Trailer Insulation
Insulation is a key factor in maintaining consistent temperatures inside refrigerated trailers. Proper insulation allows the refrigeration unit to use less energy to keep products chilled or frozen during transport. Trailers designed for refrigerated use have walls, ceiling, and floor constructed of insulation materials to reduce heat transfer. Commonly used insulation includes:
Polyurethane foam panels - A popular choice due to its excellent insulating properties and moisture resistance. Panels are bonded to the interior surfaces of the Refrigerated Trailer structure.
Polystyrene foam boards - Another good insulator that is durable and easy to install. It is often found as a butt jointed liner inside refrigerated trailer walls and ceilings.
Fiberglass batts - An economical option that provides decent insulation. Fiberglass batts are fitted snugly between structural members of the walls and ceiling.
Insulation thicknesses may range from 2 to 5 inches depending on the trailer design and intended cargo temperatures. Proper sealing of joints and openings is also important to maintain an insulated barrier. Regular maintenance checks help ensure insulation remains intact for maximum efficiency.
