30mm Acoustic SilentBoard For Solid Walls – Professional Internal Wall Soundproofing Without External Alterations

Transform acoustically poor solid walls into high-performance sound barriers with 30mm Acoustic SilentBoard for Solid Walls – the advanced multi-layer soundproofing panel engineered specifically for internal wall insulation applications. Combining high-density acoustic mass, viscoelastic damping, and resilient decoupling in a slim 30mm profile, SilentBoard delivers exceptional noise reduction for brick, concrete, and stone walls without requiring external work or alterations to building facades.

Why Acoustic Professionals Specify SilentBoard 30mm for Solid Walls

Solid masonry walls – brick, concrete, stone – offer good inherent sound blocking due to their mass. However, they still transmit significant noise, particularly low-frequency sound (traffic, bass music, machinery) and structure-borne vibrations. Traditional solutions like direct-fixed plasterboard provide minimal acoustic improvement, while external insulation is often impractical due to planning restrictions, conservation areas, or building aesthetics.

SilentBoard 30mm solves this challenge by creating an acoustically decoupled internal lining system that significantly improves sound insulation while adding minimal thickness to room dimensions. Whether you're a contractor working on heritage buildings, an architect specifying acoustic upgrades for period properties, or a homeowner seeking peace and quiet without external alterations, SilentBoard 30mm delivers professional-grade soundproofing from the inside.

Advanced Four-Layer Acoustic Technology

SilentBoard 30mm integrates four specialized acoustic layers into a single panel, delivering performance that significantly exceeds standard plasterboard:

Layer 1: High-Density Acoustic Mass Core
The dense core layer adds critical acoustic mass to the wall assembly. Combined with the existing masonry wall mass, this creates a heavy, multi-layer barrier that blocks airborne sound transmission more effectively than either material alone.

Layer 2: Viscoelastic Damping Layer
A specialized viscoelastic polymer layer converts sound energy and vibrations into heat through constrained layer damping. This prevents the panel from resonating and transmitting vibrations from the solid wall into the room – a critical function that standard plasterboard cannot provide.

Layer 3: Resilient Decoupling Layer
The resilient layer provides acoustic isolation between the solid wall and the room-side surface. This decoupling prevents direct vibration transmission through the panel, controlling structure-borne noise that travels through masonry walls.

Layer 4: Protective Surface Layer
A durable surface layer provides structural integrity and a smooth finish ready for decoration, while contributing additional acoustic mass to the overall assembly.

Together, these four layers create a 30mm panel that transforms solid wall acoustic performance while preserving valuable room space.

Superior Acoustic Performance for Solid Walls

  • Significant Sound Reduction: Improves airborne sound insulation (Rw) by 6-12dB compared to bare masonry walls
  • Low-Frequency Control: Particularly effective at controlling bass frequencies (traffic noise, music, machinery) that penetrate masonry
  • Vibration Damping: Viscoelastic layer prevents structure-borne noise transmission through solid walls
  • Wide Frequency Effectiveness: Controls both low-frequency (bass, traffic) and high-frequency (voices, music) noise transmission
  • Thermal Insulation Bonus: Also improves thermal performance, reducing heat loss through solid walls
  • Condensation Control: Can be combined with insulation to prevent cold bridging and condensation
  • Building Regulations Support: Contributes to Part E acoustic requirements and Part L thermal requirements

Installation Methods for Solid Walls

Method 1: Independent Stud Frame System (Recommended for Maximum Performance)

This method creates an acoustically decoupled wall lining that delivers superior soundproofing:

  • Install independent timber or metal stud frame 50-75mm from solid wall (not fixed to wall)
  • Fill cavity between wall and frame with 50-75mm acoustic mineral wool insulation
  • Install SilentBoard 30mm panels to stud frame using drywall screws
  • Seal all perimeter gaps with acoustic sealant
  • Finish as required (skim coat, paint, wallpaper)

Total wall build-out: 80-105mm (50-75mm cavity + 30mm SilentBoard)
Expected acoustic improvement: 8-15dB Rw (significant noise reduction)
Thermal benefit: Substantial U-value improvement with cavity insulation

Method 2: Resilient Clip System (Maximum Acoustic Performance)

For ultimate acoustic isolation, combine SilentBoard with resilient sound isolation clips:

  • Install resilient sound isolation clips to solid wall at 1200mm centers
  • Install furring channels into clips
  • Fill cavity with acoustic mineral wool insulation
  • Install SilentBoard 30mm panels to furring channels
  • Seal perimeters with acoustic sealant

Total wall build-out: 80-100mm
Expected acoustic improvement: 10-18dB Rw (exceptional noise reduction)
Best for: Maximum acoustic performance, low-frequency control, vibration isolation

Method 3: Direct Bonding System (Minimum Space Loss)

For applications where space is critical (consult manufacturer for approved bonding systems):

  • Prepare solid wall surface (clean, dry, level)
  • Apply approved acoustic bonding system to wall or panel
  • Fix SilentBoard 30mm panels directly to wall
  • Seal perimeters with acoustic sealant

Total wall build-out: 30-35mm (minimal space loss)

Installation Guidelines for Optimal Performance

Wall Preparation

  • Surface Condition: Ensure wall is structurally sound, dry, and free from damp or moisture issues
  • Existing Finishes: Remove loose plaster, wallpaper, or unstable finishes
  • Damp Treatment: Address any damp issues before installation – acoustic treatments won't solve moisture problems
  • Level Assessment: Check wall for significant irregularities; independent frame systems accommodate uneven walls better than direct bonding

Independent Frame Installation (Recommended Method)

  • Frame Type: Use 50mm x 50mm or 75mm x 50mm timber studs, or equivalent metal stud frame
  • Frame Position: Install frame 50-75mm from solid wall – frame must NOT touch wall (acoustic decoupling essential)
  • Frame Fixing: Fix frame to floor and ceiling only, not to solid wall
  • Stud Spacing: 400mm or 600mm centers (standard drywall spacing)
  • Cavity Insulation: Fill cavity completely with 50-75mm acoustic mineral wool – essential for acoustic and thermal performance
  • Perimeter Isolation: Maintain 10-15mm gap between frame and adjacent walls; seal with acoustic sealant

SilentBoard Panel Installation

  • Orientation: Install panels vertically or horizontally as required
  • Fixing: Use drywall screws at 300mm centers to studs; ensure screws penetrate studs by minimum 25mm
  • Joint Positioning: Stagger joints for structural integrity
  • Edge Support: Ensure all panel edges are supported by studs or noggins
  • Cutting: Use standard plasterboard cutting tools; score and snap for straight cuts
  • Handling: Panels are heavier than standard plasterboard – use appropriate lifting techniques

Finishing

  • Joint Treatment: Tape and fill joints using standard jointing compound
  • Skim Coat: Apply thin skim coat for smooth finish, or finish joints only for paint/wallpaper
  • Perimeter Sealing: Seal all perimeter gaps with acoustic sealant (not standard decorator's caulk)
  • Service Penetrations: Seal around electrical boxes, switches, and penetrations with acoustic sealant
  • Decoration: Paint, wallpaper, or finish as required – surface accepts all standard decorative treatments

Critical Installation Requirements

Acoustic Decoupling – Essential for Performance:

For independent frame systems, the frame must have zero contact with the solid wall. Any rigid connection creates an acoustic bridge that transmits sound and significantly reduces performance.

  • Maintain 50-75mm gap between frame and solid wall
  • Fix frame to floor and ceiling only, not to wall
  • Fill cavity completely with acoustic mineral wool
  • Seal all perimeter gaps with flexible acoustic sealant

Cavity Insulation – Non-Negotiable:

  • Empty cavities create resonance chambers that can amplify sound
  • Acoustic mineral wool absorbs airborne sound in cavity
  • Also provides essential thermal insulation
  • Use minimum 50mm depth; 75-100mm recommended for maximum performance

Thermal Performance Benefits

In addition to acoustic improvements, SilentBoard 30mm systems provide valuable thermal benefits:

U-Value Improvement:

  • Solid brick wall (uninsulated): ~2.0 W/m²K (poor thermal performance)

  • Use 50mm cavity depth (total build-out: 80mm)
  • Consider direct bonding method for absolute minimum space loss (30-35mm)
  • Prioritize walls where acoustic improvement is most needed

When Space Allows:

  • Use 75-100mm cavity depth for maximum acoustic and thermal performance
  • Consider resilient clip system for ultimate acoustic isolation
  • Treat all external and party walls for comprehensive improvement

Room Dimension Impact:

  • 80mm build-out on two walls of 4m x 4m room: 0.6m² floor area lost (3.8% reduction)
  • Minimal impact on room usability
  • Acoustic and thermal benefits far outweigh small space loss
