It is so low that it is below many industry standards. When determining how much insulation you need don t guesstimate calculate. The most common and least expensive way is to install it right on top of your current wood siding. Existing 3 4 inches of insulation.

Aging effects comments. This is negligible however as a fully insulated exterior should have an r value of 13. In simple terms r values measure the effectiveness of insulation and a higher number represents more effective insulation. Here s a brief list of siding materials and their r values.

When doing this insulation is first installed over your original wood siding giving you double the insulation value. In hardwood it is 0 71. Per inch r value of softwood is 1 41. For instance while a brick veneer will only get you an r value of around 0 11 vinyl siding typically has a measurement of 0 61.

This value when compared to other insulating materials is actually pretty low. Most siding materials have an r value of less than 1. Logs of around 6 inches would then have an r value that is about 8. Insulation or other building material 9.

Most such r value tables ascribe an r value of r 0 87 for wood shingle siding. The higher the r value the greater the insulation performance. That includes standard vinyl steel or aluminum siding without added foam insulation. With no insulation behind either material wood siding is slightly more energy efficient having an r value of 0 81 to 0 87.

R value measures how well certain building insulation materials can resist heat. If you are using thicker 5 8 inch shingles the installed siding will have an r value of at most about r 1 9. If any readers think that the r value of cedar shingles might be higher it s worth consulting standard r value tables for a reality check. The vinyl is then applied on top of this insulation.

Non insulated aluminum steel or vinyl. Specifically here s how the different types stack up against one another. These extra layers or thickness brings the siding farther away from the house. Recommended insulation levels for retrofitting existing wood framed buildings.

Vinyl siding without insulation has an r value of 0 67. Add insulation to attic.
