Top Commercial Door Types for 2026
Before diving into the different commercial door types, it is important to understand that the right door can make a big difference in how your business functions and looks. A well-chosen door not only provides security and durability but also improves traffic flow, energy efficiency, and the overall appearance of your restaurant, retail store, or office.
In 2026, Mankato businesses are focusing on doors that meet these needs while keeping a modern and professional look. Whether you want a store front door that welcomes customers or restaurant swinging doors that ease movement in a busy kitchen, selecting the right type of door is key for long-term success.
1. Automatic Sliding Glass Doors
Automatic sliding glass doors are one of the most common choices for high-traffic businesses like retail stores, office buildings, and supermarkets. They make entering and exiting smooth, efficient, and stress-free.
One of the biggest advantages of this door type is hands-free operation. The doors open automatically when someone approaches, which makes them convenient and more hygienic, especially in retail environments or office buildings where hundreds of people pass through daily. These doors also support energy efficiency.
Many models use insulated glass doors and tight sealing systems that help keep heat in during the winter and cool air in during the summer. This is a big help in Mankato’s seasonal weather and can reduce energy costs over time.
Their modern look also enhances your storefront. With a sleek design, they send a professional message and create a strong first impression for customers.
Key Benefits:
• Hands-free operation for convenience and hygiene
• Energy efficiency to lower heating and cooling costs

• Long-lasting options from brands like Stanley Access Technologies
2. Swinging Cafe Doors
Swinging cafe doors, also known as restaurant swinging doors, are perfect for busy restaurants, cafes, and commercial kitchens. They swing both ways thanks to double-action hinges, allowing staff to pass through without slowing down. These swing doors help keep service moving during peak hours.
Staff carrying trays or supplies can simply push through without needing to pull a handle, improving traffic flow. They also offer a classic look that can be customized to match the style of your restaurant. Whether rustic or modern, these doors can add character to your space while staying functional.
Key Benefits:
• Easy passage between rooms for staff
• Improves traffic flow in high-traffic areas
• Can be customized to match interior decor
• Suitable for restaurant doors, kitchen doors, and cafe entrances
• Durable and easy to maintain, making them a popular choice in food service
3. Commercial Steel Doors
When security is the top priority, commercial steel door installation is among the best options. They are built to withstand wear and tear, resist forced entry, and last for years. Their strength and durability make them ideal for warehouses, office buildings, and any type of business that needs dependable protection.
Many steel doors are also fire-rated, giving added safety by containing fire and smoke. With low maintenance requirements, they save money over time. Unlike wood, steel will not warp, rot, or crack, even in extreme weather conditions.
Key Benefits:
• High strength and impact resistance
• Fire-rated options available for added safety
• Low maintenance and long lifespan
• Can be used in a variety of commercial door types
• Offered by trusted local providers like Overhead Door Mankato
4. Glass Storefront Doors
For businesses that rely on attracting customers from the street, glass storefront doors are a winning choice. They make your storefront bright, open, and inviting. They provide maximum visibility, letting potential customers see inside.
This can be the deciding factor in whether someone walks in or keeps going. They are also great for attractive displays. Merchants can showcase products and promotions while letting natural light in to enhance the shopping experience.
Key Benefits:
• Visibility to attract passing customers
• Great for attractive displays and promotions
• Creates a brighter, more welcoming interior
• Customizable door frames and finishes
• Durable commercial storefront doors from companies like Storefront Doors USA
5. Fire-Rated Doors
Fire-rated doors are essential in businesses where safety compliance is important. They help slow the spread of flames and smoke, giving people time to evacuate safely. They also help with smoke control, keeping dangerous fumes contained in one area.
This is especially important in restaurants, retail stores, and office buildings. Installing fire-rated commercial doors ensures your business meets local safety codes while protecting staff and customers.
Key Benefits:

Best Commercial Security Doors: Protecting Your Business
Security is one of the most important investments a business owner can make. A weak door is an open invitation for break-ins, and no business can afford to underestimate that risk. While steel and fire-rated doors offer strong protection, this section dives deeper into the strongest commercial door options specifically for security-focused applications in Mankato.
Strongest Commercial Door Options
Grade 1 Steel Doors are the most secure option available for commercial applications. They feature heavy-gauge steel construction, reinforced lock blocks, and frames designed to resist kick-in and pry attacks. These are the standard choice for banks, pharmacies, data centers, and any business storing high-value inventory.
Hollow Metal Doors sit between standard steel and full Grade 1 commercial steel in terms of security and price. They are widely used in office buildings, storage areas, and secondary entrances. While lighter than solid steel, they are still far more secure than wood or aluminum alternatives.
Reinforced Glass Doors with Security Film are a great option for businesses that need both visibility and security, such as jewelry stores or upscale retailers. Laminated safety glass or glass treated with security film resists shattering. Paired with a high-security frame and multi-point locking system, these doors balance aesthetics with protection.
Multi-Point Locking Systems dramatically improve security regardless of door material. These systems engage multiple bolts along the door frame simultaneously, making forced entry far more difficult. Multi-point locks are compatible with most steel and heavy-duty aluminum doors.
Security Door Comparison
| Door Type | Security Level | Best For | Approx. Lifespan |
| Grade 1 Steel | Highest | Banks, pharmacies, warehouses | 30 to 50 years |
| Hollow Metal | High | Office back doors, storage rooms | 20 to 35 years |
| Reinforced Glass | Medium to High | Retail storefronts, showrooms | 15 to 25 years |
| Standard Aluminum | Medium | Low-risk retail, interior office | 15 to 20 years |
| Fiberglass | Medium | General commercial use | 20 to 30 years |
Commercial Door Sizes: What You Need to Know
One of the most overlooked aspects of commercial door selection is sizing. Getting the dimensions wrong can lead to costly modifications, installation delays, and non-compliance with ADA or local building codes. Here is a practical reference for standard commercial door sizes commonly used in Mankato businesses.
Standard Commercial Door Heights and Widths
| Door Height | Door Width | Common Use Case |
| 7’0″ (84 inches) | 3’0″ (36 inches) | Standard interior doors, ADA minimum compliant width |
| 8’0″ (96 inches) | 3’6″ (42 inches) | Main building entrances, high-traffic storefronts |
| 9’0″ (108 inches) | 4’0″ (48 inches) | Warehouse entries, double-action kitchen doors |
| 10’0″ and above | 5’0″ to 6’0″ | Double door configurations, large retail lobbies |
ADA Compliance Requirements
The Americans with Disabilities Act requires a minimum clear opening width of 32 inches for accessible doorways, with 36 inches strongly recommended. In practice, this means your door must be at least 34 to 36 inches wide to provide a 32-inch clear opening after accounting for door hardware and the frame. Businesses open to the public in Mankato are required to meet these standards.
Additional ADA door requirements to keep in mind:
• Door hardware must be operable with a closed fist, with no tight grasping or twisting required
• Maximum opening force of 5 pounds for interior doors
• Thresholds must not exceed half an inch in height
• Automatic doors are strongly recommended for high-traffic accessible entrances
Cost of Commercial Doors in 2026: What to Budget
Pricing for commercial doors varies significantly based on material, size, hardware, and installation complexity. Below are realistic 2026 cost ranges for Mankato businesses. These are general estimates and your final cost will depend on the brand, features selected, and contractor rates. Always request multiple quotes from local vendors such as Overhead Door Company of Mankato or The Window Source of Mankato.
Commercial Door Pricing by Type
| Door Type | Door Unit Cost | Installation Cost | Total Estimated Range |
| Automatic Sliding Glass | $3,000 to $8,000 | $1,500 to $3,500 | $4,500 to $11,500 |
| Commercial Steel (standard) | $800 to $2,500 | $400 to $1,200 | $1,200 to $3,700 |
| Commercial Steel (fire-rated) | $1,200 to $4,000 | $500 to $1,500 | $1,700 to $5,500 |
| Glass Storefront Door | $1,500 to $5,000 | $600 to $2,000 | $2,100 to $7,000 |
| Swinging Cafe Doors | $400 to $1,800 | $300 to $800 | $700 to $2,600 |
| Fiberglass Commercial Door | $900 to $3,000 | $400 to $1,200 | $1,300 to $4,200 |
Factors That Affect Commercial Door Cost
• Door size: larger openings require more material and labor
• Glass type: standard, insulated, tempered, laminated, or low-E coatings each carry different price points
• Frame material: aluminum, steel, or wood frames vary in cost
• Hardware: basic locksets vs. multi-point locking vs. access control systems
• Automation: adding automatic openers typically adds $1,500 to $5,000 depending on door type and width
• Fire rating: fire-rated assemblies require certified hardware throughout, raising overall cost
• Installation complexity: retrofitting an existing opening vs. framing a brand new one
Total Cost of Ownership
When comparing door options, look beyond the upfront cost. A well-insulated door can reduce your monthly energy bill noticeably depending on your building size and local energy rates. A high-quality steel door with minimal maintenance may cost more upfront but save significantly over a 20-year period compared to a cheaper door that requires frequent repairs. Consulting with a local Mankato expert will help you understand the full cost picture before committing.
Energy Efficiency: Comparing Commercial Door Options for Mankato
In Mankato’s climate, with winters dropping well below zero and summers reaching into the 90s, the energy performance of your commercial door directly impacts your monthly utility bills. This section expands on the energy efficiency topic, comparing door types and highlighting the features that matter most in our local climate.
Key Energy Efficiency Features to Look For
Insulated Cores
Steel and fiberglass doors with polyurethane foam cores offer excellent thermal resistance. Look for doors with R-values of R-10 or higher for Mankato’s climate. An insulated steel door will dramatically outperform a hollow-core metal door in winter conditions.
Insulated Glass Units
For glass doors, insulated glass units, also called double-pane glass, trap a layer of air or gas between two panes, significantly reducing heat transfer. Low-emissivity (low-E) coatings add another layer of efficiency by reflecting infrared heat.
Door Sweeps and Weatherstripping
Even the most energy-efficient door loses its performance advantage if air leaks around the frame. High-quality door sweeps along the bottom and compression weatherstripping along the sides and top are essential in Mankato’s winters.
Thermal Breaks
Aluminum frames conduct heat and cold readily. Look for aluminum-framed doors with thermal breaks, which are insulating barriers inside the frame that interrupt the metal-to-metal conductive path.
Energy Efficiency Comparison by Door Type
| Door Type | Typical R-Value | Energy Efficiency | Best Climate Application |
| Insulated Steel (foam core) | R-10 to R-17 | Excellent | Extreme cold/heat, ideal for Mankato |
| Fiberglass with foam core | R-10 to R-15 | Excellent | Cold climates, high-humidity areas |
| Insulated Glass (double-pane) | R-3 to R-5 | Good | Storefronts, office entries |
| Insulated Glass (triple-pane) | R-5 to R-8 | Very Good | High-exposure north-facing entries |
| Standard aluminum glass | R-1 to R-2 | Poor | Mild climates only |
| Hollow metal (uninsulated) | R-1 to R-2 | Poor | Interior or protected entries only |
Energy Efficiency: Retail vs. Industrial Applications
Retail spaces typically prioritize glass doors for customer-facing visibility, which means accepting a lower R-value in exchange for aesthetics. The solution is to maximize performance within the glass category: use triple-pane glass on north-facing entries, ensure tight weatherstripping, and consider automatic door openers to minimize how long the door stays open during peak traffic hours.
Industrial and warehouse applications should prioritize maximum insulation since aesthetics matter less. Insulated steel sectional doors with R-values of R-16 or higher are the standard recommendation. For frequently used loading dock doors, consider installing dock seals and shelters as an additional layer of thermal protection.
Office buildings benefit most from a combination approach: insulated steel or fiberglass doors for rear and side entrances, and high-performance insulated glass storefront systems for the main lobby entrance where first impressions matter.
Best Doors for Restaurants
Restaurant Entrance Doors
Your restaurant entrance sets the tone for the dining experience before a guest even steps inside. For most Mankato restaurants, the strongest options for the front door are:
• Glass storefront doors for upscale dining, cafes, and any restaurant that benefits from street visibility
• Aluminum-framed glass doors with low-E coating that balance aesthetics with Mankato winter performance
• Solid wood or wood-clad doors suited to rustic, fine dining, or bar concepts where warmth and character are part of the brand
Key considerations for restaurant front doors include easy-to-clean surfaces, sufficient width for wheelchair access (minimum 36 inches clear), and weather vestibules or air curtains to prevent heat loss during Minnesota winters.
Restaurant Kitchen Doors
Back-of-house is a different environment entirely. Kitchen doors need to withstand constant traffic, temperature differences, and frequent cleaning. Top choices include:
• Double-action stainless steel swinging doors, which are the gold standard for commercial kitchens
• Solid core impact-resistant doors for high-volume kitchens where staff push through with carts and supplies
• Doors with a vision panel (a small window) to prevent collisions between front-of-house and back-of-house staff
Best Doors for Retail Stores
Retail doors need to attract customers in and protect inventory when closed. The right balance of visibility, security, and energy efficiency is essential.
Main Retail Entrance Doors
• Automatic sliding glass doors are the best choice for high-traffic retail including grocery, big box, and pharmacy locations
• Frameless glass storefront doors work ideally for boutiques, specialty stores, and lifestyle brands
• Wide-opening double doors are recommended for furniture stores, home goods retailers, and any location where customers carry large items
For retail in Mankato’s outdoor strip malls and street-level storefronts, insulated glass is strongly recommended. Standard single-pane glass loses heat rapidly and can cause condensation issues that obscure your window displays.
After-Hours Retail Security
Storefront glass is a security vulnerability when the store is closed. Options to strengthen your security posture include:
• Overhead security grilles or roll-down shutters that deploy after hours
• Laminated safety glass that resists smash-and-grab attacks
• Security film applied to existing glass as a lower-cost retrofit option
• Monitored alarm systems integrated with the door frame
Best Doors for Office Buildings
Office buildings require a range of door types, from the main lobby entrance that makes a first impression to interior doors that support privacy and acoustics.
Commercial Office Exterior Doors
• Automatic sliding glass doors or swing-style full-glass entry systems work best for the main lobby
• Insulated steel or fiberglass are the right choice for secondary and emergency exit doors
• Modern commercial office doors increasingly incorporate smart access control, key fob or mobile access for employees, video intercom for visitors, and emergency override capability for safety compliance
Commercial Office Interior Doors
Key considerations for interior office doors include:
• Acoustic performance: solid-core doors with proper seals significantly reduce sound transmission between offices and meeting rooms
• Privacy glass or sidelights: frosted or tinted glass panels allow light while maintaining visual privacy
• ADA-compliant lever handles are more practical than knobs throughout a commercial office setting
Sliding Doors vs. Swing Doors for High-Traffic Areas
One of the most common questions from Mankato business owners is whether to choose sliding or swinging doors for their main entrance. Both have genuine advantages and the right choice depends on your specific situation, traffic volume, and building layout.
| Factor | Automatic Sliding Doors | Swing Doors |
| Traffic capacity | Higher, continuous flow with no wait time | Lower, one direction at a time |
| Energy efficiency | Excellent when closed, minimal air exchange | Good if self-closing hardware is installed |
| ADA accessibility | Excellent, hands-free with wide clear opening | Good, requires compliant hardware and force limits |
| Installation space | Requires overhead track and side pocket space | Requires swing clearance inward or outward |
| Security | Good, can integrate lock and access control | Excellent, stronger frame options available |
| Upfront cost | Higher ($4,500 to $11,500+) | Lower ($1,200 to $7,000) |
| Maintenance | Motor and sensor service needed periodically | Simpler, hinges, closers, and locksets only |
| Best for | Grocery, pharmacy, large retail, medical offices | Restaurants, offices, boutiques, warehouses |
For most Mankato restaurants, swing doors are the practical choice. They offer better security, lower cost, and no mechanical components to fail during a busy service. For retail stores with steady daytime foot traffic, automatic sliding doors pay for themselves over time through reduced energy loss and improved customer experience.
Commercial Doors and Hardware
The door is only as good as the hardware that secures and operates it. Skimping on commercial door hardware is one of the most common and costly mistakes business owners make. Here is an overview of the essential hardware components to pair with your commercial door.
Door Closers
Commercial door closers control the speed and force with which a door closes. They are required on fire-rated doors and strongly recommended on any exterior door in a high-traffic environment. Look for closers rated for commercial use (ANSI Grade 1) with adjustable closing speed and backcheck to prevent door damage from hard opening.
Exit Devices and Panic Hardware
Panic bars and exit devices are required by code on emergency exit doors in most commercial buildings. They allow quick egress in an emergency, since anyone can push the bar to exit. These are available in rim-mounted, concealed vertical rod, and mortise configurations depending on your door type.
Hinges
Commercial-grade hinges are significantly heavier than residential hinges. Standard commercial doors use ball-bearing hinges rated for continuous heavy use. For very heavy steel doors, heavy-duty or full-mortise ball-bearing hinges are required. Frequency-rated hinges are available for extremely high-traffic applications such as retail store or hospital entrances, rated for one million or more cycles.
Locksets and Deadbolts
For commercial applications, ANSI Grade 1 locksets are the minimum recommendation. Mortise locksets are the most durable and secure option for exterior commercial doors. For interior office doors, cylindrical locksets with privacy or passage functions are standard. Multi-point locking systems are the best choice for high-security exterior applications.
Door Stops and Holders
Door stops prevent wall damage when doors are opened forcefully. Electromagnetic door holders are useful for fire doors that need to be held open during business hours. They release automatically when the fire alarm activates, ensuring the door fulfills its fire-containment function.
