Fire Protection - Fire Stopping and Fire Prevention

Fire Protection

With nationwide coverage, Kilnbridge works closely with clients, contractors, architects, and developers to develop appropriate, cost-effective fire protection systems tailored to each building.

We maintain close relationships with leading manufacturers to develop bespoke fire protection solutions. Early planning and preparation can help prevent many onsite alterations and unplanned openings, therefore reducing the need to amend the approved design.

If fire protection is missing or poorly installed, compartmentation failure can happen. It is vital that all protection measures are correctly designed, specified and installed. By their nature, they are ‘passive’ until there is a fire and only then will their fire performance in-situ be demonstrated.

Our Accreditations

We are FIRAS accredited installers of fire protection systems which provides our clients with the assurance that our installers, supervision and management systems continue to meet industry specific standards. FIRAS certification has been instrumental in improving standards of installation of fire protection products and systems to the benefit of the construction industry and the clients it serves.

In addition, we are a full member of the Association for Specialist Fire Protection (ASFP). As the UK’s leading trade association relating to built-in fire protection, the ASFP is dedicated to the protection of life, property, the environment and our heritage and promotes continuous improvement in all aspects of passive fire protection. The ASFP strives to promote excellence in the design and installation of fire protection products through high quality and technical expertise by fostering the education and training of all those involved in the development, specification and use of built-in fire protection.

The objective of fire compartmentation is to prevent the rapid spread of smoke and fire. We carry out comprehensive visual inspections of the existing fire stopping installations within the following areas; floors, walls, roof voids, basements, floor and ceiling voids, risers and shafts where present.


We offer a full range of board products providing solutions to meet a variety of installation and fire protection needs. Fire protection boarding can be used for wind posts, column encasement, beam encasement, additionally see Durasteel section below. Kilnbridge offers one of the most complete ranges of boarding solutions within the market.


Penetration seals are used to maintain the fire resistance of a fire-separating element at the position where one or more services pass through or where there is provision for services to pass through a fire-separating element. We supply and install batts, compounds, collars, wraps and transit systems to maintain the fire rating of the penetrated element. The importance of sealing any gaps in fire-resisting constructions is vital to ensure the fire strategy performs in accordance with the design and its ability to save life and property.


Wall and soffit insulation systems can provide thermal, fire and acoustic properties in areas of a structure where the prevention of condensation or cold bridging may also be a requirement. We offer a number of solutions to address the increasing requirement for thermal upgrading and fire protection of walls and soffits. The durability of the product increases further when used in combination with a 6mm non-combustible high impact facing option, typically used in basement and underground car parks.


Steel faced boards, such as Durasteel, are manufactured from a non-combustible core, which is usually cementitious based, onto which steel sheets are mechanically bonded; known as impact boards. Impact Board systems are typically used to construct walls and standalone barriers, ceilings, roofs, stairwells and ductwork or cable protection for use where aggressive environmental conditions prevail, particularly where high impact resistance or blast resistance is required. Durasteel is also UKPN approved for use in substations with ratings of up to 4 hours.


We are third-party accredited under the BM TRADA Q-Mark Fire Door Installation and Maintenance schemes. As a vital element in the overall fire strategy of a building, fire doors must be managed and maintained to ensure that they can perform as expected in the event of a fire. We offer a range of maintenance options tailored to client requirements to ensure their building remains compliant. All fire doors in the building should be inspected regularly, and a check will need to be made to verify them.

Cavity barriers are passive fire protection elements that prevent flames and smoke from spreading via the walls. They work by sealing the voids in a cavity during a fire. Kilnbridge supply and install passive fire protection seals to floor slab edges to provide up to 120 minutes of fire resistance in all forms of approved cladding application designs.


Kilnbridge are a licensed installer of Cafco FENDOLITE® MII. This form of fire protection can often be seen in places like multi-storey car parks and basement areas of buildings, where a very rough and thick coating is spray applied to the profile of the steel. Cementitious sprays are an extremely effective fireproofing solution for steel and concrete structures.


Intumescent coatings have been a leading form of passive fire protection of steel frame buildings for over 30 years. They function by expanding when exposed to fire, producing an insulating char layer that delays the heating of the steel. This preserves the structural integrity of the building for an extended period of time.


Fire barrier systems are essential to prevent the rapid spread of flames and inhibit heat and smoke through concealed spaces within buildings. These barriers can also provide a level of sound reduction by creating compartments within the buildings floor and roof spaces. Kilnbridge supply and install fire barriers which can be designed to provide acoustic performance and compartmentation of large, concealed spaces (extensive cavities) within a building
