Rock Wool Composite Panels For High-Temperature Applications

Product Introduction

Engineered to withstand high-temperature environments, these Rock Wool Composite Panels effectively integrate the exceptional thermal insulation properties of rockwool with the mechanical strength and durability of composite materials. The result is a versatile insulation product that offers low thermal conductivity, excellent fire resistance, sound absorption capabilities, and long-term dimensional stability.

These Rock Wool Composite Panels are widely specified for insulation and protection in a range of demanding scenarios, including:

Building curtain walls and façades

Roofing systems and ceiling insulation

Cold storage and refrigeration facilities

Industrial pipelines, vessels, and high-temperature equipment

By combining energy efficiency with robust mechanical performance, High-Temperature-Resistant Rockwool Composite Panels provide a reliable, cost-effective solution for reducing heat loss, protecting critical infrastructure, and enhancing overall system safety in both commercial and industrial settings.

Product Structure and Composition

Rockwool Core Material

Made from high-quality minerals melted at high temperatures, these inorganic fibers have uniform density and are slender, offering excellent thermal insulation, fire resistance, and sound absorption.

Composite Panels

Common surface materials include color-coated steel, galvanized steel, aluminum, stainless steel, or aluminum-magnesium alloy panels, offering excellent corrosion resistance, weather resistance, and aesthetics.

Adhesive

An environmentally friendly adhesive is used to firmly bond the rockwool core to the panel, ensuring the stability and durability of the overall structure.

Product Features

Excellent thermal insulation performance

Rock wool has a reasonable density and a thermal conductivity as low as 0.035-0.045 W/m·K, effectively blocking heat and cold conduction, improving energy efficiency in buildings and equipment.

Excellent fire resistance

As an inorganic material, rock wool composite panels are non-combustible or flame-retardant, with a fire resistance of over 3 hours, meeting various fire protection regulations.

Excellent water and moisture resistance

The composite panels effectively block moisture intrusion and prevent moisture absorption from the core material, ensuring long-term stability.

High-strength structural stability

The panels are tightly bonded to the rock wool core, resulting in high overall strength, impact resistance, and bending resistance, capable of withstanding harsh environments and mechanical stress.

Excellent sound insulation and absorption

The rock wool fiber structure effectively absorbs noise, reducing building and equipment operating noise and improving comfort.

Environmentally friendly and green material

Asbestos-free, non-toxic, and odorless, it complies with international environmental standards and meets green building certification requirements.

Technical Parameters

Production process

(1) Rock wool preparation

Rock wool fibers are produced by high-temperature melting of ore and then formed using special equipment to ensure uniform fiber and stable density.

(2) Core material cutting

Rock wool is cut into panels of required thickness and specifications according to the designed dimensions.

(3) Panel pretreatment

The steel or aluminum plate is cleaned and coated to improve corrosion resistance and adhesion.

(4) Composite molding

The core material and the panel are hot-pressed using a high-strength adhesive to form a strong and durable composite panel.

(5) Inspection and packaging

The rock wool composite panel after composite is quality tested and shipped to customers after packaging and protection.
