Certified Pipe Penetration Firestops with MARVON Systems
TECNOCOLLAR
Firestop Collars for Plastic Pipes (PVC, PE, PP).
Made of graphite-based intumescent material enclosed in a steel casing.
Installed around the pipe at the penetration point, they activate with heat to completely seal the opening. Ideal for both walls and ceilings
.
PIPEWRAP
Marvon Intumescent Wrap Tape for pipe sealing, suitable for fire resistance requirements up to EI240.
Applied around the pipe, it activates at high temperatures, expands, and fully seals the penetration opening.
TECNOBOARD + TECNOWRAP
Tecnoboard provides a stable sealing base with high mechanical strength, while Tecnowrap, made of graphite-based intumescent material, wraps around the pipe and expands in the event of a fire, sealing the opening.
TECNOGRAPHIT
Two-component polyurethane foam by Marvon, enhanced with graphite, specifically designed for use as a firestop in pipe penetrations.
Provides certified fire resistance up to EI180 in wall and floor systems, in accordance with EN 1366-3.
TECNOBRICK
Spongy, intumescent polyurethane firestop brick by Marvon, ideal for quick and easy sealing of openings.
Easily shaped by hand to fit irregular or uneven openings. When exposed to fire, it expands and seals the gap, preventing the spread of flames, smoke, and gases.
TECNO-S 240
Single-component acrylic sealant by Marvon, specially designed for passive fire protection applications.
Certified according to EN 1366-3 and EN 1366-4, Tecno-S is easily applied with a standard caulking gun and remains elastic, ensuring stability and tightness even in cases of vibration or thermal expansion.
Pipe Systems Covered
Plastic Pipes
(PVC, PE, PP, PEX, etc.)
The most challenging to seal due to melting at high temperatures.
Commonly used in water supply, drainage, and heating systems.
Metal Pipes
(steel, galvanized, copper, stainless steel – INOX)
Heat-resistant, but require thermal insulation materials and certified solutions to fill the gap between the pipe and the wall.
nsulated Pipes
(with thermal or acoustic insulation)
Commonly used in HVAC systems. The insulation increases the complexity of firestopping and requires advanced solutions using rock wool and coatings.
Fire Suppression Pipes
High-pressure metal piping, typically routed through technical areas and shafts. Proper firestopping is critical to maintaining system integrity.
Natural Gas Pipes
Firestopping in natural gas networks requires certifications to ensure tightness and safety. In certain cases, we can propose tailored solutions based on the project requirements and the existing design.
Air Conditioning & Cooling Pipes
(chilled water lines, VRV, VRF)
These include plastic or metal pipes with insulation. They often pass through false ceilings or shafts and require specialized firestopping solutions involving a combination of insulating materials, enclosures, and fire-resistant coatings.
Pipe Penetration Firestops
Pipe penetration firestops are specialized passive fire protection systems installed where pipes pass through fire-rated walls or ceilings. Their purpose is to prevent the spread of fire and smoke through these openings, providing certified fire resistance in accordance with EN 1366-3.
Frequently Asked Questions about Pipe Penetration Firestops
For plastic pipes, solutions such as Tecnocollar or Pipewrap are used. These activate with heat and fully seal the penetration opening.
For metal or fire-resistant pipes, solutions such as Tecnoboard with Tecnowrap, Tecnographit, or Tecno-S are applied. These seal gaps and maintain the fire resistance of the separating element.
Insulated pipes require more complex solutions, such as Tecnoboard with Tecnowrap, or filling with rock wool and coating, to ensure fire tightness and mechanical stability.
All our Marvon products are fully certified according to EN 1366-3 and EN 13501-2, with documented fire resistance for both walls and floors, up to EI240.
Depending on the material and firestopping method used, we can achieve fire resistance ratings from EI60 up to EI240, based on technical assessment and installation conditions.
Yes. Our team can assess the penetrations on-site and recommend the most suitable certified solution based on your project’s requirements.
