Heat-Resistant Thermal Insulation Rock Wool Blanket

Product Overview

Rock wool blankets offer excellent thermal insulation, high-temperature resistance, sound absorption, and mechanical strength. They are widely used in modern industrial and construction applications as essential insulation materials.

Particularly suitable for high-temperature equipment, industrial pipelines, large storage tanks, and complex curved structures, rock wool blankets provide flexibility, adaptability, and ease of installation, making them an ideal solution for improving energy efficiency in thermal systems.

Key Features

Exceptional Thermal Insulation

Low thermal conductivity (typically 0.033–0.045 W/m·K), significantly reducing energy consumption and improving thermal efficiency.

Excellent High-Temperature Resistance

Withstands temperatures ranging from 600°C to 650°C, ensuring stable performance under prolonged high-temperature conditions.

Effective Sound Absorption & Noise Reduction

The interwoven fibrous and porous structure effectively blocks sound transmission, offering high sound absorption coefficients ideal for noise control applications.

Outstanding Flexibility & Ease of Installation

Can be easily wrapped around irregular equipment, pipelines, and tank surfaces without the need for grooving or cutting, enhancing installation efficiency.

Superior Fire Resistance

Class A non-combustible material that does not burn or release harmful gases when exposed to fire, meeting stringent fire safety standards.

Water Repellency (Optional)

Treated with hydrophobic agents to enhance moisture resistance and prolong service life, suitable for variable environmental conditions.

Installation Method

The construction process of rock wool blanket is simple and quick, and can be installed in the following ways according to the application environment:

Binding and fixing: Use metal wire or insulation tape to fix the rock wool blanket to the outer surface of the equipment. Mechanical Cladding: Use stainless steel mesh or metal hoops for structural fixation, ensuring long-term stability.

Multi-Layer Installation: For high temperatures or special insulation requirements, a staggered, overlapping, multi-layer installation is recommended.

Metal Sheathing: Use with aluminum foil, galvanized sheet, or stainless steel outer sheathing to enhance waterproofing and mechanical performance.

Representative Case Studies

(1) Petrochemical Plant Thermal Pipeline Energy Efficiency Retrofit

- Multi-layer insulation wrapping with rock wool blankets reduced heat loss by 25%, achieving annual energy savings exceeding ¥1 million. The installation period was shortened by 30% compared to traditional board methods.

(2) Steel Structure Factory Building Roof Sound Absorption Project

- Rock wool blankets (80 kg/m³ density) were used as roof filling material within a metal panel system, reducing workshop noise by 15–20 dB and significantly improving workplace comfort.

(3) Central Air Conditioning Main Duct Insulation Project

- A dual-layer structure of rock wool blankets with aluminum foil lamination enhanced duct insulation efficiency. Stainless steel banding ensured structural stability and high fire resistance.

FAQ

Q1: Can rock wool blankets be used outdoors?

A1: Yes. We recommend using them with aluminum foil or metal facings and adding waterproofing treatment to enhance their aging resistance.

Q2: What is the difference between rock wool blankets and rock wool boards?

A2: Rock wool blankets are highly flexible and suitable for curved structures; rock wool boards are more suitable for flat surfaces and wall insulation and have greater pressure-bearing capacity.

Q3: Can we customize oversized sizes or special thicknesses?

A3: Yes, we offer custom production. Please provide us with your specifications and drawings, and we will respond quickly.

Q4: Is rock wool blanket environmentally friendly and safe?

A4: Yes, rock wool blankets are asbestos-free, non-toxic, and harmless. Our production process adheres to environmental standards, making them suitable for green building projects.

Q5: What is the service life of a rock wool blanket?

A5: Under normal operating conditions, rock wool blankets can provide stable service for over 20 years and are not susceptible to aging, deformation, or failure.
