Wholesale Acoustic Barriers for Construction Sites

Product Overview

Barriers are supplied as modular panels that can be interconnected to form continuous walls or temporary enclosures. Each panel consists of a core absorptive material faced with a protective outer skin, allowing straightforward handling and rapid deployment. Panels are manufactured to standard widths of 1.2 m and lengths up to 3.0 m, with thickness options ranging from 50 mm to 150 mm depending on performance targets.

Key Technical Characteristics

Material Options

• Mineral wool core – high density, excellent fire resistance, good acoustic absorption across mid‑high frequencies.
• Recycled polyester fiber core – lightweight, moisture resistant, suitable for temporary installations.
• Perforated steel face with absorbent backing – provides impact resistance and a durable outer barrier while maintaining absorption.
• Composite panels with mass‑loaded vinyl layer – increases mass for low‑frequency transmission loss without excessive thickness.

Material selection is driven by the required STC/NRC values, environmental exposure, and handling constraints. For projects with strict fire codes, mineral wool or fire‑retardant treated fabrics are commonly specified. Lightweight polyester cores are preferred when rapid relocation and reduced crane load are priorities.

Typical Applications on Construction Sites

Construction noise often originates from impact tools, concrete pours, and heavy machinery, generating broadband energy that can disturb nearby residences, schools, or hospitals. By erecting a continuous barrier line, the direct path of sound is interrupted, reducing the perceived level by up to 15 dB in the 500 Hz–2 kHz range where human speech intelligibility is most affected. This attenuation helps maintain compliance with local ordinances that frequently limit daytime noise to 70 dB(A) and nighttime levels to 55 dB(A).

In addition to community protection, barriers improve on‑site communication by lowering background noise, which can reduce the risk of misunderstandings and improve safety during coordinated lifts or confined‑space work. The modular nature allows the barrier to be repositioned as work fronts advance, providing a flexible noise control solution throughout the project lifecycle.

Installation Considerations

Panels are typically secured to a steel or timber framework anchored to the ground or to existing structures. Wind loading calculations are essential for exposed sites; bracing members and ground straps are added when the predicted gust pressure exceeds 0.5 kN/m². Overlapping joints are sealed with acoustic tape or compressible strips to prevent flanking paths that could otherwise diminish overall performance by 3‑5 dB.

For temporary installations, quick‑release clamps enable removal without damaging the underlying surface. When the barrier is intended to remain in place for several months, corrosion‑protective coatings on steel frames and UV‑stable outer skins extend service life. All fastening hardware should be inspected periodically for loosening due to vibration.

Quality Control & Testing

Each production lot undergoes dimensional verification (width, length, thickness) within ±2 mm tolerance. Acoustic performance is validated on a representative sample using ISO 10140‑2 for sound transmission loss and ISO 354 for absorption coefficient. Fire performance is assessed via ASTM E84 when a fire‑rating is requested, with results documented in a test report accompanying the shipment.

Visual inspection checks for surface defects, coating uniformity, and proper alignment of facings. Any panel failing to meet the agreed specifications is segregated and either reworked or scrapped. This systematic approach reduces the risk of field performance shortfalls and supports predictable acoustic outcomes for the project.

Customization Options

• Non‑standard panel widths (0.6 m–2.4 m) and lengths up to 4.0 m to suit site layouts.
• Custom surface finishes: powder‑coated colors, printed graphics, or anti‑graffiti coatings.
• Integrated access doors or viewing windows with acoustic seals.
• Additional mass layers for low‑frequency improvement.
• Pre‑drilled mounting holes for rapid bolt‑on installation.

Customization is discussed during the quotation phase, where project drawings, noise target curves, and logistical constraints are reviewed. Engineering drawings are produced and approved before tooling, ensuring that the final product matches the specified performance and fit‑up requirements.

Frequently Asked Questions

Can dimensions be customized to match unique site boundaries?

Yes. Panel width, length, and thickness can be adjusted within manufacturing limits. Provide the required opening sizes and any height restrictions; we will generate a layout drawing for approval before production.

What information is needed to obtain a quotation?

Please share the total barrier length, desired height, expected wind exposure zone, any fire‑rating requirements, and preferred material (mineral wool, polyester, or composite). If you have a noise target (e.g., STC 35), include that as well.

How are the barriers packaged for transport?

Panels are stacked flat on pallets, protected with corner boards and stretch film. For long‑distance shipments, moisture‑barrier wraps and edge protectors are added. Palletized loads are secured with strapping to prevent shifting during transit.

What is the typical lead time for a standard order?

Lead times vary with order size and material availability, but a typical range is 3–4 weeks after drawing approval and receipt of deposit. Expedited options are available upon request for urgent projects.
