Glass Guide
Understand insulated glass (double- and triple-pane) and how glass choices affect comfort, energy efficiency, and clarity in your windows and doors.
Glass Basics
Double vs Triple Pane
Double pane is standard; triple pane offers maximum insulation for extreme climates
Spacer Systems
Warm-edge spacers reduce condensation compared to traditional aluminum
Gas Fills
Argon (standard) and krypton (premium) improve insulation between panes
Low-E Coatings
Multiple types and stacks available for different performance goals
Choosing for Your Goals
Comfort & Condensation
Better insulation means warmer interior glass surfaces and less condensation in winter
Energy Performance
Low-E coatings and gas fills reduce heat transfer, lowering heating and cooling costs
Sound Reduction
Laminated or acoustic glass packages significantly reduce noise transmission
Privacy & Tints
Obscure, patterned, or reflective glass options for bathrooms and street-facing windows
Common Glass Options
Laminated Glass
Two layers bonded with interlayer for safety and noise reduction. Ideal for ground-floor windows and high-traffic areas.
Tempered Glass
Heat-treated for strength; required by code for certain locations (near doors, low windows, bathrooms).
Patterned/Obscure Glass
Provides privacy while allowing light transmission. Perfect for bathrooms and street-facing windows.
Important Notes
Always verify model-specific performance with current manufacturer documentation. Confirm labels and certification where applicable (see ENERGY STAR page). Building codes may require specific glass types in certain locations.
