1/2" Polystyrine Foam Board InsulationThis is most common with vinyl siding. The foam board is nailed in place with washer head nails and should be taped at the seams to prevent air movement. The typical R-value of this product is R-2.5 to R-3.5 depending on the density of the foam board.

The reflective laminated surfaces are micro-perforated so that the insulation materials can “breathe,” offering both water vapour permeance and an air barrier.
Does house wrap help with insulation?
House wrap is a moisture and air barrier, and also provides a radiant barrier that helps to reduce heating and cooling costs by acting as an additional form of insulation.Is foam board a vapor barrier?
Rigid foam board, especially foil-faced polyisocyanurate, creates a vapor-impermeable barrier, so the wall would have limited drying potential. Even more permeable types of insulation, such as expanded polystyrene, are vapor barriers when the installation is thick enough.How long can house wrap be exposed?

With various facing solutions, the fiberglass insulation will result in a durable and attractive finish.What is the difference between open cell and closed cell spray foam?
Open cell foam is full of cells that aren't completely encapsulated. In other words, the cells are deliberatly left open. This makes the foam a softer, more flexable material. Closed cell foam is made up of cells that are, as the name suggests, completely closed.What's the best way to insulate a metal building?
