Trailer spray foam insulation in Calgary covers a wide range of units that share one problem. A trailer is a thin metal shell with a large surface area relative to its volume, so it follows the outside temperature faster than any building does and condenses moisture on the inside of its own walls.
Cargo, horse and site-office trailers want different things
A cargo trailer used for tools and stock is about keeping contents dry and stopping the contents from cooking in July. A horse trailer is about the animals and the moisture they produce over a long haul. A site-office trailer is about somebody working in it through a Calgary winter. Those are three different targets and it is worth naming which one applies before anything is priced, because the specification changes considerably between them.
A large surface area for a small volume
The reason a trailer behaves so differently from a room of the same size is the ratio between its skin and the space inside it. There is a lot of metal for a small volume of air, so heat leaves quickly, arrives quickly and the interior swings with the weather. Insulating the shell is what slows that down, and because the metal is the structure it has to be done to the inside face rather than in a cavity.
Frames, ribs and the floor
As with any metal-skinned unit the framing runs from inside to outside, so it is covered rather than filled around. The floor is the part most often left out and, in a trailer somebody stands in all day, the part they notice most. It is worth confirming whether the floor is in the scope because it is frequently assumed to be and frequently is not.
Doors, vents and the seal around them
Every door and vent in a trailer is a hole in a small envelope, and their surrounds matter more here than they would in a building because there is so little else. Sealing those perimeters is part of the job, and on a Calgary unit that is used year round it is often what makes the difference between a trailer that holds and one that does not.
Trailer Spray Foam Insulation Calgary: Common Questions
Will it stop the inside sweating? That is the main reason people do it. Foam removes the cold metal surface the moisture is condensing on rather than catching what runs off it.
Does the floor get done too? Only if it is in the scope, and it is worth asking. In a unit somebody works in it is the surface they feel most.
Is a Calgary summer part of the case? Yes. A bare metal trailer is a solar collector, and the same layer that holds heat in during winter keeps it out in July.
