The R-value of an unfilled 8" x 8" x 16" CMU is 1.11. This includes two 4" x 4" x 8" spaces on the interior of the block. The R-value of this ambient space is 1.00—any space from ½ inch to four inches has a value of 1.00. This means that the R-value of the actual concrete block is a paltry 0.11. Will Cement in the Center Raise R-Value?
The methodology for this calculation is described in The Mass-Enhanced R-value of Precast Concrete Sandwich Panels – an Industry Standard. This document, authored by Prof. Williamson, allows the high …

Attachments/webing is not standard, read closely Post and beam-> not for me High R-value is obtain in two ways, 1) post and beam means less concrete=> more . 2) Higher R for this , but not so much. As an alternitive, High R-values can be obtained by using Quad-loc(sp?) Or attaching additional to a common block. Patrick T
R-values change depending on where in the country the building is taking place, ranging from 1.5 to 3.0; Meeting the required R-value is harder, with additional insulation required.

The table below provides a general idea of the R-value for various thicknesses of normal concrete slabs: R-value of 1 inch of concrete: 0.08. R-value of 4 inches of concrete: 0.32. R-value of 6 inches of concrete: 0.48. R-value of 8 inches …
Smart Shop, you're missing the point on the R-values. The R-values you're quoting are false. The reason we know that they're false is that the material has much lower R-value than pure . There is no "R21-ish" 8-inch block of EPSCrete. It doesn't exist. You've got to wrap your head around the fact that EPSCrete isn't an insulation material.

This site is all about DIY uses of EPScrete and the many things that can be built with it. Along the way I will compare epscrete to aircrete and other alternative building methods. I intend to build my next house out of epscrete and I will show how it is constructed. More importantly I will discuss why I am using epscrete blocks and panels.
modern day large-scale produced cement known as the Pozzolanic Portland Cement (PPC). EPS is a green building product because it is used as insulation, which improves a building's energy efficiency. EPS is shown to have a long-term, stable R-value. A 2009 national study found that EPS provides a substantial reduction in greenhouse gas emissions

In general R Value is a "fudged" method that was designed for fiberglass insulation – not for other types of insulation. Scientific studies and European countries use: thermal conductivity measured in W/m.°C. It should …
I am seeing that air entrained concrete has a higher R-Value than standard poured concrete (see below). Whereas it makes sense, the difference surprises me. Is air-entrained concrete really this good at insulating? Standard Concrete: R = 0.8 (F*h*sqft/BTU)/in Air Entrained Concrete: R = 3.9 (F*h*sqft/BTU)/in
Mass enhanced R-value for Sandwich Panels. What is special about the Sandwich Panel R-value Calculator is that for the first time ever you can calculate a Mass-Enhanced R-value for a sandwich panel wall. The methodology for this calculation is described in The Mass-Enhanced R-value of Precast Concrete Sandwich Panels – an Industry Standard.
Concrete R-Values In general, low-density concrete has a higher R-value than high-density concrete. The type of concrete used for floor slabs typically has an R-value of 0.1 to 0.2 per inch of thickness, meaning a 6-inch-thick …

Answer: The R-values in the table above, based on data from the 1993 ASHRAE Handbook (American Society of Heating, Refrigeration, and Air-Conditioning Engineers), are for 6-inch-thick concrete walls of differing densities.ACI 213R-87, "Guide for Lightweight Structural Aggregate Concrete," divides lightweight concretes into three categories.

Let's translate this to a square foot of wall space for a better understanding. If we consider an average R-value of 3.5 per inch for Hempcrete (a mean value between 2.4 and 4.8), a Hempcrete wall of 12-inch thickness would provide an R-value of 42 per square foot (3.5 R-value/inch * 12 inches = 42 R-value).
Cast-in-place concrete typically has an R-value ranging between 0.08 and 0.10 per inch, similar to other types of poured concrete. The specific R-value can vary depending on factors such as the mix design, curing conditions, and aggregate used.
