Glass Wool Sandwich Panel | A1 Non-combustible Sound Absorbing Insulation Panel For Factory Wall And Roof

Glass wool sandwich panel, also known as glass fiber sandwich panel, is a prefabricated building panel with inorganic glass wool core and double pre-painted steel facings. This glass wool sandwich panel stands out for its A1 non-combustible grade and superior sound absorption performance. You can also check our rock wool sandwich panel product page for alternative high-density fire insulation panel options.

Different from rock wool panels, our glass wool sandwich panel is lighter in weight with excellent noise reduction capacity. It releases little toxic smoke when exposed to fire, which is critical for workshops, equipment rooms and public buildings with strict acoustic and fire codes. This glass wool sandwich panel adopts interlocking design for fast on-site installation to shorten construction schedules.

Each glass wool sandwich panel is produced by continuous hot pressing composite technology. Reliable bonding prevents delamination, even in long-term humid outdoor environments.

Our glass wool sandwich panel uses porous glass fiber as the core. The porous fiber structure traps sound waves to achieve great sound absorption, meanwhile slowing heat transfer for thermal insulation. The outer color steel cladding shields the glass wool core from rain, moisture and UV damage.

Thanks to its low-smoke fire performance and acoustic feature, glass wool sandwich panel is widely preferred for projects where both fire safety and noise control are required. It maintains consistent insulation and sound reduction performance under normal and humid working conditions.

Our glass wool sandwich panel fits projects requiring fireproof and sound absorbing building materials:

All raw materials of glass wool sandwich panel will be inspected before production. We test glass wool density, steel coating thickness and adhesive strength for every batch.

Finished glass wool sandwich panel goes through dimension check, surface inspection and fire & acoustic sampling test. Strict QC avoids peeling, bulging and leakage issues after installation.

As a professional manufacturer of glass wool sandwich panel, we support custom sizes and colors based on your construction drawings.

Factory direct sales remove middlemen to offer competitive wholesale prices. We provide installation guidance, technical drawings and sample service for contractors, distributors and prefab builders.
