Insulated Glass Overview
Insulated glass, also called IGUs, uses two or more glass panes sealed around an air or gas-filled cavity. From double glazing to multi-pane units, this structure helps improve insulation, indoor comfort, and noise control.
Reach Building helps match the right IGU build-up to your project’s climate, application, and performance needs.

Low-E insulated glass is an IGU with a low-emissivity coating that helps control solar heat and thermal transfer.
Function Highlights
Used for: Curtain Walls · Windows · Facades · Glass Roofs
Laminated insulated glass is an IGU made with one or more laminated glass panes and a sealed air or gas space.
Function Highlights
Used for: Facades · Overhead Glazing · Hotels · Hurricane Zones
Vacuum insulating glass uses a sealed vacuum space between glass panes to reduce heat transfer in a slimmer unit.
Function Highlights
Used for: Slim Windows · Renovation · Residences · Energy-Saving Windows
4SG insulated glass uses a flexible warm-edge spacer and secondary seal to improve long-term IGU edge performance.
Function Highlights
Used for: Large IGUs · Structural Glazing · Facades
More Low-E coating layers usually provide better insulation, but also increase cost. View our Low-E Glass page for details.

Main Focus
Common safety glass with better sound reduction.
For hurricanes, railings, skylights, and fall protection.
For inserts, mesh, fabric, and visual effects.
Condensation Resistance
Reliable for standard IGU projects.
Warmer edge, less condensation.
Stronger seal. Longer performance.
Insulation Level
Standard one-cavity insulation for most projects.
Extra cavity for stronger thermal comfort.
Slim build-up for high insulation needs.
Tailored coating, spacer, gas, and thickness.
Supporting smoother specification review, procurement checks, and project documentation.
IGCC
For insulated glass quality verification and project review.
CE / EN 1279
Supporting European project requirements for insulating glass units.
ASTM E2190
Helping buyers complete documentation checks with confidence.
ISO 9001
Supporting quality management, process control, and factory consistency.
SGCC
Supporting safety glazing documentation and project specification review.
