Medicine Hat has one of the driest climates and some of the biggest daily temperature swings in Alberta, and it has a food and greenhouse sector that grew up around cheap energy. Cold storage spray foam insulation in Medicine Hat is usually working on a converted building in a climate that behaves unlike the rest of the province.
Dry outside does not mean dry inside
It is tempting to assume a dry region is an easy region for a refrigerated envelope. What matters is not the outdoor humidity but the difference across the assembly, and the inside of a cooler holding product is not dry. In summer the drive runs hard inward, from hot dry air into a cool moist box, and the condensing plane sits inside the wall where nobody looks. A dry climate changes where the problem appears; it does not remove it.
The daily swing does the damage
This part of Alberta routinely moves twenty degrees or more between afternoon and early morning. An envelope on a refrigerated building here is cycled every single day rather than seasonally, and cycling is what finds a seam, a fastener or a joint. Continuity is worth more in this climate than an extra inch of thickness, because thickness slows a steady loss while continuity is what survives repeated movement.
Greenhouse and food operations
The sector here includes packing, processing and controlled-environment growing, and those buildings often hold humidity deliberately. When a packing hall or a cold room is added inside an existing structure, the new temperature boundary usually runs straight through framing that was never intended to carry one. Foam applied continuously over that framing is what stops the structure becoming the path.
Older shells and what has to happen first
A lot of the refrigerated space in the Hat is inside buildings that were something else first. Rust, damaged cladding and previous patch repairs all have to be dealt with before anything is sprayed - foam does not bond to a corroding surface and covering one hides it. A shell put right first is the difference between a building that holds temperature for decades and one that has the same problem again in a hidden place.
Cold Storage Spray Foam Insulation Medicine Hat: Common Questions
Does a dry climate make this easier? It changes it rather than easing it. The inside of a cooler is not dry, and in summer the drive runs inward, so the condensing plane ends up inside the assembly instead of on a visible surface.
Why does the daily temperature swing matter? Because it cycles the envelope every day rather than every season. Repeated movement is what opens seams and works fasteners loose, and continuity handles it better than thickness does.
Does the building need repairs before insulating? Anything corroding or damaged should be sorted first. Foam will not bond to a rusting surface, and covering one puts the problem out of sight rather than fixing it.
