Condensation Felt For Steel Construction

This condensation felt for steel construction, exclusive to Chinese manufacturer Xiashi Packing, solves metal roof issues: structural condensation, wall mold and loud rain noise. It is a top long-term supply material for steel workshops, warehouses and large venues.

What is condensation for steel construction?

The Jinbo Metal Roof condensation for steel construction is a specialized hydrophilic fiber layer developed by Xia's Packing in 2012, designed for use on metal roofs and walls of various steel structure buildings. The product employs a hot-melt self-adhesive composite process, allowing direct bonding with color-coated steel plates through on-site cold pressing for integrated molding.

The fiber core of the packing material undergoes highly hydrophilic modification, enabling rapid adsorption of condensation water equivalent to 6–7 times its own weight. Upon elevated ambient temperature, the stored moisture within naturally volatilizes and dissipates, thereby addressing the issue of condensation and dripping on metal sheets at its root cause.

The material also exhibits excellent noise reduction performance, significantly mitigating the noise generated by rainwater impact on metal surfaces; it further inhibits mold growth, slows steel corrosion, protects the building's structural integrity, and extends its service life. Widely applicable to structures with significant temperature variations, high humidity, or a tendency for condensation—such as steel-framed factories, warehouses, stadiums, and livestock shelters—it serves as an energy-efficient, durable, and easy-to-install primary protective material for buildings.

Working Principle of Condensation for steel construction

The Jinbo condensation for steel construction employs a novel high-performance fiber substrate and undergoes comprehensive deep hydrophilic modification. Leveraging its unique hydrophilic adsorption pore structure, it rapidly captures condensation vapor generated by temperature differences within buildings, with a water retention capacity up to 6–7 times its own weight, and exhibits no water leakage or dripping after adsorption.When the ambient temperature rises and relative humidity decreases, the moisture stored within the felt gradually diffuses outward and evaporates, achieving a dynamic equilibrium of water absorption and moisture dispersion.

The product features a built-in hot-melt self-adhesive composite layer that ensures tight adhesion and seamless integration with metal roof and wall panels without requiring additional reinforcement materials. It effectively resolves condensation and water dripping issues on roofs and walls in steel structures caused by indoor-outdoor temperature differences, reduces mold growth, mitigates rain-induced noise, and enhances building durability as well as indoor comfort for both living and working environments.

FAQs

Q1: What is the primary function of this condensation for steel construction?

Jinbo Metal Roof Condensation Prevention Felt can adsorb condensation water equivalent to 6–7 times its own weight, effectively addressing the issue of condensation and water dripping on steel structure roofs at its source.

It simultaneously reduces rainwater noise by 15–20 decibels, inhibits wall mold growth and steel corrosion, and significantly extends the service life of metal roofs by 10–15 years.

Q2: Can special facilities such as cold chain warehouses and livestock farms also be used?

Fully compatible. The product is suitable for various steel structure buildings with high humidity and significant temperature variations.

In cold chain applications, it reduces cooling energy loss and prevents cargo mold growth; in livestock sheds, it eliminates roof water drainage, thereby lowering disease incidence and mortality rates among animals.

It can also be effectively deployed in industrial facilities, sports venues, light steel villas, and other scenarios.

Q3: Is the product installation process complex? Can it be used directly with color-coated steel plates?

The construction is simple: the product employs a hot-melt self-adhesive composite process, allowing direct bonding to metal sheets and instant one-piece molding through on-site cold pressing without requiring additional reinforcement materials, resulting in high processing and installation efficiency.
