For instance if you have a material with an R-value of 12 attached to … WebbThe 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. huda beauty sign up
