What is Industrial Wool Felt?
Industrial Wool felt is a dense, non-woven textile produced by matting, condensing and pressing wool fibres together. Unlike woven or knitted fabrics, felt forms through fibre entanglement, typically using heat, moisture and mechanical action.
Industrial wool felt is engineered for durability, thermal stability and resilience, and it is available in a range of densities, thicknesses and finishes to meet diverse industrial requirements.
Key properties
Thermal insulation: Wool fibres have natural insulating properties and good heat resistance. Felt provides steady thermal performance across a wide temperature range.
Acoustic damping: The open fibre network absorbs and dissipates sound and vibration, making felt useful for noise control.
Compression resilience: High-density felts resist deformation and recover well after load cycles, offering cushioning and sealing performance.
Moisture handling: Wool can absorb and release moisture without losing structural integrity; this moderates humidity and can reduce condensation in assemblies.
Chemical and flame behaviour: Wool is naturally flame-retardant compared with many synthetic fibres

SAE Specifications Products
Pressed wool felts are made from high-quality wool fibres which are mechanically pressed using heat, moisture, and pressure. The process is mandated by SAE standards which determine the wool content, density, and other properties.
