R-value calculator
Check the U-value and building physics of your planned structure with U-Wert.net and LIGNATUR.
Below, you will find the link to ubakus.de, tailored to your configuration. By selecting «Use demo version» you can view the configured structure. Commercial use is permitted by u-wert.net GmbH with a paid premium subscription. We highly recommend the cost-effective options for your office.
The visualization of your selection in the image on the right is simplified and does not consider the element height.
