Our certifications
Fire windows ( fire-resistant windows) are specially designed glazing systems that resist the spread of fire and, depending on the classification, limit heat transfer or radiant heat for a specified period. Unlike standard windows, they use tested fire-resistant glazing within compatible frames, seals, beads and fixing systems (often steel or timber with intumescent seals) to maintain integrity for a specified duration—typically 30, 60, or 120 minutes. Their purpose is to compartmentalize fires, protecting escape routes and critical building areas while complying with UK fire safety regulations.
For projects in Bradford, fire windows are often specified for dense sites where buildings sit close together, internal layouts change frequently, and escape routes must remain protected without losing daylight. The correct system should be chosen as a complete glazed assembly, not as glass alone, because the pane, frame, seals, beads, fixings, and surrounding construction all determine the final fire performance.
For Bradford projects, this also means checking how the glazing connects with adjoining walls, doors and partitions. A fire-rated pane cannot compensate for an unsuitable frame or poorly prepared opening, so the full glazed system should be considered before procurement, fabrication or installation begins.
Why Are Fire Windows Important in Bradford
Bradford has a mix of residential, commercial, historic and industrial buildings where fire-resistant glazing may form part of the required compartmentation or protected escape strategy. Fire safety requirements are primarily established through the Building Regulations and Approved Document B, together with the Regulatory Reform (Fire Safety) Order 2005 for premises within its scope. The Fire Safety Act 2021 and Fire Safety (England) Regulations 2022 introduced additional duties for relevant multi-occupied residential buildings. After tragedies like Grenfell Tower, the Building Safety Act 2022 and Regulatory Reform (Fire Safety) Order 2005 have tightened requirements for passive fire protection. Fire windows help:
– Protect escape routes (e.g., corridors, stairwells).
– Limit fire spread in residential flats, offices, and public buildings.
– Meet insurance and regulatory demands, reducing liability risks.
Why Buildings in Bradford May Need Fire Windows
Beyond compliance, fire windows offer:
Life Safety: Buy time for evacuation and firefighter access.
Property Protection: Minimize structural damage and business disruption.
Legal Compliance: Supports compliance with Building Regulations, the building’s fire strategy and any relevant fire safety standards.
Project Requirements: Fire-resistant glazing can help satisfy fire strategy, client and insurer requirements where specified.
Aesthetic Flexibility: Modern designs blend seamlessly with architectural styles.
When planning a replacement or new installation, the first step is to confirm the required fire rating, window position, wall type, and whether the glazing protects an escape route, compartment wall, stair core, façade, or internal screen. These details guide the choice between E, EI, and EW performance and help avoid ordering a system that looks suitable but does not match the fire strategy.
Early coordination is especially useful in Bradford refurbishments, where the available opening, wall construction, access restrictions and design requirements may all affect the final system. Confirming these details before manufacture helps reduce site delays and avoids last-minute changes that can compromise the tested specification.
How Fire Windows Are Rated in Bradford?
Fire-resistant glazing is tested using the standard appropriate to the type of assembly. BS EN 1364-1 applies to glazed non-loadbearing wall systems, while BS EN 1634-1 covers openable windows. Fire-resistance performance is classified under BS EN 13501-2:
1. E Fire Windows (Integrity Only)
Measures how long the window prevents flames and hot gases from penetrating (e.g., E30 = 30 minutes).
Use Case: Suitable where heat insulation isn’t critical (e.g., non-escape route partitions).
2. EI Fire Windows (Integrity + Insulation)
Combines integrity with insulation by limiting the transfer of excessive heat to the unexposed side. EI-rated glazing may be required where both integrity and insulation form part of the fire strategy.
Such as:
EI30: 30 minutes of integrity and insulation performance.
EI60: 60 minutes of integrity and insulation performance.
EI90/EI120: 90 or 120 minutes of integrity and insulation performance where required by the project specification.
3. EW Fire Windows (Radiation Control)
Definition: Blocks flames and reduces radiant heat transfer (but doesn’t fully insulate).
Example: EW30 provides 30 minutes of integrity together with limitation of radiant heat. Its suitability depends on the location of the glazing and the project fire strategy.
Why Do fire Windows Ratings Matter?
Escape Routes: Where glazing forms part of a protected escape route, the required integrity and insulation performance should follow the building’s fire strategy.
Compartmentation: Fire-resistant glazing can maintain the required fire separation while allowing visibility and daylight.
Architectural Needs: E, EI or EW performance can be selected where permitted by the fire strategy and tested system.
For example, different glazed elements within a Bradford office building may require different fire-resistance classifications depending on whether they protect a stair, compartment boundary or internal circulation space. The required rating should follow the project fire strategy.
During specification, it is also important to consider how close occupants may be to the glazing during evacuation. A protected corridor, stair lobby or escape route often needs a different level of performance than a screen used mainly for separation, visibility or daylight.

Where Are Fire Windows Typically Used?
Fire windows are critical in buildings where compartmentation and escape route protection are required:
– Stairwells & Fire Escapes: Fire-resistant glazing may be required where it forms part of the fire-resisting construction protecting an escape route. The required rating should follow the fire strategy.
– Commercial Buildings: Offices, hospitals and schools may use fire-resistant glazing in corridors, atriums and partitions where required by the building design and fire strategy.
– Residential Blocks: Fire-resistant glazing may be required where glazed openings form part of separating or fire-resisting construction.
– Industrial Sites: Fire-resistant glazing can be used between fire compartments where visibility is required alongside the specified level of fire resistance.
– Heritage Buildings: Appropriate fire-resistant glazing systems can help improve fire performance while respecting existing architectural character, subject to the required approvals and tested specification.
Fire windows in Bradford are also useful in mixed-use buildings where residential, retail, office, and service spaces meet within one structure. They help separate higher-risk areas such as plant rooms, commercial kitchens, bin stores, basement corridors, and service risers while keeping visibility and natural light between spaces. This is particularly valuable where solid fire-resistant walls would make circulation routes feel closed or difficult to supervise.
Compliance with UK Fire Safety Regulations
Fire-resistant glazing should be specified in accordance with the applicable Building Regulations, project fire strategy and relevant test and classification standards, including:
– BS EN 13501-2: Classifies fire performance (E, EI, EW ratings).
– Building Regulations Approved Document B: Provides guidance on fire-resisting construction, including limitations and requirements for glazed elements in relevant locations.
– Regulatory Reform (Fire Safety) Order 2005: Requires responsible persons to assess and manage fire risks in premises within its scope and maintain relevant fire precautions.
– Local Authority Approvals: Bradford projects may require Building Regulations approval through Bradford Council Building Control or an appropriate registered building control approver, depending on the work.
For responsible persons, compliance also depends on keeping information accessible after installation. Product certificates, rating details, drawings, inspection notes and maintenance records help future fire risk assessments, refurbishment works and management reviews stay connected to the original fire window specification.
Materials and Design Options Available
Modern fire windows balance safety with aesthetics:
Window Glass Types
– Wired Glass: A traditional fire-resistant glazing option used within compatible tested systems.
– Ceramic Glass: A specialist fire-resistant glazing material used in certain tested systems.
– Laminated Fire Glass: Multi-layer fire-resistant glazing available in different tested performance classifications.
Frame Materials
– Steel: robust, slim-profile framing for compatible fire-resistant glazing systems.
– Timber: Can provide a traditional appearance where a compatible tested fire-resistant glazing system is available.
– Aluminium: Provides modern profiles and a range of powder-coated finishes within tested fire-resistant systems.
Window Design Flexibility: Frame colours, glazing configurations and additional acoustic, thermal or security performance may be available where supported by the tested system.
Made-to-measure fire windows are important in Bradford refurbishments because many properties have older openings, uneven reveals, listed-building constraints, or non-standard partition layouts. Custom sizing allows the glazing system to fit cleanly into the available aperture, align with surrounding doors or partitions, and maintain the tested clearances around the frame. This reduces site alterations and supports a more reliable finished installation.
The visual specification should be matched to the building as carefully as the rating. Steel frames provide a slim, robust profile for commercial, heritage, and high-use areas. Aluminium frames offer a clean modern look with powder-coated colours that match façades, internal screens, or door systems. Timber-framed solutions suit residential and traditional interiors where a warmer finish is needed.
The chosen frame material should match the building conditions as well as the visual design. High-use commercial areas need impact resistance and easy cleaning, while heritage or residential interiors may need slimmer profiles, careful fixing details or warmer finishes.

Frequently Asked Questions
What is a fire window, and how does it work?
Fire windows are tested fire-resistant glazing systems designed to maintain specified fire performance for a defined period. Depending on the classification, they may provide integrity (E), integrity and radiation control (EW), or integrity and insulation (EI). The glass, frame, seals, beads, fixings and surrounding construction work together as part of the complete system. They use tempered or ceramic glass and intumescent seals that expand under heat, sealing gaps to prevent fire spread. Unlike standard windows, they’re tested to BS EN 1364-1 for compliance.
Are fire windows required by law in Bradford buildings?
Not every window in every Bradford building needs to be fire resistant. Fire-resistant glazing may be required where an opening forms part of fire-resisting construction, such as certain compartment boundaries or protected escape routes. The exact requirement depends on the building design, location of the glazing, Building Regulations and project fire strategy.
What fire rating should my windows have?
EI30: Minimum for residential corridors (30-minute resistance).
EI60: Standard for commercial stairwells/high-rises.
EI90/EI120: Industrial or critical infrastructure.
Tip: Your architect or fire risk assessor will specify based on building use.
Can fire windows look the same as regular windows?
Modern fire glazing is nearly indistinguishable from standard windows. Options include slim-profile glass, timber or aluminium frames, and even tinted or decorative designs—balancing safety with aesthetics.
How are fire windows tested and certified in the UK?
The applicable test standard depends on the construction. BS EN 1364-1 applies to glazed non-loadbearing wall systems, while BS EN 1634-1 covers openable windows. Fire-resistance performance is classified under BS EN 13501-2. Test and classification evidence should relate to the complete glazing system and intended application.
Where are fire resistant windows typically installed?
Protected stairways and escape routes where fire-resistant glazing is required by the fire strategy.
Corridors in flats/offices.
Compartment walls between flats or commercial units.
Facades (if part of a fire compartment).
What’s the difference between integrity and insulation in fire windows?
E (Integrity): Resists fire penetration for the stated period.
EI (Integrity + Insulation): Provides integrity while also limiting excessive heat transfer.
EW: Provides integrity while limiting radiant heat transfer.
Can I replace my existing windows with fire-rated ones?
Yes, but retrofitting requires:
Structural assessment (weight/frame compatibility).
Competent installers familiar with the tested glazing system, its framing, seals, fixings and installation requirements.
How much do fire windows cost in Bradford?
Prices vary by size, rating, and material:
EI30: £300–£600 per m².
EI60+: £500–£1,200 per m².
