Can a glass door be fire rated? Yes, it can. Fire rated glass doors for homes and condos pair tested glass with a certified frame. As a result, an opening that needs a fire rating does not have to be a solid slab of wood or steel. This guide explains how these doors work. It also covers what the ratings mean and what to check before you specify one.

Can You Have a Fire Door With Glass?

Yes. Ordinary glass cracks and falls out under heat. For that reason, a fire door with glass uses glass that has been tested for fire exposure. The frame goes through the same testing. Together, the glass, frame, and hardware form one assembly. That assembly carries a listing and a label under standards such as UL 10C and NFPA 252. Inspectors look for that label on site.

However, regular glass in a rated opening generally does not meet code. This is true even when the frame itself has a rating.

Fireproof vs. Fire Rated: What the Terms Mean

Many people search for a fireproof glass door. In fact, no door is truly fireproof. A fire rating measures time. It tells you how long a tested assembly can hold back fire and smoke. Common ratings are 45, 60, and 90 minutes. After that time, the door is expected to fail like any other. That is why codes and labels say fire rated, not fireproof.

Fire rated glass also comes in two broad types. First, fire protective glass blocks flames and smoke. However, it lets heat pass through. For this reason, codes limit where it can go and how large it can be. Second, fire resistive glass also limits heat transfer. As a result, it allows larger glass areas. Your wall construction and local code decide which type an opening needs. The Authority Having Jurisdiction (AHJ) makes the final call for your building.

Fire Ratings: 45, 60, and 90 Minutes

The rating you need depends on three things. These are the wall construction, the use of the space, and local code. For example, corridors, elevator lobbies, stairwell enclosures, and dwelling unit entries often call for different ratings. Therefore, confirm the rating before you order. Ask your architect, fire protection engineer, or local building department. Our guide to fire door ratings from 20 to 90 minutes explains how ratings are assigned.

Frames, Swing Types, and Sizes

Fire rated glass doors come in steel and aluminum frames. They also come as hinged or pivot doors. Apex Fire Doors supplies Tecfire’s certified systems:

• SteelFire STB80 (steel frame): hinged or pivot doors. The maximum door height is 98¾ inches. The maximum single leaf width is 52¾ inches.
• AluFire AS85 (aluminum frame): hinged doors rated 45 or 60 minutes. Finishes include powder coat and anodized, with stainless steel and wood effect options.

Both systems carry UL 10C and UL 10B listings. They also test to NFPA 252 and meet ANSI Z97.1 glazing safety requirements. In addition, Intertek lists and labels them, and they pass hose stream testing. See our fire rated glass systems for sizes and configurations.

Making Fire Rated Glass Doors for Homes Part of the Design

Fire rated glass no longer has to look like an office door. Clean, square frame profiles, custom finishes, and full-height glass keep sightlines open. As a result, light moves through the home. For apartment entries, see how this works in a luxury foyer.

Some owners and designers want the glass itself to carry the design. For them, the Iberi Signature Series adds a custom artistic glass design to a Tecfire fire rated door system. Every door is designed for one client and one home, so no two are alike. In Florida, the Iberi Signature Series is for interior applications only. In other states, exterior availability depends on local wind load, water infiltration, and impact code requirements.

Interior and Exterior Use

In Florida, these fire rated glass door systems are for interior openings. Exterior openings in Florida need hurricane impact approval under the Florida Building Code. For that reason, confirm the location of the opening before you specify any door. Other states may not require that approval. There, exterior use depends on local code and on wind load and water pressure requirements. We can confirm availability project by project. If you manage a condo or multifamily building, read our guide to condo fire door compliance in South Florida.

Keeping a Fire Door Compliant After Installation

A fire door only protects the building if it keeps working. That is why NFPA 80 requires annual inspection and testing of fire door assemblies. You must keep the documentation on site. Our Miami-Dade fire door inspection checklist shows what inspectors look for. In addition, our page on fire door technology and certifications explains each listing and label.

Frequently Asked Questions

Can a glass door be fire rated for a home?

Yes. Fire rated glass door systems pair tested glass with a certified frame. The whole assembly carries a listing and a label. Ratings of 45, 60, and 90 minutes are available, depending on the system and configuration.

Is there such a thing as a fireproof glass door?

No. No door is fireproof. Instead, doors are fire rated. A tested assembly resists fire and smoke for a set time, such as 45, 60, or 90 minutes.

Do fire doors with glass have to look industrial?

No. Clean frame profiles, custom finishes, and full-height glass fit a residential design. In addition, the Iberi Signature Series offers custom artistic glass designs.

Can the Iberi Signature Series go on exterior doors?

Not in Florida. Hurricane impact approval requirements limit it to interior use there. In other states, exterior availability depends on local wind load, water infiltration, and impact code requirements. Confirm with us before you specify.

Who decides which fire rating my opening needs?

The Authority Having Jurisdiction (AHJ) makes the final call. It bases the decision on the wall construction and the use of the space. Confirm the rating with your architect, fire protection engineer, or local building department before you order.

Miami-Dade Fire Door Inspection Checklist for Property Managers

This fire door inspection Miami checklist walks property managers through what Miami-Dade Fire Rescue’s Fire Prevention Division checks during the annual review tied to your building’s Life Safety Operating Permit. NFPA 80 sets that requirement, and the Florida Fire Prevention Code (8th Edition) references it for inspecting and maintaining rated door assemblies. Use the four checklists below to see what inspectors check, what records you need, and what’s specific to Miami-Dade before an inspector shows up.

Checklist 1: Before the Inspector Arrives

• ☐ Every rated door closes and latches fully on its own, with no one pushing it shut
• ☐ Labels on the door and frame stay visible and legible, and no one has painted over them
• ☐ No one has added a chain, slide bolt, or extra lock to any rated opening
• ☐ Corridor and stairwell doors haven’t been propped open with a wedge or hold-open device
• ☐ Anyone doing recent hardware, lockset, or access-control work on a rated door knew it could void the label

Checklist 2: The Physical Assembly (What NFPA 80 Requires the Inspector to Verify)

• ☐ Door and frame labels stay present and legible
• ☐ The door or frame has no unauthorized holes, cuts, or breaks beyond factory-approved hardware prep
• ☐ Glazing and glazing beads stay intact and securely fastened, not loose or cracked
• ☐ Door, frame, hinges, and hardware stay aligned, undamaged, and free of missing or broken parts
• ☐ The gap between door and frame falls within tested tolerances, checked with a gauge
• ☐ The door closer brings the door fully shut and latched, without assistance
• ☐ On door pairs, the coordinator makes the leaves close in the correct order
• ☐ No auxiliary hardware interferes with normal closing and latching
• ☐ No field modification would void the fire label
• ☐ Gasketing and edge seals stay present, continuous, and the correct type where required
• ☐ Signage on the door face doesn’t cover the label or interfere with operation

Checklist 3: Documentation the Fire Prevention Division Will Ask For

• ☐ A written inspection record for every fire door assembly, signed by whoever performed it
• ☐ At least 3 years of inspection history on file, matching NFPA 80’s minimum retention period
• ☐ Acceptance test records from installation, kept for the life of the assembly
• ☐ Your current Life Safety Operating Permit, or proof you’ve already scheduled an inspection
• ☐ A response plan for a Life Safety Complaint, since the Division must investigate within 3 working days of receiving one

Checklist 4: Miami-Dade-Specific Items Most Checklists Miss

• ☐ Confirm whether your building falls inside the 25-year (then every 10 years) structural recertification window: this applies to condos or co-ops three stories or taller within three miles of the coast
• ☐ Egress doors often get a second look during that recertification process
• ☐ Outside that coastal band, confirm your building’s 30-year (then every 10 years) recertification timeline instead
• ☐ Check hinges, closers, and hardware in coastal buildings more often than the annual minimum, since salt air corrodes them faster than inland installations
• ☐ A door that lost its label to repainting or damage needs field re-labeling or replacement before it can pass; a note that “it used to be rated” won’t satisfy an inspector

Fire Door Inspection Miami: Where Doors Usually Fail

Two problems show up more than anything else across Miami-Dade properties. Heat props doors open until the closer stops working correctly, and owners add hardware for “extra security” that voids the label without anyone realizing it. Corridors where someone painted over the label come in a close third.

If Something Doesn’t Check Out

A door that’s aged out, lost its label, or suffered damage from hardware modifications is usually faster to replace than to field-repair. Apex supplies code-compliant hollow metal and solid core wood fire doors, handles hardware repair and replacement, and covers interior and exterior fire-rated glass. That means a flagged opening can get back into compliance before your Life Safety Operating Permit is at risk. Work with a supplier who knows Miami-Dade code from the start, and contact Apex Fire Doors to get ahead of your next inspection.

Fire Door Ratings Explained: 20 to 90 Minutes (and What Florida Code Requires)

Fire doors are rated by how long they can contain fire and smoke before failing, not by how thick or heavy they look. Understanding what those minute ratings actually mean, and which one your building needs, is the difference between passing inspection on the first try and re-ordering doors mid-project. This guide breaks down the ratings, the testing standards behind them, and how Florida Building Code determines which rating applies to your opening.

How Fire Doors Are Actually Tested

Manufacturers test and label every fire-rated door assembly sold in the U.S. to one of two standards: NFPA 252 or UL 10C. Both expose a full door assembly (door, frame, hardware, and glazing together) to a standardized fire inside a furnace and measure how long it holds before flame or excessive heat passes through.

UL 10C is the stricter of the two. After the first 5 minutes, it adds positive pressure inside the furnace. That forces the door to resist both heat and pressure for the entire rated duration, closer to how a real fire behaves in an enclosed building. Most manufacturers, including Apex, test to UL 10C because it satisfies both standards at once.

Fire Door Ratings, Minute by Minute

• 20-Minute Rating: The minimum protection level, typically required for corridor doors and openings in 1-hour rated partitions in sprinklered buildings.
• 45-Minute Rating: Common in office corridors and moderate-hazard commercial spaces where a 1-hour wall assembly is present.
• 60-Minute Rating: Used for higher-hazard areas and larger commercial spaces, including many hospital and multi-family applications.
• 90-Minute Rating: Required for openings in 2-hour fire walls, including stairwells, shafts, and separations between building sections. This is the standard for most high-rise commercial and luxury residential foyer applications in South Florida. It’s also the highest door rating available in our IBERI Signature Series.
• 120-Minute Rating: Available in IBERI fixed glass panels (non-operable openings), not doors. Used for higher-hazard interior separations where the opening doesn’t need to swing.
• 180 to 240-Minute Ratings: Reserved for the most critical separations, such as industrial facilities, hazardous storage, and major structural fire walls. These ratings are typically achieved with steel or masonry assemblies rather than glass.

The Rule Most People Miss: Your Door Rating Depends on Your Wall Rating

Florida follows the International Building Code (IBC). IBC Table 716.1 sets a simple relationship that a lot of specifiers miss until an inspector flags it. The required door rating is generally 75% of the wall rating it’s installed in. A 2-hour fire wall requires a 90-minute door. A 1-hour corridor wall typically requires a 20 or 45-minute door. The exact rating depends on occupancy type and whether the building has sprinklers. Getting this wrong is one of the most common reasons fire door installations fail inspection in Miami-Dade and Broward County. The door itself may be perfectly rated, just for the wrong wall.

Material and Construction

The rating is only half the picture. The material has to match the application too:

• Steel (Hollow Metal): The standard for commercial and industrial applications where durability and high fire ratings matter most. See our Hollow Metal Fire Doors.
• Solid Core Wood: Fire-rated wood doors use a mineral or honeycomb core to hit the same ratings as steel, with a warmer architectural look for offices and multi-family lobbies. See our Solid Core Wood Doors.
• Fire-Rated Glass, Interior: Our IBERI Signature Series is Apex’s own design line for high-end interior foyers, custom-designed by us and manufactured using certified Tecfire fire-rated glass technology. The IBERI design comes in 45, 60, and 90-minute door ratings, plus fixed glass panels rated up to 120 minutes. Both glass and aluminum-framed configurations are available. Tecfire’s Florida certification covers interior applications only, so IBERI is specified for interior openings.
• Fire-Rated Glass, Exterior: Exterior glass openings carry different fire, impact, and hurricane-code requirements than interior openings. For these applications, Apex sources through TGP (Technical Glass Products), one of the most widely specified fire-rated glass manufacturers in North America. See our Fire Rated Glass Systems for both lines.

Hardware That Has to Be Rated Too

A fire door assembly is only as good as its weakest component. Ratings-critical hardware includes:

1. Intumescent Seals: Expand under heat to close gaps around the door before flame can pass through.
2. Fire-Rated Hinges: Rated to hold under high heat without failing.
3. Automatic Closers: Ensure the door fully closes and latches after every use. An unlatched fire door has no rating at all.
4. Fire-Rated Glazing: Any glass in a rated door must carry its own fire rating matching the door assembly.

Choosing a Fire-Rated Door Supplier in South Florida

• Certification: Confirm UL or Intertek labeling on every unit, not just a general claim of “fire-rated.”
• Local code experience: A supplier familiar with Miami-Dade and Broward inspection processes will catch wall/door rating mismatches before installation, not after.
• Product range: Steel, wood, and glass options under one supplier simplifies coordination across a project with mixed door types.
• Installation support: A correctly rated door can still fail inspection if installers get it wrong, whether that’s bad gap tolerances or the wrong hardware.

Fire door ratings aren’t just a compliance checkbox. They’re what actually contains a fire long enough for a building to evacuate safely. Match your door rating to your wall assembly, and confirm your hardware carries the same rating as the door. Work with a supplier who knows South Florida code from the start. Contact Apex Fire Doors for a code-compliant fire door specification for your next project.

Fire-resistant doors form an important part of a building’s safety features. They protect occupants and help guard against fire hazards. Fire-resistant doors act as a barrier that stalls the movement of flames and smoke, and they often play a key role in saving lives and property. This guide covers fire-rated metal doors: their advantages, types, and why selecting the right door matters for any facility. If your building is in Miami or elsewhere in South Florida, we also point to the code and inspection rules that apply.

What Are Fire Resistant Doors?

Fire-resistant doors resist extreme heat from fire for a set period. That gives occupants a safe exit route while containing the spread of fire and smoke. These doors matter in both commercial and residential buildings, since they maintain the integrity of fire-rated walls and stop flames from spreading further.

Manufacturers build fire-resistant doors from materials that resist extremely high temperatures. Each door gets a fire-resistance rating that shows how long it can withstand fire exposure before failing. That rating matters for building-safety compliance, and building codes often require it. For a full explanation of what each rating means, read our guide to fire door ratings from 20 to 90 minutes.

Types of Fire-Rated Doors

1. Hollow metal fire rated Doors

Hollow metal fire-rated doors are the most common fire-rated doors in commercial buildings. Manufacturers build these doors with a steel exterior and fill the core with fire-resistant material to boost fire resistance. Apex supplies hollow metal fire doors in 20, 18, 16, or 14 gauge steel, rated from 90 minutes up to 3 hours, with welded frames for masonry or knock-down frames for drywall.

Advantages

• Durability: It holds up well in high-traffic areas prone to impacts, making it one of the toughest door types available.
• Cost-Effective: Compared to other fire-rated doors, hollow metal doors cost less and strike a reasonable balance between performance and price.
• Maintenance: Hollow metal fire-rated doors are easy to maintain, and most get painted or finished to match the building’s aesthetic.

2. Steel fire-rated doors

Steel doors are part of the hollow metal door family, but they deserve a separate place due to their specialized characteristics. Manufacturers make these entirely of steel, which makes them more robust and secure.

Advantages

• Security: A steel fire door’s strength makes it hard to breach by forced entry, which is why it fits high-security places.
• Long-Lasting: A steel door lasts longer and needs less maintenance than a wood door.
• Fire Resistance: They offer high fire-resistance ratings, so builders use them primarily in critical safety applications.

3. Aluminum and glass fire-rated doors

Aluminum framed systems with fire rated glass suit spaces where light and appearance matter, such as lobbies and residential foyers. They are lightweight, resist corrosion in humid climates, and come in many finishes. Apex supplies steel and aluminum framed fire rated glass systems, and our Iberi Signature Series adds custom artistic glass designs. For a closer look at the luxury residential use case, see our article on interior fire rated glass doors for luxury foyers.

Advantages

• Appealing: Aluminum and glass systems add sophistication, since finishers can color and style them for a modern look.
• Lightweight: These frames weigh less than steel, so crews can handle and install them easily.
• Corrosion resistance: Aluminum hardly rusts or corrodes, which makes it a good fit for places with high humidity.

Benefits of Fire-Rated Doors

1. Enhanced Safety

The most important advantage of fire-rated doors is safety. By stopping fire and smoke from spreading, these doors give occupants extra time to get out and firefighters extra time to reach the scene. This containment is critical in high-rise buildings, hospitals, and schools where large numbers of people might be present.

2. Property Protection

Fire-rated doors help prevent damage by slowing the spread of fire and smoke. Containment reduces damage to the building structure, which lowers repair costs and losses from fire damage.

3. Compliant With Building Codes

Many local and national building codes dictate where commercial and residential buildings must install fire-rated doors. Adhering to these codes is usually legally required, and insurance companies often require it too. Installing fire-rated doors helps you meet these regulatory requirements and keep your building up to code. If you manage a condo or multifamily property, read our guide to condo fire door compliance in South Florida.

Choosing the Right Fire-Rated Door

1. Decide upon Fire Rating

Fire-rated doors are available in various ratings, ranging from 20 minutes to 3 hours. Your premises’ requirements and where in the building you’re installing the door determine the rating you need. Ask a fire-safety professional or a local building inspector to help you determine the rating you need.

2. Material

Choose hollow metal, steel, or aluminum and glass based on your needs for security, aesthetics, and budget. Each type offers certain advantages, so pick the one that fits your building’s needs.

3. Installation Must Be Proper

Installation plays a big role in how well a fire-rated door performs, so have a professional install and fit it accurately inside the door frame. A poorly installed fire-rated door can lose its fire resistance.

4. Maintenance Routine

Regular maintenance is necessary so that fire-rated doors remain effective. NFPA 80 requires annual inspection and testing of fire door assemblies in most buildings, with documentation kept on site. Periodically inspect doors for damage, wear, or malfunction. Ensure that seals and hardware are functioning correctly, the door closes fully, and the latches are secure. Our Miami-Dade fire door inspection checklist walks through what inspectors look for.

Frequently Asked Questions

How long can a fire-resistant door hold back fire?

Ratings run from 20 minutes up to 3 hours, depending on the door, frame, and hardware assembly. The rating that applies to you depends on where the door sits in the building.

Do fire doors need to be inspected?

Yes. NFPA 80 requires annual inspection and testing of fire door assemblies in most buildings, and records should be kept on site.

Are Apex fire doors certified?

The assemblies we supply are UL listed to UL 10B and UL 10C and meet NFPA 80 requirements. See our technology and certifications page for details.
