Insulating Walls with Fiberglass
When you are insulating (2×4 as well as 2×6 mounted exterior wall cavities and intend to use fiberglass insulation, what density is best? The question becomes all more vital due to the long-term nature of wall cavity construction and wall insulation: Once the insulation is installed the wall and also nailed up with drywall, it is hard to change out.
When you add inadequate insulation, you will certainly have a colder home. Yet installing excessive insulation– packing in greater than is required– can additionally cause a colder home than is required. Tiny air pockets created within the insulation are what help keep a house cozy and also warm, not the tiny strands of fiberglass or paper kraft facing. Striking an excellent balance between inadequate insulation and also excessive insulation will keep you and also your family members cozy throughout the winter season.
Fundamentals of unFaced Fiberglass Insulation, From R Thirteen to R Nineteen
R-value is a conventional device of measurement for determining, among lots of points, how efficient your insulation will be. The R describes absolute thermal resistance. Greater R-value numbers suggest that the fiberglass material withstands the coolness or warmth from the outside better. Thickness, width, and also manufacturer of materials are some factors that add to R-value.
Insulation for Two by Four Wall Cavities
Many wall cavity assemblies, particularly those in older residences, are built with two-by-four (2×4) studs. Because contemporary two-by-fours are not 4 inches, truth depth of the wall stud is 3 1/2 inches.
In most wall cavity applications, you will use R-13 or R-15 kraft-faced fiberglass batts for these two-by-four stud walls. While rated in different ways, these 2 kinds of insulation are close enough in thickness that they can both suit modern-day two-by-four wall cavity systems. With R15 being a high density product, it is better for sound deadening. However it costs about 70 percent more than R 13.
Older homes, particularly those pre-dating the 1950s, might use two-by-fours that really are 2 inches by 4 inches. In this instance, you can still use R-13 or R-15 fiberglass insulation. There is no 4-inch deep unfaced fiberglass insulation in batts or rolls on the common market.
Insulation for 2 by 6 Walls
Some more recent residences may have walls constructed with 2×6 studs. Install R-19 or R-21 kraft-faced fiberglass insulation for two-by-six walls. This combination ensures that the insulation is neither too loose nor too securely compressed within the wall stud.

U.S. Department of Energy Recommended Total R-Values
The following 2008 Department of Energy zone recommendations are based on comparing estimated future energy savings to the current cost of installing insulation. The DOE gives a range for many locations for the following reasons:
- Energy costs vary greatly over each zone
- Installed insulation costs vary greatly over each zone
- Heating and cooling equipment efficiency varies from house to house
- Best estimate of future energy costs may not be exact.
