Poultry barn spray foam insulation in Edson is work on small buildings on acreages rather than on large commercial operations. The flocks are modest, the buildings are frequently something that was adapted, and the problems are consistent across nearly all of them.
Litter that will not dry in this climate
Everything in a poultry building comes back to moisture, and here the usual route out of the building is partly closed. Ventilation removes damp air by replacing it with drier air, and for a good part of the year the air outside an Edson barn is not much drier than the air inside it. So litter that would dry down in a prairie barn stays wet, and wet litter is the start of nearly every health and air quality problem a small producer runs into. The envelope matters because it decides whether the building can be warmed enough for the air inside to hold and carry moisture out.
The ceiling above the birds is where it lands
The coldest surface in one of these buildings is the ceiling or the underside of the roof, and that is where the moisture in the air condenses. It then drips back down onto the litter, which makes the litter wetter, which puts more moisture into the air. That loop is the reason a small barn can get progressively worse through a winter rather than staying level. Insulating and sealing that plane breaks it, and it is the first surface to treat on almost every building of this kind.
Short daylight and what it means for the building
For weeks in midwinter here there is very little natural light, and supplementary lighting is running for most of the day. That is a heat input, a moisture-free one, and on a small barn it is not negligible. It also means the building is closed and lit for long stretches, which is exactly the condition in which air quality declines quietly. Producers who plan the ventilation around the lit hours rather than around the outside temperature tend to have better birds.
Why a heat lamp is the wrong tool once the shell is sealed
The default fix in a cold small barn is a lamp or two. In an unsealed building they are heating the outdoors and everybody knows it. In a sealed building they become a genuine hazard, because they are a high-temperature source in a dusty enclosure with combustible bedding, and clearances that were tolerable in a draughty barn are not tolerable in a tight one. Sealing the building changes the heating conversation, and the correct answer is a modest, properly installed heat source rather than more lamps.
Poultry Barn Spray Foam Insulation Edson: Common Questions
Why does the litter never dry out? That is the local condition. The envelope decides whether the barn can be warmed enough for the air to carry moisture out.
Where do we start? The ceiling plane above the birds. It is the coldest surface and it is where the water forms.
Can we keep using heat lamps? Once the building is sealed they are the wrong tool. A modest fixed heat source is safer and works better.
