Monarfloor Deck 18 - 10 Boards minimum

The Monarfloor Deck 18 is a high-performance acoustic overlay system designed to reduce sound transmission through existing timber floors while maintaining the timber deck. With its flame-retardant construction, compliance with Part E of the Building Regulations, and superior soundproofing capabilities, this floating floor system is ideal for both residential and commercial applications. Each board is robust, measuring 2400mm x 600mm x 26mm, and offers a practical solution for improving acoustic performance without the need for extensive structural changes.

What Are Acoustic Floor Boards?

Acoustic floor boards are specially designed flooring solutions that enhance soundproofing by reducing both airborne and impact noise transmission through floors. These boards are typically constructed from multiple layers, including resilient foam and moisture-resistant materials, to dampen vibrations and prevent sound from passing between floors. They are widely used in renovations, new builds, and conversions to meet stringent building regulations and create quieter living and working spaces.

How Do the Monarfloor Deck 18 Acoustic Floor Boards Work?

The Monarfloor Deck 18 combines advanced materials and engineering to provide excellent acoustic performance:

• 8mm Low Resonance Acoustic Chip (LRAC) Foam: Absorbs impact noise and reduces resonance, preventing sound waves from traveling through the structure.
• 18mm Moisture-Resistant Chipboard: Provides a durable and stable surface for floor finishes.
• Tongue-and-Groove Edges: Ensure a tight fit and simplify installation, enhancing the overall stability of the floating floor system.

When used with 100mm RW3 Acoustic Rockwool and a resilient bar ceiling, the system exceeds the performance standards of Part E of the Building Regulations, effectively isolating sound and improving acoustic comfort.

How Effective are the Monarfloor Deck 18 Floor Boards at Stopping Nuisance Noise?

The Monarfloor Deck 18 delivers superior soundproofing performance:

• Impact Sound Reduction: The LRAC foam layer absorbs vibrations caused by footsteps, furniture movement, and other impact noises.
• Airborne Sound Reduction: The high-density chipboard layer enhances sound insulation, reducing airborne noise such as voices and music.
• Exceeds Building Regulations: When used as part of a complete system, the Deck 18 meets and exceeds the requirements of Approved Document E, ensuring a compliant and effective soundproofing solution.

Where Can the Monarfloor Deck 18 Boards Be Used?

The Deck 18 boards are versatile and suitable for:

• Residential and commercial applications: Ideal for projects where soundproofing is essential.
• Refurbishments and new builds: Designed to upgrade the acoustic performance of existing timber floors or to meet regulations in new constructions.
• Floors with existing timber decking: Specifically intended for use where the timber deck remains, avoiding the need for full floor replacement.
• Floors with stringent fire safety requirements: The flame-retardant properties make it suitable for high-safety applications.

How to Install the Monarfloor Deck 18 Floor Boards?

1. Prepare the Subfloor:
• Ensure the subfloor (timber, chipboard, OSB, or decking ply) is clean, level, and dry.
2. Lay the Boards:
• Use a broken bond pattern for stability, ensuring all tongue-and-groove edges are tightly aligned.
3. Apply Adhesive:
• Bond the tongue-and-groove joints with a high-performance water-based adhesive for added strength.
4. Seal the Perimeter:
• Use acoustic sealant or flanking strips around the edges to prevent sound leaks.
5. Finalise the Installation:
• Allow the adhesive to set before applying the final floor covering.

What Are the Benefits of Using the Monarfloor Deck 18 Acoustic Boards?

• Enhanced Soundproofing: Reduces both impact and airborne noise, creating quieter environments.
• Minimal Structural Alteration: Maintains the existing timber deck and adds only 26mm to the floor height.
• Compliance with Building Regulations: Meets and exceeds Part E standards for sound transmission.
• Flame Retardant: Ensures safety in both residential and commercial applications.
• Durability: Made from moisture-resistant chipboard, ensuring longevity and resilience.
• Easy Installation: The tongue-and-groove design simplifies the installation process, saving time and effort.

How to Tile on Top of an Overlay System?

To tile over the Monarfloor Deck 18, follow these steps:

1. Prepare the Surface:
• Ensure the Deck 18 is level and securely installed.
2. Add Tile Boards or Ply:
• Overlay with proprietary tile boards or plywood to enhance water resistance and stiffness.
3. Use Suitable Tiles:
• Opt for porcelain tiles to ensure durability.
• Keep tile sizes under 600mm x 600mm, with 450mm x 450mm being ideal for better support.
4. Select the Right Adhesives:
• Use adhesives and grouts specifically designed for floating floors. Consult manufacturers for compatibility.
5. Follow Manufacturer Guidelines:
• Adhere to the adhesive and grout manufacturer’s instructions to ensure a long-lasting and stable tiled surface.

We advise you follow the guidance issued by the Tile Association in dealing with floating floors.

With these steps, you can achieve a durable and acoustically effective tiled floor while preserving the benefits of the Monarfloor Deck 18 system.

Instructions for use

Monarfloor Deck 18 platform floor / floating floor (FFT5) system on a timber sub-floor with a resilient bar system:

Diagram Key:

1. Acoustic Flanking Band – reduces impact vibration transmission via party and flanking walls and assists in reducing airborne sound paths

2. 100mm 45kg/m³ insulation

3. 22kg/m² double boarded ceiling on resilient bars perpendicular to joist direction

4. Monarfloor® Deck 18 system on existing timber floor (subject to condition) or new 18mm chipboard deck on 200 x 50mm timber joists

Installation at a glance

• Flank all perimeter with Monarfloor Flanking Band
• Level the sub-floor to the required tolerance
• Lay Monarfloor® Deck 18 platform floor / floating floor (FFT5) system over existing sub-floor in a broken bond pattern, applying Monarfloor® Adhesive to all tongue and groove panel joints
• Install skirting and trim off excess Flanking Band

Tools & equipment required

• 1 litre of Monarfloor® Acoustics Adhesive for every 21.5m2 of deck (approx). Note: Adhesive should be applied in well ventilated rooms
• 1 linear metre of Monarfloor Flanking Band for every 1m2 of flooring
• Utility knife and straight edge
• Joinery hand/power tools
• Check sub-floor is suitably prepared
• Ensure the surfaces are structurally sound, clean and dry
• All internal partitions should be installed and built of the sub-floor
• Kitchens and bathrooms should also be built of the sub-floor (see Monarfloor Generic Kitchen & Bathroom Detail Drawings)
• Ensure the correct mineral wool insulation has been packed tightly between the floor joists

Tiling on top of Monarfloor

We advise you follow the guidance issued by the Tile Association in dealing with floating floors, which is:

• Adhesives and grouts must be suitable for floating floors. There are various systems depending on the individual manufacturers detailing.
• Proprietary tile boards or ply, can be overlaid to provide additional water tightness, and or stiffen the floating floor. These must be bonded.
• Tiles should ideally be porcelain. We do not advise thick heavy tiles such as marble etc as they are more susceptible to fracture.
• Tile format must be kept as small as possible (600 x 600mm max). We would advise 450mm x 450mm.

You should also speak to the adhesive manufacturer that is being used as they all have specific detailing to their own products.

Care of materials

Materials must be kept in a dry storage area at all times.

Working Safely

• Working on any building site can be a hazardous activity. Only suitable persons having appropriate competence, training and physical fitness should be allowed onsite.
• Personal Protective Equipment (PPE) must be worn at all times.
