures rate of heat transfer through the glass wall. Lower U-value means better insulation. | As low as 0.78-1.0 W/m²K for high-performance IGUs |
| SHGC (Solar Heat Gain Coefficient) | Measures how much solar radiation passes through. Lower SHGC provides better solar control. | 0.23-0.50 depending on coating |
| VLT (Visible Light Transmittance) | Percentage of visible light passing through the glass. | 40-85% depending on glass type and coating |
| Wind Load Resistance | Resistance to wind pressure loads as defined by building codes. | Per IBC requirements |
| Thermal Insulation (IGU) | Insulating performance of sealed units. | Complies with ASTM E2190 |

Frequently Asked Questions (FAQ)
Q1: What is the difference between vision glass and spandrel glass in curtain walls?
A: Vision glass is transparent glazing that provides views and natural light, allowing occupants to see outside. It is typically insulated and may incorporate low-E coatings for thermal performance. Spandrel glass is opaque glass located between areas of vision glass, aligned with floor edges, designed to conceal structural building components such as columns, slabs, insulation, and mechanical systems. Spandrel glass is rendered opaque using backpaint, ceramic frit, or specialty coatings.
Q2: What glass types are commonly used in curtain wall systems?
A: Curtain wall systems commonly use tempered glass (heat-treated for 4-5x strength of annealed glass), laminated glass (two or more plies bonded with PVB or SGP interlayer for safety and sound insulation), insulating glass units (IGUs) with argon or krypton gas fills for thermal performance, and low-E coated glass for solar control and energy efficiency. Point-supported glass curtain walls typically require tempered glass.
Q3: What standards do KINGSTAR BUILDING GLASS curtain wall glass products comply with?
A: KINGSTAR BUILDING GLASS curtain wall glass complies with EN 13830 (curtain walling performance), EN 12150 (thermally toughened safety glass), EN 1279 (insulating glass units), EN 14449 (laminated glass), IBC (International Building Code) structural and glazing requirements, ASTM E2190 (insulating glass unit performance), GB/T 26810-2011 (curtain wall glass), and GB 15763.2-2005 (safety glass).
Insulated glass is a glass assembly composed of two or more pieces of glass, evenly separated by effective support, sealed with a binder around the glass layer to form a dry gas space between the glass layers.Glass components can be made of clear glass, tinted glass, reflective glass, laminated glass, tempered glass, etc.according to customer's request.
Its excellent efficiency in solar heat insulation, greatly reduces cooling loads.
Dry air inside the enclosure renders the surface free from misting.
More excellent efficiency will be if fill in argon or other inert gases.rom misting.
