Sandrock Acoustic Panel for Architectural Ceiling Systems
Ecowol Sandrock Acoustic Panel is a decorative sound-absorbing panel designed for ceiling applications where acoustic performance and architectural appearance are both important. Made using processed inorganic particles, including natural sand particles, the product creates a distinctive surface texture while providing a material structure intended to help absorb sound.
In many commercial and public interiors, ceilings contribute significantly to the room’s acoustic environment. Large, hard surfaces can reflect sound back into occupied areas, leading to excessive reverberation. A properly selected acoustic ceiling system can help manage these reflections and support a more comfortable environment for conversations, learning, meetings, and other activities.
The Ecowol catalogue describes Sandrock Acoustic Panel as a particle-based sound-absorbing material. Natural white quartz stone is identified as the main raw material in the product description, with particles crushed, screened, selected, and dyed after high-temperature processing. The resulting surface offers a decorative texture that can be integrated into interior ceiling design.
Decorative Texture and Acoustic Function
The Sandrock Acoustic Panel is intended to combine the visual quality of a decorative ceiling with the function of sound absorption. Rather than treating acoustic materials as a separate addition, the product can be considered as part of the overall architectural finish.
For hotel interiors, the panel may be evaluated for selected public or shared spaces where the ceiling design must complement the surrounding materials. In offices, it can be considered for suitable common areas, meeting environments, and other spaces that require acoustic treatment. Educational and public buildings may also evaluate the product according to the room’s Sandrock Acoustic Panel objectives and ceiling requirements.
The final selection should take into account the architectural concept, ceiling height, existing construction, maintenance needs, and acoustic performance requirements. A decorative finish alone does not determine how much sound will be absorbed by the complete ceiling system.
Sandrock Acoustic Panel Material and Surface Structure
The catalogue explains that inorganic particles are processed and bound together to create interconnected small openings within the material. When sound reaches the surface, some energy may be reflected while some enters the material’s porous structure, where part of the sound energy is dissipated.
This construction is intended to support sound absorption and reduce some of the sound energy reflected into a room. The final result depends on the product configuration, the supporting structure, installation details, and the acoustic characteristics of the space.
The catalogue states that the sound absorption coefficient can generally reach an NRC range of 0.7–0.9, depending on the configuration. This should not be interpreted as a guaranteed value for every installation. The project team should request the relevant test data for the selected product and ceiling arrangement.
Product Dimensions and Weight
The catalogue lists two standard formats: 600 × 600 × 6 mm and 600 × 1200 × 8 mm. The corresponding weights are listed as 3.5 kg per sheet for the 6 mm panel and 8.5 kg per sheet for the 8 mm panel.
These details are useful for preliminary planning, but the selected panel size and weight should be verified before finalizing the ceiling design. The supporting framework and installation system must be suitable for the specified product.
The catalogue states that the installation method is similar to that used for plasterboard ceilings and recommends the product for ceiling applications. The contractor should follow the approved installation details and supplier instructions, particularly where the project includes service openings, lighting, or other ceiling components.
Applications in Hotels, Offices, and Educational Buildings
In hospitality environments, ceiling finishes help establish the overall character of a room. Sandrock Acoustic Panel can be considered where the design calls for a textured decorative surface with sound-absorbing functionality.
In commercial offices, acoustic ceiling treatment may help address reflections in shared spaces and meeting environments. For schools and other educational buildings, Sandrock Acoustic Panel requirements should be assessed according to room size, occupancy, speech activities, and existing finishes.
Large auditoriums, multipurpose spaces, and public interiors may require detailed acoustic planning. The product should be assessed alongside other potential treatments rather than being expected to solve every acoustic issue independently.
Fire, Environmental, and Durability Considerations
The catalogue describes the panel as having moisture, frost, acid, alkali, salt-spray, corrosion, and aging resistance. It also lists fire-related classifications of A2, S1, and d0, along with a product strength value of 0.7 MPa. These statements should be verified against the documentation for the exact product and the requirements applicable to the project.
For buildings with strict fire or environmental specifications, the project team should obtain the relevant technical reports and confirm that the selected product configuration meets the requirements. Environmental claims should likewise be supported by appropriate documentation.
Ecowol Sandrock Acoustic Panel offers a decorative ceiling option for projects seeking a textured inorganic particle finish with sound-absorbing functionality. With appropriate product verification, ceiling coordination, and acoustic planning, it can be considered for a range of commercial and public interiors.
