• NBCS 2026
National Building Construction Standards 2026, Part F
NBCS 2026 (SP 7:2026) replaced NBC 2016 in April 2026. The following clauses are quoted directly from the published standard.
Part F, Clause 2.22, Note 2
On mandatory exit protection
“Fire doors in exits should have fire rating as required in this Part to meet the requirement of integrity and stability; and the minimum insulation criteria should be 30 min.”
Part F, Clause 2.24
On firefighting shafts
“An enclosed shaft having a protected area of 120 min fire resistance rating comprising a protected lobby, staircase, and fireman's lift... The firefighting shaft should be equipped with 120 min fire doors.”
Part F, Clause 3.5.4.6
On vertical openings and compartmentation
“Every vertical opening between the floors of a building should be suitably enclosed or protected, as necessary, to provide reasonable safety to the occupants... and limitation of damage to the building and its contents.”
Minimum ratings by location, NBCS 2026
| Location / Requirement | Minimum Rating | NBCS 2026 Clause |
|---|---|---|
| Single-staircase building - lobby / stairwell | 120 min (lobby) / 60 min (stairwell) | Cl. 1.2, Note 2 |
| Firefighting shaft (lobby, staircase, fireman's lift) | 120 min | Cl. 2.24 |
| Non-naturally ventilated (pressurised) areas - lift lobby & stairwell entrances | 120 min | Cl. 4.2.7 |
| Basement access from occupied floors above (car parking) | 120 min | Cl. 4.2.19.4 |
| Lift lobby at all levels, pressurised 25–30 Pa | 120 min | Table 5, Cl. 4.4.2.5(b) |
| Horizontal exit doorway between compartments | 120 min | Cl. 2.40, Annex D-4.1 |
| Guest room corridors / sleeping accommodation exit corridors | 30 min (door) / 60 min (wall) | Cl. 4.5.3.3 |
| Fire separating walls (industrial, non-hazardous zones) | 120 min | Cl. 6.7.1.1 |
| Openings within 3 m of a fire separating wall | 60 min | Cl. 6.7.1.1(g) |
| Type 4 construction - fire separating walls/floors | 120 min | Cl. 3.5.4.3 |

Fire curtain performance types, NBCS 2026 + EN standards
NBCS 2026, Clause 4.5.2.1, sets out three fire curtain performance types directly, requiring third-party certification for each. BÖLDT curtains meet these parameters and additionally carry EN certification for international specifiers.
Integrity
Resists flame and hot gas passage, 120 min
Radiation control
Heat transfer capped at 15 kW/m² at 1 m
Insulation
Limits far-face temperature rise, +140°C max
Smoke control
Leakage capped at 3 m³/m/h at 25 Pa
EN 1634-1
Fire Resistance of Door and Shutter Assemblies
Governs fire resistance testing of door sets, shutter assemblies and openable windows - including fire curtain systems. Curtains are evaluated on their ability to maintain integrity and control fire and smoke spread across openings for defined periods.
EN 12101-1
Smoke and Heat Control Systems
Defines performance requirements for smoke and heat control systems in buildings. Curtains tested to EN 12101-1 demonstrate measurable performance in real fire scenarios, supporting life safety strategy and regulatory compliance.
EN 15269-11
Extended Application of Fire Resistance Test Results - Curtain Assemblies
Provides the framework for extending fire test results across a defined range of curtain sizes, widths and installation conditions, rather than requiring independent testing for every configuration.
EN 13501
Fire Classification of Construction Products
Translates fire test results into clearly defined performance ratings - integrity (E), radiation (W) and insulation (I) - giving specifiers, consultants and authorities a transparent, universally understood classification.
Curtain type restrictions by building occupancy, Table 6, NBCS 2026 (Cl. 4.5.3)
| Building Type | Restriction |
|---|---|
| Enclosed basement vehicle parking | Type 2 only, limited to driveways ≤ 9 m |
| Hospitals / nursing homes (with beds/sleeping patients) | Type 3 only |
| Buildings for custody/care of children, aged, incapable persons | Type 3 only |
| Mercantile buildings / department stores / markets | Type 2 only |
| Assembly buildings (with/without atriums) | Type 2 only |
| Business occupancy buildings | Type 1 only |
| Datacentre buildings | Type C only (fire-rated glazed partition/door, not fabric) |
| Hotel buildings (with or without dining facilities) | Type C only (fire-rated glazed partition/door, not fabric) |
