One of the biggest problems in barns and farm buildings used for animal husbandry is condensation and sweating under the roof. Especially due to animal waste and the humid environment, there is constant vapor formation indoors. This vapor condenses on uninsulated metal or sheet metal roofs, leading to serious problems over time.
How Does Sweating Occur?
When the warm and humid air inside the barn comes into contact with the cold roof surface, it turns into water droplets. This leads to:
Constant moisture formation on the inner surface of the roof
Corrosion and decay on metal surfaces
Significant shortening of the roof's lifespan over time.
Risks to Animal Health
Water droplets formed by condensation can drip directly onto the animals. This can cause:
Continuously wet floors and bedding
Respiratory diseases
Weakening of the immune system
Loss of productivity. This is a serious health risk, especially in enclosed areas where cattle and small ruminants are kept.
How Does Spray Polyurethane Foam Provide a Solution?
When 2-component spray polyurethane foam is applied under the roof, it:
Creates a strong thermal barrier between the metal surface and the indoor environment
Significantly reduces condensation
Protects the inner surface of the roof sheet
Prevents dripping
Provides a more stable temperature indoors
Additionally, thanks to its seamless application, it creates a homogeneous insulation layer without joints.
Additional Advantages
Extends roof life
Improves indoor humidity balance
Reduces energy loss
Creates an easy-to-clean surface
For these reasons, under-roof spray foam application is increasingly preferred in modern barn projects.
