Anti Condensation Film

This Anti condensation Film roll material is made of hydrophilic modified fiber fabric via hot-glue lamination. It absorbs 6–7 times its weight in water, adheres directly to steel plates, and can be cold-pressed or cut on site. A mainstream choice for bulk procurement in steel structure projects.

What is the Anit Conensation Film？

Anti condensation film is a specialized self-adhesive functional fiber building material designed for steel structure buildings, developed and manufactured by Xiashi Packing Co., Ltd. in Xiong' an New Area (Xiongxian County) in 2012. It serves as a core component routinely procured and purchased in bulk for metal roofs and color-coated steel wall projects, widely used in all steel structure buildings including industrial plants, warehouses, sports venues, food industry parks, and livestock sheds. Metal frames experience significant daily temperature fluctuations; when damp air inside the building contacts low-temperature metal surfaces, condensation readily forms.

Anti condensation film utilizes its fiber properties to cycle through soaking, holding, and releasing moisture naturally,so nothing drips or leaks down onto inventory and machinery: it rapidly absorbs condensation at night, locking moisture to prevent dripping or leakage; during daytime temperature rises, the absorbed moisture gradually evaporates, restoring the material's dryness—a continuous cycle that provides long-lasting anti-condensation protection and fundamentally addresses the issue of condensation in metal buildings.

What is the working principle of Anti Condensation Film?

The Anti condensation film is made of hydrophilic treated fibers, addressing condensation issues in metal structures through a dynamic cycle of water absorption, storage, and natural evaporation, with the entire process is divided into two stages:

1.Nighttime/Low-temperature phase (Absorbing & Storing Water)

When humid and hot indoor air comes into contact with low-temperature metal plates, it condenses into liquid condensate. The hydrophilic fibers of the felt rapidly absorb moisture, with a water storage capacity up to 6–7 times its own weight.The fabric holds droplets firmly so nothing drips or leaks, and it keeps wetness off metal panels to avoid rust from forming.

2.Day / Heating phase (Evaporate & Dry Out)

When surrounding temperatures rise again, water trapped in the fiber weave evaporates little by little, and normal air flow takes the vapor outside. The felt dries fully once more. It can cycle this process time and again, delivering steady long-term protection against condensation.

Product Advantage

Condensation Control：This anti condensation film works well in humid areas and places with big day-and-night temperature changes. It stops dew droplets from forming on metal roofs, protecting indoor goods, equipment and the entire steel building structure. It is a highly practical material for cold storage rooms, breeding houses, and all kinds of steel structure projects, especially in humid southern coastal areas.

Noise Reduction：Metal roofs produce loud noise when hit by rain or hail. This felt absorbs most of the impact sound and makes indoor working environments much quieter. It fits well for offices, food processing workshops and any area that requires a quiet space.

Rust, Mold & Corrosion Resistance：The material comes with natural antibacterial and anti-mold performance. It keeps condensed water off the metal surface to prevent corrosion and slow down overall material aging. It also helps you cut repeated purchases of anti-rust and maintenance supplies, effectively reducing daily operating expenses.

High construction efficiency: The self-adhesive structure can be integrated with metal plates during manufacturing, simplifying construction procedures and shortening project timelines, fully meeting the requirements of centralized procurement, large-scale supply, and phased delivery for major engineering projects.

High weather resistance: resistant to extreme temperatures and UV-induced aging; does not powder or delaminate even after years of outdoor exposure, making it suitable for long-term procurement across projects nationwide.

Application Case

The steel structure industrial building (12,000 sqm) is located in a high-humidity area with a daily temperature variation of 10–14°C. It has a water absorption capacity of 1,200 g per square meter, effectively eliminating condensation drips; noise levels during heavy rainfall have decreased from 80 dB to 57 dB; the structural panels show no corrosion, and annual operation and maintenance costs have been reduced by 62%. The facility has been in stable operation for five years.

The fresh food cold chain warehouse (6,800 sqm) maintains an indoor-outdoor temperature difference exceeding 30°C and a humidity level above 90%. With a moisture adsorption capacity of 8 hours and an evaporation rate of 96%, moisture-related loss of goods has decreased from 2.8% to 0.5%, while refrigeration electricity costs have been reduced by 17%

Livestock and poultry breeding sheds (15,000 m²): The humidity within the sheds ranges from 85% to 92%. The incidence of mold growth decreases by 95%, the prevalence of livestock and poultry diseases reduces by 24%, construction duration is shortened by 28%, and overall costs are reduced by 18%.

FAQs

Is the construction process complex, and does it require additional adhesive?

Answer: Equipped with built-in adhesive, it can be directly attached to color-coated steel plates or profiled steel sheets, supporting on-site cutting and cold pressing without additional adhesive application, ensuring simple installation.

Which areas are suitable for installing anti-condensation felt?

Answer: Primarily used for metal roofs and steel plate composite walls, suitable for steel structure buildings such as factories, warehouses, sports venues, livestock sheds, and cold storage facilities.

Can it function properly under high and low temperature conditions?

Answer: It exhibits a wide temperature tolerance range, maintaining stable performance in environments from-30°C to 80°C without brittling at low temperatures or adhesive loss at high temperatures.

Will prolonged outdoor use lead to aging or damage?

Answer: Possesses resistance to UV-induced aging; can be used for many years under normal operating conditions without powdering or delamination.
