U-value, R-value, humidity, and surface temperature measurements made easy

The gO Measurement-System is a cloud-based, wireless system for U-value, R-value, surface temperature, and humidity measurements. You can measure simultaneously with up to 16 sensors and remotely monitor the measurements in real-time. It is the only system on the market which gives you hard data about the insulation quality of building elements. The gOMS is especially designed for applications in building physics.

What is the u-value and why is it important?

The u-value describes the insulation quality of a building element, for example of a wall. It is the most important value for user independent assessments of a building's thermal performance: the lower the u-value, the better the insulation. Furthermore, quantitative assessments of heat bridges are possible, for example to detect sources of mold.

Typical use cases

Assessing the status quo

A precise status quo assessment of the U-value before a refurbishment increases the quality of the overall planning.


Check before project handover

In case of dispute between project partners, a non-invasive U-value measurement can increase the transparency between the project partners.

Resources: Case studies, white papers, and FAQ

Below you find a list of case studies and white papers about various U-values projects conducted by greenTEG, our customers, and project partners. Please note that the measurements discussed in these resources were made with the gSKIN® U-Value Kit, the preceding model of the gO Measurement-System. The measurement principel with the gO Measurement-System remains the same. Contact us if you have any questions.
