Knauf Plank

About Knauf Plank

Knauf Plank Plasterboard is a high-density, 19mm gypsum board engineered to enhance airborne sound insulation in partition walls, ceilings, and floor systems. Soundproofing works on the principle of mass law, which states that heavier materials are more effective at blocking sound waves.
At 19mm thick, Knauf Plank is significantly denser than standard 12.5mm or 15mm plasterboard, making it much better at resisting airborne noise transmission such as conversations, music, and TV sounds.

When used alongside mineral cavity insulation and acoustic sealants, it delivers exceptional noise control, meeting stringent acoustic performance standards across residential, commercial, and industrial applications.

Key Features 

• Specialist Design: Specifically manufactured to enhance acoustic performance in partitions and flooring systems.
• Greater Mass: The additional density increases sound insulation properties.
• Versatile Applications: Suitable for residential, commercial, and office environments where noise control is a priority.
• Industry Compliance: Manufactured to meet rigorous industry standards for safety and performance.

Applications 

• Partition Walls: Enhances acoustic separation between rooms.
• Flooring Systems: Contributes to sound reduction between floors.
• Commercial Fit-Outs: Ideal for offices, meeting rooms, and mixed-use developments.
• Residential Soundproofing: Helps to improve acoustic comfort in homes and apartments.

How It Works in Acoustic Systems

Knauf Plank plays a crucial role in noise reduction, particularly when integrated into multi-layer wall and flooring systems. It provides an additional acoustic mass layer, helping to prevent sound from passing between spaces.

For best results, it is often combined with:

• Acoustic Mineral Wool Insulation - Filling cavities with dense insulation absorbs sound waves and reduces reverberation.
• Acoustic Sealant - Sealing gaps and edges ensures maximum performance by preventing sound leaks.
• Double-Layered Board Systems - Installing multiple layers further improves airborne and impact noise reduction.
• Knauf Acoustic Systems - Designed to work within Knauf’s proprietary partition and floor solutions, ensuring optimal performance and compliance with Building Regulations Part E (Resistance to Sound).

Size & Specifications

The range is available in two specific edge types to accommodate different project requirements:

• 19mm Thickness - Provides enhanced mass for superior sound insulation, particularly in multi-layer drywall systems.
• Tapered Edge (TE) - Features a sloped edge that allows jointing compound to sit flush, ensuring a smooth, even finish with minimal sanding. 
• Square Edge (SE) - Ideal for areas where joints will be concealed with joint compound, tape, trims, or moldings.
• 2400mm x 600mm Dimensions - Compact size allows for easy handling and installation in projects where standard 1200mm wide boards are impractical.

These specifications allow builders, contractors, and architects to tailor their selection to meet acoustic, fire safety, and structural performance needs.
