  1. R-1.9 to R-2.5
    Yes, concrete blocks do have an R-value. An 8-inch thick block wall with no other insulation has a thermal resistance rating ranging from R-1.9 to R-2.5, depending on the density of the blocks. R-value is a unit that measures the resistance to heat flow.

    What is the R value of a concrete block wall?
    Concrete block wall with air in cavities = R 2.0 Concrete block wall with Perlite in cavities = R 2.9 The reason that it is important to make a good estimate for the current R value for uninsulated spaces is that small changes in R values result in large changes in heat loss when the total R value is low.

    What is a good R-value for a concrete wall?
    Concrete has an R-value of between 0.1 and 0.2, but when combined with the built-in EPS foam, Fox Blocks boast an impressive R-value of 22. In addition to providing strong walls, ICF walls achieve such high R-values because of the different construction methods.

    What is a typical R-value for a concrete block?
    The typical R-Value in Figure 2 (a) and (b) is for 90 mm dense weight concrete block. The typical R-Value in Figure 2 (c) and (h) is for 140 mm dense weight hollow concrete block. The typical R-Value in Figure 2 (d) is for 125 mm solid reinforced concrete (2400 kg/m).

    What is a typical R-value for 125 mm solid reinforced concrete?
    The typical R-Value in Figure 2 (d) is for 125 mm solid reinforced concrete (2400 kg/m). The Total R-Values in this Figure are for external walls. The Total R-Value for an internal wall of the same construction would be 0.08 greater because the R-Value for an outdoor air film would be replaced by that of an indoor air film.

    What is the R-value of concrete?
    Thermal insulation increases and density decreases, meaning that concrete with a lower density has a greater R-value than concrete of a higher density. Typically, the type of concrete used for floor slabs has an R-value of 0.1-0.2 per inch of thickness. Looking for high-quality concrete for your projects? Get in touch today

    How do you increase the R value of a building?
    The Total R-Value of a form of construction may be increased by the amount that an individual item is increased. The addition of 10 mm of render to a concrete or masonry wall will increase the Total R-Value by 0.02. The typical R-Value in Figure 2 (a) and (b) is for 90 mm dense weight concrete block.
