Acoustic Underlayment with Moisture Barrier

HouseDress Jinbo® Acoustic Underlayment with Moisture Barrier is a honeycomb polymer elastic cushioning material designed for installation beneath solid wood flooring, laminate flooring and SPC stone-plastic flooring. It forms one component of floating floor assemblies and sits between the finished flooring layer and cement subfloor.

This acoustic underlayment with moisture barrier, manufactured by Xiashi Packing Co., Ltd., is engineered for elastic cushioning under flooring systems. It is widely specified for prefabricated residential buildings, apartments, hotels and light-gauge steel construction projects, serving as an auxiliary component within finished flooring assemblies.

Acoustic Function: Honeycomb Structure Design

Conventional flat underlay relies on the inherent elasticity of raw foam for cushioning. HouseDress Jinbo® acoustic underlayment adopts a three-dimensional honeycomb cavity structure as its core design.

- Impact cushioning design: When impact loads such as foot traffic or furniture movement act on the floor surface, the raised honeycomb structure undergoes elastic deformation. Its impact sound performance should be evaluated as part of the complete floor assembly.

- Cavity decoupling layout: The honeycomb layout creates discrete internal cavities intended to interrupt continuous solid vibration pathways. Actual performance relies on the full flooring system configuration.

- Distributed load support: Raised honeycomb protrusions provide point support for the floor covering, helping spread applied loads and reduce the risk of localized concentrated stress on flooring materials.

- Integrated moisture barrier layer: The built-in barrier layer is designed to slow upward moisture migration from the concrete subfloor.

Application Scenarios

- High-end finished apartments: Flooring cushioning for multi-storey residential projects

- Hotel and guest rooms: Flooring decoupling layer for guest room assemblies

- Light-gauge steel prefabricated buildings: Cushion layer for structural floor slabs

- Commercial office spaces: Under-floor cushioning for SPC stone-plastic flooring installations

- Renovation of existing residential buildings: Compatible with dry-lay installation over intact concrete subfloors without major slab modification

- Kindergartens and gym facilities: Cushioning under areas with frequent foot movement and equipment impact

Environmental Protection and Safety Performance

Jinbo moisture barrier underlayment are manufactured using modified polymer raw materials, with no harmful additives introduced during production. They come with environmental compliance test reports and asbestos-free certifications, meeting the green building material audit requirements for domestic markets as well as export projects to Australia and Europe. The product is odorless, and no prolonged ventilation is required after installation to eliminate odors, making it ideal for residential, hotel, and kindergarten spaces where stringent indoor air quality standards are enforced. The material exhibits excellent chemical stability, resists mold growth, and in humid underground or low-level building environments, effectively inhibits mold development, thereby protecting the flooring system.

Why Choose HouseDress Jinbo

Many commonly specified underlay materials include flat XPE, EPE foam and non-woven options. HouseDress Jinbo acoustic underlayment with moisture barrier features a 3D honeycomb cavity layout.

The design combines elastic honeycomb support and an integrated moisture barrier. It removes the requirement for a separate PE membrane under appropriate site conditions and streamlines site work. Rolls are easy to cut on site, and the textured honeycomb surface helps reduce shifting during flooring placement. The substrate should still meet the flatness requirements specified by the flooring manufacturer.

FAQs

Q1: What types of noise does this acoustic underlayment with moisture barrier address?

A: It targets floor-borne impact vibration, such as vibration generated by walking, furniture movement and running. It is not designed as the primary solution for airborne noise including speech and television sound.

Q2: Can it be laid directly over concrete?

A: Yes, provided the subfloor is sound, dry, free of sharp projections, and any voids or defects have been repaired prior to installation.

Q3: Is an additional separate moisture-proof membrane required?

A: The underlayment includes an integrated moisture barrier. Whether an additional PE moisture membrane is required depends on subfloor moisture conditions, flooring manufacturer instructions and applicable installation requirements.

Q4： Should the underlayment be fully bonded with adhesive?

A: Full adhesive bonding across the sheet is not recommended. Continuous bonding can create acoustic bridges and compromise vibration decoupling performance. Only tape sealing at seams is advised.

Q5: Can thickness and width be customized? What is the MOQ?

A: Custom thickness and width are supported. Standard-size rolls are available. Please contact our sales team for MOQ and lead-time details.
