    Palusol® – The Innovative Solution for Intelligent Fire Protection

      The silicate-based fire-protection panels developed by BASF have proven their reliability a million times for more than 50 years.

    Advantages of Palusol® and Palusol® SW
    High level of fire resistance combined with smoke, sound and/or thermal protection
    Low response temperature and short reaction time
    Minimal component thickness, i.e. low costs of construction and manufacturing combined with greater aesthetic design possibilities
    Preconfigured fire protection door cores allow savings on cost and work intensive process steps
    Certification of products and components ensures high quality standards and allows access to free licences
    Palusol, fire protection, fire-protection panels, fire protection doors

      For more than 50 years, Palusol® panels provide improved fire protection in public and private buildings. Main applications are fire doors, bulkheads and security cabinets.

      Palusol® fire-protection panels are classified as non-combustible building material. In case of fire, the silicate panel expands under the action of heat with generation of foaming pressure. The non-combustible, heat-insulating and pressure-resistant foam prevents fire and smoke from spreading to other rooms for a given period of time by filling joints and gaps. During this process, heat is reduced by evaporating water, thus producing an additional cooling effect. Palusol® is employed in fire-protection doors and glazing as well as in fireproof bulkheads for pipes, cables or ventilation elements.

      Palusol® SW is a ready-made sandwich product composed of Palusol fire-protection panels and high-density fiberboards. The different combination and sequence of the individual layers create a torsion-resistant, flame retardant panel specially developed for the manufacture of fire doors and for use in fire walls.

    Product Range Palusol® and Palusol®SW


      Palusol, fire protection panels

      Palusol® is available from the factory in various thicknesses and dimensions. Treated as raw panel or in strips it can be used in versatile ways and applied  in various fire protection applications.


    Palusol® SW

      Palusol®SW panels were specially developed for the manufacture of fire protection doors and for use in fire protection walls. Fire resistances of between 20 and 90 minutes have been achieved with various combinations of HDF panels and Palusol.

      • Palusol® starts to expand at just 100°C and to develop significant expansion pressure of up to 1.60 N/mm² at 120°C
      • A thermal bond created by evaporating water has an additional cooling effect
      • Reliable fire and smoke resistance for up to 120 minutes
      • Palusol is classified as “non-combustible” corresponding to construction material class A2-s1, d0 pursuant to EN13501-1

    Proven Quality

      • Use of natural and virtually unlimited raw materials (silicate)
      • Durability tests on 40-year-old Palusol® fire protection panels confirm property profile remains unchanged
      • Fire tests on 12-year-old fire protection doors showed that there was no reduction in the fire protection effectiveness
      • The high quality standard is maintained with regular internal and external monitoring

    Experience meets Innovation

      • Tailored solutions possible using different door constructions with Palusol® SW
      • The fire protection know-how is continuously being expanded through value-adding collaboration with customers and fire protection experts
      • Continuous further development of the fire protection-specific property profile of Palusol®
      • Continuous portfolio expansion of tested and certified fire protection doors

    Technical Assessment, Component Testing and Certifications

      • Palusol®

        Palusol fire protection panels for use in “intumescent products for fire proofing and fire retardant applications in case of fire” have a European Technical Assessment and carry the CE label. In addition, the quality is ensured by external monitoring by Underwriters Laboratories.

        Palusol® SW

        Palusol® SW products have been tested in accordance with the following standards and are listed with various testing and monitoring authorities:

        • ASTM (American Society for Testing and Materials)
        • UL (Underwriters Laboratories)
        • NFPA (National Fire Protection Association)
        • CAN/ULC (Standards Council of Canada)
        • BS (British Standards)

        Door manufacturers are provided with free licences of the listed door constructions. In the U.S./Canada, BASF continually conducts tests for the fire door industry based on derived timber products, especially for panel framed doors, of up to 90 minutes’ fire resistance. The detailed CAD drawings of the components are saved in the databases of the various testing institutes:

        In the United Kingdom, Global Fire Resistance Assessments by Exova for 30 minutes and 60 minutes exist for panel framed doors.

        The HDF panels used are sourced from sustainably managed forests, and are labeled and certified with the FSC® logo.



      Palusol is supplied from the factory with an epoxy resin coating on each side. Cut edges which arise during processing must be coated and adequately protected.

      Palusol® fire-protection panels

      • can be cut by means of conventional shears used for sheet meta
      • can be nailed, sawn and drilled
      • can be bonded using adhesives or glues which adhere well to epoxy resin
      • Small parts can be produced using stamping tools
      • When heated to above 60°C, the panels can be readily shaped and can be converted into the desired form by folding, rolling, etc

      Palusol® SW

      • can be worked using standard woodworking machinery (sawing, milling, drilling, etc.)
      • can be adhesively bonded by means of commercial wood glues (white glues)
      • Carbide tipped cutting tools are advantageous in order to obtain longer usage
      • In the case of hot glue processes, it must be ensured that the Palusol layers between the HDFs are not heated to temperatures above 80°C

    Safety precautions

      Sodium silicate dust is created during sawing or milling of Palusol®. It must not get into the eyes or respiratory passages and the use of appropriate extraction facilities and the wearing of safety glasses and a dust mask are therefore advisable. Central facilities as are used, for example, in the woodworking industry are satisfactory for Palusol and Palusol® SW. However, in the case of Palusol® SWR (wire mesh insert), separate extraction systems should be used since there is a risk of sparks being produced.

    Storage and Transport

      Palusol® and Palusol®SW should be protected from water, high atmospheric humidity and sustained temperatures above 40°C. Palusol SW is frost-resistant. The panels should always be stored lying horizontally and supported over their entire area. The wearing of protective gloves is required.


    Applications of Palusol® and Palusol® SW

      Palusol® is applied in the area of fire-protection. Fire doors and glazing as well as in fireproof bulkheads for pipes, cables or ventilation elements prevent fire and smoke from spreading to other rooms for a given period of time. There are also many more potential applications for Palusol fireboard panels, each resulting from efforts to develop functional constructions to prevent or restrict the spread of fire and smoke.

    Fire Doors

      Self-closing barriers designed to prevent the penetration of fire and smoke through openings in walls for a given period of time can be successfully fitted with strips or sections of Palusol®. These are arranged in wooden or steel doors, gateways, and flaps in such a way that, in the event of a fire, they reliably seal off joints and gaps in minimum time. Depending on the construction of the building component, a fire-resistance time of up to 120 minutes is possible.

    Safety cabinets

      Here, again, Palusol® offers consistent protection against fire and prevents the loss of valuable commodities such as money, documents, computer diskettes, etc. stored in safes. When used in cabinets for storing solvents Palusol also ensures safety and prevents the spread of fire of readily ignitable or explosive substances.


    Fire protection walls

      Fire protection walls, palusol, Schörghuber

      Palusol® is also used in fire protection walls to prevent fire from spreading throughout a building by forming fire zones. Similarly, separating walls can also prevent flames and heat spreading in railroad vehicles.
