Top-Hung Escape Roof Windows

In modern architectural design, roof windows not only provide natural light and ventilation but also serve as critical escape routes in emergencies. Top-hung fire escape roof windows, with their unique design and high-performance safety features, have become a preferred solution for commercial buildings, public facilities, and high-end residential projects.

1. Key Features

▶ Emergency Escape Function

Designed for fire and other emergencies, the sash can be quickly opened to a wide angle (typically ≥70°), creating a spacious exit. Some models feature a one-touch release mechanism or removable glass panels for tool-free operation.

▶ Top-Hung Structure Advantages

Safety & Stability: Hinges are positioned at the top, allowing the sash to tilt outward and upward, minimizing collision risks.
Weather Resistance: When closed, the window forms a tight seal with multi-layer waterproof gaskets to prevent rain infiltration.
Ventilation Control: Can be set at a slight tilt for continuous airflow without compromising aesthetics.

▶ High-Strength Materials & Certifications

Tempered or fire-resistant laminated glass, with some models tested to EN 1363-1 standards (30+ minutes fire resistance).
Frames made of thermally broken aluminum or reinforced PVC, meeting BS 6375 wind load requirements.

2. Architectural Adaptability

Custom Sizing: Available in widths (800mm–1500mm) and heights (1000mm–2400mm), suitable for pitched (15°–90°) or flat roofs.

Aesthetic Integration: Minimalist frames with concealed hardware, optional finishes (e.g., matte black, metallic silver) to complement modern facades.

Smart Upgrades: Optional smoke sensor integration for automatic opening or connection to building management systems.

3. Installation & Compliance

▶ Escape Route Planning

Must comply with international codes (e.g., IBC) and local fire safety regulations, ensuring unobstructed access with auxiliary ladders or descent devices.

▶ Professional Installation

Waterproofing with EPDM or torch-applied membranes for leak-proof joints.
Structural reinforcement may be required based on roof load capacity.

4. Recommended Applications

Commercial: Atriums, hotel stairwells.

Public Buildings: Schools, hospitals, sports arenas.

Industrial: Warehouses, factory roof exits.

5. Maintenance & Inspection

Biannual checks are advised:

Clear debris from tracks and lubricate hinges.
Test emergency release mechanisms.
Inspect sealant integrity.

Top-hung escape roof windows seamlessly combine safety and design, making them essential for sustainable architecture. Opt for ISO 9001-certified products and professional installation to maximize building safety.
