Maryland Commercial Glass and Aluminum Systems
Storefront Framing, Insulated Glass and Secure Entry Doors for Maryland Offices, Healthcare, Retail and Campus Projects
PRL Glass Systems, Inc. supports architects, designers, builders, contractors and glazing professionals on projects throughout Maryland. From Baltimore and Columbia to Germantown, Silver Spring, Frederick and Chesapeake Bay communities, we help teams choose glass and aluminum systems that suit humidity, coastal influence, traffic on main corridors and campus work. The goal is storefronts and entries that look clean, perform well and install efficiently.
With PRL you can plan each opening as a complete package: framing, doors, glass, and security glazing all from one source. We match thermally broken or impact capable systems, glass makeups and hardware to the project, then bundle everything into organized crates so crews are not chasing parts. Deliveries are scheduled around Maryland weather, site access and inspection timing to keep work moving in dense urban cores, suburbs along I 95 and smaller towns across the state.

Products Engineered for Maryland’s Climate and Codes
Thermally Broken Storefront Systems For Maryland Street Level Projects
- 250DT and 251DT thermally broken aluminum storefronts, 2 inch by 4 1/2 inch sections in 1 inch center glazed (250DT) and 1 inch offset glazed (251DT) series for Maryland office, healthcare, campus and retail work
- Pour and debridge thermal break helps reduce conductive heat through the frame, improving comfort at perimeter zones during humid summers and cooler winters along the Chesapeake and I 95 corridor
- Stock lengths typically around 24 feet in clear and dark bronze anodized finishes, with paint options available where projects call for branded or custom colors
- Frequently used with insulated or laminated glass at ground floors to address energy, noise and security needs on downtown streets and suburban retail centers
- Certifications: typically tested to ASTM E283 (air leakage), ASTM E330 (structural) and ASTM E547 / E331 (water), glass sized per ASTM E1300 and, when paired with impact glazing, can be tested to ASTM E1886 and E1996
Battle Doors And Security Entrance Systems For Maryland Financial And Public Buildings
- Security focused Glass Battle Doors for Maryland banks, schools, courthouses, government offices and urban retail where forced entry, abuse and impact are concerns
- Thermally broken aluminum frames and door leaves designed to carry 1 inch laminated security or impact glass at main entries, vestibules and security checkpoints
- Door leaf and hardware packages support larger sizes and higher weights than standard commercial doors, allowing tall, wide openings without sacrificing strength
- Compatible with access control, panic hardware and closer packages so security entrances still function smoothly for daily traffic and egress requirements
- Certifications: impact and cyclic pressure to ASTM E1886 and E1996 on appropriate glazing configurations, laminated glass to ASTM C1172 and structural design to ASTM E330
Sunny Lux Thermally Broken Aluminum Doors For Maryland Entries And Lobbies
- Slim vertical stiles around 2 1/8 inch with a thermally broken aluminum door leaf near 2 7/8 inch thick, ideal for clean, modern main entrances in Maryland office, medical and campus buildings
- Thermal break separates interior and exterior aluminum to lower heat transfer and help reduce condensation where cooled interiors meet humid summer air or colder winter temperatures
- Engineered to accept 1 1/8 inch insulated glass, including Low E, tinted or laminated makeups, so entrance doors can balance comfort, privacy and security in one system
- Available with hardware packages that include pivots or hinges, closers and lock hardware suited to high cycle commercial entries along busy streets and internal courtyards
- Certifications: tested to AAMA 1503 style thermal criteria and to ASTM E283 (air leakage), ASTM E547 (water) and ASTM E330 (structural), compatible glass standards include ASTM C1048, C1172 and IG units to ASTM E2190
Insulated And Low E Glass Units For Maryland Storefronts And Facades
- Solar control Low E glass that helps reduce heat transfer while still letting in plenty of daylight for Maryland offices, schools and retail interiors
- Hard and soft coat options tuned to reflect infrared and UV energy, helping limit solar gain and reduce fading on finishes compared to clear glass in sun exposed locations
- Stocked in common architectural thicknesses such as 1/8, 3/16 and 1/4 inch, then assembled into 1 inch insulated glass units that drop into standard commercial storefront and entrance framing
- Larger sheet sizes support taller lobby walls and storefronts in Baltimore, Columbia and suburban centers without breaking every elevation into many small lites
- Certifications: IG performance to ASTM E2190, flat glass quality to ASTM C1036, tempered glass to ASTM C1048, Low E coatings to ASTM C1376 and laminated lites to ASTM C1172 where used
Accordion Aluminum Bifold Door Systems For Maryland Restaurants And Mixed Use Projects
- Aluminum accordion bifold door systems that open patios, terraces and rooftop spaces in Maryland restaurants, taprooms and mixed use buildings, then close tight after hours or in bad weather
- Thermally broken panels and frames support better energy performance at openings that connect conditioned interiors to humid summer air and cooler shoulder seasons
- Can be glazed with tempered or laminated glass in 1/4, 1/2 and 9/16 inch thicknesses, as well as 1 1/8 inch insulated glass units where higher thermal or acoustic performance is needed near highways and rail corridors
- Panel design typically supports widths in the roughly 24 to 42 inch range, heights up to about 120 inches and panel weights near 220 pounds, giving flexibility for wide Maryland façades without overly complex steel work
- Certifications: impact resistance to ASTM E1996 and missile plus cyclic pressure testing to ASTM E1886 on impact configurations, with glass tested to ASTM C1048, C1172 and IG units to ASTM E2190
Glass Door Panic Devices And Hardware Packages For Maryland Egress Doors
- Panic hardware solutions for all glass, full framed and aluminum egress doors at Maryland schools, universities, worship facilities, arenas and office corridors
- Compatible with a range of door types and thicknesses, including typical all glass doors from about 1/2 to 3/4 inch, full framed clad doors from roughly 1/4 to 1 1/4 inch and aluminum doors from about 1/4 to 1 inch
- Tubular panic devices with slim sightlines keep glass as the visual focus while still delivering required latching, dogging and exit performance for life safety paths
- Shipped as coordinated packages with rails, devices and related hardware so inspection sensitive exits arrive complete instead of pieced together from multiple vendors
- Certifications: devices listed to UL 305 and aligned with ANSI/BHMA A156.3 Grade 1 for high cycle commercial use, intended for doors installed in paths of egress under NFPA 101, glass compatibility with ASTM C1048, C1172 and IG units to ASTM E2190

Frequently Asked Questions:
Locally Grounded, Regionally Available
Do you support projects outside Baltimore, Columbia and Silver Spring?
Yes. PRL works with large metros, mid sized cities and small towns throughout Maryland. We group storefronts, doors, glass and hardware into labeled crates and move everything through regional carriers. That way coastal and inland jobs both get fast delivery and complete packages that are easier to unload, stage and install.
What systems handle Maryland humidity, coastal influence and mixed seasons best?
Most projects start with thermally broken storefront framing and insulated Low E glass on main elevations, then use Sunny Lux or security focused entrance doors at key openings. In downtown, coastal or higher risk areas, laminated or impact glass is often used at doors and ground floor lites. That mix helps manage heat gain, glare and street level exposure while staying practical for Maryland contractors and glazing crews.
How do you approach school and public safety projects in this region?
We combine thermally broken storefronts with insulated and laminated glass, then use Battle Doors or other security focused entrances at main doors, office areas and key corridors. For Maryland schools, campuses and civic buildings, we coordinate glass thickness, hardware and framing early so drawings stay clear and the final package supports daily traffic, access control and regional safety priorities.
