Formaldehyde-Free Glass Wool – Frequently Asked Questions

formaldehyde-free glass wool HVAC application EcoIn

According to Wikipedia, glass wool is an insulating material made from fibres of glass arranged using a binder into a texture similar to wool. Formaldehyde-free glass wool replaces conventional phenol-formaldehyde binders with eco-friendly alternatives, eliminating indoor VOC emissions and earning green building certifications.

What makes formaldehyde-free glass wool different from standard glass wool?

Standard glass wool uses phenol-formaldehyde resin as a binder, which can off-gas formaldehyde indoors. EcoIn formaldehyde-free glass wool replaces this binder with a bio-based or acrylic alternative, achieving zero formaldehyde release per GB50325-2001. The thermal and acoustic performance of formaldehyde-free glass wool remains unchanged: density 20–80 kg/m3, thermal conductivity 0.034–0.062 W/m.K, Class A1 fire rating.

EcoIn formaldehyde-free glass wool is classified non-combustible with a Class A1 reaction-to-fire rating per GB 8624-2012. It does not contribute to fire spread or produce toxic smoke, making it suitable for fire-rated wall assemblies, HVAC duct linings, and acoustic ceiling applications in schools, hospitals, and high-rise buildings.

EcoIn formaldehyde-free glass wool is used for wall and roof insulation in metal and timber-frame buildings, HVAC duct insulation, acoustic ceiling tiles, and industrial insulation for boilers and machine rooms. Its zero-formaldehyde characteristic makes it ideal for LEED-certified projects and buildings where indoor air quality is a priority. For blanket-format insulation, see our glass wool blanket.

EcoIn formaldehyde-free glass wool is available in thickness from 25 mm to 180 mm and density from 20 to 80 kg/m3. The fibre diameter is 5–8 μm, moisture absorption is ≤5% by volume, and hydrophobicity is ≥98%. Sound absorption coefficient at 2000 Hz reaches 1.03 (reverberation method, 24 kg/m3). Custom sizes and densities of formaldehyde-free glass wool are available on request.
