Testing Methodology: BS EN 1363-1 AND BS 476-20
• Knauf interior drywall partition systems* that achieve a fire resistance performance are tested in accordance with BS EN 1363-1 and BS EN 1364-1. These are the up to date and most rigorous test methodology standards to follow.
• Determining the maximum height of a drywall partition as per the BS EN 1363-1 fire test methodology, is typically restricted by the 3 metre height of the test furnace.
• To understand the true maximum height of the system whilst under fire test conditions (‘Fire State Height’), there are three options. Increases can be determined by utilising greater test furnace heights, via Extended Field of Application (as outlined in BS EN 15254-3 - it is important to note this standard applies to single metal frame symmetrical systems only), or via BS EN 1364-1.
• The BS 476-20 standard is also restricted by the 3 metre height of the test furnace. However, under this BS standard, increasing the maximum heights of a system can be based on the ‘Cold State Height’. The cold state height is calculated using structural engineering methods to L/240 @ 200Pascals. (L = Height of wall).
Regulatory Requirements
• Specific to Approved Document B (England) there is a requirement to use European classifications and fire resistance test methodologies in accordance with BS EN 1363-1 and BS EN 1364-1, which means that the fire state height must be considered. However, Approved Document B (England) currently allows the usage of the BS 476 series, though it should be noted that, following consultation, the full BS 476 series will be removed in 2029. For other nationals, please consult relevant approved documents, technical guidance, and handbooks.
Knauf Approach & Recommendations
• Knauf advise and promote that EN compliance should be followed. That is to say Knauf advise utilising an EN 1364-1 fire resistance test and extend the maximum height of a drywall partition system via either BS EN 15254-3, BS EN 1364-1 or via a fire resistance test within a test rig greater than 3m in height.
• Projects that wish to use the BS 476 series must gain agreement between the Client, Accountable Persons, Duty Holders, and Local Building Control that the cold state height is an acceptable methodology.
For further information on Knauf system types that are applicable to support projects focusing on EN compliance, refer to Knauf EN Compliance Systems document, available at Compliance-documents or contact Knauf Technical Services – technical-uk@knauf.com or via telephone 0800 521050 (option 2).

An introduction to Knauf Drywall Systems
Knauf Performer Partition and Knauf Performer Hybrid Partition
The Knauf Performer system is our most versatile and commonly used partition system. It is constructed using a single row of Knauf metal studs with Knauf plasterboards to both sides in order to meet fire, acoustic, moisture and impact requirements. The Performer system is lightweight, simple to construct and should be used in conjunction with Knauf’s finishing solutions range.
Knauf Performer Partition with Knauf Resilient Bar
Knauf Resilient Bar can be added to both or one side of certain Knauf Performer systems. This additional component improves the acoustic sound reduction performance of the system in order to meet higher acoustic requirements.
The Knauf Isolator system is typically used to divide habitable dwellings. The twin stud build up, combined with Knauf’s high performance plasterboards, maximises acoustic performance in order to comply with building regulations, technical handbooks and guidances for sound insulation.
Knauf Shaftwall
Knauf Shaftwall is our innovative system to form enclosures around service and lift shafts while working from one side. The unique Knauf ‘CT’ Stud makes this possible with a minimum of components. The system can provide a high level of fire resistance performance to meet the requirements of your project.
Knauf Horizontal Shaftwall - Ceiling System
Knauf Horizontal Shaftwall - Ceiling System is our innovative, non-loadbearing independent ceiling system (membrane) providing fire resistance from below and or from above. The unique arrangement allows the system to be built from one side.
Knauf Smokeshaft
Knauf Smokeshaft is a system to be used when an A1 fire classification board (in accordance with BS EN 13501-1) is required to line a shaft.
Knauf ‘I’ Stud Linings
Knauf Independent ‘I’ Stud is a fully independent wall lining system that can be used in all building types to upgrade the acoustic, fire and thermal performance of an existing masonry wall and to deal with any irregularities. Due do the system using an Knauf ‘I’ Stud, there is no requirement for the lining system to be fixed back into the structure behind.
Knauf AQUAPANEL® Cement Board Indoor Board
/ Interior System
Knauf AQUAPANEL® Cement Board Indoor is exceptionally tough and durable, providing a solid tile backing substrate for wet indoor areas such as swimming pools, leisure centres, bathrooms and kitchens. The board is used in conjunction with specialist screws and finishing products to provide a full Knauf solution for humid and wet conditions.
Knauf Framed Encasement System – Fire Panel
Knauf Framed Encasement System is a specialist fire protection encasement system designed to protect loadbearing universal beams and or columns. The use of Knauf Fire Panel plasterboard and specialist encasement Knauf components provide a simple and easy to install system.
Knauf Metal Furring (MF) Suspended Ceiling System
The Knauf Metal Furring (MF) Suspended Ceiling system is versatile and easy to install. Deep voids are easily created to hide services and the ceiling can be used to provide fire protection to the soffit above. The Knauf MF Suspended Ceiling system is very familiar to contractors who will easily be able to form openings, bulkheads and coffers.

Knauf Framed Encasement System – Fire Panel
The Knauf Framed Encasement System – Fire Panel can be used to protect load-bearing universal steel beams and columns for up to 120 minutes load-bearing capacity which has been tested in accordance with EN 13881-4. The system comprises of specialist Knauf metal components which are attached to the steels creating a substructure for the Knauf Fire Panel plasterboards to be fixed to using Knauf drywall screws. All plasterboard joints must be taped and filled using Knauf jointing compounds. The plasterboards can be then be treated to the desired finish.
To help specify the required thickness and number of layers of Knauf Fire Panel for universal steel beams and columns with your required fire protection it is important to understand and obtain the following:
1. What type of steels require protecting? Is it...
• Hot finished / formed structural hollow sections
This is important as it will,
• Assist in understanding the number of how many sides of the universal beams or columns are required to be protected
• Help to understand the critical design temperatures and the variable load factors, the universal beams or columns will be subject to.
Note: In accordance with A.3.2, ASFP Yellow Book – Fire Protection for structural steel in buildings 5th edition (Volume 1 of 2), guidance is given to obtain the default critical temperature from Eurocodes if you know the building type, usage area and what steels are required protecting. See Table 16. If you do not know the building occupancy, a following table 17, provides the critical temperature from the Eurocodes.
2. What is the Hp/A factor? This is a critical parameter in structural fire engineering, when assessing the fire protection requirements for structural steel beams and columns. It is representing the section factor, which relates the heated perimeter (Hp) of the steel member to its cross-sectional area (A). This ratio influences how quickly the steel member will heat up in a fire and, consequently, how much fire protection it will need. The Hp/A factor for various universal beams and columns can be found within ASFP Yellow Book – Fire Protection for structural steel in buildings 5th edition (Volume 1 of 2). This should be referenced, whilst knowing the required size, mass, depth, width and thickness within Table A.2 for UK Beams (UKB) and Table A.3 Columns (UKC).
By understanding whether it is a universal beam or column, the size, mass and dimensions of the steel it is possible to obtain the Hp/A factor by cross-reference Table A.2 and A.3.
*Tables are extracted from section A.3.2 of ASFP Yellow Book – Fire Protection for structural steel in buildings. 5th edition (Volume 1 of 2) The system has been designed to meet project requirements of BS EN 1991-1 (Eurocode).

Knauf Framed Encasement System – Fire Panel
By knowing what steels (‘I’ and ‘H’) are required to be fire protected on your project, critical design temperatures and obtaining the Hp/A factor, dependent on size, mass and dimensions of your steels, you can specify the Knauf Framed Encasement System – Fire Panel system.
Tables A, B, and C, provide the Knauf plasterboard specification against the fire resistance period (minutes). The denoted Hp/A values stated are the maximum acceptance for the specification solutions. Therefore, any steels less than or equal to this value allows you to specify the number and layer of Knauf Fire Panel.
Let’s carry out some examples:
Example 1
You are required to provide fire protection (load-bearing capacity) of 60 minutes to a composite beam supporting a concrete slab, you know that the building occupancy is domestic, requiring critical design temperature 576°C as per Table 16 (page 22). The universal structural beam is 254 x 102 x 22 and requires 3-sided protection. By referring to Table A.2 (page 23) the Hp/A factor can be confirmed as 220.
By cross-referencing to Table A and B (critical design temperature solutions above 576 °C) it is acceptable to specify 2 x 12.5mm Knauf Fire Panel. The Hp/A value must be greater to the Hp/A value for the steel.
Example 2
You are required to be provide fire protection (load-bearing capacity) of 90 minutes to a composite beam supporting a concrete slab, you do not know the building occupancy and therefore, as per Table 17 (page 22), the critical design temperate to follow is 550 °C.
The universal structural beam is 254 x 146 x 31 and requires 3-sided protection. By referring to Table A.2 (page 23) the Hp/A factor can be confirmed as 165.
By cross-referencing to Table C (critical design temperature solutions 550 °C) it is acceptable to specify 2 x 12.5mm Knauf Fire Panel. The Hp/A value must be greater to the Hp/A value for the steel.
Important
The critical design temperatures of steel sections will vary on a project to project bases, dependent on location and intended use, and therefore you must consult with the structural engineer to gain confirmation the specific design temperatures that you need to use to help the determine your fire protection solution.
