Quonset spray foam insulation in Taber is most often asked about for a building holding a season's inputs, and that is the hardest thing to keep in an arch, because seed and fertiliser take up moisture out of the air and the shape delivers it straight back to them.
Nobody builds these any more, which is the first thing to weigh
Every arch on a Taber yard was put up decades ago and nothing going up now is that shape. Farms build flat-sided, tall-doored, clear-span buildings instead, because equipment got bigger and because a rectangular building is easier to use and to extend. That matters before any technical question, because money going into a quonset is going into a building type the operation has already decided against, and the useful conversation is whether this one has a job worth keeping it for.
What damp does to inputs is not gradual
Fertiliser cakes and stops flowing, treated seed loses what it was treated with, paper sacks fail at the bottom of a stack, and labels come off containers that legally have to carry them. None of that happens slowly and none of it is recoverable, which is why an inputs store is worth more attention than its size suggests. On a Taber yard the value sitting in one of these through the winter is frequently larger than the value of the building several times over.
The job it is still genuinely good at
Cold, dry, secure cover for things that do not care about temperature, which on a crop operation is a long list: implements, drums, hose, fencing, anything seasonal. For that use the arch is excellent and it costs very little to make it work, because sealing a curved surface is straightforward and there is nothing else the building has to do. A Taber owner who wants that and is told they need a conditioned building is being oversold, and one who wants a workshop and is told the arch will do it is being undersold.
Deciding it in the same conversation as the replacement
The sensible way to settle this on a Taber yard is alongside whatever the operation is planning to build next. If a new building is three years out and will take over what the arch is doing, then the arch gets the smallest sensible spend and nothing more. If nothing is planned, the arch is the building for the next fifteen years and it deserves to be treated properly. What produces waste is spending on it as though nothing were coming and then building anyway, which is the commonest version of this on a yard that is growing.
Quonset Spray Foam Insulation Taber: Common Questions
Why does the trouble start at the top of the stack? The shape funnels rising air to the crown and what forms there drips straight back down.
Is it worth spending on? Depends what is going up next. If a new building will take over its job, spend the minimum.
What is it still good for? Cold dry secure cover, and it is very good at that for very little money.
