Firestop & Passive Fire Protection Services

Large Opening and Multiple Penetration Firestopping Solutions in Qatar

Comprehensive Firestop Systems for Mixed-Use Mechanical & Electrical Penetrations

MANYCON TRADING AND CONTRACTING – Qatar is a trusted leader in large opening firestopping and multiple penetration sealing, approved by Qatar Civil Defense (QCD). We provide UL/FM-tested firestop systems designed for fire-rated walls and floors penetrated by grouped services such as pipes, cables, ducts, and conduits. Our solutions ensure compliance, safety, and integrity in complex building infrastructure. Our firestop professionals handle penetrations in electrical rooms, shaft walls, MEP corridors, and service risers, using certified modular firestop sleeves, pillows, sealants, wraps, and collars to provide a fire barrier system for openings in slab and walls.

What Are Large & Multi-Penetration Firestop Systems?

Large openings or grouped penetrations in fire-rated assemblies require specialized sealing systems to maintain the fire resistance of the barrier. These openings typically house clusters of electrical, mechanical, and communication systems. Without proper firestopping, they act as direct channels for fire, smoke, and toxic gas, compromising the building’s fire safety strategy and evacuation protocol. Our firestop for wall and floor openings ensures passive fire protection for large MEP openings and utility penetrations.

Our Large Opening Firestop Services in Qatar Include:

01. Grouped Cable Tray & Conduit Sealing We apply tested firestop assemblies around cable bunches, trays, and conduits using firestop pillows, intumescent wraps, modular sleeves, and UL-listed firestop for multiple penetrations.
02. Mixed Penetration Firestop (Pipes + Cables + Ducts) Large floor or wall openings with multiple service types are sealed with layered firestop components including fire barrier material for large openings and multi-service penetration firestop systems.
03. Wall & Floor Opening Fire Barriers We construct fire-rated bulkheads and compartment barriers using firestop boards, mineral wool, ablative coatings, and firestop mortar for large voids.
04. Flexible Firestop for Service Upgrades Our modular firestop sleeves and adjustable systems allow for future cable pullouts or MEP service upgrades without breaking the fire barrier.
05. UL/ASTM Tested Systems for High-Traffic Areas Installation of UL 1479 and ASTM E814 compliant firestop systems for data centers, plant rooms, and MEP service shafts. We deliver certified firestop installer for penetrations and conduct firestop inspection for large penetrations.
