The Commercial Glass Landscape in the DMV
The DC metro area is one of the most active commercial real estate markets in the country. From retail storefronts along Wisconsin Avenue and King Street to Class A office buildings in Rosslyn and Tysons, commercial glass is everywhere -- and choosing the right glass for your business involves different considerations than residential projects.
Commercial glass must meet stricter building codes, energy standards, and accessibility requirements than residential glass. It must withstand higher traffic, more frequent cleaning, and greater security demands. It also represents your business to every person who walks past or enters your space. The right glass creates an inviting, professional, and secure environment. The wrong glass creates problems that are expensive to fix after the fact.
This guide walks you through the key decisions: what type of glass system you need, what codes and standards apply, what glass types are available, and how to plan a commercial glass project that stays on schedule and on budget.

Codes and Compliance for Commercial Glass
Commercial glass installations in the DMV are subject to more stringent requirements than residential projects. Understanding these requirements early in the planning process prevents costly redesigns and inspection failures.
Building Code Compliance
DC, Virginia, and Maryland each adopt the International Building Code (IBC) with local amendments for commercial construction. Commercial glazing codes specify safety glass requirements for doors, sidelights, and areas near walkways. They also regulate glass in hazardous locations, overhead glazing, and glass guard rails. Every commercial glass installation must pass inspection by the local building department. We ensure code compliance on every project.
Energy Code Requirements (ASHRAE 90.1)
Commercial buildings must meet ASHRAE 90.1 energy standards, which regulate the thermal performance of the building envelope including all glazing. The standard specifies maximum U-factor and SHGC values based on the window-to-wall ratio of the building. Buildings with more glass must use higher-performing glass to compensate. We specify insulated glass units with Low-E coatings and gas fills that meet or exceed ASHRAE requirements while providing clear, attractive storefronts.
ADA Accessibility
The Americans with Disabilities Act requires commercial entrances to meet specific accessibility standards. Door width must provide at least 32 inches of clear passage. Threshold height cannot exceed 1/2 inch. Hardware must be operable with one hand without tight grasping, pinching, or wrist-twisting. For many public accommodations, automatic door operators are effectively required to meet the spirit of ADA. Non-compliance risks federal fines, lawsuits, and loss of business from customers who cannot access your space.
Minimal Business Disruption
We understand that your business cannot afford extended closures. We schedule installations during off-hours, weekends, and early mornings. For phased projects, we work section by section to keep your business operational throughout the installation. Temporary barriers and protection are installed to keep your space clean and your customers safe during any work that must occur during business hours.
Commercial Glass Types Explained
Different commercial applications require different glass types. Understanding the options helps you specify the right product for your project.
Tempered Glass
Heat-treated to be 4 to 5 times stronger than standard glass. Required by code for doors, sidelights, and areas near walkways. Shatters into small, safe pieces on impact. The most common glass type for commercial storefronts and interior applications.
Laminated Glass
Two glass layers bonded with a PVB interlayer that holds the glass together when broken. Required for overhead glazing and recommended for security applications. Available with tempered layers for maximum strength and safety.
Insulated Glass Units (IGUs)
Two or more glass panes separated by a sealed air or gas space. Essential for energy code compliance in commercial storefronts and curtain walls. Available with Low-E coatings, gas fills, and warm-edge spacers for maximum thermal performance.
Spandrel and Ceramic-Frit Glass
Opaque or patterned glass used to conceal floor slabs, columns, and mechanical systems in curtain wall buildings. Spandrel glass maintains a uniform exterior appearance while hiding structural elements. Available in custom colors to match the vision glass.
Low-Iron (Ultra-Clear) Glass
Standard glass has a slight green tint due to iron content. Low-iron glass eliminates this tint, providing true color neutrality. Essential for retail displays, art galleries, and any application where glass clarity matters.
Switchable Privacy Glass
Electrically switchable glass that transitions from transparent to opaque at the touch of a button. Used in conference rooms, executive offices, and medical facilities where instant privacy is needed without physical blinds or curtains.
Frequently Asked Questions
Can you install commercial glass after business hours?
Yes. We schedule most commercial installations during off-hours, weekends, and early mornings to minimize disruption to your business operations. For retail storefronts, we coordinate with your schedule to ensure the business remains operational throughout the project. Emergency repairs are available 24/7.
What commercial glass meets ADA requirements?
ADA compliance for glass involves several factors: entrance doors must provide a minimum 32-inch clear width, threshold height cannot exceed 1/2 inch, hardware must be operable with one hand without tight grasping, and automatic door operators are required for many public accommodations. We ensure every commercial entrance meets current ADA guidelines.
How long does a commercial storefront installation take?
A standard single-storefront installation takes 1 to 2 days. Multi-unit storefronts or full curtain wall replacements may take 1 to 2 weeks depending on the scope. We provide detailed timelines in our project proposals and work to minimize disruption to your business during installation.
Do commercial buildings need special energy-rated glass?
Yes. Commercial buildings in the DMV must comply with ASHRAE 90.1 energy standards, which specify maximum U-factor and SHGC values for commercial glazing based on the window-to-wall ratio. We specify glass that meets or exceeds these requirements to ensure code compliance and reduce operating costs.
What type of glass is best for storefront security?
Laminated glass is the best choice for storefront security. Unlike tempered glass, which shatters completely on impact, laminated glass holds together when struck because of its PVB interlayer. For high-risk locations, bullet-resistant and forced-entry-resistant glazing options are available. We assess threat levels and recommend appropriate protection for each location.
