Glass Wool Insulation Roll / Board – Lightweight Thermal & Acoustic Insulation for Roofs, Walls & HVAC – Non-Combustible & Energy Saving

Haoou Glass Wool is a high-elasticity insulation material made from recycled glass and silica sand, melted and spun into ultra-fine flexible fibers. The interlaced fiber structure traps still air, providing outstanding thermal resistance while dampening noise transmission. Available in rolls, batts, or rigid boards to suit various building applications.

Unlike traditional insulation materials, glass wool is naturally lightweight, resilient, and easy to handle – significantly reducing installation time and labor costs for contractors and builders.

Why Choose Haoou Glass Wool?

• Excellent Thermal Insulation
  Thermal conductivity as low as 0.032 W/m·K, helping maintain stable indoor temperatures and reducing HVAC energy consumption by up to 40%.

• Superior Sound Absorption
  Open porous fiber structure effectively absorbs airborne noise. Sound absorption coefficient (NRC) up to 0.90 – ideal for theaters, studios, offices, and residential partition walls.

• Class A1 Non-Combustible
  Made from inorganic glass fibers. Withstands high temperatures without burning or releasing toxic smoke. Complies with international fire safety standards.

• Lightweight & Resilient
  Low density (10–64 kg/m³) makes it easy to transport and install. High compression recovery ensures full thickness after packaging – no performance loss.

• Flexible & Easy to Install
  Can be cut with a standard knife. Rolls fit snugly between studs, rafters, or joists without gaps. No special tools or protective clothing required for cutting.

• Non-Hygroscopic & Mold Resistant
  Glass fibers do not absorb moisture. With proper vapor barrier installation, glass wool will not support mold, mildew, or bacterial growth.

• Eco-Friendly
  Contains up to 60% recycled glass content. Reduces building carbon footprint over its lifetime. 100% recyclable at end of life.
