If you're going to buy durable steel thermal insulating fire resistant window made in China, welcome to get free sample from our factory. All customized products are with high quality and low price.
In modern construction, safety is never a compromise. Yet, protecting lives and property from fire should not come at the cost of natural light, thermal comfort, or visual harmony. Our Steel Insulated Fire-Resistant Windows are engineered to solve this very dilemma - offering a perfect balance of high-performance fire protection, thermal insulation, acoustic comfort, and aesthetic flexibility.


Superior Manufacturing Process for Lasting Durability
Every frame undergoes a meticulous phosphating and rust-removal process before coating. This chemical treatment not only eliminates microscopic rust but also creates an ideal surface for coating adhesion. Following this, the frame is finished with electrostatic spraying - a technique that ensures uniform, chip-resistant, and corrosion-proof coating. This dual-process results in a window that stands firm in high-humidity, coastal, or industrial environments, significantly extending service life while reducing maintenance costs.
Exceptional Fire Resistance & Thermal Insulation – Dual Protection
Our windows are built to actively resist fire while limiting heat transfer. Classified as Class A (highest) and Class B fire-resistant levels, they are independently tested to withstand high temperatures and prevent flame spread for up to 1.5 hours or more, depending on configuration. The secret lies in the combination of steel frames and specially selected fire-resistant glass:
Composite fire-resistant glass – multi-layer construction with intumescent interlayers that expand under heat, forming an opaque insulating barrier.
Monolithic fire-resistant glass – clear, single-pane solution with inherent fire resistance for applications requiring high transparency.
Both options dramatically reduce heat radiation and conduction, keeping the non-fire side cooler and buy precious evacuation time.
Moreover, the steel frame combined with thermal break technology improves overall energy efficiency - reducing heat loss in winter and solar heat gain in summer. This translates into lower HVAC operational costs and increased occupant comfort.


Acoustic Comfort Without Compromise
Steel's inherent density, when paired with multi-pane fire-resistant glass, creates a highly effective sound barrier. Whether your building is near an airport, highway, or industrial zone, our windows significantly reduce noise intrusion, creating a quieter and more productive interior environment.
Elegant Appearance & Customizable Finishes
Gone are the days of clunky, industrial-looking fire windows. Our products feature clean lines, consistent profiles, and electrostatic coating that delivers a smooth, lustrous finish - available in a wide range of RAL colors or custom shades. The coating also resists UV fading and chalking, ensuring a premium appearance for decades. This makes our windows suitable for high-end residential projects, hotels, commercial atriums, and institutional buildings where aesthetics matter as much as safety.

Flexible Configurations for Any Architectural Design
We understand that every building is unique. That's why we offer custom design options:
Fixed Fire Window – ideal for curtain walls, stairwells, and corridors requiring unobstructed views and maximum light transmission.
Casement Fire Window (Top, Side, or Bottom-hung) – operable for ventilation and smoke exhaust, with fire-rated hardware that automatically closes in case of fire.
We also support non-standard dimensions, special shapes, and dual-action opening mechanisms. Additionally, you can choose between composite fire-resistant glass (better insulation) or monolithic fire-resistant glass (higher clarity and lighter weight) based on your project's specific fire-rating requirements (Class A or B).
