Glass Fiber Insulation Felt
Composed of interwoven ultra-fine glass fibers, the felt features an internal structure with numerous interconnected micro-pores. Paired with an eco-friendly, odorless binder, it is asbestos-free, contains no harmful additives, and has formaldehyde emissions far below industry standards. It can be directly applied to both indoor and outdoor sound insulation projects without adverse effects on human health or the environment. Its flexible nature allows tight fitting to complex structures, adapting to diverse construction scenarios.
- Product Introduction
Products Description
Our Glass Fiber Insulation Felt is manufactured from high-quality glass raw materials using sophisticated centrifugal spinning technology. Molten glass is fiberized, bonded with an eco-friendly thermosetting resin adhesive, and processed through heating, curing, trimming, and rolling to form a flexible felt sound insulation material. As a man-made inorganic fiber product, it is primarily used for noise isolation and vibration attenuation across various applications, with auxiliary thermal insulation properties. It is widely recognized as one of the superior fire-resistant, sound-insulating, and sound-absorbing materials available today.
Product Advantages
High-Efficiency Sound Insulation & Noise Reduction
Based on the core principle of active sound absorption, sound waves entering the internal pores of the felt collide and rub against fiber surfaces, converting acoustic energy into thermal energy for rapid attenuation.
eco-friendly materials
Featuring inorganic glass fiber as the core material, it is non-combustible, smoke-free, non-toxic, and does not release harmful gases at high temperatures.
Excellent Durability
Glass fiber inherently resists corrosion, aging, and moisture. When exposed to humid or acidic-alkaline environments long-term, it will not mold, shed, or deform, with a service life of 15–20 years and no need for frequent replacement.
Sound Insulation & Thermal Insulation
Alongside high-performance sound insulation, it offers outstanding thermal insulation, effectively reducing heat transfer between indoor and outdoor spaces and lowering energy consumption.
Pre-Installation Preparation
Clean the installation base to ensure it is flat, dry, free of oil, dust, and debris. Uneven surfaces may cause loose laying and sound leakage gaps.
Cut the Glass Fiber Insulation Felt according to the area and application, leaving a 5–10 cm margin for splicing to avoid large gaps from insufficient sizing.
Prepare compatible auxiliary materials including specialized adhesive, sealant, and aluminum foil tape, ensuring they are non-corrosive and non-hazardous.
Product Precautions
During installation, avoid scratching the Glass Fiber Insulation Felt with sharp objects to prevent structural damage and compromised sound insulation performance. Replace or repair the material promptly if damaged.
Store Glass Fiber Insulation Felt in a dry, well-ventilated, cool warehouse. Protect it from direct sunlight, rain, and moisture. Keep away from ignition sources and corrosive substances. Stacking height shall not exceed 2 meters to prevent deformation.
Wear gloves during installation to avoid direct skin contact with glass fibers. If contact occurs, rinse thoroughly with clean water; no harmful effects will result. Clean up leftover scraps promptly after installation to prevent waste and environmental pollution.
Sound insulation requirements vary by application. We recommend consulting our technical team before installation for a customized solution to ensure the expected sound insulation performance.
FAQ
Q:Does the sound insulation performance of Glass Fiber Insulation Felt relate to thickness and density?
A:Yes. Sound insulation performance is positively correlated with thickness and density: greater thickness and higher density result in better noise reduction.
Q:Does glass fiber lint or flake off after installation?
A:No. Our product uses an advanced curing process that bonds glass fibers tightly to the adhesive, preventing lint formation. Additionally, the surface can be laminated with aluminum foil or other facings upon request to further eliminate fiber shedding. All raw materials are eco-friendly and non-toxic, posing no risk to human health.
Q:Can the product be cut to any size?
A:Yes. Thanks to its high flexibility, the felt can be freely cut to any size or shape to meet construction requirements and fit complex applications.
