ROCKFLOOR - Acoustic Installation Guide

Essential Tools:

• Measuring tape and ruler
• Utility knife with extra blades
• Straightedge or T-square
• Safety glasses and work gloves
• Adhesive (appropriate ROCKFLOOR adhesive)
• Putty knife or trowel for adhesive application
• Sealant gun for joint sealing
• Roller for smoothing down materials
• Saw for cutting around obstacles
• Dust mask for cutting operations

ROCKFLOOR Components:

Your specific installation may require some or all of these components:

• ROCKFLOOR acoustic underlay
• ROCKFLOOR isolation strips
• ROCKFLOOR acoustic sealant
• ROCKFLOOR transition strips
• ROCKFLOOR specialized fasteners (if required)

Surface Assessment

Examine the subfloor for levelness and structural integrity. Repair any damaged areas before proceeding. The surface should be clean, dry and free of debris, dust, oil, or other contaminants that might affect adhesion.

Acclimate Materials

Allow ROCKFLOOR materials to acclimate to the room temperature for at least 48 hours before installation. This prevents expansion or contraction after installation. Ideal conditions are between 18-24C with relative humidity of 45-65%.

Obstacle Preparation

Install isolation strips around the perimeter of the room and around any fixed obstacles such as pipes, built-in cabinets, or architectural columns. Isolate the ROCKFLOOR system from walls to prevent flanking transmission of sound vibrations.

Step 1: Base Layer Installation

Begin by applying ROCKFLOOR adhesive according to manufacturer instructions. Use the recommended trowel size to achieve proper ridges for optimal adhesion. Install the base layer sheets with staggered joints, similar to brick laying pattern. Ensure seams are tight but not overlapping.

Use a roller to firmly press down the material, removing any air pockets and ensuring complete contact with the adhesive. Work from the center outward to push air toward the edges.

Step 2: Cutting and Fitting

Measure carefully before cutting. Use a sharp utility knife and straightedge to make clean cuts. Slightly undercut the material to allow for expansion. For complex shapes, create a cardboard template first, then transfer the pattern to the ROCKFLOOR material.

When cutting around obstacles, leave a small gap (typically 3-5mm) to fill with ROCKFLOOR acoustic sealant.

Step 3: Sealing Joints

Apply ROCKFLOOR acoustic sealant to all seams and joints. Use a sealant gun with a cut tip appropriate for your joint widths. Tool the sealant with your finger or a specialized joint finishing tool for a smooth, continuous seal.

Pay special attention to wall junctions, door thresholds, and transitions to other flooring types. Proper sealing prevents acoustic bridges that would compromise sound reduction performance.

Step 4: Mid-Layer Installation (If Applicable)

For enhanced acoustic performance, install the middle layer of ROCKFLOOR system following the same procedure as the base layer. Offset the joints from the base layer to create a stronger assembly. This layer adds mass and decouples the finished floor from the subfloor, significantly improving impact sound insulation.

Step 5: Top Layer Installation

Install the final layer according to your ROCKFLOOR system specifications. This may be a specialized acoustic membrane or prepared underlayment ready for your finished flooring. Follow the same offset pattern for joints to maintain system integrity.

Suitable floor coverings can include carpet, engineered wood, laminates, or certain types of vinyl (check manufacturer recommendations). Allow proper curing time before foot traffic.

Step 6: Transition Installations

Install ROCKFLOOR transition strips at doorways and where the acoustic system meets different flooring materials. These specialized transitions maintain acoustic isolation while providing a finished appearance and functional connection between surfaces.

Air Bubbles

If you notice air pockets after installation, use a needle to puncture the bubble and press the material down. Apply a small amount of adhesive if needed, then use a roller to re-establish proper contact.

Uneven Joints

Minor height differences between sheets can be smoothed with additional ROCKFLOOR material or specialized leveling compounds designed for acoustic systems. For significant issues, the affected area may need to be replaced.

Sealant Failures

If sealant cracks or loses adhesion, remove the failed material, clean the area, and reapply fresh sealant. Ensure the surface is clean and dry before reapplication.

Impact Insulation: Reduction of footfall noise by 20-32 decibels depending on configuration.

Airborne Sound Isolation: Improvement of Sound Transmission Class (STC) by 15-35 points.

Room Acoustics: Reduction of reverberation time by 20-50%, creating clearer sound environments.

Floating Installation Method

For maximum sound isolation, create a completely floating floor system by installing ROCKFLOOR over sleepers or joists, completely decoupling the finished floor from the building structure. This method provides the highest level of sound isolation but is more complex to install.

Multi-Density Layering

Incorporating layers of different density materials within your ROCKFLOOR system can address specific frequency ranges of unwanted sound. This technique is particularly effective for music practice rooms or home theaters where specific acoustic challenges exist.

Resilient Channel Integration

Combining ROCKFLOOR flooring systems with resilient channels on walls creates a complete acoustic isolation envelope. This approach is particularly beneficial for apartments condos or spaces with shared walls.

Can ROCKFLOOR be installed over existing flooring?

In many cases, yes. ROCKFLOOR can be installed over existing hard flooring if the surface is level, stable, and properly prepared. Carpet must always be removed before installation.

Is ROCKFLOOR suitable for bathrooms?

ROCKFLOOR systems can be used in bathrooms with proper water-resistant materials and careful sealing of all joints and transitions. Specialized waterproof versions are available for wet areas.

How thick is the ROCKFLOOR system?

Total thickness depends on the specific configuration but typically ranges from 12mm for basic residential applications to 50mm for commercial or high-performance installations. Consider your floor height requirements when planning.

Can finished flooring be removed and reinstalled later?

While the finished surface flooring can potentially be removed and replaced, the ROCKFLOOR acoustic system underneath is not designed for removal and reinstallation. Damages to the acoustic layers would likely require replacement.

Does ROCKFLOOR work with radiant floor heating?

Special heat-resistant ROCKFLOOR systems are available for use with radiant floor heating. These products are designed to maintain acoustic performance while allowing optimal heat transfer. Standard ROCKFLOOR materials should not be used with radiant heating systems.
