Moisture-proof Swing Fire Window

Updated: 2026-07-21

Overview

Moisture-proof side-hung fire-resistant windows are engineered to provide dual protection against fire and moisture. These windows are typically installed in environments where both fire hazards and high humidity are concerns, such as industrial facilities, commercial kitchens, and coastal buildings. The side-hung design allows for easy operation while maintaining a tight seal when closed. Constructed with fire-resistant glass and frames coated with moisture-proof materials, these windows meet stringent safety standards. They are designed to withstand high temperatures and prevent the spread of flames while also resisting corrosion and water damage, making them a versatile solution for modern construction needs.

Structure and Working Principle

The window consists of a robust frame, usually made of steel or aluminum, coated with a moisture-resistant layer to prevent rust and degradation. The fire-resistant glass is often multi-layered, with intumescent interlayers that expand under heat to block flames and smoke. The side-hung mechanism allows the window to swing open horizontally, providing ventilation when needed. When exposed to fire, the glass and frame work together to maintain structural integrity, delaying the spread of fire and smoke. The moisture-proof coating ensures that the window remains functional in damp environments, preventing warping or seal failure over time.

Key Features

These windows are distinguished by their fire-resistant properties, typically rated for 60-120 minutes of fire protection. The moisture-proof coating adds an extra layer of durability, making them suitable for humid or coastal areas. The side-hung design offers ease of use and maintenance, with options for manual or automated operation. Additional features may include thermal insulation, soundproofing, and customizable sizes to fit various architectural requirements. The combination of fire resistance and moisture protection makes these windows a reliable choice for safety-conscious projects.

Application Areas

Moisture-proof side-hung fire-resistant windows are widely used in commercial kitchens, industrial plants, hospitals, and schools where fire safety and moisture control are critical. They are also popular in coastal buildings or areas with high humidity to prevent structural damage. These windows are often specified in building codes for fire compartments and emergency exits, ensuring compliance with safety regulations. Their versatility makes them suitable for both new constructions and retrofitting projects.

Maintenance and Precautions

Regular maintenance is essential to ensure the window's performance. Inspect the seals and frame for signs of wear or corrosion, and clean the glass and mechanisms periodically to prevent debris buildup. Lubricate hinges and moving parts to ensure smooth operation. Avoid using harsh chemicals that could damage the moisture-proof coating. In case of fire exposure, replace the window if the integrity of the glass or frame is compromised. Always follow manufacturer guidelines for installation and maintenance to maximize lifespan and safety.

B2B Procurement Guide

When procuring moisture-proof side-hung fire-resistant windows, verify the fire rating and moisture resistance specifications to meet project requirements. Request certifications such as ISO or local fire safety standards to ensure compliance. Compare suppliers based on material quality, customization options, and after-sales support. Bulk orders may qualify for discounts, but ensure lead times align with project schedules. Consider logistics and installation services offered by suppliers to streamline the procurement process.
