DarQ’s Fire Door Boards are engineered to meet strict fire safety standards and form a critical component in modern fire protection systems. Designed for use in the core of certified fire doors, these boards offer unmatched thermal resistance, strength, and compatibility with intumescent sealing systems.

Key Features

High Fire Resistance
Withstands high temperatures for 30 to 240 minutes, depending on door specification—helping to contain fire and smoke within designated zones and ensuring safe evacuation.

Robust Construction
Manufactured from fire-grade core materials such as magnesium sulfate board, reinforced with fiberglass and non-combustible fillers. Offers exceptional dimensional stability under thermal stress.

Integrated Sealing Support
Compatible with intumescent seals that expand when exposed to heat, forming a smoke and flame barrier around door perimeters. Optional integration with fire-rated glazing available.

Certified & Compliant
Meets global fire door testing standards such as UL, BS 476, EN 1634-1, and IS norms (India-specific). Tailored to your regional compliance needs.

Lightweight & Easy to Process
Despite its performance, the board remains lightweight and easy to cut, drill, and machine—ideal for efficient door manufacturing and installation workflows.
