Insulation Rock Wool Strip

Product Details

The insulation rock wool strip is a strip-shaped thermal insulation material made from natural basalt and mineral slag as primary raw materials. It is produced through high-temperature melting and centrifugal fiber formation, followed by special directional fiber laying and curing technology. The fibers are arranged vertically to the board surface, granting the product not only excellent fire resistance and thermal insulation properties but also superior tensile and compressive strength compared to standard rock wool boards. It is an ideal solution for thin-layer exterior wall insulation systems and curtain wall thermal protection applications.

This material is widely used in building insulation and energy-saving systems, providing enhanced structural stability and high-performance thermal protection.

Core Value Highlights

Excellent Fire Resistance and Safety Protection

As an A-class non-combustible material, it effectively prevents flame spread and forms a strong fire barrier, significantly enhancing building safety standards for public and residential structures.

High Tensile Strength and Structural Stability

The unique vertical fiber structure provides outstanding pull-out resistance, allowing the material to securely integrate into external wall systems and resist deformation or detachment caused by wind pressure and self-weight.

Long-Lasting Thermal Insulation and Energy Efficiency

The fiber structure contains closed air pockets that effectively block heat transfer, maintaining stable indoor temperatures across seasons and reducing heating and cooling energy consumption. This contributes to improved energy efficiency and cost savings.

Hydrophobic and Moisture-Resistant Performance

With strong water-repellent properties, the material resists moisture absorption, preventing degradation of thermal insulation performance and mold growth. This ensures long-term durability and stable system performance.

Environmentally Friendly and Easy to Install

Manufactured from inorganic mineral materials, it is chemically stable, odorless, and environmentally safe. Standardized strip dimensions and lightweight characteristics facilitate easy handling, cutting, and installation, improving construction efficiency.

The insulation rock wool strip is a reliable solution for modern building energy efficiency, fire protection, and structural safety. It is widely applied in exterior wall insulation systems for both new construction and renovation projects.

Core Application Areas

02 Curtain Wall Insulation Systems

Application: Thermal insulation layers for stone, metal panel, and glass curtain wall systems.
Value: Provides a continuous fire barrier and structural stability within cavity spaces, ensuring safe and reliable insulation performance in curtain wall applications.

03 Fire Protection Systems

Application: Fire isolation belts, window and door opening seals, and floor-level fire barriers.
Value: As an A-class non-combustible material, it effectively blocks flame and smoke spread, serving as a core component of building fire protection systems.

04 Specialized and Industrial Applications

Application: Expansion joint filling and thermal insulation for industrial equipment and pipelines.
Value: Adapts to complex shapes and requirements, providing reliable thermal protection and energy efficiency while maintaining fire safety.

Application by Building Type

High-rise buildings: Enhances wind resistance and fire safety compliance.

Public facilities (schools, hospitals, malls): Provides maximum fire protection.

Industrial plants and warehouses: Combines insulation and fire safety to reduce operational energy consumption.

Energy retrofits: Improves building energy efficiency and safety without altering exterior appearance.

Technical Parameters

Installation and Storage Recommendations

Installation Guidance

Pre-Installation Preparation

Substrate Treatment: Ensure the wall surface is firm, level, clean, and dry, free of oil, dust, and loose debris.

Environmental Conditions: Installation is recommended at temperatures between 5°C and 35°C. Avoid construction during rain, snow, or strong wind.

Material Inspection: Verify product specifications and ensure materials are dry and undamaged.

Installation Best Practices

Adhesive Application: Use full-bond or strip-bond methods with specialized polymer adhesive. Bonding coverage should meet design requirements (typically ≥60%).

Staggered Joints: Install with staggered seams, ensuring overlap of at least one-third of the board length. Corner joints should be interlocked for stability.

Mechanical Fastening: Install anchors after adhesive initial curing. Anchor quantity, specifications, and depth must meet design standards, typically positioned at seams and center points.

Joint Treatment: Gaps should not exceed 2 mm. Larger gaps must be filled with rock wool strips or foam insulation materials to ensure tight sealing.

Safety Measures

Personal Protection: Workers should wear gloves, masks, and goggles to prevent fiber contact with skin and respiratory pathways.

Fire Safety: No open flames are allowed on-site. Fire extinguishing equipment must be available.

Storage and Management Recommendations

Storage Conditions

Indoor Storage: Store in dry, ventilated areas on pallets to avoid direct ground contact.

Moisture Protection: Prevent exposure to rain and humidity, as water absorption can degrade insulation performance.

Avoid Overstacking: Do not stack materials too high to prevent deformation under excessive pressure.

Handling Guidelines

Maintain Original Packaging: Keep packaging intact until installation to protect product integrity.

Gentle Handling: Avoid dropping or impact to prevent edge damage.

Following these recommendations ensures optimal product performance, construction quality, and extended service life of the insulation system.

FAQ

Q1: What is the fire rating of rock wool strips, and where can they be used?
A1: Rock wool strips are A-class non-combustible materials meeting the highest fire safety standards. They are ideal for fire isolation belts, curtain wall sealing, and cable penetration fire barriers, effectively preventing flame spread and enhancing building fire safety.

Q2: What density ranges are available, and how should I choose the right product?
A2: Density typically ranges from 80 kg/m³ to 180 kg/m³. Selection depends on application:

80–100 kg/m³: Suitable for filling and non-load-bearing partitions.

120–150 kg/m³: Ideal for curtain wall insulation with strength and thermal performance.

160 kg/m³ and above: Used for high-strength industrial or specialized applications.

Q3: Do I need special adhesives or fasteners for installation?
A3: Yes. Specialized polymer adhesives and anchors are recommended to ensure system reliability and prevent detachment risks associated with generic adhesives.

Q4: Does installation generate dust, and how can I protect workers?
A4: Minor fiber dust may occur during cutting. Recommended precautions:

Ensure proper ventilation.

Use masks, goggles, and gloves.

Prefer standard sizes to minimize on-site cutting.
