Can polystyrene insulation be used outside?

Extruded polystyrene (XPS) and foil-faced polyisocyanurate (polyiso) are high-density rigid-foam insulations that can be used as exterior insulation and are generally approved, per Building America(SM) to be used as a drainage plane if the joints are sealed.

What is fanfold insulation used for?

Fanfold insulation is an extruded polystyrene foam insulation which is designed to be applied to the exterior walls of homes, between sheathing (or pre-existing sidings) and usually vinyl siding. Its purpose is to provide thermal protection and to form a second barrier between the elements and the framing.

How is fanfold installed?

A. Install TRI-BUILT® Fanfold Underlayments directly over old siding using galvanized or aluminum roofing nails, with nails spaced about 2 feet apart. If the existing siding is damaged, remove it and install TRI-BUILT® Fanfold Underlayment directly to the substrate.

Should you tape fanfold insulation?

To be an effective weather-resistive barrier, though, the seams of the fan-fold must be carefully taped, since any seam can provide a pathway for water to reach the structure under the foam. As long as the foam is not foil-faced, the best tape is contractor’s tape from 3M.
