Product Overview: Glasswool Blanket & Glass Wool Roll
Glasswool blanket (also known as glass wool roll or glass mineral wool insulation roll) represents a flexible, lightweight insulation material composed of fine glass fibers bonded with a thermosetting resin. Specifically, the fibers are three-dimensionally entangled to create a porous structure that traps air. Consequently, this structure delivers excellent thermal insulation and sound absorption performance.
TARCO Industry produces its glasswool blanket from high-quality quartz sand, limestone, dolomite, and recycled glass cullet. During production, we melt these raw materials at high temperatures and fiberize them into fine filaments. Ultimately, the final product is a non-combustible, moisture-resistant, and chemically stable insulation material suitable for a wide range of thermal and acoustic applications.
Key Features & Benefits of Glasswool Blanket
Furthermore, low thermal conductivity of 0.032–0.049 W/m·K effectively reduces heat loss and improves energy efficiency in buildings and industrial systems. Additionally, a high sound absorption coefficient (up to 1.03 at 2000Hz, 24kg/m³) makes it ideal for noise control in walls, ceilings, and HVAC systems. Moreover, it provides a non-combustible Euroclass A1 / Class A fire rating, tested to EN 13501-1 and ASTM E136. Consequently, water repellency greater than 98% prevents condensation and mold growth. Therefore, it is easy to cut, wrap, and install on irregular surfaces, reducing labor costs. In addition, it offers anti-corrosion, anti-aging, and resistance to microbial growth for long service life. Furthermore, it is available with low-VOC and formaldehyde-free binders for green building projects.
