Why Choose Ark Fire Protection Fire Stopping Products?
Today’s buildings use a lot more combustible materials than in the past. In fact, fires in modern buildings can spread 5 to 10 times faster than before, according to CTIF.org. That makes fire protection more critical than ever.
New constructions also have lots of pipes, HVAC ducts, and other installations running through walls and floors. These create “weak spots” where smoke, heat, and flames can sneak through if not properly sealed.
With years of expertise and experience working on countless projects across the UK, our team at Ark Fire Protection knows exactly how to tackle these challenges. Our fire stopping products and services seal those gaps and reinforce weak points, blocking hot gases, toxic smoke, and flames from spreading – keeping your building and neighbours safer.

Inadequate protection around service risers can put buildings at risk of fire spread. Load-bearing fire compounds are specially formulated with a gypsum-based compound. When set the compound becomes hard and reinstates the fire ratings of walls and floors depending on specification from the client.
At Ark Fire Protection we work closely with some of the leading manufacturers and products. Ark are third party accredited for application of compound fire seals. For more information contact or team.
Any surfaces that penetrate a fire wall will result in a spread of fire and smoke. Batt and Mastic Seals provide an innovative air seal barrier to keep fire out, but sound and heat in. Following the latest industry guidelines we can incorporate deflection that the surfaces have going through penetrations.
Here at Ark Fire Protection we work closely with leading manufacturers. Our team are the third-party accredited for all passive fire protection works.
Graphites are high specification formulas designed to prevent the spread of fire, smoke and harmful gasses through an opening situated in fire-rated walls and floors.
Graphites expand when they are subjected to heat to close openings around penetrations when combustible or materials with low melting temperatures burn away. In the event of a fire the material crushes the pipe or trunking, sealing off this area and maintaining the integrity, which comes in handy in multiple service penetration and cable bunches.
Pipe Wraps are designed for installation around plastic piping or trunking passing through fire resistant structures such as walls and doors. During the primary construction phase of a product, i.e. casting floors, an additional tolerance is in built to enable the fitting of Pipe Wrap once the mechanical and electrical services have been installed.
In the event of a fire the contained intumescent material rapidly expands and crushes the pipe or trunking, sealing off this area and maintaining the integrity.
Flexible linear joint seals within wall cavities and voids are important in reducing the damaging effects of fire and smoke. Joint seals are designed to accommodate structural movement whilst maintaining fire performance of walls and floors.
Here at Ark, we work with leading manufacturers and are the third party accredited for the installation of linear joint seals.
Fire stopping in the UK is primarily governed by the Regulatory Reform (Fire Safety) Order 2005 and the Building Regulations 2010 (Approved Document B). Together, these form the foundation of passive fire protection compliance.
The Fire Safety Order places a legal duty on the “Responsible Person” — typically the building owner, employer, or manager — to ensure that fire safety measures, including fire stopping systems, are correctly installed, maintained, and effective in preventing fire and smoke spread.
Approved Document B provides the technical standards and performance criteria for fire resistance, compartmentation, and the protection of escape routes. It specifies how penetrations in fire-rated walls, floors, and ceilings — such as pipes, ducts, and cables — must be properly sealed using tested and certified fire stopping products.
In practice, compliance means selecting systems that have been third-party tested and certified to BS EN standards, ensuring compatibility with surrounding building materials, and maintaining accurate documentation for inspection. Regular maintenance and re-certification are essential to uphold integrity throughout the building’s life cycle.
Fire stopping is a critical part of passive fire protection, designed to contain fire and smoke at their point of origin. Effective fire stopping:
Fire stopping is essential across all types of buildings to ensure safety, compliance, and protection of assets. From commercial developments to healthcare facilities, each environment has unique fire safety requirements that demand sector-specific solutions. Our fire stopping services are tailored to meet the distinct needs of every sector we work with:
Approved Documents guide how to meet the building regulations. Part B contains guidance on fire safety, including means of escape, fire spread, structural fire protection and fire service access. The Approved Document can be downloaded below, with volume 1 covering dwellings and volume 2 covering buildings other than dwellings (including flats).
The Part B Volume 1 fire safety document is a section of the Building Regulations in the UK that provides guidance and requirements for fire safety in dwellings, including houses and flats. It covers topics such as means of escape, fire resistance, fire detection systems, and firefighting equipment.
Part B Volume 2 addresses fire safety for buildings other than dwellings, which includes flats, offices, shops, and public buildings. This volume provides detailed guidance on fire compartmentation, the design of fire exits, smoke control systems, and access for firefighting services. It also outlines requirements for limiting fire spread across external walls and roofs, ensuring that fire and smoke can be contained effectively in different areas of the building.
Ark closely follows the premise set out in the Golden Thread
The fire stopping process begins with a thorough assessment and survey. Our team conducts a comprehensive site inspection to identify all potential fire stopping requirements. This detailed examination allows us to understand the unique needs of your building and ensures no critical areas are overlooked. Following the inspection, we provide a detailed assessment report complete with our findings and expert recommendations. This report serves as the foundation for developing a customised fire stopping plan that effectively mitigates fire risks.
The next step in the fire stopping process is the design and planning phase. We create a bespoke fire stopping plan tailored specifically to your building’s design and usage. Our team collaborates closely with architects and construction teams to integrate our fire stopping solutions seamlessly into the overall building plan. This coordination ensures that our fire stopping measures are both effective and aesthetically aligned with the building’s architecture.
Once the design is finalised, we move on to the installation phase. Our skilled professionals handle the installation of fire stopping systems with precision and care. We ensure that every component is installed correctly and efficiently, adhering to all relevant safety standards. Throughout the installation process, on-site supervision is maintained to guarantee that the work meets our rigorous quality and safety criteria.
Ark’s commitment to fire safety extends beyond the initial installation. We offer regular inspection and maintenance services to ensure the continued effectiveness of our fire stopping systems. With Ark, you can have peace of mind knowing that your building is protected by a robust and well-maintained fire stopping system.
Fire stopping is a passive fire protection method that seals gaps and penetrations in fire-rated walls, floors, and ceilings. It prevents the spread of fire and smoke between compartments, protects escape routes, maintains structural integrity under fire conditions, and ensures compliance with UK fire safety regulations.
Materials include intumescent sealants and mortars, fire-resistant boards and blankets, fire collars for pipes, and mineral wool for cavity filling. Each material is selected based on the type of penetration, surrounding construction, and required fire rating to provide tested and certified protection.
Fire stopping should be inspected at least annually or following any building alteration, maintenance, or refurbishment. Regular inspections verify that materials remain intact, compliant, and effective, and that any penetrations introduced over time are correctly sealed.
The “Responsible Person” under the Regulatory Reform (Fire Safety) Order 2005—typically the building owner, manager, or employer—is legally accountable for ensuring fire stopping is correctly installed, maintained, and documented throughout the building’s life.
Yes. Fire stopping can be retrofitted in existing buildings to close unsealed gaps or upgrade non-compliant systems. Retrofits must be designed to meet current fire ratings and tested standards without compromising existing structural integrity.
Fire stopping is governed by the Regulatory Reform (Fire Safety) Order 2005 and Building Regulations (Approved Document B). Products must be tested to BS EN 1366 series standards for penetrations and linear joints, and installations must comply with manufacturer guidance and fire strategy requirements.
