FIRE-RATED DOORS: PURPOSE AND INSTALLATION

Fire-rated doors are a key part of any building’s safety system. They help contain fire and smoke, protecting people and property. These doors are installed not only to meet code requirements, but also to provide peace of mind and real protection in emergency situations.

WHY FIRE-RATED DOORS MATTER AND HOW TO INSTALL THEM PROPERLY

The main purpose of a fire-rated door is to contain fire, heat, and smoke within a defined area, slowing down the spread and giving people time to evacuate and emergency crews time to respond. They are commonly installed along evacuation routes, in storage rooms, electrical or mechanical areas, server rooms, underground parking, and between building sections.

Modern fire-rated doors are built from durable steel with fire-resistant insulation and are equipped with certified hardware — heat-resistant locks, closers, intumescent seals, smoke-proof thresholds, and sometimes fire-rated glass. Doors come in different sizes, styles, and fire-resistance levels (typically 20, 45, 60, or 90 minutes), depending on the building’s layout and safety requirements.

Even the best door will fail if it’s not installed correctly. Proper installation involves precise measurements, preparing the opening, anchoring the frame using fire-rated fasteners and sealants, and correctly setting up all hardware components. It also includes checking door alignment, closing speed, and ensuring a tight seal. Wall type, material, usage conditions, and code requirements all play a role in how the door should be mounted. Once installed, each door should be tested to confirm that it closes automatically, seals properly, and functions safely under pressure.

If a fire-rated door becomes misaligned, lets smoke through, or if the hardware is worn out, repairs are essential. Fixing these issues in time helps maintain the fire-resistance rating and prevents compliance violations during inspections.

We provide full-service fire-rated door solutions — from helping you choose the right model to certified installation and ongoing maintenance. Our experts follow current building and fire safety standards, with a focus on precision, durability, and long-term protection.

If your door needs repair, we’ll restore its performance quickly and professionally: replacing worn seals, adjusting closers, aligning the frame, or upgrading hardware.
