FD90 Fire Doors

Description
Our FD90 Fire Door is an advanced passive fire protection solution engineered for environments where standard 30 or 60-minute doors are insufficient. Constructed with a specialized 64mm thick high-density mineral or multi-layer core, it provides a robust barrier against extreme heat and flames for a minimum of 90 minutes. This door is specifically designed for high-risk areas such as plant rooms, lift shafts, and large commercial server rooms. When configured as an FD90S, the assembly includes advanced smoke seals to mitigate the spread of toxic gases, ensuring maximum safety for the building’s occupants and structural integrity during a significant fire event.

Key Features
90-Minute Integrity: Rigorously tested to withstand furnace temperatures for an hour and a half.
Reinforced 64mm Profile: Increased leaf thickness ensures superior stability and prevents warping under intense thermal pressure.
High-Risk Suitability: Specifically designed for “Area of High Fire Risk” compartmentalization as per Building Regulations.
Acoustic Performance: The dense core construction naturally provides high decibel (dB) reduction, ideal for noisy plant rooms.
Heavy-Duty Hardware: Compatible with Grade 13 or 14 ironmongery to support the significant weight of the door leaf.
Versatile Orientation: Tested for both internal and external (with appropriate weather protection) applications.
