Product Details

Achieve superior thermal and acoustic insulation with this cheap thermal glass wool board from China, designed for various construction applications. The aluminum foil covering enhances its functionality by creating an effective vapor barrier while reflecting heat, significantly improving energy efficiency in walls, ducts, and roofing systems. This quality thermal glass wool board is manufactured from durable materials including silica sand and dolomite, creating a dense fibrous structure that effectively traps air to minimize heat transfer and reduce noise penetration between spaces.

The practical benefits of this insulation solution make it ideal for both professional and DIY projects. Builders can rely on this cheap thermal glass wool board from China to maintain consistent indoor temperatures while lowering energy costs throughout the year. The aluminum foil facing adds durability and simplifies installation, ensuring long-term performance without compromising on value. As a proven quality thermal glass wool board, it offers dependable performance that meets the demands of modern construction, providing an accessible insulation solution that doesn't sacrifice effectiveness for affordability.

product Introduction

Glass wool slab is placed in the glass of meltdown appearance proceed the fiber turn and spray the resin of solid that draw the hot silk wadding form material, then turn through hot solid the deep processing handles and can also make into the series andvarious products.  Glass wool slab is processed by putting the thermosetting binder into the glass wool, by pressing and heating, and then, by curing. They are widely used for insulation ,ventilation and the adjustment of air-conditioner incommercial industry and residential construction. Meanwhile, it has the effect ofenergy-saving insulation, sound controlling and improving the indoor air quality. glass wool slab is rigid but flexible product and no corrosion to the tank or pipe surfaceeasy to install and fixed with wire or banding and clip, then covered by galvanized sheet or aluminum sheet to protect the glass wool from UV, weathering influence.
