Ventilation noise reduction net

Ventilation noise reduction net for metal roofs: integrates sound insulation and ventilation.

Ventilation noise reduction net is a functional material specifically developed to solve ventilation and noise problems in metal roofs and various buildings. Made of bonded polymer monofibers, it presents a soft and structurally stable three-dimensional mesh structure, combining three core functions: ventilation, noise reduction, and condensate drainage. It is an indispensable key component in metal roofing systems.

This product breaks the industry pain point of "ventilation and noise reduction being mutually exclusive." With its high-porosity three-dimensional mesh structure, it allows for free airflow, quickly draining condensate and rainwater residue from the roof interlayer, preventing moisture damage and aging of the base layer, and extending the lifespan of the building roof. Simultaneously, it effectively absorbs and refracts sound waves, significantly reducing noise generated by raindrops hitting the metal roof, while blocking other outdoor noise infiltration, creating a quiet and comfortable indoor environment.

This product is made of environmentally friendly and durable materials, is easy to install, and offers high cost-effectiveness. Customized specifications can be made to meet different project needs. It is widely compatible with various metal roofs and steel structure buildings. Having undergone long-term market validation, its stable performance has gained widespread industry recognition, making it a preferred ventilation and noise reduction solution that balances practicality and economy.

Product Principle

The Ventilation noise reduction net, with its unique three-dimensional mesh structure, achieves both ventilation and noise reduction functions. The core principles are as follows:

1. Noise Reduction Principle: The product consists of a high-porosity three-dimensional mesh formed by the bonding of polymer monofibers. When sound waves (such as the sound of raindrops hitting a metal roof) penetrate, they undergo multiple absorption, refraction, and damping processes within the mesh structure. The sound wave energy is gradually dissipated, significantly reducing noise propagation efficiency and effectively weakening indoor noise levels, creating a quiet environment.

2. Ventilation and Condensation Removal Principle: With a porosity ≥95%, the product, laid between the waterproof membrane and the metal roof panel, forms a natural ventilation channel. Through air convection between the eaves and ridge, it quickly removes condensation caused by temperature differences within the roof interlayer. Simultaneously, it facilitates the evaporation of infiltrated rainwater, preventing moisture from flowing between the base layer and the metal layer, thus preventing roof dampness and corrosion and extending the lifespan of the building roof.

Installation Steps (Simple and Quick, No Professional Team Required)

• Substrate Preparation: Clean the surface of the metal roofing waterproof membrane, ensuring it is free of debris, oil, and standing water. Keep it dry and flat, avoiding sharp objects that could scratch the product.
• Size Cutting: Cut the Ventilation noise reduction net to the required size according to the actual roof dimensions, leaving an appropriate overlap (5-10cm recommended) to ensure seamless installation.
• Laying and Fixing: Evenly lay the cut mesh on the waterproof membrane surface, ensuring it is flat, without wrinkles or damage. Secure it evenly with fasteners to prevent loosening. Install as you go. When using with aluminum-manganese-magnesium alloy panels, simply lay it between the two.
•  Sealing and Finishing: Seal the overlaps and edges using waterproof sealant to ensure there are no air or water leaks. Installation is now complete.
