Fiberglass Needle-Punched Felt | 700°C Heat Resistant | Acoustic Insulation

Manufactured from ultra-fine E-type glass fibers through specialized needle-punching technology, this nonwoven material creates a microporous structure offering exceptional thermal insulation and acoustic absorption properties. As a 100% inorganic, binder-free material, it outperforms traditional insulation materials like glass wool and asbestos products.
