Temporary sound barrier panels are modular acoustic screens designed to attenuate noise propagation from construction zones, outdoor events, or industrial sites. They consist of sound-absorbing cores faced with durable outer sheets, allowing quick erection and dismantling without permanent foundations. Performance is quantified by sound transmission loss (STC) and weight per unit area, which directly influence installation logistics and acoustic effectiveness.
Key Technical Specifications
| Parameter | Typical Range | Notes |
|---|---|---|
| Overall Height | 1.2 m – 3.0 m | Adjustable in 0.3 m increments via interlocking frames |
| Panel Width | 0.6 m – 1.2 m | Standard module width; custom widths available |
| Core Thickness | 50 mm – 150 mm | Determines absorption coefficient across 125 Hz–4 kHz |
| Surface Density | 8 kg/m² – 20 kg/m² | Influences low‑frequency transmission loss |
| STC Rating | 20 – 30 dB | Measured per ASTM E90; higher values indicate greater sound blockage |
| Wind Load Resistance | Up to 150 km/h | Validated with ANSI/ASCE 7‑16 pressure coefficients |
| Fire Rating | Class A (non‑combustible) or B‑s2,d0 | Based on EN 13501‑1; optional fire‑retardant coatings |
Values above represent typical configurations; actual specifications are tailored to project‑specific acoustic targets, site wind conditions, and regulatory requirements. Engineers should verify STC performance in the field using ISO 140‑5 procedures after installation.
Material Options
- Core: mineral wool (density 80‑150 kg/m³), recycled polyester fiber, or perforated metal‑backed absorbent foam.
- Face sheets: galvanized steel (0.5‑0.8 mm), aluminum (0.7 mm), or UV‑stabilized PVC‑coated fabric.
- Edge protectors: reinforced PVC or rubber profiles to prevent panel‑to‑panel wear during handling.
Selection balances acoustic performance, weight, corrosion resistance, and cost. For coastal environments, aluminum faces with stainless‑steel fasteners reduce corrosion risk; for fire‑sensitive zones, mineral wool cores meet Class A ratings without additives.
Design and Customization
Panels connect via steel pin‑and‑socket couplers that allow angular adjustment up to ±15°, enabling curved layouts around uneven site perimeters. Height adjustment is achieved through telescoping vertical posts with lock‑nuts, providing incremental changes without cutting the panel itself. Connection hardware is galvanized to withstand repeated assembly cycles.
Optional features include integrated cable conduits for temporary lighting, transparent polycarbonate strips for visual monitoring, and removable acoustic blankets for enhanced mid‑frequency absorption. All customizations are documented in shop drawings that reference ISO 9001‑controlled revision levels.
Applications and Performance Benefits
Construction sites benefit from reduced noise spillover to nearby residential zones, helping maintain compliance with local ordinances that often limit daytime sound levels to 55 dB(A). Event organizers use the panels to isolate stage areas, lowering reverberation and improving intelligibility for audiences without permanent structural changes.
In industrial settings, temporary barriers contain compressor or generator noise during maintenance shutdowns, protecting workers in adjacent zones from exposure above 85 dB(A) thresholds. The modular nature allows relocation as work fronts shift, minimizing redundant material handling.
Quality Control and Testing
Each production lot undergoes core density verification using a calibrated gamma densitometer, with acceptance criteria ±5 % of target. Face sheet thickness is measured via ultrasonic gauging, and coating adhesion is tested per ASTM D3359. Finished panels are subjected to a randomized STC test in a reverberation chamber to confirm batch consistency.
Documentation includes material certificates, test reports, and a traceability label affixed to each panel, referencing the production order number. Non‑conforming items are segregated and reworked before shipping, ensuring that only panels meeting the specified acoustic and mechanical criteria reach the customer.
Packaging and Logistics
Panels are stacked face‑to‑face with interleaving corrugated cardboard sheets to prevent surface abrasion, then secured with PET straps on wooden pallets sized for standard 20‑foot container loading. Each pallet carries a maximum load of 1.5 t, calculated based on panel weight and stacking height limits.
Corner protectors and stretch film wrap provide additional weather resistance during transit. For overseas shipments, fumigated pallets and ISPM‑15 compliance marks are applied as required. Packing lists detail panel count, dimensions, and total gross weight to facilitate customs clearance.
Lead Time and Sampling
Standard production lead time ranges from 18 to 25 working days after receipt of approved drawings and deposit, depending on order volume and material availability. Expedited schedules can be arranged for urgent projects, subject to capacity confirmation.
Sample panels (typically one full‑size unit) are available upon request, with shipping costs borne by the requester. Samples allow on‑site acoustic validation and interface verification before committing to full‑scale production.
Frequently Asked Questions
- Can dimensions be customized? Yes, panel height, width, and core thickness are adjustable in increments specified in the technical data sheet; custom lengths require new tooling.
- What information is required before quotation? Required inputs include desired acoustic performance (STC or transmission loss), site dimensions, wind load criteria, fire rating preference, and delivery schedule.
- How is quality inspected? Each lot undergoes dimensional checks, material density verification, and random STC testing per ISO 10140‑2; inspection reports accompany shipments.
- What packaging methods are available? Standard packaging uses palletized stacks with cardboard interleaving and PET straps; optional crate packing is offered for high‑value or fragile configurations.
- How are export shipments protected? Pallets are fumigated, wrapped in stretch film, and fitted with corner boards; all meet ISPM‑15 standards for international transport.
