Product Types & Edge Profiles

Core Construction & Edge Configurations
Resin-Hardened Edge (Standard): Chemical resin impregnation reinforces the fiberglass perimeter, preventing edge deformation during field handling and concealed clip installation.

Aluminum Frame Inner Core: An extruded aluminum sub-frame is embedded within the core to provide rigid structural support for large-format panels (>= 1200 mm x 2400 mm) or high-impact areas.

Wrapped Engineered Timber Edge: Internal MDF or hardwood border strips embedded for high-impact commercial corridors requiring perimeter screw-fixing or specialty trim integration.

Edge Profile Options
Square Edge (90°): Clean butt-joint layouts with minimal visible panel-to-panel seam gap.

Beveled Edge (45° / 15°): 8 mm to 15 mm chamfered edges that add visual depth and mask subtle substrate irregularities.

Radiused / Rounded Edge: Smooth 10 mm radius profile designed for high-touch interior environments.

Customization & Installation Systems

Customization Options
Fabric Selection: Choose from acoustically transparent woven polyester, recycled wool blends, or client-supplied C.O.M. (Customer's Own Material) after acoustical permeability verification.

Custom Shapes: Precision CNC router cutting allows non-rectangular geometric layouts, including hexagons, parallelograms, and segmented wall patterns.

Digital Artwork Printing: Custom high-resolution dye-sublimation printing on acoustically transparent fabric facings without obstructing sound wave penetration into the core.

Installation Systems
Impaling Clips & Construction Adhesive
Lay out panel positioning lines on the wall substrate.
Fasten galvanized steel impaling clips into drywall or masonry studs using anchor screws.
Apply construction-grade polyurethane adhesive dots on the back of the fiberglass panel.
Press the panel firmly onto the impaling clip prongs until flush with adjacent panels.

Rotofast Anchor & Z-Clip Systems
Screw helical Rotofast anchors directly into the back core of the panel.
Mount interlocking aluminum Z-clips on the wall surface.
Hang panels by engaging panel-mounted bracket clips onto the wall-mounted Z-track for a concealed, removable attachment.

pTesting & Quality Compliance

Quality assurance controls cover raw material intake through final panel assembly. Every manufacturing batch undergoes inspection to ensure full project compliance.

01/

Flame Spread & Smoke Density: Fabrics and fiberglass cores are batch-tested to verify ASTM E84 (FS <= 25, SD <= 450) and EN 13501-1 certification.

02/

Acoustical Permeability: Fabric facings undergo air permeability testing (ASTM D737) to confirm sound energy passes into the glasswool core without surface reflection.

03/

Adhesive Bonding Integrity: Thermosetting solvent-free hot melt adhesives undergo environmental chamber testing (-20°C to +70°C) to prevent fabric delamination, wrinkling, or off-gassing over time.

04/

Batch Color Consistency: Spectrophotometer color-matching limits dye-lot variation to Delta E < 0.8 across distinct production runs.

FAQ

Q: Can we supply our own fabric (C.O.M.) for custom panel wrapping?

A: Yes. We accept Customer's Own Material (C.O.M.) subject to prior acoustic permeability and stretch testing. Samples must pass our air flow resistance check (< 500 Pa·s/m) to ensure unhindered sound transmission into the acoustic core.

Q: What is the difference between 25 mm (1") and 50 mm (2") panels in acoustic performance?

A: 25 mm panels efficiently absorb mid-to-high frequency sound (500 Hz - 4000 Hz) with an NRC of ~0.85, ideal for standard speech control. 50 mm panels extend absorption down into the lower frequency spectrum (125 Hz - 250 Hz) with an NRC of 1.00+, necessary for music studios, auditoriums, and mechanical noise reduction.

Q: How do your panels meet local commercial fire codes in North America and Europe?

A: Both our glasswool cores and woven fabrics are individually and composite-tested. We supply full test reports for ASTM E84 Class A (USA/Canada) and EN 13501-1 Class B-s1, d0 (Europe) issued by accredited third-party laboratories (SGS / Intertek).

Q: What measures prevent fabric sagging or delamination over time?

A: We apply high-tack, solvent-free hot melt spray adhesive under automatic tension control. The fabric is folded tight around resin-hardened edges and back-stapled under calculated tension to prevent thermal-humidity sagging in non-climate-controlled spaces.

Q: What is the typical lead time for a project order of 2,000 square meters?

A: Standard manufacturing lead time is 12 to 18 working days following CAD drawing sign-off and color match confirmation. Urgent batch shipments can be staggered in containers according to the jobsite installation schedule.

Q: How do you handle dimensional tolerances for custom ceiling/wall grid patterns?

A: All core cutting and resin-edge profiling are performed on multi-axis CNC routing tables. Dimensional tolerances are held within +/- 1.0 mm, guaranteeing tight butt joints and accurate alignment across large modular wall matrices.
