Insulating shipping container homes

Insulated shipping container homes is best done on the outside, around the tank from corrosion and moisture deposits on the inside, UNLESS insulating foam spray for protection is based used on interior walls. Traditional home is isolating done on the inside with fiberglass or rock wool Batts, insulating container home in this way only leads to corrosion and condensation on the inside walls due to infiltration by means of interior vapor barrier and damp. Insulating is a container house best with insulating foam or spray polyurethane foam is, and this insulating material sticks sprayed steel walls and, depending on thickness, you can expect R3.5 per inch for the open cell or closed cell foam for R7 per inch. Spray foam insulation inside walls of rust proof seals, the building and eliminates energy robbing cold air infiltration and the associated problems with mold and condensation problems, steel is an excellent conductor, so it is also a good idea to give the outside a thin layer to prevent bridging of insulating foam. A quotation for spray foam insulation (depending on where you live), $ 0.50 + per square meter for open cell / inch thickness, or $ 1.20 + for closed cell per square meter / inch thickness
