Steel Buildings Sweat Because The Skin Is Cold, And Spray Foam Insulation Warms It
A steel-clad shop drips in spring and fall because the inside face of the cladding is below the dew point of the air inside. Fibreglass blanket with a vinyl facing traps that moisture and sags. Closed cell spray foam insulation bonds directly to the steel between the girts and purlins, keeps the inside face warm and dry, and adds enough stiffness that the panels stop oil-canning in the wind. Two inches is a common wall spec and three on the roof; the quote states it.
Boat Storage, Marinas And Buildings On The Water
Indoor boat storage on Lake Simcoe and Lake Couchiching holds a lot of damp fibreglass in a cold building for six months. Condensation dripping from a roof deck onto stored boats is a real cost. Spray foam insulation on the roof deck and the upper walls stops the drip, and it lets the building be kept just above freezing for a fraction of what an uninsulated shell costs to heat. Service bays and shops at the marinas get the same treatment and become workable in January.
Pole Barns, Horse Barns And Equipment Sheds
A pole barn in Oro-Medonte with a steel roof rains on the equipment inside it every March. Foam on the underside of the roof and on the walls stops it, and the same building becomes a shop or a heated barn for the price of the foam. Horse barns need ventilation kept in the design; we insulate the shell and leave the air changes to the barn plan. Where livestock or feed are present the foam is covered with a tested coating or a panel, and that is written into the quote.
Commercial Work Is Scheduled Around The Business
Retail, office and service buildings around Orillia are usually sprayed after hours or in sections so the business keeps running. Cold storage, mechanical rooms and additions are staged with the site contractor. Every commercial quote names the product, the thickness, the area and the thermal barrier or coating that Ontario's code requires over foam, so the number a property manager takes upstairs is the whole number.
