The range of R-values of insulation materials spans from materials with R-10 insulation values per inch like vacuum insulated panels and silica aerosol to below R-1 values per inch like bricks, glass, and poured concrete.
R-Value is a measure of insulation’s ability to resist heat traveling through it. The higher the R-Value the better the thermal performance of the insulation. The table below shows what levels of insulation are cost-effective for different climates and locations in the home.
Click here to go to our Calculator to understand the real R-value of a ceiling system or wall system with gaps in the insulation. It can get confusing when you see Imperial R-values in the USA, which is very different to Australia and Europe who use the metric system.
We will look into what does R-value means, how it is calculated, what are the minimum recommended values of R for attics, 2×4 and 2×6 walls, and so on (you will find a complete insulation R-value chart further on), and what it’s so important to pick building materials with high R-values.
27 lut 2022 · The R-values for specific assemblies like doors and glazing in the table below are generalizations because they can vary significantly based on special materials that the manufacturer uses. For instance, using argon gas in a double pane insulating glass unit will dramatically improve the R-value.

10 sie 2020 · This chart shows the approximate R-value per inch of various insulating materials but does not take into account any air leakage that can dramatically affect overall performance. Almost any type of insulation can improve your home’s performance. Some perform multiple steps simultaneously.
