Certified Fischer FireStop Systems in Pakistan | Passive Fire Protection

Protect your building, preserve structural integrity, and prevent the spread of fire, smoke, and toxic gases with certified Fischer FireStop systems in Pakistan, supplied by H.S. Ahmed Ally.

When fire breaks out in a commercial high-rise, industrial plant, or hospital, utility penetrations—such as electrical cables, plastic and metallic pipes, HVAC air ducts, and expansion joints—act as open highways for smoke and flames. Fischer passive fire protection systems seal these critical service openings, restoring the fire-resistance rating of walls and floors to give occupants precious time to evacuate.

Whether you are an MEP contractor in Karachi, a site consultant in Lahore, or a project developer in Islamabad, we provide complete, code-compliant fischer FireStop solutions tailored to your exact bill of quantities (BOQ).

Complete Fischer FireStop Product Portfolio

Every building service penetration requires a specific fire-stopping material depending on the substrate (concrete, masonry, or drywall) and the penetrating material (combustible plastic pipes, non-combustible steel runs, or cable trays).

1. Intumescent Sealants and Acrylics (fischer FiAM & FiA)

Intumescent sealants expand rapidly when exposed to temperatures above $180^\circ\text{C}$, forming a dense, carbonaceous char that seals gaps left behind by melting plastic pipes or cable insulation.

  • Fischer FiAM Intumescent Acoustic Mastic: A water-based acrylic sealant engineered for sealing structural joints and small service penetrations in concrete and drywalls.

  • Key Benefit: Provides up to 5 hours of fire resistance while maintaining sound reduction and thermal insulation properties.

2. FireStop Collars  (Fischer FFC)

When plastic pipes (PVC, CPVC, PPR, HDPE) burn during a fire, they melt away, leaving large open holes through fire-rated walls and floor slabs.

  • Fischer FFC Firestop Collar: Stainless steel collars lined with high-expansion intumescent material. Upon heating, the inner liner crushes the softening plastic pipe, completely pinching off the hole.

3. High-Density Mineral Wool Boards & Coatings (fischer FCPS)

For large utility openings where multiple MEP services (cables, cable trays, steel pipes, and ductwork) pass through the same wall or floor slab.

  • Fischer Coated Panel System (FCPS): Pre-coated mineral wool boards treated with fischer Ablative Coating (FBP). Cuts easily to fit complex opening geometries without sacrificing structural fire barrier performance.

4. FireStop Foams, Mortars, and Silicones

  • fischer FF199 PU Foam: A premium 1-component fire-rated polyurethane foam used for filling linear joints and frame voids.

  • Fischer FireStop Silicones (FiS): Flexible, weather-resistant elastomeric sealants designed for external facade joints and wet environments requiring movement capability.

Global Compliance & Local Building Standards

Passive fire protection is heavily regulated across Pakistan. Using uncertified sealants or ordinary expanding foam on utility penetrations can lead to failed civil defense inspections and compromised building safety.

  • UL Listed & ETA Certified: Manufactured under strict European (EN 1366, ETA) and American (UL 1479, ASTM E814) testing standards.

  • Third-Party Approved: Tested for fire resistance, smoke tightness, acoustic performance, and thermal movement.

  • Pakistan Civil Defence Compliant: Aligns with local municipal bylaws and national building codes across Karachi, Lahore, Rawalpindi, and Islamabad.
