The core differentiator of this soundproof composite gypsum board is its multi-layered composite construction: two layers of high-density gypsum board bonded to a sound-dampening polyethylene foam interlayer, which absorbs and dissipates airborne noise vibrations. Unlike standard gypsum boards, which have an STC rating of only 35 dB, this board has an STC rating of 52 dB, providing excellent sound insulation for residential and commercial noise-sensitive spaces. Its tapered edge design allows for seamless joint finishing, reducing installation time by up to 15% compared to square-edge soundproof boards. It also offers fire resistance performance, thanks to the fire retardant coating on its face paper, making it suitable for use in fire-rated soundproof assemblies. The board’s composite construction also provides improved impact resistance compared to single-layer gypsum boards, reducing the risk of surface damage during transportation and on-site construction. It complies with ASTM C1396 and ASTM E90 standards, guaranteeing consistent sound insulation performance for every batch.
This soundproof composite gypsum board has nominal dimensions of 1200mm (width) × 2400mm (length) with a thickness of 19.0mm, a larger thickness than standard gypsum boards that provides enhanced sound insulation performance. Each square meter of the board weighs approximately 15.6 kg, making it sturdy enough to provide reliable sound insulation while remaining manageable for on-site handling. The board features tapered edges on all four sides, with a 5.1mm depth bevel that creates a recessed joint for easy filling and sanding, resulting in a smooth, invisible finished seam. Its face paper is a high-strength kraft stock coated with a fire retardant layer that provides additional fire resistance performance. The core material is a composite structure consisting of two layers of high-density gypsum board bonded to a 3mm thick sound-dampening polyethylene foam interlayer, which absorbs and dissipates airborne noise vibrations. The product complies with ASTM C1396 and ASTM E90 standards, and it has an STC rating of 52 dB, providing excellent sound insulation for residential and commercial noise-sensitive spaces. It also has an Impact Isolation Class of II per ISO 140, providing improved impact noise insulation for multi-family residential spaces. Each pallet contains 12 pieces of the board, secured with plastic wrapping to prevent damage during shipping and handling.
This soundproof composite gypsum board is primarily designed for use in noise-sensitive interior spaces such as home theaters, recording studios, office partitions, multi-family residential walls, hotel guest room walls, and school classrooms. It is ideal for reducing airborne noise transmission between adjacent rooms, such as between a home theater and a living room, or between office cubicles. Professional contractors rely on this board for commercial renovation projects, as it provides reliable sound insulation performance while maintaining ease of installation. DIY homeowners can use this board for home renovation projects, such as building a home theater partition, a home office wall, or a bedroom partition in a multi-family home, as it is easy to cut and install with standard drywall tools. It is compatible with standard drywall fasteners, joint compounds, and finishing tools, making it easy to integrate into any existing construction workflow. It can also be used in conjunction with sound isolation clips and resilient channels to further enhance sound insulation performance for maximum noise reduction.
