Heat and Sound Insulation Felt is a polyester insulation felt made of Phenolic Felt.

• Energy Saving: Provides energy savings thanks to its high heat and sound insulation.
• Flame Retardant: The material is flame retardant, enhancing safety.
• Health-Safe: Not harmful to health, free of carcinogenic substances.
• Comfortable Use: Does not require special protective equipment during use and does not cause irritation or itching.
• Heat Conductivity Coefficient (λ): 0.030 W/mK.
• Sound Absorption: Its 3D structure absorbs sound waves with high capacity.
• Hygienic: Free from bacteria, fungi, mold, and insects.
• Eco-Friendly: Made from Phenolic Felt fibers, making it friendly to both nature and humans.
• Long-Lasting: Durable material.
