Working principle

Condensation occurs when water vapor transforms into liquid water. Simply put, when atmospheric moisture reaches saturation and the ambient temperature drops further, the air cools to a point where condensation forms; this moisture then adheres to the coldest surfaces, creating "condensate."

1. Absorption: Jinbo® Non Drip Anti Condensation Felt is made by a high-performance, reliable fiber fabric with strong hydrophilic properties. Upon contact with condensate, it rapidly absorbs the moisture, lets it holding up to 6–7 times its own weight.

2. Retention: Functioning much like a sponge, high-quality anti-condensation felt typically absorbs 0.2 to 1.0 liters of water per square meter, works well to lock the moisture within its fibers.

3. Evaporation: When the external temperature rises, the trapped moisture evaporates back into the atmosphere. The felt dries out, ready to function again when new condensation occurs.

The Difference Between Traditional Condensation Felt and Non Drip Anti Condensation Felt

Test item	Conventional Product (Old)	House Dress Jinbo® Anti-Dripping Felt (New)
Thermal Conductivity	≥ 0.35 W/(m·K)	≤ 0.028 W/(m·K) – comparable to premium insulation
Surface Temperature Difference	Inner surface close to outdoor temp ≤ 3°C	Maintains of 8–12°C between inner surface and outdoor
Corrosion Protection	No protection; fastener rust visible in 12–18 months	Steel components remain corrosion-free for 10+ years under normal use
Service Life	Needs to be replaced every 5 to 8 years.	Has the same lifespan as the metal sheet.
