In simple terms r values measure the effectiveness of insulation and a higher number represents more effective insulation.
Siding with r value.
The table below shows what levels of insulation are cost effective for different climates and locations in the home.
In fact that is code in many areas.
R value is a measure of insulation s ability to resist heat traveling through it.
To put the r value of insulated siding into perspective walls with 2 x4 construction are typically insulated in the r 13 to r 20 range depending on the type of insulation selected.
The insulation also adds some r value or insulating quality to the siding.
The truth is no standard siding material offers very good efficiency.
The higher the r value the better the thermal performance of the insulation.
The higher the r value the better the thermal performance of the insulation.
Achieving greater r values in exterior walls in exterior walls add insulating sheathing to achieve a greater r value in your wall system.
Building materials are given an r value which is a measurement of how well that material resists the conductive flow of heat or how well it insulates.
The energy efficiency for building materials is known as r value.
For instance if you have a material with an r value of 12 attached to another material with an r value of 3 then both materials combined have an r value of 15.
You can achieve better thermal performance in your attic by adding an additional layer of insulation.
Notes on the r value k values of different forms of asbestos.
These benefits make insulated vinyl seem like an easy worthwhile upgrade to conventional vinyl but there s a significant cost increase with insulated vinyl and many builders and homeowners question whether the price premium is worth it.
It has an r value of r 5 with its foam layer nearly 1 thick.
Vinyl and lp wood siding have similar r values around 6 with lp siding having the edge.

The higher the r value the more efficient the building material is.
Notes to the table above.
Rosato asbestos insulation is the most authoritative source on asbestos properties and gives data for the thermal conductivity of asbestos in different forms and with varying temperatures for magnesia asbestos insulation at mean temperatures ranging from 100 f to 400 f the k value thermal.
Most energy experts suggest that your home s walls should have at least an r 13 energy efficiency.
R value see table 2.
In construction the r value is the measurement of a material s capacity to resist heat flowfrom one side to the other.
