Non-Insulated Fire-Resistant Windows (usually classified as Class C fire-resistant windows in national standards) are an important component of passive fire protection systems in buildings. Unlike Class A insulated fire-resistant windows, their core performance indicator only requires meeting fire integrity requirements, meaning that the glass and window frame must not crack, detach, or allow fire to pass through within a specified fire duration, but there are no mandatory restrictions on the temperature rise of the unexposed side.
Aluminum alloy models emphasize lightweight design and aesthetic compatibility, perfectly solving the problems of monotonous appearance and damage to building facades associated with fire-resistant windows. The profiles undergo weather-resistant processing, making them UV-resistant and weather-resistant, and they are not prone to fading, peeling, or deformation with long-term outdoor use, maintaining an appearance consistent with ordinary commercial doors and windows. Most overseas office buildings, street-front commercial buildings, and ancillary buildings in residential communities prioritize this material, ensuring both fire safety compliance and a unified and aesthetically pleasing overall building facade.
Common Materials
Steel
The most commonly used material, with galvanized/cold-rolled steel frames + single-pane cesium potassium fire-resistant glass or insulated fire-resistant glass. It has good weather resistance and is suitable for exterior walls.
Aluminum Alloy
Thermally broken aluminum alloy frame (main profile ≥ 1.8 mm) + single-pane/double-glazed fireproof glass, balancing energy saving and facade aesthetics, requiring fire-resistant structural treatment.
Key Processes and Our Quality
Profile Substrate: Mainly steel profiles (wall thickness ≥ 1.2 mm cold-rolled steel plate) or new thermally broken aluminum alloy fireproof profiles. The inner cavity must be filled with flame-retardant core materials such as Class A aluminum silicate fireproof cotton to prevent high-temperature deformation and leakage.
Multi-layer Sealing System: High-quality non-insulated fireproof windows require four layers of fire-retardant sealing: fire-expanding sealing strips between the glass and window sash, stepped double seals at the sash-frame overlap, fireproof rock wool/flame-retardant expanding foam sealing at the window frame and wall openings, and reinforcing seals at hardware openings.
Installation and Acceptance: During installation, a spirit level must be used for leveling. Cement mortar must be poured between the steel window frame and the wall and cured for at least 24 hours. Gaps around the glass must be filled with fireproof cotton and sealed with fireproof sealant.
Glass Curtain Wall Unit: Monolithic fire-resistant glass + steel/aluminum fire-resistant frame, used for fire-resistant partitioning of curtain walls.
Installation and Certification: Requires fire protection product certification + type test report; nameplate must indicate C1.50/C1.00/C0.50; steel/aluminum frames are fixed with fire-resistant expansion bolts, seams filled with fire-resistant rock wool + fire-resistant sealant; ordinary expanding foam is prohibited; movable types must be tested for automatic closing.
Its applicable scenarios are very precise, basically covering most low-to-medium risk fire zones worldwide. High-specification insulated fire-resistant windows are not required in scenarios such as warehouses, industrial workshop exterior walls, stairwell skylights, enclosed windows in pipe shafts, equipment rooms, and building ancillary rooms. Choosing Non-Insulated Fire-Resistant Windows can 100% meet local fire regulations while reasonably controlling project budgets and avoiding cost waste caused by excessive performance, making it an excellent choice for cost reduction and efficiency improvement in overseas projects.
In summary, the Non-Insulated Fire-Resistant Window is a highly adaptable basic fire protection product. It eliminates unnecessary insulation structures, focusing solely on solidifying core fire and smoke isolation performance. It is structurally stable, durable, and versatile, suitable for a wide range of applications. For overseas contractors and purchasers seeking compliance, stable quality, and cost control, this window type is a highly cost-effective and essential product for fire compartmentation projects in ordinary buildings.
