Straight Bar Grille Sound-Absorbing Panel

Key Advantages

• Straight bar three-dimensional grille: Longitudinal straight bar regular arrangement – enhances wall texture and sound diffusion surface area
• Sound absorption: Reduces indoor echo and reverberation time – lowers ambient noise
• Two thickness options: 2.1cm and 1.8cm – accommodate different acoustic requirements and installation spaces
• Eco-friendly substrate: Complies with indoor decoration material environmental standards
• Moisture-resistant and deformation-resistant: Low water absorption – high structural stability
• Easy installation: Adhesive, dry-hanging, or with furring channel systems
• High adaptability: Suitable for both walls and ceilings – adaptable to various interior spaces

FAQ and Precautions

Q: What is the sound absorption principle of the straight bar grille sound-absorbing panel?
A: The grille structure causes sound to undergo diffuse reflection and multiple refractions between relief surfaces, converting some sound energy into heat. Additionally, micropores within the substrate absorb specific sound frequencies. Specific sound absorption coefficients depend on thickness, grille spacing, and substrate density.

Q: How to choose between 2.1cm and 1.8cm thickness?
A: The 2.1cm thickness provides better sound absorption, especially for mid-to-low frequencies, suitable for spaces with higher acoustic requirements (e.G., Meeting rooms, media rooms). The 1.8cm thickness is slightly lighter, suitable for applications with moderate acoustic requirements or where installation convenience or space thickness constraints are prioritized.

Q: What are the suitable applications for the 28cm width?
A: The 28cm width is a medium specification, offering balanced coverage per panel for easy handling and installation. It is suitable for continuous large-area wall installation as well as decorative bands or mixed-material applications.

Q: Does the surface trap dust easily?
A: The straight bar grille has longitudinal groove channels. Clean with a vacuum cleaner using a soft brush attachment along the grille direction, or wipe groove surfaces with a dry cloth. Regular cleaning maintains cleanliness.

Q: Can it be used in humid environments such as bathrooms?
A: The product offers moisture resistance, suitable for bathroom dry area wall decoration. For areas near shower zones, maintain distance from direct water exposure. Moisture resistance varies by substrate type – refer to product test reports.

Precautions

• Check substrate flatness, dryness, and cleanliness before installation. Recommended deviation ≤3mm over 2 meters.
• Use a fine-tooth saw blade for cutting to maintain straight edges. For multi-panel assembly, pre-arrange layout to ensure consistent grille direction and even joints.
• Use neutral eco-friendly adhesives (for adhesive installation) or appropriate fasteners (for furring channel installation). Avoid solvent-based adhesives containing toluene or xylene.
• Clean with a soft cloth, soft brush, or vacuum cleaner with a soft brush attachment. Avoid excessive water soaking. Avoid steel wool, stiff brushes, abrasive cleaners, or strong acids/alkalis.
• Store panels flat with stack height not exceeding one meter. Avoid heavy pressure that may deform grilles. Raised grille portions are sensitive to heavy pressure.
• Protect panel surfaces and edges during transport. Avoid impact that may damage grille ends or scratch surfaces.
• Use a level during installation to ensure panels are horizontally or vertically aligned. Maintain uniform gaps when assembling multiple panels.
• Avoid using transparent adhesive tape for temporary fixing on the surface, as residue may damage the surface finish.
• After panel installation, when performing other work on the wall, protect the panel surface from contamination or scratches.
• Sound absorption performance is improved when an air cavity is maintained between the panel and the wall (recommended cavity depth 10-20mm). Consult the manufacturer for specific installation methods.
• For ceiling applications, ensure furring channel spacing is appropriate (recommended ≤400mm) and use appropriate fasteners.
