Intumescent Fire Seal Strips & Fire Door Seals
DARQ’s Intumescent Fire Seals are engineered to protect lives and property by preventing the spread of fire, smoke, and toxic gases. Designed to expand when exposed to heat, these strips create a strong insulating barrier that seals gaps in fire-rated walls, doors, and glazing systems.
What is an Intumescent Fire Seal?
Intumescent fire seals are specialized components installed around the perimeter of fire-rated doors, windows, and construction joints. Upon exposure to elevated temperatures (typically around 200°C / 392°F), the material reacts and expands, filling voids and stopping the spread of flame, smoke, and heat.
Key Features & Benefits

Effective Smoke & Fire Containment
Provides critical sealing to contain flames, smoke, and hot gases.
Thermal Insulation Barrier
Helps delay heat transfer, protecting adjacent zones from temperature rise.
Code-Compliant Fire Safety
Supports adherence to building codes and fire safety standards.
Versatile Application
Ideal for fire-rated doors, glass partitions, wall joints, and window systems.
Durable & Maintenance-Free
Once installed, requires no power supply or maintenance over time.
