Trailer spray foam insulation in Edmonton is mostly work on units that are in service through the whole year rather than seasonally. In a city with this much construction and industrial activity, a great many trailers are offices, lunch rooms and secure stores that somebody occupies daily.
Site offices that run all winter
A site office trailer is a workplace, and at Edmonton temperatures an uninsulated one is close to unusable no matter what heater is put in it. The heat goes out through the skin as fast as it is produced, the floor stays cold because there is nothing under it, and condensation forms on every metal surface as soon as people are inside. Treating the shell turns a heater that was fighting the building into one that is keeping up with it.
The roof is the surface that swings hardest
On any trailer the roof takes the sun during the day and radiates to a clear sky at night, so it swings further and faster than the walls. That makes it the first surface where condensation appears and the one that matters most for summer heat as well. Where a budget will not stretch to the whole unit, the roof is generally where it goes first.
Horse and livestock trailers on a long haul
A trailer carrying animals for any distance in this climate has a real moisture load inside it and a cold skin around it, which is the classic condensation combination. The considerations are the same as any other unit but the tolerance is lower, because what is inside is affected by the conditions rather than merely stored in them.
What can and cannot be sprayed
Not every part of every unit is a candidate. Areas that have to be removable for service, anything that needs to stay accessible, and surfaces that are not sound enough for foam to adhere to are all worth identifying before the work rather than during it. A short walk around the unit settles it, and it avoids the awkward conversation where something has been covered that should not have been. On a unit that will be resold later that matters more than it first appears.
Trailer Spray Foam Insulation Edmonton: Common Questions
Our site office is unusable in winter. Will this fix it? It addresses the cause. The heat is leaving through the skin as fast as it is produced, and sealing and insulating the shell is what lets a heater keep up.
If we can only do part of it, what comes first? Usually the roof. It swings hardest in both directions and is where condensation appears first.
Is anything off limits? Anything that has to stay removable or accessible for service, and any surface not sound enough for foam to adhere to. Worth identifying on an Edmonton unit before the work starts.
