Glass Packages
We offer multiple glass packages optimized for the DMV climate. Each provides different levels of performance to match your priorities and budget.
Best for: Most residential replacement projects
Two panes of glass with a Low-E coating that reflects heat while allowing natural light through. The sealed air space between panes provides insulation.
Best for: Enhanced efficiency at moderate cost
Same as double pane Low-E but with argon gas filling the space between panes. Argon is denser than air, providing approximately 15% better insulation.
Best for: Maximum efficiency and noise reduction
Three panes with two insulating gas spaces. Provides the highest thermal performance and sound insulation available.
Best for: Noise reduction and security
Combines Low-E energy efficiency with laminated glass that provides superior sound reduction and security.
