Fire Stopping & Compartmentation Integrity

Advanced Glass: Fire Stopping & Compartmentation Integrity

Effective fire stopping is essential to maintaining the integrity of compartmentation lines within the external envelope — but too often, it’s overlooked or fragmented between multiple trades.

At Advanced Glass, we incorporate fire stopping as part of our complete façade package, ensuring it’s correctly installed and fully coordinated with both glazing systems and rainscreen cladding.

Glazing vs Cladding Fire Stops

The fire stopping requirements vary depending on the façade system. Behind curtain walling or window systems, fire stops are typically installed at every compartment line — often slab edges or floor zones — and must be compressible yet retain their performance under movement and thermal load. These systems must interface tightly with mullions and framing to prevent the passage of flame or smoke.

Behind rainscreen cladding, fire stopping is commonly installed horizontally (and in some cases vertically) between the inner wall and outer cladding at compartment lines, using open-state barriers that allow ventilation under normal conditions but expand to seal gaps in the event of fire. These must be installed with continuous contact to both the SFS or wall and cladding support system, with no gaps, sagging, or misalignment.

Integrated Installation, Not Piecemeal Responsibility

By taking responsibility for both the primary façade system and fire stopping, Advanced Glass eliminates grey areas between trades. You don’t have to manage or mediate between glazing and cladding subcontractors arguing over who should fire stop which area — we handle it all. This approach ensures:

  • Continuous compartmentation across the entire elevation
    • Elimination of voids or overlaps due to differing systems or installation methods
    • Fewer coordination issues, particularly around window openings, interfaces, and slab edges
    • Reduced compliance risk at the sign-off stage

Technical Performance

We supply and install tested and certified fire stop systems with performance ratings typically up to:

  • EI60, EI90, and EI120 — providing both integrity (E) and insulation (I)
    • Movement accommodation to meet façade tolerance requirements
    • Smoke sealing (S) performance when required
    • Compliance with EN 1366-4 and relevant sections of Approved Document B

Quality Assurance & Documentation

All fire stopping works are carried out by trained installers and subject to a full Quality Assurance (QA) process, including:

  • Pre-installation inspection and coordination with SFS, cladding, and glazing elements
    • In-situ documentation including location-specific photographic evidence
    • Sign-off sheets with fire stop type, EI rating, and batch reference
    • Final QA pack issued to the client, main contractor, and building control

This level of transparency ensures a clear audit trail, simplifies third-party review, and provides confidence that compartmentation has been preserved throughout the building envelope.

Frequently Asked Questions

Aluminium windows offer durability, low maintenance, excellent thermal efficiency, and modern aesthetics, making them ideal for commercial applications.

Yes, modern aluminium windows feature thermal break technology to improve insulation, achieving low U-values meeting Part L building regulations and often exceeding it.

Options include double or triple glazing, solar control glass, acoustic glass, laminated safety glass, and enhanced security glass, depending on performance needs.

Yes, commercial aluminium windows can be PAS 24 certified and meet Secured by Design standards with multi-point locking systems with reinforced frames.

When properly maintained, aluminium windows can last 30 – 40 years, due to their corrosion resistance and high-quality powder-coated finishes.

Yes, they are available in a wide range of RAL colours, anodised finishes, and different configurations, including casement, tilt-and-turn, and sliding options.

Aluminium windows are designed to withstand extreme weather conditions, with high wind load resistance and water-tightness ratings to ensure long-term performance.

Minimal maintenance is needed – just the occasional cleaning and lubrication of moving parts is required to help ensure smooth operation and longevity.

Yes, aluminium is up to 100% recyclable, and many modern aluminium window systems use recycled materials, supporting sustainable building practices.

Lead times vary depending on customisation and project size, but standard windows typically take 12 – 16 weeks for design, manufacturing and delivery.
