ASLONG DualShield — Dual-Layer Sound & Heat Insulation Mat

ASLONG DualShield is a purpose-built dual-layer sound & heat insulation mat that combines two complementary layers into a single composite solution: a vibration-damping layer that reduces structure-borne noise and a thermal barrier layer that limits heat transfer. The two layers work together to block airborne sound, absorb impact and vibration energy, and slow thermal conduction—delivering simultaneous acoustic comfort and improved thermal performance for vehicles, buildings, home theaters, industrial enclosures and more. ASLONG developed DualShield drawing on our acoustic materials expertise (Welllink Guangdong New Material Co., Ltd., founded 2000) and a production base of more than 10,000 m².

Performance depends on product thickness, weight, substrate and installation method, but customers typically see measurable reductions in both airborne and structure-borne noise and noticeable reductions in heat transfer after installing a dual-layer sound & heat insulation mat. ASLONG supplies technical datasheets and can provide third‑party test reports or customized lab testing (ISO/ASTM/EN standards on request) so you can evaluate dB reduction, STC/Rw values or thermal resistance (R-value) for your specific application.

Yes. DualShield is designed for practical on-site application: it can be supplied with a pressure-sensitive adhesive backing (e.g., butyl-type) or as non-adhesive rolls/sheets for bonding with recommended adhesives. The mat can be cut, shaped and trimmed to fit floor, wall, ceiling, trunk, door panels, HVAC housings and equipment enclosures. For best results, clean and dry the substrate, apply firm pressure to ensure adhesion, seal seams where needed, and follow ASLONG installation guidelines. We also provide installation support, drawings and OEM/ODM options for specialized projects.

ASLONG develops products with environmental and regulatory compliance in mind. DualShield formulations are offered with low‑VOC and halogen‑free options, and we can supply third‑party test reports on request. Typical documentation available upon customer request includes material composition reports, VOC testing, and performance tests to relevant national or international standards (EN/ISO/ASTM). If you require specific fire ratings, chemical compliance (RoHS/REACH) or country-specific certifications, we will coordinate testing and documentation to meet your procurement needs.

To evaluate DualShield, request a sample and technical datasheet by contacting ASLONG at king@aslong.cc or visiting https://www.aslong.cc. We offer sample shipments, customizable thicknesses, backing types and roll sizes to match your project, with MOQ and lead times provided upon inquiry. ASLONG (Welllink Guangdong New Material Co., Ltd., established 2000) supplies acoustic and insulation solutions worldwide—and we are actively recruiting agents globally.
