What Are Modern Insulated Glass Units (IGUs)?
How multi-pane construction boosts performance
Insulated glass units are multi-pane assemblies designed to improve energy performance, comfort, and durability. Two or three panes of glass are separated by a spacer that creates a sealed airspace, then perimeter-sealed to block moisture and gas loss. The spacer contains desiccant to control humidity inside the cavity and prevent fogging. Primary and secondary sealants work together to deliver an airtight, long-lasting bond.
IGUs can be specified with clear, low-iron, tempered, heat-strengthened, or laminated glass, and enhanced with low-e coatings that reflect heat while maintaining visible light. Cavities are commonly filled with argon or krypton gas, and warm-edge spacers reduce thermal bridging at the perimeter. Key performance metrics include U-factor, solar heat gain coefficient, visible transmittance, condensation resistance, and sound transmission class.
Comfort, energy savings, and long-term value
Upgrading to high-performance glass units lowers heating and cooling loads, reduces drafts, and evens out interior temperatures near windows. Low-e coatings and gas fills cut heat loss in winter and heat gain in summer, delivering measurable utility savings and improved comfort.
Modern IGUs also diminish exterior noise, protect furnishings from UV fading, and minimize interior condensation on cold days. Safety, security, and resilience can be boosted with tempered or laminated makeups that meet glazing codes without sacrificing clarity.
Custom-built IGUs, precise fit, and clean workmanship
DH Glass offers double- and triple-pane IGUs, multiple spacer systems, argon or krypton gas fills, and a wide range of coatings including solar-control and passive low-e. Options include laminated for security or acoustics, tempered for safety, tinted or patterned glass for privacy, and low-iron glass for maximum clarity. Units are manufactured to your exact sizes and can be specified to meet ASTM E2190 and EN 1279 durability standards.
Our process starts with a consultation to define goals for energy, acoustics, and aesthetics, followed by a precise site survey and verified measurements. We advise on glass thickness, cavity width, warm-edge spacer selection, and coating type based on orientation and shading. Fabrication is scheduled with clear lead times, and every unit is quality-checked for seal integrity, dimensional accuracy, and optical quality.
Installation is performed by trained glaziers using industry best practices: correct edge clearances, setting blocks, compatible sealants or glazing tapes, and proper weeps for water management. We protect finishes, remove debris, and leave the work area clean. After installation, you receive care guidelines, product documentation, and a workmanship warranty from DH Glass.
