Core Advantages of Aluminum Foil Glass Wool Board

Superior Thermal Insulation with Radiant Heat Block

The tangled fine glass fibers lock stationary air inside to minimize heat conduction, delivering thermal conductivity of 0.036–0.038 W/m·K at 25°C. Attached aluminum foil surface reflects radiant heat, adding an extra layer of thermal protection. It stabilizes indoor temperature, lowers power loads for air conditioning and heating systems, and prevents water condensation on duct or wall surfaces, especially useful in hot and humid regions.

A1/A2 Non-combustible Fire Performance

Made of inorganic glass fiber raw material with melting point exceeding 700℃. It complies with Euroclass A1/A2 non-combustible standard EN 13501-1. Under fire conditions, it will not burn, spread flame or release harmful toxic fumes. The aluminum foil lamination avoids molten dripping, which makes it a trusted choice for HVAC ducts, high-rise buildings, medical facilities and educational buildings with strict fire codes.

Effective Noise Absorption & Noise Reduction

The open porous structure of glass wool dissipates sound energy to cut down airborne noise and equipment vibration noise. The aluminum foil facing restrains sound reflection on the panel surface. It works well to reduce reverberation inside commercial spaces and suppress blower noise from ventilation pipelines.

Built-in Vapor Barrier Against Humidity

The reinforced aluminum foil skin tightly bonded to glass wool functions as a reliable vapor barrier. It blocks water vapor from seeping into the fiber core, stopping the glass wool from absorbing moisture and losing insulation capacity. This feature maintains long-term stable performance in tropical, coastal and high-humidity environments.

Simple Fabrication & Site Installation

This rigid glass wool board is lightweight and easy to trim to custom sizes using common cutting tools. The aluminum foil outer layer shields the fragile glass fiber core from damage during transportation and construction. Installers can attach it directly to air ducts, roof panels and interior walls, saving construction time and labor expenses.

Industry Applications

HVAC & Air Conditioning Duct Systems (Core Application)

This is the most common usage for foil-faced glass wool boards. The product is specially designed for internal and external insulation of ventilation ducts, air supply ducts and exhaust ducts. The glass wool core effectively reduces heat loss and maintains stable air supply temperature, while the aluminum foil layer acts as a professional vapor barrier. It completely isolates water vapor in the air, prevents duct surface condensation, dripping and mold growth, and protects the ventilation system from long-term corrosion and damp failure. Meanwhile, the porous fiber structure greatly reduces wind noise and equipment operating noise inside the pipeline, improving indoor environmental comfort. It is suitable for central air-conditioning systems in large and medium-sized buildings all year round, especially in high-temperature and humid tropical areas.

Commercial Building Wall, Roof & Ceiling Insulation

Widely used for thermal and acoustic insulation of office buildings, shopping malls, hotels, supermarkets, exhibition centers and catering buildings. Installed on interior walls, suspended ceilings and building roofs, the material effectively blocks outdoor high temperature and heat radiation, reduces air conditioning load, and achieves significant energy-saving effects. Its high sound absorption performance can reduce indoor reverberation, isolate outdoor noise and create a quiet commercial environment. In addition, the A1/A2 non-combustible property fully meets the fire protection requirements of dense commercial buildings.

Public Facilities & High Fire Standard Projects

Perfectly applicable for schools, hospitals, stadiums, subway stations, airport terminals and other public places with strict fire safety regulations. The inorganic glass wool material does not burn, does not spread flames, and releases no toxic smoke in high-temperature environments. It fully complies with international building fire codes. It can be used for wall insulation, ceiling sound insulation and pipeline fire protection of public buildings, ensuring long-term safety and stable building operation.

Industrial Workshops, Warehouses & Factory Buildings

Ideal for steel structure workshops, factory roofs, partition walls and large logistics warehouses. Industrial buildings usually have large heat dissipation areas and serious noise pollution. Our foil glass wool board can effectively insulate high-temperature heat from steel roofs, reduce indoor temperature difference, improve factory working environment, and lower enterprise energy consumption. At the same time, it can weaken mechanical vibration noise and workshop reverberation, realizing dual functions of heat preservation and noise reduction for industrial buildings.

Residential Building Decoration & Construction

Suitable for high-end apartments, villas and residential renovation projects. It is commonly used for ceiling insulation, interior wall sound insulation, roof heat insulation and partition wall noise reduction. The material is lightweight, safe, non-toxic and formaldehyde-free, meeting residential green building standards. It effectively isolates outdoor noise and floor noise, improves living comfort, and avoids indoor overheating in summer and heat loss in winter.
