What r value insulation for exterior walls

How do you calculate the are - value of insulation? Which insulation material has the highest R-value? What is the best your - value insulation? The higher the R - value , the better the thermal performance of the insulation.

You can achieve better thermal performance in your attic by adding an additional layer of insulation.

Why Too Much Insulation Can be a Bad Thing Fiberglass insulation works partly by trapping air pockets within the insulation.

Don’t compress or flatten the batting. It reduces the R - value. Your attic requires the most insulation–up to R-is recommended in all but the warmest climates. You also benefit from insulating exterior walls to a level of R-to R-21. Here’s a look at the best exterior wall insulation options.

Find out how to determine the R - value of the insulation in your attic and how much insulation you should have depending on your climate. Along with knowing the R - value of a particular insulation , it is also important to calculate the R - value of a total system. For example, a wall with ½” fiberglass batting ( R - value of 1 - 1) may have an overall R - value of nearly because of siding, sheathing and drywall.
