Insulation for Exterior Walls
There are different ways to insulate the exterior walls of a home. The most common methods consist of using R21 high density, R15 high density, R19, R13 or R11 fiberglass batts, these are all used in different situations. R21 meets current energy codes for new construction, and is installed to 2x6 faming; R15 is “code” for new construction and is installed to 2x4 framing. R19 is the most common product installed to garage walls. R13 and R11 is usually installed to “retro fit” homes with 2x4 walls.
Another product, or system, is the Blown In Blanket aka Bibs. Bibs are second to none for the increased thermal coverage & quality they provide. “BIBS” are installed by putting up a netting type of material & attaching it to the framing of the wall. Loose fill blowing insulation is then injected into the cavity, thus creating a seal around the cavity which is superior to that of a fiberglass batt.
Rigid foam board is used when you are dealing with a shallow wall void cavity. Rigid board insulation has a high R value for its slim width. For example, you can get R30 out of 4.5 inches with this product.
