Product Details & Features

Insulating Glass Units, or IG units, are designed to support energy efficiency and sound control goals for projects. They can be fabricated to meet state energy and safety codes, acoustical and seismic requirements, impact, bullet, hurricane and blast resistance requirements. IG units can be designed to reduce heat loss and solar heat gain. A variety of make-ups, air space options, low emissivity coatings and decorative interlayers provide nearly limitless flexibility to meet a wide range of performance requirements.

IG Unit Applications:
• Vertical glazing
• Sloped glazing
• Overhead glazing
• Skylights
• Vision and spandrel (nonvision) areas
• Glass thicknesses: 1/8″ to 3/4″
• Airspace thicknesses: 3/16″ to 7/8″
• Double pane or triple pane
• Vacuum Insulating Glass (VIG) as thin as 1/4""
• Tested to ASTM E2190 Standard Specification for Insulating Glass Unit Performance and Evaluation.
• Certified by Insulating Glass Certification Council (IGCC) (US)
• Insulating Glass Manufacturers Alliance (IGMA) certification (Canada)

Applications

Insulating Glass (IG) units are used in essentially all exterior building applications, including vertical glazing, sloped glazing, overhead glazing and skylights, and also in both vision and spandrel (nonvision) areas.
Depending on the glass type used, IG units can be designed for: light and solar control, sound control, ultraviolet screening (to reduce fading), hurricane, earthquake and blast resistance, security, bullet resistance, and decorative applications.

Capabilities

IG units can have two, or three lites of glass, usually dependent on a project’s thermal performance requirements. The glass lites can be annealed, heat-strengthened, tempered or laminated and can be different thicknesses depending on applications.

The standard 1″ commercial Insulating Glass (IG) unit consists of two lites of 1/4″ glass and a nominal 1/2″ air space. Custom IG unit designs can be fabricated with glass thicknesses ranging from 1/8″ to 3/4″ and with airspace thicknesses ranging from 3/16″ to 7/8″ having standard spacer colors of clear, bronze and black anodized, and mill finish aluminum. Maximum sizes for IG units are determined by a number of considerations including thickness, weight, aspect ratio, application and load requirements.

Vacuum Insulating Glass, or VIG, leverages minimal airspace between two lites of glass to maximize thermal efficiency. The unit can be as thin as 1/4". Its slim profile makes it an ideal solution for replacement projects and historical applications to substitute a monolithic pane of glass. It can also be used in a traditional IG unit.

Glass options include clear, low iron, Low-E’s, standard or high performance (spectrally selective) tints, reflective, silk-screened, spandrel, laminated, decorative and wired glass. The glass lites of an IG unit can be annealed, heat-strengthened, tempered or laminated.

Oldcastle BuildingEnvelope® insulating glass units are independently tested and certified according to North American standards for quality and performance.
