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.

The very best usages for R 19
Some more recent homes may have wall surfaces constructed with 2×6 studs. Use R-19 or R-21 kraft-faced fiberglass insulation for two-by-six (2×6) walls. This mix makes sure that the insulation is neither as well loosened neither also snugly loaded within the walls.
Uses for R-19
In lots of regions of the country, R-19 insulation is recommended for application in outer walls of brand-new construction projects. A various sort of insulation is utilized in places like basements as well as attic rooms, as well as to shield floors. Since R-19 insulation is just over 6 inches thick, it is well-suited for use in building projects that make use of 2-by-6-inch studs; it fits securely in the wall surface and also protects against air from flowing through voids in the plywood on the walls.
Upgrading to R 21
R-21 insulation has a higher compactness than R 19, although it is designed to fit into the exact same space. It often tends to be somewhat thinner than R-19 as a result of its density. Both been available in rolls and are installed similarly. R-21 insulation is extra efficient at protecting against the transfer of heat, yet it costs more per square foot. Building firms frequently make use of R-19 as the conventional insulation and might use R-21 insulation as an available upgrade to customers.
Worth Over Time
Deciding whether to make use of R-19 or R-21 insulation is mostly a issue of considering instant expenses over long-term savings. Depending upon the costs of each type of insulation and the overall square footage of the building project, it may make more feeling financially to mount the extra costly insulation due to the fact that it will certainly save you cash over time. However if the task is very large, R-19 could be the far better choice since it may take a long period of time to recover the distinction in insulation expenses.
Why Too Much Insulation Can be a Bad Thing
Fiberglass insulation functions in part by trapping air pockets within the insulation. If you pack way too much insulation into a wall surface that is also slim, you minimize the insulation’s air pockets as well as thus lower its capacity to provide thermal resistance.
A thick down-filled coat or sleeping sack works similarly. When the feathers fluff up as well as produce air pockets, thermal resistance reaches its greatest. Bags or jackets that are wet or have actually been rolled up for a long period of time do not retain body warmth because there are less and also smaller sized air pockets.
This is one reason sprayed or rigid foam insulation functions well. Millions of little air pockets are generally pre-installed in the insulation as well as they can not be forced away.
