This web page calculates insulation R-values for whole floor, wall and roof constructions based on insulation R-values and the selected construction type.
18 lut 2014 · Once changes are made, the calculator updates R-values and costs. A team of software developers is offering a free online calculator you can use to compare the thermal performance and cost of a variety of roof, floor, and wall assemblies.
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. Click to launch the Effective R-Value Calculator.
R-value means the thermal resistance (m2K/W) of a material calculated by dividing the thickness by its thermal conductivity. Total R-values are based on the sum of all components of the building system including indoor and outdoor air-films, building materials used in the system and air-spaces.
Ekotrope’s Free Calculators. Our calculators allow you to compute the R value (or U Factor) of your assembly. Ekotrope also offers full home modeling tools to industry professionals and universities to support IECC code compliance, LEED for Homes, ENERGY STAR, 45L, etc.
