HIF-A Series High Polymer Sound Insulation Felt | Professional Acoustic Solution

Product Overview

WINEGO SOUND HIF-A Series represents the next generation of eco-friendly acoustic barriers, engineered for superior noise reduction in architectural and industrial applications. Manufactured from 100% virgin eco-polymer using physical high-pressure compression technology—completely free from chemical adhesives—this advanced material effectively dissipates sound energy through high-density molecular structure.

Leveraging the Mass Law and Damping Vibration Reduction principles, combined with our proprietary cavity resonance suppression technology, the HIF-A series blocks broadband noise transmission from 125Hz to 25KHz. When laminated with gypsum boards, calcium silicate panels, or wooden substrates, it creates a triple acoustic barrier (absorption-isolation-damping) that boosts overall sound insulation by 15-30dB.

Standard Installation Guide

5-Step Installation Method (Wall Application)

Step 1: Substrate Preparation

• Clean wall surface of dust and debris

• Install light steel or wooden studs at ≤600mm intervals

Step 2: Absorption Layer Installation

• Fill stud cavities with glass wool/rock wool (density ≥32kg/m³)

• Ensure complete filling without gaps for mid-high frequency absorption

Step 3: Felt Application

• Unroll HIF-A horizontally with 10mm overlap at seams

• Use "cross-cut" method for pipe penetrations (see diagram)

Step 4: Mechanical Fastening

• Secure with staple gun or self-tapping screws at ≤300mm intervals

• 45° miter cuts at corners to avoid sound bridges

Step 5: Sealing Treatment

• Apply SG-1 Acoustic Damping Sealant at all seams and edges

• Use specialized acoustic tape to seal panel joints for airtightness

⚠️ Pro Tip: Install facing panels (gypsum board) with staggered seams relative to the felt layer to create a "mass-spring-mass" acoustic isolation system.

What Our Global Clients Say

⭐⭐⭐⭐⭐ Mark Thompson, Acoustic Consultant | London, UK "We specified HIF-A20 for a professional recording studio project in Soho. Paired with double-layer gypsum board, we achieved 52dB sound insulation—exceeding the client's expectations. The zero-odor characteristic was crucial for the artist who has chemical sensitivities. Delivered on time to our London warehouse."

⭐⭐⭐⭐⭐ Sarah Chen, Project Director | Marina Bay Hotel Group | Singapore "After testing multiple acoustic felts, WINEGO's HIF-A was the only product that passed our fire Class A requirements while meeting acoustic design specs. The 20-meter roll length reduced on-site seams by 40%, improving installation efficiency significantly. We've now standardized on this for all our luxury hotel renovations across Southeast Asia."

⭐⭐⭐⭐⭐ Hans Müller, Home Cinema Specialist | Munich, Germany "Installed HIF-A30 in a basement home theater project with floating floor construction. The client reported zero bass transmission to the living room above—even with the subwoofer at full volume. The material's flexibility made wrapping HVAC ducts incredibly easy without heating. My installation team loves working with it."

⭐⭐⭐⭐⭐ Jennifer Walsh, School District Facilities Manager | Toronto, Canada "We used HIF-A10 for music room partitions in three elementary schools. Previously, we had constant complaints from neighboring classrooms. Now, with 12 practice rooms operating simultaneously, the hallway remains remarkably quiet. The cost-performance ratio is unbeatable for educational institutions."

⭐⭐⭐⭐⭐ Ahmed Hassan, Commercial Contractor | Dubai, UAE "Fire safety is non-negotiable in Dubai's commercial buildings. HIF-A's ASTM E-84 Class A certification made permitting smooth and fast. Used it for a corporate headquarters VIP meeting rooms project—client is extremely satisfied with the speech privacy levels achieved."
