Our Passive Fire Protection Services

Passive fire protection plays a critical role in slowing the spread of fire and smoke throughout a building, helping to protect occupants, safeguard property and maintain compliance with fire safety regulations. Our passive fire protection services are designed to preserve the integrity of fire compartments and ensure that walls, floors, doors and service penetrations continue to perform as intended in the event of a fire.

At Thameside Fire Protection, we provide comprehensive passive fire protection solutions, including fire stopping, compartmentation, fire doors, fire and smoke barriers, intumescent products and ongoing inspection and maintenance services. Working across commercial, industrial, residential and public sector environments, our certified team delivers high-quality installations and remedial works that help buildings remain safe, compliant and protected

Fire doors

The main functions of a good fire door are to reduce the spread of fire between rooms and to protect escape routes, allowing you and your team to quickly and safely exit the premises. At Thameside Fire Protection, we carry a wide selection of fire doors that are manufactured from the finest quality products. Our doors come with a variety of special features like automatic closing devices and intumescent seals and can be tailored to suit all environments. We also supply colourful emergency signage to ensure that everyone knows what to do and where to go in the event of fire.

Step 1 3

  • Site Survey & Fire Compartmentation Assessment

    We begin with a detailed site survey to assess fire compartmentation, structural vulnerabilities, and compliance with UK building regulations. Our team identifies areas requiring fire-stopping, fire doors, and other passive fire protection measures.

  • Installation of Fire-Resistant Materials

    We install certified fire-resistant materials including fire-stopping sealants, fire doors, intumescent coatings, and cavity barriers. All installations are carried out to meet BS476 and EN standards for passive fire protection.

  • Inspection, Certification & Maintenance

    After installation, we conduct thorough inspections and provide certification for compliance. We also offer ongoing maintenance and re-certification services to ensure long-term fire safety and legal adherence.

Intumescent products

Though intumescent products remain passive in normal temperature conditions, they come to life in the extreme heat of a fire, swelling to fill gaps and preventing the passage of smoke and hot gases. If you’re looking for high-quality intumescent products to complement your existing active fire systems, then look no further than Thameside Fire Protection. We have all the supplies you need to help ensure your building’s fire resistance, including:

  • Fire pillows and pads
  • Pipe wraps and collars
  • RSB
  • Fire barriers
  • Passive board
  • Acrylic sealant
  • Fire compound
  • Door seals
  • Downlight covers and fire hoods
  • Electrical socket inserts and covers
  • Air transfer grilles

Fire-stopping and compartmentation

Fire-stopping and compartmentation are essential elements of an effective passive fire protection strategy. Designed to restrict the spread of fire and smoke through a building, these measures help protect escape routes, limit property damage and provide occupants with valuable time to evacuate safely.

Over time, fire compartments can become compromised by building alterations, service installations and general wear and tear. Gaps around pipes, cables, ductwork and other penetrations can reduce the effectiveness of fire-resistant walls and floors if they are not properly sealed.

At Thameside Fire Protection, we carry out compartmentation surveys, remedial works and fire-stopping installations to help restore and maintain the integrity of fire compartments. Our team uses certified fire-stopping systems and materials to ensure penetrations and construction joints meet the required fire resistance standards and support ongoing compliance with fire safety regulations.

Certified Passive Fire Protection Contractors

When it comes to passive fire protection, the quality of installation is just as important as the products themselves. Incorrectly installed fire-stopping systems, fire doors or compartmentation measures can compromise a building’s fire strategy and reduce the effectiveness of its fire resistance measures.

Thameside Fire Protection is certified to LPS 1271 and LPS 1197 standards, demonstrating our commitment to delivering passive fire protection works to recognised industry benchmarks. These third-party certifications provide reassurance that our installations, processes and quality management systems are independently assessed and regularly audited.

Our experienced team works closely with building owners, facilities managers, contractors and duty holders to deliver compliant passive fire protection solutions across commercial, industrial, residential and public sector environments. From surveys and remedial works to installation, inspection and maintenance, we help ensure passive fire protection systems continue to perform as intended throughout the life of a building.

What is passive fire protection?

Passive fire protection refers to measures built into the structure of a building to help prevent the spread of fire and smoke. This includes fire doors, fire-stopping systems, compartmentation, fire barriers and intumescent products.

What is the difference between passive and active fire protection?

Passive fire protection is designed to contain fire and smoke within a building, while active fire protection systems such as fire alarms and sprinklers require activation to detect, control or suppress a fire.

Why is fire compartmentation important?

Fire compartmentation helps prevent the spread of fire and smoke by dividing a building into separate fire-resistant sections. This helps protect escape routes, limit damage and provide occupants with more time to evacuate safely.

What is fire stopping?

Fire stopping involves sealing gaps and openings around pipes, cables, ductwork and other building services to maintain the fire resistance of walls and floors and prevent the spread of fire and smoke.

How often should passive fire protection systems be inspected?

Passive fire protection systems should be inspected regularly as part of a building’s fire safety management plan. The required frequency will depend on the building type, occupancy and any changes that may affect fire compartments or fire-resistant elements.

Can damaged fire-stopping or compartmentation be repaired?

Yes. Damaged or non-compliant fire-stopping and compartmentation can often be repaired through remedial works. A compartmentation survey can help identify defects and determine the appropriate corrective action.

What certifications should a passive fire protection contractor hold?

Third-party certifications such as LPS 1271 and LPS 1197 demonstrate that a contractor’s processes, workmanship and quality management systems have been independently assessed against recognised industry standards.

Do passive fire protection systems help with legal compliance?

Yes. Effective passive fire protection measures can help building owners and responsible persons meet their obligations under fire safety legislation and demonstrate that reasonable steps have been taken to protect occupants and property.
