Product Introduction

Centrifugal glass wool is an artificial inorganic fiber insulation and thermal material made primarily from molten glass through a centrifugal blowing process. It features lightweight properties and is environmentally friendly, making it widely used in fields such as construction, industry, and HVAC systems.

Core Features

1. Excellent thermal insulation: The fibers form a three-dimensional network structure with numerous enclosed air pockets, resulting in a low thermal conductivity (typically ranging from 0.032 to 0.040 W/(m·K)). This effectively prevents heat transfer, making it ideal for insulating building exteriors, roofs, and pipelines.
2. Excellent sound absorption and noise reduction: With their fluffy, porous structure, these fibers effectively absorb airborne sound waves, minimizing ambient noise. They are commonly used in spaces requiring soundproofing, such as conference rooms, machine rooms, and KTVs, delivering noise reduction levels of 20–40 decibels.
3. Lightweight yet moderately strong: With a low bulk density (typically 24–96 kg/m³), it significantly reduces the load on structures or equipment while still offering good compressive and tensile strength. It resists deformation well and is easy to cut and adhere during construction.
4. Safety and Environmental Protection: The main component is glass, which contains no harmful chemicals like formaldehyde. It meets the non-combustible standard for fire performance and does not release toxic gases even at high temperatures, making it fully compliant with both environmental protection and fire safety requirements.
5. Excellent weather resistance: Resistant to aging and corrosion, with stable performance across a temperature range of -40°C to 200°C. It maintains its integrity over long-term use, showing minimal chalking or flaking, and boasts a service life of up to 10–20 years.

Common product forms

Rolled felt: Available as continuous rolls, typically 1.2 meters wide with customizable lengths, ideal for large-area flat surfaces such as roofs and walls, offering high construction efficiency.
Plate-shaped: Rigid or semi-rigid boards with thickness ranging from 50 to 150 mm, featuring uniform dimensions. They are commonly used for pipe wrapping, insulation of equipment housings, and soundproofing partition walls.
Shell: Arc-shaped and tubular, with an inner diameter that matches the pipe, specifically designed for insulating cylindrical equipment such as water pipes and steam lines. It fits snugly against the pipe surface, minimizing heat loss.

Applicable Scenarios

1. Construction sector: Exterior wall insulation for residential buildings, interior soundproofing layers, roof insulation, as well as acoustic treatments for public buildings such as shopping malls and hotels.
2. Industrial Applications: Insulation of equipment and pipelines in power plants and chemical facilities, as well as external thermal insulation for boilers and kilns, helping to reduce energy consumption.
3. HVAC: Insulation and soundproofing of air conditioning ducts to prevent condensation, while minimizing the impact of operating noise on the indoor environment.
4. Transportation Sector: Interior soundproofing layers for cars and trains, filling materials for highway noise barriers, helping to reduce traffic noise pollution.

Construction Advantages

Easy to install, it can be flexibly cut to size using tools like knives or saws as needed. Simply pair it with a specialized adhesive and insulation pins for secure fastening—no complicated equipment required. Plus, the installation process produces no dust pollution, making it ideal for quick, on-site assembly.
