The flame-retardant door bottom seal is a multifunctional window and door sealing accessory that combines dustproof and airtight sealing, wind and sound insulation, impact buffering, and flame retardancy and fire resistance, specifically designed for applications with stringent fire safety requirements.
Product Introduction
The flame-retardant door bottom seal is a multifunctional window and door sealing accessory that combines dustproof and airtight sealing, wind and sound insulation, impact cushioning, and flame retardancy and fire resistance. It is specifically designed for applications with stringent fire safety requirements. The product is manufactured using flame-retardant-grade elastomeric rubber, flame-retardant EPDM, or environmentally friendly flame-retardant composite materials, processed through specialized techniques. While maintaining excellent flexibility and sealing performance, it also delivers outstanding flame-retardant properties and complies with relevant fire safety standards.
It is primarily installed at the bottom gap of the door, leveraging its inherent elasticity to form a tight seal against the floor, effectively blocking gaps beneath the door and preventing dust, mosquitoes, insects, wind, and sand from entering the room, thereby reducing the burden of daily cleaning. At the same time, it inhibits convective heat exchange between indoor and outdoor air, enhancing the space’s thermal insulation and reducing air-conditioning energy consumption. When the door is closed, it also provides cushioning and shock absorption, minimizing impact noise from the door leaf and improving the quietness and comfort of both residential and office environments.
Its salient features include flame retardancy and self-extinguishing properties, low smoke emission, and non-toxicity. When exposed to an open flame, it does not sustain combustion easily and will rapidly self-extinguish once the ignition source is removed, effectively slowing the spread of flames and dense smoke. This provides additional time for evacuation and emergency rescue operations in the event of a fire, thereby meeting the safety code requirements for residential buildings, commercial structures, public facilities, computer rooms, fire escape routes, and other such spaces.
The product exhibits excellent resistance to high and low temperatures, aging, and abrasion, remaining resilient over long-term use without hardening, cracking, or deformation. It is easy to install and can be freely cut to match the width of the door, making it suitable for a wide range of door types, including fire-rated doors, entry doors, office doors, hotel guest-room doors, and passage doors. By providing both everyday sealing and protection and meeting stringent fire-safety requirements, it is the ideal choice for modern building door-and-window systems and for enhancing overall safety.
