All glass in shower and bathtub enclosures must be tempered safety glass. This includes shower doors, fixed panels,
Glass panels with a bottom edge within 18 inches of the floor or walking surface must be tempered. This commonly applies to sidelights, floor-level windows,
Glass adjacent to stairs, landings, and ramps requires tempered safety glass. This includes windows along staircases, glass railings,
All glass used in railings, guards, and balustrades must be tempered or laminated safety glass.
Glass table tops should be tempered for safety, especially in homes with children. While not always code-required,
Glass Comparison
Tempered glass is the standard for safety applications. We install it in every location where building codes require it.
Regular glass is appropriate for standard window locations but must be replaced with tempered glass in safety-critical areas.
How It Is Made
Tempered glass starts as regular annealed glass that is cut, drilled, edged, and shaped to the exact final dimensions. Once all fabrication is complete, the glass is heated to approximately 1,200 degrees Fahrenheit in a tempering furnace. The heated glass is then rapidly cooled using high-pressure air jets in a process called quenching.
This rapid cooling creates a state of internal tension -- the outer surfaces of the glass cool faster and compress, while the interior remains in tension. This internal stress pattern is what makes tempered glass four to five times stronger than untreated glass and causes it to break into safe granular pieces rather than dangerous shards. It is also why tempered glass cannot be modified after tempering -- any cut or drill hole releases the internal tension and shatters the entire panel.
Because tempered glass cannot be trimmed, drilled, or adjusted on site, every measurement must be exact before fabrication begins. Even a 1/16-inch error can make the panel too large for the opening or leave visible gaps. This is why we always measure in person rather than relying on customer-provided dimensions.
Our technicians use precision measuring tools and check each dimension multiple times. For shower doors and railing panels where hardware alignment is critical, we measure the hardware positions and transfer them to the glass specifications before fabrication. This attention to precision is the difference between a panel that fits perfectly and one that does not.
Thickness Guide
Choosing the right thickness is critical for safety and code compliance. Here is what we recommend for the most common tempered glass applications in the DMV.
Used for picture frame glass, small cabinet inserts, and lightweight display applications. Not suitable for structural or safety-critical applications. The thinnest tempered glass option available.
Common for storm door glass inserts, small cabinet doors, and display case shelves. Provides basic safety protection in low-impact applications. Lighter weight makes it suitable for small openings.
The standard thickness for glass table tops, glass shelving, window glass near doors and floors, and general code-required safety glass applications. The most commonly ordered thickness for residential safety glass.
An intermediate thickness used for larger table tops, heavier-duty shelving, and some shower door applications. Provides additional strength for larger panels and higher-impact locations.
The standard thickness for most frameless shower doors, shower enclosure panels, and interior glass railing panels. Provides excellent strength and stability for daily-use applications in wet environments.
Used for heavy-duty shower doors, exterior railing panels, balcony guards, and applications requiring maximum strength. Required by code for many exterior railing applications and high-impact locations.
Finishing Options
Edge treatment must be completed before the glass is tempered. We offer several edge options depending on your application and aesthetic preferences.
The most common edge treatment for exposed tempered glass. The edge is ground flat and polished to a smooth, glossy finish. Used on table tops, shower doors, and any application where the glass edge is visible. Provides a clean, professional appearance.
A slightly rounded edge profile that is ground and polished smooth. The gentle curve makes the edge comfortable to touch and reduces the risk of chipping. Common on glass shelves, table tops, and railing panels.
An angled cut along the edge of the glass that creates a decorative border. Beveled edges catch and refract light, adding visual interest. Popular for mirrors, decorative table tops, and display applications.
The most economical edge treatment. The cut edge is lightly sanded to remove sharpness but is not polished to a glossy finish. Suitable for glass that will be inserted into a frame, channel, or gasket where the edge is not visible.
Inspection Ready
Home inspectors in Virginia, Maryland, and DC regularly flag non-tempered glass in locations where building code requires safety glass. This is especially common in homes built before the 1970s when tempered glass requirements were less comprehensive. Older homes may have regular annealed glass in shower enclosures, near floor-level windows, beside doors, and along staircases.
When a home inspection identifies safety glass violations, the seller or buyer typically needs to correct them before closing. We handle these correction projects frequently and can usually complete all required tempered glass replacements within one to two weeks, including measurement, fabrication, and installation.
Every replacement panel we install carries the required safety certification label (CPSC 16 CFR 1201 or ANSI Z97.1) permanently etched into the glass corner, providing documentation that the code requirement has been met. This label is what inspectors verify during their review.
Code Requirements
Understanding where tempered glass is required by Virginia, Maryland, and DC building codes helps you stay compliant and keep your property safe.
All glass in shower and bathtub enclosures must be tempered or laminated safety glass per IRC Section R308.4. This includes shower doors, fixed panels, and any glass within 60 inches of the shower floor. We replace non-compliant shower glass daily across the DMV.
Any glass panel in a door -- including sliding doors, French doors, patio doors, and storm doors -- must be tempered safety glass. This applies to both interior and exterior doors. Sliding glass door panels are one of our most common tempered glass replacements.
Glass panels adjacent to doors (sidelights) and above doors (transoms) are considered hazardous locations because of their proximity to foot traffic and door operation. Both require tempered or laminated safety glass per building code.
Windows with a bottom edge less than 18 inches above the floor are classified as hazardous locations. These commonly include basement egress windows, sunroom panels, and floor-to-ceiling window walls. All glass in these locations must be tempered.
Glass adjacent to stairs, ramps, and landings is required to be safety glass because falls in these areas are more likely and more dangerous. The hazardous area extends to 36 inches from the walking surface and 60 inches from the bottom of the stairway.
Glass used as a structural railing or guard -- on balconies, mezzanines, stairways, and decks -- must meet specific safety and load requirements. Most applications require tempered glass, and some require laminated or laminated-tempered glass depending on the height and configuration.
Glass Comparison
Tempered glass and laminated glass are both classified as safety glass, but they protect differently. Tempered glass is four to five times stronger than annealed glass and breaks into small, relatively harmless granules. Laminated glass consists of two sheets of glass bonded to a plastic interlayer (typically PVB) -- when broken, the glass fragments adhere to the interlayer and the panel stays in the frame.
For most residential applications in the DMV -- shower doors, door glass, low windows -- tempered glass is the standard and most cost-effective choice. Laminated glass is preferred for overhead glazing (skylights), security applications, and noise reduction. Some locations require laminated-tempered glass, which combines both technologies. We help you select the right type for each application.
Annealed glass -- sometimes called standard or float glass -- is the basic glass used in many older windows and mirrors. When annealed glass breaks, it shatters into large, sharp shards that can cause serious injury. This is why building codes require tempered glass in hazardous locations. Tempered glass costs more than annealed glass, but the safety benefit is significant -- its break pattern of small granules dramatically reduces the risk of laceration injuries.
A critical difference between tempered and annealed glass: tempered glass cannot be cut or drilled after tempering. All holes, notches, and edge work must be completed before the glass enters the tempering furnace. This is why accurate measurements are essential -- if a tempered panel does not fit, it cannot be trimmed on site. Our measurement process accounts for this, and we verify every dimension before fabrication begins.
How do you know if your existing glass is tempered? Look for a small etched label in one corner of the glass. Tempered glass manufactured after 1977 is required to carry a permanent mark indicating the manufacturer and the safety standard (CPSC 16 CFR 1201 or ANSI Z97.1). The label is typically acid-etched or sandblasted into the glass surface and cannot be removed.
If you cannot find a label, other clues can help. Tempered glass viewed through polarized sunglasses may show a subtle pattern of dark spots or lines (the stress pattern from tempering). If the glass is already broken and you see small, roughly cubic granules rather than large shards, it was tempered glass. When in doubt, we can inspect your glass and determine whether it is tempered, laminated, or annealed.

Applications
In residential settings, tempered glass is most commonly needed for shower enclosures, door glass (sliding, patio, French, and entry doors), glass table tops, low windows, stairway windows, and glass railings. Bathroom renovations are one of our most frequent tempered glass projects -- custom shower doors and enclosures require precisely measured and fabricated tempered panels with holes for hinges and handles.
We also fabricate residential tempered glass for fireplace screens, cabinet doors, pet doors, glass partitions, and furniture tops. For homeowners renovating kitchens, tempered glass backsplashes provide a seamless, easy-to-clean surface behind ranges and sinks. Each residential project begins with an in-home measurement to ensure perfect fit and code compliance.
Commercial properties across the DMV use tempered glass in storefronts, office partitions, conference room walls, reception desks, display cases, and building entrances. Commercial building codes often have stricter requirements than residential codes, particularly for glass in high-traffic areas, at building entrances, and adjacent to sidewalks and parking areas.
We work with property managers, general contractors, architects, and business owners on commercial tempered glass projects of all sizes. From replacing a single broken panel in an office door to fabricating custom tempered glass for an entire storefront renovation, we provide the measurement precision, fabrication expertise, and installation quality that commercial projects demand. We understand commercial timelines and can coordinate installations during off-hours to minimize business disruption.
Not every tempered glass need fits a standard size. We fabricate custom tempered glass panels to any specification -- unusual shapes, specific thicknesses, custom tints, low-E coatings, ceramic frit patterns, and specialty finishes. Custom orders include precise hole drilling for hardware, notch cutting for clearances, and polished or beveled edges.
Our custom fabrication process begins with detailed field measurements. We create a fabrication drawing with all dimensions, hole locations, edge treatments, and specifications. You approve the drawing before we begin fabrication. Standard custom tempered glass turnaround is 3-7 business days depending on complexity. For urgent needs, expedited fabrication may be available at an additional charge.
