Import Adhesive Felt Soundproof Underlay For Sale — Buy in Bulk from Supplier in China

Changshu Keytex Industrial’s adhesive felt soundproof underlay is a multi-layer composite designed for flooring protection and acoustic dampening in construction and renovation projects. The material features a white PE membrane top layer, a nonwoven fleece middle layer, and a self-adhesive coating at the bottom, with a total thickness of approximately 1.7 mm. Each roll measures 100 cm in width and 25 meters in length, with a weight of 160 g/m² (±5%), providing a dense yet flexible barrier against liquids and impact noise.

The underlay is engineered to be non-slip on stairs, eliminating the need for additional tape, and is impermeable to protect concrete and other substrates from moisture and spills. Its tear-resistant construction ensures durability on active building sites, while the self-adhesive backing allows for quick installation and removal without leaving residues. Standard industry specifications for such underlays include sound reduction indices (SRI) of 20-30 dB for impact noise, though exact values should be confirmed with the supplier.

Primary applications include temporary protection for floors and stairs during construction, as well as permanent underlayment for soundproofing in residential and commercial spaces. The material is particularly effective in high-traffic areas where moisture resistance and ease of cleaning are priorities. Originating from Changshu, China, the underlay is suitable for global export, with logistics tailored to building material distributors and contractors.
