Technical Reference

System Types
Three distinct approaches to curtain wall construction, each suited to different project requirements and building types.
Assembled on-site piece by piece. Mullions, transoms, and glass panels are installed individually on the building face. Best for low to mid-rise buildings and projects with complex geometry.
Factory-assembled panels are lifted into place by crane and interlocked on the building face. The dominant system for high-rise construction due to speed and quality control.
Structural glass panels connected by point fixings (spider clamps) with minimal visible framing. Creates a seamless, all-glass appearance for lobbies, atriums, and feature facades.
Energy Performance
How thermal breaks and Low-E coatings work together to reduce energy consumption in commercial curtain wall systems.
The building envelope is responsible for up to 40% of a commercial building's energy consumption. Modern curtain wall systems use thermal breaks in the aluminum framing and Low-E coated insulated glass units to dramatically reduce heat transfer. The thermal break -- a polyamide or polyurethane insert -- interrupts the conductive path through the metal frame, while Low-E coatings reflect infrared radiation while allowing visible light to pass through.
Lower U-value = better insulation. Values shown in BTU/(hr-ft2-F).
DC Energy Code Compliance
Washington DC's building energy code requires curtain wall U-values of 0.36 or better for new construction. Our standard specifications exceed this requirement.
Glass Selection
Selecting the right glass for each zone of the curtain wall -- vision, spandrel, and solar control -- is critical for performance and aesthetics.
Double or triple insulated glazing units with low-emissivity coatings that allow visible light through while reflecting infrared heat.
Opaque glass panels that conceal floor plates, mechanical systems, and structural elements behind the curtain wall.
Advanced solar control glazing with spectrally selective coatings that maximize daylight while minimizing solar heat gain.
Our Services
From individual panel replacements to full system installations, we deliver the expertise commercial buildings demand.
Individual curtain wall glass panel replacement matched to your existing system specifications.
Complete curtain wall system design and installation for new construction and major renovations.
Upgrade aging curtain wall panels to high-performance insulated glass units with advanced low-e coatings, argon or krypton gas fills,
IGU seal failure diagnosis and panel replacement for fogged or moisture-compromised curtain wall units. We identify failed panels, source replacements,
Perimeter sealant inspection, removal, and replacement to prevent water infiltration and air leakage.
Rapid response for broken or damaged curtain wall panels from storm damage, thermal stress, or impact.
Engineering Standards
Every curtain wall system we install meets or exceeds industry performance requirements for wind, water, air, and thermal resistance.
Up to 75 PSF
Engineered for DMV wind conditions per ASCE 7 requirements. Systems designed for specific building height and exposure category.
Drift Capacity 2.0"
Curtain wall anchors accommodate building sway and seismic drift without glass breakage or seal failure.
AAMA 501.1 Tested
Field-tested water penetration resistance per AAMA 501.1 dynamic water test at 6.24 PSF static pressure.
U-0.24 or Better
Thermally broken aluminum frames with insulated glazing achieve code-compliant or better thermal performance.
How It Works
Every curtain wall project follows a rigorous engineering and installation process to ensure safety and quality.
Our glazing engineers inspect the curtain wall system, identify the glass specification, evaluate the framing condition,
We develop detailed specifications matching or upgrading your existing glass, coordinate structural calculations if needed, and plan the installation sequence.
Glass panels are custom fabricated to your exact specifications. Insulated units, coatings,
Our certified crew executes the installation with proper rigging, suspended scaffolding, or swing staging. All safety protocols observed, final inspection completed.
