Applications
Entry-level fire protection for residential and light commercial applications
30-minute fire doors (FD30/EI30) provide the minimum code-required fire resistance for many applications. They offer essential fire compartmentation while representing the most cost-effective fire door solution.
Rating explanation: A 30-minute rating means the door assembly has been tested to resist fire for at least 30 minutes, providing occupants time to evacuate and limiting fire spread between compartments.
Primary Applications
Residential Apartments
Entrance doors to individual dwelling units from common corridors. Protects occupants and prevents fire spread between units.
Hotel Guest Rooms
Guest room entrance doors from corridors. Provides fire separation while maintaining warm, welcoming appearance.
Office Partitions
Internal doors between office areas where 30-minute compartmentation is specified. Cost-effective fire separation.
Retail Premises
Fire separation doors in retail environments including stockroom access and staff areas.
Educational Facilities
Classroom and administrative area doors where 30-minute separation is acceptable.
Healthcare - Non-Critical
Administrative and support areas in healthcare facilities where lower fire resistance is acceptable.
30-Minute Suitability by Building Type
| Building Type | Suitability | Notes |
|---|---|---|
| Residential (Low-Rise) | Common | Standard for apartment entrance doors, internal doors |
| Residential (High-Rise) | Limited | Higher ratings typically required for corridor doors |
| Hotels (Low-Rise) | Common | Guest room doors in buildings under 4-5 stories |
| Offices | Common | Acceptable for many internal partitions, especially with sprinklers |
| Retail | Common | Small to medium retail premises |
| Healthcare | Limited | Non-patient areas only; patient areas require higher ratings |
| Industrial | Limited | Low-risk areas only; production areas typically require higher |

When to Choose 30-Minute Fire Doors
Code Specifies 30 Minutes
When building code specifies 30-minute rating, there's no benefit to higher ratings.
Budget Optimization
30-minute doors are the most cost-effective fire doors. Where permitted, they maximize value.
Maximum Glazing Required
Largest vision panels and full-lite glass options are available at 30-minute rating.
Lighter Construction
Thinner, lighter doors reduce hardware requirements and are easier to operate.
Widest Aesthetic Choices
All materials, finishes, and configurations available without high-rating limitations.
Sprinklered Building
Sprinkler protection may allow 30-minute doors where non-sprinklered would need higher.
Recommendation: 30-minute fire doors are the optimal choice when code permits, offering the best combination of cost, customization options, and fire protection. Always verify code requirements before specifying—never assume 30-minute is acceptable. When in doubt, consult your fire engineer or building control.

Installation Requirements
Proper installation requirements for half-hour fire door assemblies
Installation Advantage: Lighter Weight
30-minute fire doors offer installation advantages over higher-rated doors:
Critical: Improper installation voids the fire rating. Fire doors must be installed by qualified personnel per NFPA 80 and manufacturer instructions.
Clearance Requirements (NFPA 80)
| Location | Maximum Gap | Note |
|---|---|---|
| Hinge edge | 3mm (1/8") | Measured with door closed |
| Lock edge | 3mm (1/8") | Measured with door closed |
| Top edge (head) | 3mm (1/8") | Measured with door closed |
| Meeting edges (pairs) | 3mm (1/8") | Requires astragal |
| Bottom (no threshold) | 20mm (3/4") | Standard |
| Bottom (with threshold) | 10mm (3/8") | With seal |
Common Installation Mistakes to Avoid
Excessive Clearances
Consequence: Fire rating compromised—fails inspection
Prevention: Measure carefully, adjust frame as needed
Missing Frame Grout
Consequence: Fire can bypass frame—rating voided
Prevention: Always grout or insulate hollow frames
Non-Fire-Rated Hardware
Consequence: Assembly loses certification
Prevention: Use only specified fire-rated hardware
Door Doesn't Latch
Consequence: Fire door provides no protection if not closed
Prevention: Adjust closer force, check strike alignment

Frequently Asked Questions
Common questions about 30-minute fire doors
FD30 doors are typically used for interior corridors in low-rise buildings, office partitions, storage rooms, utility closets, and residential corridors. Check your local building code as requirements vary—stairwells and exit corridors often require higher ratings.
