Product Description

Product Description

Core Product Features
1)Outstanding Thermal Insulation and Energy Saving
Low thermal conductivity greatly slows heat transfer, reduces heating and cooling energy consumption for buildings, pipelines and equipment, cutting long-term operation costs. Its insulation performance remains stable for decades without attenuation.
2)Powerful Sound Absorption and Noise Reduction
Porous tangled fiber structure traps sound waves effectively, lowering reverberation and mechanical noise from ventilation ducts, factories, machinery rooms and partition walls to create quiet environments.
3)High Mechanical Strength and Dimensional Stability
Tightly bonded fiber structure delivers great compression and tensile resistance. It will not sag, shrink or delaminate after long-term use, ideal for external wall thermal insulation and overhead filling works.
4)Water Repellent, Anti-mold and Anti-corrosion
Natural hydrophobic property prevents water penetration. It resists mildew, rot and metal corrosion, maintaining stable performance even in humid basements, outdoor walls and pipeline systems.
5)Non-toxic and Eco-friendly
Made from natural mineral raw materials, free of asbestos, formaldehyde and harmful volatile substances. It causes no skin irritation during installation and is safe for both commercial and residential indoor environments.

Packaging & Shipping

1.  Standard Packaging
1)Inner shrink wrapping: Each mineral wool roll and slab is tightly wrapped by transparent shrink plastic film, fully sealed to lock moisture, block dust and prevent fiber spillage.
2)Reinforced woven outer bag: The bag is printed with brand logo, specifications, thickness, density and shipping marks, stitched tightly and fixed with binding straps for anti-tear performance. Custom private label printing is supported.
2. Transportation and Storage Reminders
1)Tight shrink packaging delivers outstanding waterproof performance, adapting to long-distance sea, land and air transportation globally.
2)Store goods in dry and ventilated warehouses, keep away from sharp objects and heavy compression to prevent package breakage and product deformation.
3)We cooperate with professional international freight forwarders, offering worldwide logistics services including FOB, CIF, DDP and door-to-door delivery.
4)Complete shipping documents such as commercial invoice, packing list, CO and product test reports will be provided to realize smooth customs clearance
3. Packaging Advantages
1)Compact shrink wrapping avoids loose fibers, ensuring clean and tidy construction sites without flying wool dust.
2)Dual-layer shrink film + woven bag waterproof and dustproof design fully protects product quality from factory to construction site.
3)Clear printed labels on outer bags simplify stock counting, warehouse management and receiving inspection for buyers.

FAQ

Q1:How does mineral wool thickness affect sound absorption effect?

A1: Thicker mineral wool batts deliver higher NRC (Noise Reduction Coefficient). From 40mm to 100mm thickness, the NRC rises from 0.85 up to 1.20, with outstanding sound absorption at medium and high frequencies (500–4000Hz).

Q2:Which one is better for sound insulation and fire resistance, glass wool or mineral wool?

A2: Glass wool has finer fibers with an NRC of 0.75-1.24, delivering superior sound absorption effect; mineral wool boasts higher temperature resistance up to 600°C and stronger fireproof performance for high-temperature and exterior wall fire projects.

Q3:What standard wall structures can your mineral wool fit?

A3:It matches 2.5" (64mm) and 3-5/8" (92mm) 25-gauge steel studs with 24" on-center spacing. You can use single/double layers of 13mm or 16mm gypsum drywall on both sides, paired with 51mm–76mm mineral wool for different STC grades.

Q4:Is this mineral wool suitable for both sound control and fire protection?

A4:Yes. This mineral wool is designed for integrated sound and fire control insulation, widely used for partition walls, ventilation duct insulation and building noise reduction projects.
