Engineered laminated glass stair treads with anti-slip treatments, LED illumination, and cantilevered floating designs. Structural engineering and custom fabrication across Washington DC, Northern Virginia, and Maryland.
A glass staircase transforms a functional element into the defining architectural feature of your space. From a floating glass staircase in a McLean estate to LED-lit glass treads in a Tysons corporate lobby, we engineer, fabricate, and install glass stairs that are as structurally sound as they are visually stunning.

Glass Tread Systems
From standard laminated safety treads to cantilevered floating designs with integrated LED lighting, we engineer glass stair systems tailored to your structural requirements and design vision.
The standard for structural glass stairs. Multiple layers of tempered glass are bonded with SentryGlas Plus (SGP) interlayers to create treads that are.
Every glass tread requires an anti-slip surface to meet building codes and ensure safe daily use.
Glass stair treads with integrated LED lighting create a dramatic architectural statement. Edge-lit configurations use the glass itself as a light pipe.
Treads mounted to a concealed steel stringer embedded in a wall, creating the illusion of floating glass steps with no visible support structure.
Why Glass Stairs
Glass stair treads allow natural light to pass through multiple floors, eliminating the dark stairwell effect of traditional stairs.
Multi-ply laminated glass with SGP interlayers exceeds building code load requirements. Anti-slip treatments meet OSHA and ADA standards. If a layer breaks,
Edge-lit and under-tread LED systems turn your staircase into a functional light fixture. Dimmable, color-tunable,
A glass staircase is the defining feature of any space. It transforms a purely functional element into a sculptural centerpiece that commands attention and e...
Three to four layers of tempered glass bonded with structural interlayers create redundancy. Even in the unlikely event of a single-layer failure,
Every glass staircase is custom-engineered for its specific span, load, and support conditions. Stamped structural drawings, building code compliance,

Engineering
Every glass staircase is a structural engineering project. Here is how we ensure your glass stairs are safe, code-compliant, and built to last.
Every glass tread is engineered to support a minimum 300 lb concentrated live load per IBC requirements. We calculate dead loads, safety factors, and impact loading to determine glass thickness, ply count, and interlayer specification for each unique project.
We use SentryGlas Plus (SGP) interlayers exclusively for stair treads. SGP is 100 times stiffer and 5 times stronger than standard PVB interlayers. This creates a monolithic glass panel that resists deflection under foot traffic.
Glass tread surfaces are tested to a minimum static coefficient of friction of 0.6, meeting both OSHA workplace safety and ADA accessibility standards. We verify slip resistance after treatment using ASTM C1028 or BOT-3000E testing methods.
The junction between glass tread and support structure is the most critical engineering point. We design custom steel or aluminum brackets with neoprene isolation pads that transfer loads while preventing glass-to-metal contact.
All glass staircase installations meet IBC Chapter 24 (Glass), Chapter 10 (Means of Egress), and ASTM C1048 (tempered glass) requirements. We coordinate with building officials in Virginia, Maryland, and DC for plan review and inspection.
Glass stair treads meet ANSI Z97.1 and CPSC 16 CFR 1201 safety glazing standards. Our laminated construction exceeds these requirements -- if the glass breaks, it remains bonded to the interlayer with no falling shards.
Applications
Glass staircases are the signature architectural feature in high-end homes across McLean, Great Falls, Potomac, and Bethesda. They transform a utilitarian element into a sculptural centerpiece that fills multiple floors with natural light.
Corporate headquarters, law firms, and financial institutions in Tysons, Arlington, and Downtown DC use glass staircases in their lobbies to project innovation and transparency.
Cultural institutions across the National Mall and throughout the DMV incorporate glass stairs as functional art. The transparency complements gallery spaces by maintaining visual openness.
High-end retail stores in Georgetown, CityCenter DC, and Tysons Galleria use glass staircases as architectural features that draw customers between floors while maintaining visual connection.
Boutique hotels and upscale restaurants in DC use glass stairs and treads to create memorable spatial experiences. The interplay of light through glass treads adds drama to hospitality interiors.
Multi-level condos and penthouses in Rosslyn, Navy Yard, and The Wharf use glass stair treads to connect levels without the visual weight of traditional stairs, preserving open floor plans and views.
How We Work
We visit your site to assess the stair opening, structural conditions, and design goals. For new construction, we review architectural plans. For retrofits, we evaluate the existing structure and identify any reinforcement needs.
We engineer the support structure, calculate glass ply requirements based on span and load, and produce stamped structural drawings. We coordinate with your architect and general contractor for seamless integration.
Glass panels are precision-cut, tempered, laminated with SGP interlayers, and treated with anti-slip surfaces. Brackets and hardware are fabricated to exact specifications. Lead time is typically 4-6 weeks.
Steel or aluminum stringers and brackets are installed and precisely leveled. For cantilevered designs, the concealed stringer is embedded and secured to the structural wall during the construction phase.
Laminated glass treads are set onto isolation pads, secured to brackets, and aligned. LED lighting is connected and tested. A final load test and slip resistance verification completes the installation.
We coordinate the final building inspection, provide all warranty documentation and care instructions, and demonstrate LED controls and dimming systems. Your glass staircase is ready for daily use.
