FIRESTOP

Every year, in industrial, commercial or residential buildings, fires cause a lot of damage and can have serious consequences: victims linked to smoke emissions, toxic gases or flames, material damage, loss of business, water damage linked to extinguishing systems, etc. Unpredictable, uncontrollable in their progression and of varied origin, fires often find their "fuel" and their source of energy in the construction materials (insulation, cables, coatings, etc.) used in buildings, the stored materials (wood, textiles, paints, solvents, chemical products, etc.), the configuration of the premises, etc.

Fire risk prevention, with the evacuation of people and the preservation of the building as a priority, is therefore a key factor that architects, design offices, companies, etc. must take into account when designing, building, or renovating a building. To facilitate and secure the evacuation of people, but also to prevent the spread of fire, smoke, and toxic gases, the increasingly strict legislation in force sets fire safety standards. It imposes various preventive and active measures, depending on the use of the buildings: staff training, emergency plans, non-flammable coatings, fire walls, compartmentalization of spaces, fire extinguishers, sprinklers, alarms, smoke ventilation systems, fire detectors, etc.

In terms of passive safety, fischer has developed a new range of fire protection products: FIRESTOP. This comprehensive range aims to limit the spread of fire through walls, floors, or ductwork. It includes fire-resistant sealing and waterproofing solutions such as intumescent sealants, silicones, elastomer coatings, polyurethane foams, collars, mortars, and more.

FIRESTOP: a fire-resistant range that complies with European and international standards

Among the various devices that aim to limit the spread of a fire, there is the compartmentalization of the building into different zones by walls, partitions or fire-resistant slabs. To guarantee the fire classification, governed by the NF EN 13501 and NF EN 1366 standards, of walls, floors, partitions and pipes, all singular points such as joints, cable and duct passages, pipes must be treated with suitable products. To perfectly meet market expectations, fischer has designed the FIRESTOP range. The result of many years of experience in the construction field, and enriched by field feedback from project owners, engineers, design offices, etc., the range offers approved products for construction joints and for passage sealing. They have been tested according to European and international standards, and all have an ETA (European Technical Approval).

FIRESTOP: A complete range

Suitable for all materials, concrete, cellular concrete, masonry, plasterboard, etc., fischer quality FIRESTOP products are suitable for both design and building renovation.

FiAM intumescent acrylic sealant:

Compatible with a wide range of materials - wood, steel, concrete, drywall and solid masonry - fischer FiAM sealant is approved for creating construction joints as well as for sealing penetrations of: metal pipes up to Ø 159 mm, cable trays up to 450 x 50 mm, cable penetrations up to 80 mm. It is also approved for use in conjunction with the FCPS coated panel system.
Formulated from a solvent-free, halogen-free, water-based acrylic base, this intumescent sealant is fire resistant for up to 120 minutes when used in horizontal or vertical construction joints. Once exposed to fire, it reacts to form a highly insulating bead, slowing heat transfer and creating a watertight barrier. FiAM sealant joints have good thermal and acoustic properties and benefit from a high movement capacity of up to 20%. Tested according to NF EN1366-3 and NF EN1366-4, FiAM sealant is also approved for infinite lengths of linear joints by two European Technical Assessments (ETAs) and has a CE mark.

RSMC intumescent silicone sealant:

A single-component silicone sealant, fischer FFRS has fire resistance properties of up to 240 minutes when used in horizontal or vertical construction joints. Tested according to NF EN1366-4, approved for infinite lengths of linear joints and benefiting from an ETA, the FFRS sealant offers excellent adhesion, without primer, on most porous and non-porous materials such as glass, anodized and lacquered aluminum, steel, PVC and concrete. With its halogen-free and solvent-free formulation, it has excellent mechanical properties, resistance to deformation (up to 25%), impermeability to water and air, acoustic and heat.
FFRS sealant can be used indoors and outdoors.

FiGM intumescent graphite putty:

An acrylic sealant based on intumescent graphite, Fischer FiGM sealant complies with NF EN1366-3 and NF EN1366-4 standards and has an ATE; it is intended for sealing metallic and insulated pipe passages up to Ø 159 mm, non-metallic pipes up to Ø 125 mm, cable trays up to Ø 21 mm, etc. Halogen and solvent-free, it has excellent thermal and acoustic properties. It provides fire resistance and smoke tightness for up to 120 minutes.

Two-component polyurethane foam FBS:

fischer FBS-EN expanding foam is a two-component, high-modulus polyurethane foam. It cures by absorbing moisture from the air. Tested according to DIN 4102 and BS 476, fischer FBS expanding foam is suitable for a wide range of applications, such as sealing cable trays, metal and non-metallic conduits, small and medium-sized openings in walls and slabs, etc., and is compatible with a wide range of materials, including concrete, masonry, aerated concrete, plaster, etc. Whether used in walls or slabs, FBS foam fills all voids and provides fire protection for up to 120 minutes. When used in conjunction with FBB fire-resistant bricks, the system is ETA-certified.

Single-component polyurethane foam:

Fischer firestop foam is a foam designed for creating construction joints between walls and slabs, and for joints in non-fire-resistant doors and windows. It cures by absorbing moisture from the air. It has excellent adhesion properties on most construction materials (concrete, cellular concrete, solid masonry, metal, and wood). Once cured, its semi-rigid, closed-cell structure gives it good resistance to vibrations and expansion movements. There is no shrinkage or post-expansion effect after curing. It can be cut, painted, sanded, etc.
Tested according to DIN 4102 and NF EN1366-4 standards and holding a fire report No. 1349C, the foam is fire resistant for up to 240 minutes, it benefits from good acoustic and thermal insulation properties.

FFC fire collar:

fischer FFC intumescent collars are designed for sealing non-metallic pipe penetrations through slabs and walls. They consist of a steel sleeve coated with a graphite-based gasket, which expands under fire to create a tight barrier against gases and fumes that could pass through molten non-metallic pipes. Each FFC collar has been designed to quickly and snugly fit around the pipe and be held in place along concrete walls, solid masonry, or hollow core slabs. By using the integrated fixing lugs, installation on the support prevents the FFC collar from becoming dislodged or displaced during a fire.
Compliant with standard NF EN 1366-3, fischer FCC collars have a fire resistance of up to 240 minutes.

FCPS coated panel system and FPC coating:

Fire-resistant system for sealing service openings. With a rock fiber core covered on both sides with 2 mm of FPC coating, the 1 mm thick fischer FCPS coated panels are lightweight and easy to install. Versatile, they are approved for sealing passages, walls, and slabs. Tested in accordance with NF EN 50-1366, it has good acoustic properties and is fire resistant for 3 minutes. FPC coating is also used to bond assembled FCPS panel sections to maintain fire-resistant performance.

Many other products are available in the fischer FIRESTOP range, to meet all applications: FFB-ES sealant, FFSC fire-resistant mortar, FiPW fire-resistant strips, FiP fire-resistant cushions, etc.
