Product Overview: Formaldehyde-free Glasswool Blanket

Formaldehyde-free glasswool blanket (also known as no added formaldehyde glass wool roll or low-VOC insulation blanket) represents a flexible, lightweight insulation material composed of fine glass fibers bonded with a plant-based, formaldehyde-free binder. Specifically, the ECOSE Technology binder is based on rapidly renewable bio-based materials rather than petroleum-based chemicals. Consequently, this eco-friendly composition delivers excellent thermal insulation, sound absorption, and moisture resistance while significantly improving indoor air quality.

TARCO Industry produces its formaldehyde-free glasswool blanket from high-quality quartz sand, limestone, dolomite, and recycled glass cullet containing up to 80% recycled glass content. During production, we melt these raw materials at high temperatures and fiberize them into fine filaments. Ultimately, the plant-based binder, which contains no added formaldehyde, phenols, or acrylics, bonds the fibers into a super-soft, low-dust, and odourless insulation product suitable for a wide range of building applications.

Key Features & Benefits of Formaldehyde-free Glasswool Blanket

Furthermore, the formaldehyde-free binder contains no added formaldehyde, phenols, or acrylics, making it safe for installers and building occupants. Additionally, the product generates low volatile organic compounds (VOCs), helping to improve indoor air quality and contributing to healthier building environments. Moreover, the binder is based on rapidly renewable bio-based materials rather than petroleum-based chemicals, significantly reducing the product’s environmental impact. Consequently, low thermal conductivity of 0.032–0.049 W/m·K effectively reduces heat loss and improves energy efficiency in buildings. Therefore, the product is super-soft, low-dust, and odourless, making it pleasant to handle and install. In addition, it is non-hygroscopic, rot-proof, and resistant to microbial growth for long service life. Furthermore, the advanced compression packaging provides more product per pack, reducing transportation and storage costs. Finally, formaldehyde-free glasswool blanket is naturally non-combustible without the need for toxic fire retardants, achieving Euroclass A1 fire classification.
