Total R-Value calculation This method of calculating Total R-Value is as outlined in New Zealand Standard (NZS) 4214 ‘Methods of determining the total thermal resistance of parts of buildings’. In general, the R-Value of a material is determined by dividing the thickness of the material (in metres) by the thermal conductivity (in W/m.K).

The R-Value calculator is best used as follows: Work out all the different materials and surfaces that make up the wall/ceiling or surface you want to work out the R-Values and U-Values for. Remember the horizontal or vertical orientation of the material is important to get its insulation value correct. Remember to take into account any air ...

R0 Calculator Welcome to the R0 Calculator R0 is a term commonly used in epidemiology that helps to describe the rate of infection of a disease. What is R0? (R Naught) In epidemiology, the basic reproduction number or R0 (pronounced “R nought”) of an infection can be thought of as the expected number of cases […]

The selected R-value will be automatically transfered into the currently selected cell of the construction calculator. If insulation is compressed its R-value is reduced by its compression. Example: Insulation with R-2.5 is compressed from 94mm to 78mm, i.e. 17%. Therefore its R-value is reduced by 17% to R-2.1.

29.11.2017 · R-value is a measurement that rates how resistant a product is to heat flow, measuring the ability of heat to transfer from one side of an object to another. Our calculator helps you measure what r value for exterior walls you may be looking for, as well as for different applications. i.e. ceiling insulation R value, R value for walls and more.

R-value, commonly used when describing walls, roofs, and similar housing components, measures how well building insulation can prevent the flow of heat into and out of the home. A higher R-value equates to greater insulation performance, and thus higher savings on heating and cooling.
