Insulation Materials Overview

Materials commonly used in buildings to control the outflow of indoor heat.

It is known as insulation material, while the material that prevents outdoor heat from entering the indoor space is called thermal insulation material. The insulation material is called Ducken Insulation Material. Common thermal insulation materials can be divided into two categories based on their composition: organic materials and inorganic materials. According to their form, they can be fibrous, porous, micro-porous, cellular, granular, and laminar, among others. Below is a brief introduction to some more common materials.

Inorganic fiber-insulating materials

1Mineral Wool, Rock Wool, and Their Products

Mineral wool is an insulating material in the form of cotton, primarily made from industrial waste slag by melting and then processed using blowing or centrifugal methods. Rock wool, on the other hand, is a type of mineral wool produced from natural rocks, commonly including basalt, dolerite, and amphibolite.

Mineral Wool Features: Mineral wool and its products are excellent thermal insulation materials with over a century of production and application history. They are lightweight, provide thermal and acoustic insulation, and have good chemical stability, non-flammability, corrosion resistance, abundant raw materials, and low cost.

The primary uses of mineral wool: Its products are mainly used for thermal insulation and sound absorption in the walls, roofs, ceilings of dry buildings, and can also be made into waterproof felts and sleeves for pipes.

2Glass wool and its products

Glass wool is a fibrous material made by melting glass raw materials or molten crushed glass, including short wool and ultra-fine wool.

Glass wool characteristics: Maintains excellent insulation properties under both high and low temperatures, offers good elastic recovery, excellent sound absorption for various sound waves and noise, good chemical stability without aging, and consistent performance over a long period. The product thickness, density, and shape can be processed according to customer requirements.

Primary Applications: Short cotton is mainly used to produce glass wool batts and rolls, which are utilized for building insulation and soundproofing, as well as for thermal insulation and soundproofing of ventilation and air conditioning equipment.

Ultra-fine cotton is primarily used to manufacture glass wool boards and glass wool pipe sleeves, which are employed for insulation and soundproofing in large recording studios, cold storage facilities, warehouses, ships, aviation, tunnels, and construction projects. It is also suitable for insulating pipelines for heating, water supply, and power equipment.

3Alumina Silicate Wool and Its Products

Alumina-silicate wool, also known as fibers with a diameter of3-5mThe company's alumina silicate fiber, also known as refractory fiber, is a  The company uses raw materials such as coking coal, high-purity alumina, silicon dioxide, zirconium sand, etc., selects appropriate processes, and melts or spins through resistance furnaces. These inorganic materials, made by polymerizing and fiberizing dispersible materials with the same chemical composition and structure but different structures, are currently considered as new types of thermal insulation materials both domestically and internationally.

Features: Light in weight, high-temperature resistance, low heat capacity, low thermal conductivity, excellent thermal stability, superior tensile strength, and excellent chemical stability.

Main Applications: Widely used for high-temperature thermal insulation sealing in industrial kilns across various industries such as power, oil, metallurgy, building materials, machinery, chemicals, and ceramics, as well as for filtration and sound-absorbing materials.
