Storefront Glass Options for Los Angeles Businesses
Choosing the right glass for your commercial storefront isn’t just about looks. It affects security, energy costs, code compliance, and how your business presents itself to customers walking by.
This guide breaks down every major storefront glass type used in commercial applications — what each one is, when to use it, and the pros and cons. We also cover framing systems and the code requirements that apply to commercial storefronts in Los Angeles.
The LA Glass Company has been installing and replacing commercial storefront glass since 2008. Gustavo Ramos, our owner and a third-generation glazier, has specified and installed every type of glass listed here. When you need glass storefront installation in Los Angeles, this is the background we bring to the job.
The Most Common Types of Storefront Glass
1. Clear Tempered Glass
Tempered glass is the standard for commercial storefronts. It’s 4–5x stronger than annealed (standard) glass and — critically — it’s required by code for most commercial applications.
When to use it: Virtually every standard storefront, entry door, sidelite, and large glazed panel.
Pros:
- High impact resistance
- Breaks into small, rounded pebbles rather than sharp shards (safety glazing)
- Cost-effective for large areas
- Maximum visibility and light transmission
Cons:
- Cannot be cut or modified after tempering — must be fabricated to size
- Does not provide significant sound attenuation on its own
2. Tinted Glass
Tinted glass is clear tempered glass with a color introduced during manufacturing — bronze, gray, blue, or green are the most common commercial tints.
When to use it: Businesses that want to reduce heat gain, manage glare, or create a particular aesthetic — retail, restaurants, office lobbies.
Pros:
- Reduces solar heat gain (cooling cost savings in LA’s climate)
- Reduces glare for employees and customers near windows
- Adds visual interest and branding opportunity
Cons:
- Reduces natural light inside
- Slightly higher cost than clear tempered
- Dark tints can make the interior look uninviting at night
3. Frosted and Decorative Glass
Frosted glass is either acid-etched or sandblasted to create an opaque or translucent surface. Decorative glass includes patterned, silk-screened, or digitally printed options.
When to use it: Medical offices, financial services, law firms, salons, or any business where partial privacy is desired while maintaining light transmission.
Pros:
- Privacy without blocking natural light
- Professional, polished appearance
- Can incorporate logos or branding elements (via silk-screen or digital print)
Cons:
- More difficult to clean than clear glass
- Decorative and printed options cost significantly more
- Not suitable where full visibility is important (retail display windows)
4. Laminated Glass
Laminated glass consists of two or more layers of glass bonded together with a polyvinyl butyral (PVB) interlayer. If broken, the interlayer holds the glass together rather than allowing it to fall out.
When to use it: High-security retail, jewelry stores, banks, cannabis dispensaries, storefronts in high-crime areas, or anywhere hurricane or forced-entry resistance is needed.
Pros:
- Significantly higher break-in resistance than standard tempered
- Holds together when broken — no immediate exposure of the opening
- Reduces sound transmission (better than tempered alone)
- Required by code in some overhead glazing applications
Cons:
- Higher cost than standard tempered
- Heavier — may require frame upgrades
- Slight visual distortion at certain angles with some PVB grades
5. Insulated Glass (Double Pane / IGU)
Insulated Glass Units (IGUs) consist of two panes of glass separated by a sealed air or gas (argon, krypton) space. This is the commercial equivalent of a double-pane window.
When to use it: Any business that wants to reduce heating and cooling costs — restaurants, offices, retail in climate-controlled environments, or buildings with large glass exposures.
Pros:
- Dramatically reduces heat transfer and energy costs
- Reduces condensation on the interior glass surface
- Improves interior comfort near glass walls
Cons:
- More expensive upfront than single-pane systems
- Requires compatible framing (thicker glazing pocket)
- Seal failure (fogging between panes) requires full unit replacement
6. Low-E Glass
Low-E (low emissivity) glass has a microscopically thin metallic coating that reflects infrared heat while allowing visible light through. It’s often used in IGUs for maximum energy performance.
When to use it: Any commercial project where energy efficiency is a priority — LEED projects, Title 24-compliant new construction, large glass facades in full sun.
Pros:
- Reduces solar heat gain in summer, retains heat in winter
- Helps meet California Title 24 energy code requirements
- Minimal visible impact on light transmission (modern coatings are nearly invisible)
Cons:
- Higher material cost
- Some coatings affect mobile signal (relevant for retailers with mobile POS systems)
- Coating type must be specified correctly for climate and orientation
7. Wire Glass
Wire glass has a metal mesh embedded in the glass. It was historically used as a fire-rated glazing option. However, its use has declined significantly.
When to use it: Rarely specified for new commercial storefronts. May still be found in older buildings. For fire-rated applications, newer ceramic or specialty tempered products typically replace it.
Pros:
- Holds together in a fire (limits spread of flames and smoke)
Cons:
- Lower impact resistance than tempered
- Scratches easily and looks dated
- No longer accepted as safety glazing in many code jurisdictions
- Better fire-rated alternatives are now available
8. Herculite Doors (All-Glass Entrances)
Herculite doors — also called patch-fitting doors or all-glass entrances — are large panels of heavy tempered glass (typically 3/8″ or 1/2″ thick) hung on pivot or patch hardware with no surrounding frame.
When to use it: Upscale retail, hotel lobbies, luxury office buildings, and anywhere a high-end, frameless aesthetic is required.
Pros:
- Premium visual appearance — maximum transparency
- Durable and long-lasting when properly specified
- Makes a strong first impression
Cons:
- Highest cost of any standard storefront entry option
- Hardware (pivots, patches, closers) requires specialized installation
- Broken panel requires complete replacement — no reglaze
Framing Systems: Aluminum vs. Steel
Aluminum Storefront Framing
Aluminum is the dominant material for commercial storefronts in Los Angeles. It’s lightweight, corrosion-resistant, and available in a wide range of finishes — clear anodized, dark bronze, black, and custom powder coat.
Best for: Most retail, office, and restaurant storefronts. Standard commercial construction.
- Lower installed cost than steel
- Excellent corrosion resistance (important near the coast)
- Wide range of manufacturers and profiles
- Thermally broken versions available for energy compliance
- Easier to source replacement parts
Steel Storefront Framing
- Significantly higher cost than aluminum
- Requires regular maintenance to prevent rust (even galvanized or coated systems)
- Provides a distinctive, premium aesthetic
- Stronger — allows larger unsupported spans
Code Requirements for Commercial Storefronts in Los Angeles
California has some of the most stringent building codes in the country. Here’s what matters most for commercial storefront glazing.
Safety glazing (tempered or laminated) is required:
- All glass in doors and within 24 inches of a door edge
- Glass panels within 18 inches of the floor
- Glass in railings and guards
- Any glazed panel in a hazardous location as defined by CBC Chapter 24
Tempered glass must be labeled. All safety glazing in California must bear a permanent label identifying the manufacturer, type, and safety glazing standard (ANSI Z97.1 or CPSC 16 CFR 1201).
Title 24 Energy Code governs U-factor, Solar Heat Gain Coefficient (SHGC), and visible transmittance for commercial glazing. In most LA climate zones, exterior glazing must meet minimum performance values — Low-E coatings or insulated units are often required to comply.
ADA compliance applies to door hardware, thresholds, and clearances — not the glass type itself, but it affects how the overall storefront system is specified.
Fire-rated glazing is required at specific locations near property lines and in fire walls — your architect or building department will specify this. Standard tempered glass does not qualify as fire-rated.
When in doubt, pull permits and have the glazing specified by a licensed contractor. The LA Glass Company works with building departments across LA County and can advise on compliance for your project.
How to Choose the Right Glass for Your Storefront
Ask yourself these questions:
- Where is the storefront facing? South and west exposures benefit most from tinted or Low-E glass.
- What’s your security concern? High-crime area or high-value merchandise → laminated glass.
- What’s your energy situation? High cooling bills → insulated or Low-E.
- What’s your aesthetic? Open, transparent → clear tempered. Premium/frameless → Herculite. Private → frosted.
- What’s your budget? Clear tempered in aluminum framing is the most cost-effective baseline. Every upgrade adds performance and cost.

FAQ
Q: What type of glass is required for commercial storefronts in California?
A: California Building Code requires safety glazing (tempered or laminated) in most commercial storefront applications, including all glass in and near doors, low glass panels, and hazardous locations. All safety glazing must be permanently labeled.
Q: What's the difference between tempered and laminated glass for a storefront?
A: Tempered glass breaks into small, safe pebbles and provides excellent impact resistance — it’s the standard for most storefronts. Laminated glass holds together when broken (the interlayer keeps shards in place), making it better for security applications where keeping the opening sealed after a break is important.
Q: Does storefront glass in LA need to meet energy codes?
A: Yes. California Title 24 sets minimum performance requirements for commercial glazing including U-factor and Solar Heat Gain Coefficient. In many cases, Low-E glass or insulated units are needed to comply, especially for south- and west-facing exposures.
Q: How do I choose between aluminum and steel framing for my storefront?
A: Aluminum is the practical choice for most commercial storefronts in LA — lower cost, corrosion-resistant, wide availability. Steel is used when the design requires slim sightlines or a specific architectural look. We can advise based on your building and budget.
