FAS Fire Door Acrylic 600ml Sealant Kit – White

Yes, architraves can be installed over FAS Fire Door Intumescent Acrylic Sealant where required. However, architraves are optional, as the sealant has been successfully fire tested both with and without architraves as part of a tested fire door sealing system. This provides flexibility when sealing perimeter gaps around fire door frames whilst maintaining the tested fire performance of the installation. Always follow the relevant installation guidance, certification and fire test evidence for the specific fire door assembly.

Yes, FAS Fire Door Intumescent Acrylic Sealant can be used in applications where smoke control is required. The sealant has smoke leakage test evidence in accordance with BS EN 1634-3: 2004, demonstrating its suitability for use as part of a tested fire and smoke sealing system. In addition to providing fire resistance, the sealant helps maintain the integrity of compartmentation by restricting the passage of smoke through joints and perimeter gaps. Always refer to the relevant certification, test evidence and installation guidance to ensure suitability for your specific application.

No, FAS Fire Door Foam™ must be applied to both sides of the door frame and must completely fill the void between the frame and the surrounding wall in accordance with the tested installation method. Using Fire Door Foam™ on one side only and acrylic sealant on the other is not an approved installation configuration.

For gaps up to 5mm, FAS Fire Door Intumescent Acrylic Sealant can be used on its own without the need for a backing material. Always follow the relevant installation guidance, certification and fire test evidence to ensure the correct fire stopping solution is used for the specific gap size and fire door application.

No, FAS Fire Door Intumescent Acrylic Sealant does not require specialist packers or fixings. The sealant has been specifically tested as part of a fire door sealing system in conjunction with FAS Fire Door Foam™, plastic packers and standard screw fixings. Timber packers and MDF packers may also be used where required. Always ensure installation is carried out in accordance with the relevant fire test evidence, certification and installation guidance to maintain the fire and smoke performance of the door assembly.

Yes, FAS Fire Door Intumescent Acrylic Sealant has a shelf life of up to 18 months when stored unopened in temperate conditions between 5°C and 30°C. To help maintain product performance and longevity, the sealant should be stored in a cool, dry environment and protected from extreme temperatures. Always check the product packaging and technical documentation for storage recommendations before use.

Yes, FAS Fire Door Intumescent Acrylic Sealant offers acoustic performance with sound reduction capabilities of up to 55dB Rw. In addition to providing a fire-resistant seal around joints, gaps and fire door installations, the sealant can help reduce the transmission of airborne sound through openings in walls and building elements. For full acoustic test data, installation guidance and certified performance information, please refer to the product datasheet.

FAS Fire Door Intumescent Acrylic Sealant has been fire tested to provide 30, 60, 90 and up to 120 minutes of fire resistance in timber fire doors and timber glazed screens. The sealant has been tested in accordance with BS 476: Part 20 & 22: 1987 and BS EN 1634-1, demonstrating its suitability for use as part of a tested fire door sealing and fire stopping system. The achievable fire rating will depend on the application, gap size and installation configuration. Always refer to the relevant certification, fire test evidence and installation guidance for the specific fire door assembly.

FAS Fire Door Intumescent Acrylic Sealant can be used to seal gaps up to 5mm wide without a backing material. For larger gaps, the sealant has been tested for use in gaps up to 25mm wide when installed in conjunction with FAS Fire Door Foam™ or stone mineral fibre wool as part of a tested fire door sealing system. Always refer to the relevant fire test evidence, certification and installation guidance to ensure the correct sealing method is used for your specific fire door application.

FAS Fire Door Foam™ is a fire-rated expanding foam designed to simplify fire door installation and fire-stopping applications. Compared to traditional stone mineral fibre wool, it offers a quicker and more cost-effective installation method, helping to reduce labour time and overall project costs. When used with FAS Fire Door Intumescent Acrylic Sealant, it forms part of a tested fire door sealing system for perimeter gap sealing around fire door frames.

Selecting the correct fire-rated sealants for a fire door installation is essential to maintaining the fire performance of the door assembly and helping to prevent the spread of fire and smoke.

When sealing gaps between the fire door frame and the surrounding wall, it is important to use products that have been tested in fire door assemblies and comply with the recommendations of BS 8214:2016.

When choosing a fire-rated sealant, check that:

• Fire-rated mastics have been successfully tested as a linear gap seal in accordance with BS 476-20 or BS EN 1366-4 for the required fire resistance period.
• Fire-rated expanding foams have been successfully tested as a linear gap seal in accordance with BS 476-20 or BS EN 1366-4 and provide a minimum of 30 minutes fire resistance.
• The sealant has been included within a fire test between the door frame and surrounding structure on a timber-based fire door assembly tested in accordance with BS 476-22 or BS EN 1634-1.

If a product does not provide this information, you should request the relevant fire test evidence and certification before specifying or installing it.

FAS Fire Door Foam™ and FAS Fire-Rated Acrylic Sealant have been independently tested for use in fire door assemblies and are Certifire approved under certificates CF5839 and CF5840. When used individually, both products can provide up to 60 minutes of fire protection. When used together as a tested system, they can achieve up to 120 minutes of fire resistance.

Typical applications include:

• FAS Fire Door Foam™ for gaps up to 25mm to achieve up to 60 minutes of fire protection.
• FAS Fire-Rated Acrylic Sealant for gaps below 5mm to achieve up to 60 minutes of fire protection.
• A minimum 10mm cap of FAS Fire-Rated Acrylic Sealant over FAS Fire Door Foam™ to achieve up to 90–120 minutes of fire protection.
• Installation with standard packers as part of the tested system.

FAS Fire Door Foam™ also replaces the need for mineral fibre wool, helping to reduce installation time by approximately 12 minutes per doorset installation.
