Which way does foil roofing plywood go on.

In essence retrofitting is a way to install insulation in the roof walls and floors of a building after it has been built. Traditional sheathing allows the sun s radiant heat to enter a home through the roof and walls which can cause extreme attic temperatures heat transfers and ultimately higher energy bills. Radiant barrier roof sheathing is a great product that will reduce your power bill. The process is more tricky than installing foil insulation during the construction of a property but can be undertaken if need be.

There are just a few manufacturers that make this unusual type of roof sheathing that has a shiny perforated aluminum foil craft paper laminated to one side of it. The foil layer of the osb lowers the delta t because the foil is low emitting and does not emit or absorb heat. So when the sun hits the roof and radiates into the attic or wall the foil layer of the osb sheathing reflects the heat to the roof or exterior wall which keeps the top layer of the insulation just a few degrees warmer than the. The foil insulation goes on top of the moisture barrier followed by the roof covering.

You want to make sure that you are building a quality roof that will last you for decades to come but you need the right kind of plywood for the roof. For shear wall construction code requires blocking between the studs along every plywood joint. Dropping the plywood joint below the plate creates a joint across the studs. I wonder if a hurricane or an earthquake can really tell the difference.

Basically plywood or osb sheathing with a thin aluminum facing on one side radiant barrier sheathing installs like any other roof sheathing. If you use bubble foil or rigid foam insulation it also goes on top of the moisture barrier. Although blocking is required by code for walls floor or roof plywood systems do not require blocking. Align the long edge of the sheathing with the ends of the.

You just have to keep the shiny side face down. The roof of your house covers and protects everything inside of those walls from the rain snow and sleet that come your way.
