Introduction to Acústica XXI Innovation

Castelhano & Ferreira, SA introduces a new line of acoustic products developed through R&D, featuring innovative shapes and materials primarily using foam for high-frequency sound absorption. These products are designed for critical acoustic environments such as home theaters, studios, offices, auditoriums, and entrance halls. Finishes include natural foam (light grey, anthracite) and velvet-effect in multiple colors.

Product Range and Specifications

• Wave Foam: MDF boards (16mm) with vertical foam strips (12mm), size 1200x600x106mm.
• CF MLS: Foam on grooved MDF boards (3mm), size 600x600x53mm.
• Cube Foam: Machined foam boards with MDF support, size 595x595mm.
• Scatter Panels: Diffuser/absorber panels with 30mm Valchromat rulers and aluminum waveguides, size 1798x195mm.
• Vime AC: Machined Valchromat board with grooves, size 2480x900mm.
• CF Studio: Foam or MDF boards with acoustic screen and velvet finish, size 595x595x52mm.

Acoustic Importance and Applications

Acoustic comfort is crucial in spaces like auditoriums, sports halls, and churches. The company ensures solutions meet functional and aesthetic needs, complying with legal standards (Decree-Law No. 96/2008) that regulate reverberation time and sound absorption across various building types.

System Features and Versatility

• Multiple perforation patterns and finishes adaptable to walls, ceilings, partitions, doors, and cabinets.
• Consistent visual appearance with hidden joints (CFRF, Linear Acoustics, FAST systems).
• Flexible assembly systems tailored to different models and installation contexts.

Perforation Types and Acoustic Performance

• Round holes (5-20mm diameter) with perforation rates from ~4.6% to ~29%.
• Square holes (18x18mm to 31x31mm) with rates ~28%-32%.
• Slots/grooves with rates ~10%-18%.
• Specialized grooving patterns (CFRF, FAST, Linear Acoustics) with detailed perforation data.

Combining visible and hidden perforation models enhances acoustic performance.

Technical Characteristics

• Panels made from fire-retardant MDF (B-s2-d0 per UNE-EN 13501-1) with laminate or veneer coatings; Valchromat® options with fire-retardant varnish.
• Acoustic screen with fire-retardant properties on panel backs.
• Standard ceiling panels: 595x595mm, 12mm thick (exceptions apply).
• Installation limited to environments with humidity below 70%; panels require 2-3 days acclimation on-site.

Acoustic Performance Data

Graphs show "Plus" versions outperform "Standard" models in absorption coefficients across frequencies, especially when combined with mineral wool backing (4cm thick, 40kg/m3).

Assembly and Installation

• Ceiling panels installed on standard profiles with options for semi-hidden or fully hidden structures; ceilings are fully removable.
• Hidden structure ceilings require specific recessed lighting (595x595mm).
• Wall panels use hidden structures with removable access.

Finishes and Colors

• Natural foam colors: light grey, grey, black, chocolate.
• Velvet-effect finishes: wide palette including red, yellow, violet, orange, blue, green.
• Valchromat® colors exclude orange and violet in 12mm thickness.
• Laminate, veneer, and lacquer finishes available on request.

Summary of Key Benefits

• High-performance acoustic absorption and diffusion for critical listening environments.
• Compliance with legal acoustic standards for diverse building types.
• Versatile application on multiple surfaces with customizable aesthetics.
• Use of fire-retardant materials ensuring safety compliance.
• Comprehensive technical support and acoustic consultancy services.
