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.
This web page calculates insulation R-values for whole floor, wall and roof constructions based on insulation R-values and the selected construction type.
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.
12 wrz 2023 · How to Find the R-Value of a Roof. To calculate the total roof R-value, find the total thickness in inches of each type of insulating material within the roof system. For each different material, multiply the thickness in inches by the standard R-value per inch for that material.
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.
This version of the calculator is for small and medium-sized facilities that purchase electricity without a demand charge based on peak monthly load. To compare two non-black roofs, print out results of separate estimates for each vs. a black roof.
R-Value is a measure of insulation’s ability to resist heat traveling through it. The higher the R-Value the better the thermal performance of the insulation. The table below shows what levels of insulation are cost-effective for different climates and locations in the home.
