A hog barn is one of the hardest environments in agriculture for a building envelope. Hundreds of animals produce constant heat and humidity, ventilation runs continuously, and winter temperature differentials are extreme. Get the insulation wrong and you pay for it in feed conversion, herd health, and fuel bills.
The Moisture Problem
Livestock humidity condenses on any cold surface — ceilings, wall panels, purlins. Chronic condensation corrodes steel, rots wood framing, degrades batt insulation into wet mats, and drips onto animals and equipment. Wet buildings also drive ammonia and air-quality problems that ventilation alone can't solve.
Closed-cell spray foam is impermeable to moisture and bonds continuously to the ceiling and walls. There are no gaps, no compressed corners, no vapour barrier seams to fail. The interior surface stays above the dew point, so condensation stops — permanently.
The Energy Math
Heated barns in SW Ontario winters lose most of their heat through air leakage and thin envelope assemblies. Foam seals and insulates in one pass, which stabilizes interior temperatures, reduces heater runtime, and makes ventilation systems work the way they were designed to — exchanging air for air quality, not fighting envelope losses.
Retrofit Reality
We regularly spray operating barns between groups or during scheduled downtime. Based in Leamington, we've worked in hog, dairy, and poultry buildings across Essex County and Chatham-Kent — and we mobilize anywhere in Ontario for larger facilities. Call us and we'll plan the application around your production schedule.
