Commercial Glass Installation:
How We Build Storefronts
in New Jersey

Your storefront glass does a lot more than just look good. Before a customer even walks inside your glass is already affecting how your business is perceived, how much you spend on energy, and how secure your property is.

For business owners across Bergen, Hudson, Essex, and Passaic counties, choosing the right storefront system is not just a design decision—it’s an operational one.

This guide breaks down everything you need to know: the types of systems available, what New Jersey building codes require, what impacts cost, and how to avoid expensive mistakes.

Quick Takeaways

• Energy-efficient glass can reduce heating and cooling costs by 15–30%

• Safety glass (tempered or laminated) is required in all commercial storefront doors and high-traffic areas in NJ

• Most storefront installations are completed in 1 to 3 days

• Energy upgrades typically pay for themselves within 3 to 7 years

• Thermally broken aluminum frames cost more upfront but perform significantly better long term

• ADA compliance is required for all commercial entrances

What Is Storefront Glass?

When people talk about storefront glass, they usually think about the glass panels—but the system includes much more than that. A complete storefront system includes:

• Glass panels

• Aluminum framing

• Entry doors

• Hardware (closers, locks, handles)

• Weather sealing

All of these components must work together.

One of the most common mistakes is focusing only on the glass. For example, installing high-performance insulated glass in a standard aluminum frame without thermal protection will still result in poor energy performance. The frame itself can transfer heat and cold.

A properly designed storefront affects four main things:

1. Customer perception
A clean, modern storefront creates trust. Damaged or outdated glass does the opposite.

2. Energy efficiency
Poor insulation leads to higher heating and cooling costs—especially in New Jersey’s climate.

3. Security
The right glass system can slow down or prevent forced entry.

4. Code compliance
Incorrect installations can fail inspections and create liability issues.

Types of Storefront Systems

Not all storefront systems are the same. Choosing the right one depends on your building, budget, and long-term goals.

Aluminum Storefront Systems (Most Common)

This is the most widely used system in North Jersey. It’s durable, cost-effective, and works well for most businesses.

You can choose between standard aluminum or thermally broken aluminum. The thermally broken version includes insulation inside the frame, which significantly improves energy performance.

Best for:

• Retail stores

• Offices

• Restaurants

• Strip malls

Curtain Wall Systems

Curtain wall systems are designed for larger or multi-story buildings. They provide better structural performance and allow for larger glass panels.

They are more expensive and typically not necessary for most small to mid-sized businesses.

Best for:

• Office buildings

• Large commercial facades

Frameless (All-Glass) Storefronts

These systems use minimal framing to create a clean, modern look. They offer maximum visibility and a high-end appearance.

However, they require more maintenance and are more expensive to repair if damaged.

Best for:

• High-end retail

• Showrooms

• Luxury spaces

Structural Silicone Systems

This system bonds glass directly to the structure using specialized silicone, creating a seamless exterior appearance.

Installation is more complex and must be done by experienced professionals.

Best for:

• Modern commercial buildings

• Design-focused projects

Choosing the Right Glass

The glass itself plays a major role in performance. In New Jersey’s climate, you need to balance insulation, safety, and solar control.

Insulated Glass Units (IGUs)

These are double-pane glass units with air or gas between the layers. They are standard for commercial storefronts and significantly improve energy efficiency.

Single-pane glass is outdated and should not be used in commercial applications.

Low-E Glass

Low-E (low emissivity) glass includes a special coating that reflects heat while still allowing light to pass through.

This helps keep interiors cooler in the summer and warmer in the winter. It is now standard for most commercial storefronts.

Tempered vs Laminated Glass

Both types are safety glass, but they behave differently.

• Tempered glass breaks into small pieces and is required in many storefront areas

• Laminated glass holds together when broken, offering better security

For businesses where security matters—such as pharmacies or high-value retail—laminated glass is usually the better option.

Tinted and Reflective Glass

These options help reduce glare and solar heat gain.

However, they can also reduce natural light, and some municipalities have restrictions on reflective glass, so it’s important to verify before installing.

NJ Building Codes and Requirements

Storefront installations in New Jersey must follow specific codes, mainly based on the International Building Code (IBC).

Safety Glass Requirements

Safety glass is required in:

• All doors

• Areas near doors

• Low-level glazing

• High-traffic zones

This typically means tempered or laminated glass.

ADA Requirements

All commercial entrances must meet ADA standards, including:

• Minimum 32-inch clear opening

• Low thresholds

• Accessible handles (no round knobs)

• Doors that are easy to open

Energy Code

New Jersey follows strict energy standards. Most commercial storefronts must meet requirements for:

• Insulation performance (U-factor)

• Solar heat gain (SHGC)

This usually means using insulated glass and thermally broken frames.

Installation Process

Understanding the process helps you plan better and avoid delays.

Step 1: Site Evaluation
Measurements are taken, and the structure is evaluated.

Step 2: Fabrication
Frames and glass are custom-made based on field measurements.

Step 3: Installation
The system is installed, including frames, glass, and hardware.

Step 4: Final Inspection
Everything is tested, adjusted, and approved.

Most projects are completed within 1 to 3 days once materials are ready.

Storefront Glass Cost in NJ

Costs vary depending on system type, materials, and project complexity.

Typical price ranges in North Jersey:

• Standard aluminum storefront: $45–$75 per sq ft

• Thermally broken storefront: $60–$95 per sq ft

• Frameless systems: $85–$140 per sq ft

• Curtain wall systems: $75–$150 per sq ft

Additional costs depend on:

• Glass type (Low-E, laminated, etc.)

• Site conditions

• Accessibility

• Project size

Energy Efficiency and ROI

Upgrading to energy-efficient storefront systems can reduce HVAC costs by 15–30%.

For many businesses, this translates to savings of $1,000 to $3,000 per year.

In many cases, the additional cost of better materials pays for itself within a few years.

Repair vs Replacement

Not every issue requires a full replacement.

Repair is enough when:

• Hardware is worn or broken

• Minor glass damage is present

• Seals need maintenance

Replacement is needed when:

• Glass is fogging (seal failure)

• Frames are damaged or misaligned

• Structural issues are present

Maintenance Tips

Proper maintenance can extend the life of your storefront to 20–30 years.

• Clean glass regularly with non-abrasive products

• Inspect seals and gaskets annually

• Maintain hardware (hinges, closers)

• Schedule professional inspections
