DERFLEX Condensation Control Membrane Made with Fine Denier Spunbond Nonwovens

The DERFLEX condensation control membrane—reinforced with advanced Fine Denier Spunbond Nonwovens—is designed to safeguard livestock buildings by preventing condensation, blocking acidic gas corrosion, and improving overall environmental conditions inside barns and shelters.

Why Livestock Buildings Need Condensation Control

In pig houses, cattle barns, poultry farms, and other enclosed livestock facilities, high humidity and temperature variations often cause severe roof condensation. In addition:

• Condensation drips fall continuously and keep the barn damp.
• Ammonia and acidic gases from manure rise and attack the metal roofing.
• Corrosion accelerates, reducing the lifespan of roof sheets.
• Poor environmental conditions negatively affect animal health and farm productivity.

DERFLEX provides a professional, proven solution.

Product Introduction: Condensation Control Membrane (Fine Denier Spunbond Nonwovens)

The membrane consists of a thick, absorbent Fine Denier Spunbond Nonwoven layer combined with a strong self-adhesive backing. It adheres directly to the inner surface of metal roof panels and performs multiple essential functions:

Key Functional Advantages

• Fast Moisture Absorption: The Fine Denier Spunbond Nonwovens quickly capture condensation as it forms.
• Temporary Moisture Storage: Captured water is held safely within the fiber structure without dripping.
• Natural Evaporation: Stored moisture evaporates gradually as airflow increases.
• Corrosion Protection: The membrane blocks acidic gases from reaching the metal panel.
• Temperature Reduction: The membrane can reduce interior surface temperature by up to 9°C.

Product Features

• High absorbency due to fine-denier fibers
• Excellent dimensional stability
• Self-adhesive, quick installation
• Long-term anti-corrosion protection
• Anti-drip function to maintain dry barn conditions
• Durable, chemical-resistant nonwoven structure
  
  
  

Product Specifications

Product Application

• Pig houses (swine farms)
• Cattle barns
• Poultry houses
• Sheep farms
• High-humidity coastal livestock areas
• Ventilation-limited barn structures

Case Study: Coastal Pig Farm in Southeast China

Project Background

A pig farm located in a humid coastal region suffered from severe roof condensation. Acidic gases from manure accelerated corrosion on metal roof panels, resulting in high maintenance costs and shortened roof lifespan.

Installation

• DERFLEX membrane with Fine Denier Spunbond Nonwovens
• Self-adhesive installation
• Total coverage: 16,000 m²

Improvement Mechanism

• The membrane absorbs condensation immediately.
• Moisture is stored in the fine-denier fibers and evaporates gradually.
• Metal roofing is protected from acidic gases and corrosion.

Results

• Dripping significantly reduced.
• Roof corrosion slowed dramatically.
• Barn environment remained dry and cleaner.
• Inner roof temperature reduced by up to 9°C under heat exposure.
