Assessment criteria
Quick Revision Summary (Key Takeaway)
The Highfield Level 2 NVQ Diploma in Interior Systems (Construction) – Dry Lining – Fire Resistant Walls (RQF) covers the skills and knowledge required to install fire-resistant dry lining systems, including fire-resistant boards, framing, and jointing, in compliance with UK building regulations and safety standards. This qualification is essential for construction professionals specialising in passive fire protection, ensuring that walls meet fire-resistance ratings and contribute to overall building safety.
Topic Overview
This unit focuses on the installation of fire-resistant dry lining systems, which are critical for passive fire protection in buildings. Fire-resistant walls are designed to contain fire and smoke within a compartment, allowing occupants to escape and reducing property damage. The qualification covers the principles of fire resistance, the properties of fire-resistant boards (such as Fireline or equivalent), and the correct installation techniques for metal stud frames, including fixing, jointing, and finishing.
Students will learn about the relevant building regulations, including Approved Document B (Fire Safety) in England and Wales, and the importance of following manufacturer's specifications to achieve the required fire-resistance ratings. The unit also emphasises health and safety, as working with large boards and power tools carries risks. Understanding the science of fire resistance—how heat transfers through materials and how boards protect the structure—is essential for making informed decisions on site.
This knowledge is applied in real-world scenarios, such as constructing partition walls in commercial buildings, corridors, and stairwells. The skills gained are highly valued in the construction industry, as fire safety is a legal requirement. Mastery of this unit demonstrates competence in a specialist area of dry lining, enhancing employability and career progression.
Key Concepts
Core ideas you must understand for this topic
- →Fire-resistance ratings (e.g., 30, 60, 90 minutes) and how they are determined by the entire wall system, not just the board.
- →Properties of fire-resistant boards: e.g., Fireline, which contains glass fibre and other additives to improve fire performance.
- →Correct installation of metal stud frames, including spacing, alignment, and fixing methods.
- →Jointing and finishing techniques using fire-resistant jointing compound and tape to maintain the integrity of the fire barrier.
- →Sealing penetrations (e.g., pipes, cables) with intumescent materials to prevent fire and smoke spread.
Learning Objectives
What you need to know and understand
- Interpret technical drawings and manufacturers' instructions to identify fire-resistant wall components.
- Apply health and safety legislation and site-specific risk assessments when constructing fire walls.
- Select and handle fire-rated plasterboard, insulation, and fixings in accordance with job specifications.
- Apply methods to protect finished surfaces and adjacent areas from dust, impact, and contamination.
- Demonstrate the ability to sequence tasks and coordinate with other trades to meet project deadlines.
- Verify that installed fire walls meet the required fire resistance period and contractual specifications.
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for correctly interpreting fire strategy drawings and identifying fire resistance periods.
- Credit demonstration of using appropriate fire-rated materials as per manufacturer's instructions.
- Expect candidates to show consistent use of personal protective equipment and safe tool handling.
- Look for evidence of protecting adjacent surfaces with dust sheets and segregation measures.
- Assess ability to calculate material quantities from drawings and minimise waste.
- Evidence of checking work against quality standards, such as level, plumb, and joint sealing.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always cross-reference the contract specification with the fire strategy before commencing work.
- 💡Demonstrate consistent checking of plumb and level to ensure fire integrity of wall alignments.
- 💡Keep a detailed record of material batches and installation checks to support quality assurance.
- 💡Show awareness of critical interfaces with other trades, such as ceiling fixers and electricians.
- 💡Always refer to the manufacturer's system specification when answering questions about fire-resistance. Examiners look for evidence that you know the importance of following tested systems.
- 💡Use correct terminology: 'fire-resistant board', 'intumescent sealant', 'fire-stopping', 'compartmentation'. This shows professional knowledge.
- 💡In practical assessments, pay attention to the spacing of screws and the staggering of joints—these are common areas where marks are lost.
Common Mistakes
Common errors to avoid in your coursework
- Misinterpreting fire resistance ratings, leading to incorrect material selection or inadequate joint detailing.
- Failing to maintain a clean worksite, causing damage to fire-resistant linings through debris or impact.
- Ignoring manufacturer's guidance on fixing centres and perimeters, compromising fire integrity.
- Not accounting for service penetrations and their fire-stopping requirements.
- Misconception: All plasterboard is fire-resistant. Correction: Only specially formulated boards like Fireline are fire-resistant; standard plasterboard will burn through quickly.
- Misconception: The thicker the board, the higher the fire rating. Correction: Fire resistance depends on the whole system, including the number of layers, frame type, and jointing. A single thick board may not achieve the same rating as two thinner layers.
- Misconception: Once installed, fire-resistant walls require no maintenance. Correction: Any damage, such as holes or cracks, must be repaired with appropriate materials to maintain the fire rating.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A fire-resistant wall is to be constructed using metal studs and two layers of 12.5mm Fireline plasterboard on each side. The wall is required to achieve a 60-minute fire resistance. Calculate the total thickness of the plasterboard on one side of the wall and explain why two layers are used.
- 1.Step 1: Identify the number of layers on one side: 2 layers.
- 2.Step 2: Multiply the thickness of one layer by the number of layers: 12.5mm × 2 = 25mm.
- 3.Step 3: State the total thickness: 25mm per side.
- 4.Step 4: Explain the purpose of two layers: to achieve the required fire-resistance rating, as a single layer may only provide 30 minutes. The second layer increases the time it takes for heat to penetrate the wall, providing additional protection.
Question: Describe the correct procedure for installing fire-resistant boards onto a metal stud frame, including the type and spacing of fixings.
- 1.Step 1: Position the first board vertically against the studs, ensuring it is flush with the floor and ceiling.
- 2.Step 2: Use drywall screws of the correct length (e.g., 25mm for 12.5mm board) and fix them at 300mm centres along the studs, starting from the centre and working outwards.
- 3.Step 3: Ensure screws are driven so that the head is just below the surface of the board without breaking the paper.
- 4.Step 4: Stagger the joints between boards to avoid continuous lines, and leave a 3mm gap between boards for jointing.
- 5.Step 5: For fire-resistant walls, use screws that are approved for use with the system and ensure they are not over-tightened.
