UVAL Wired System

UVAL Wired is a calibrated and plug-and-play solution that allows you to measure the thermal transmittance of a material or assembly for the building industry.

Our measurement approach uses a heat flux sensor and two temperature sensors. This method is standardized in ISO 9869, ASTM C1046, and ASTM C1155. It is a proven method that delivers reliable quantitative in-situ U-Value information of a building envelope.

Frequently Asked Questions

Didn't find what you're looking for? Feel free to send us an e-mail or book a meeting with our expert.

Can I take the U-Value of glass?

Both of our system models feature a CSV export function, enabling comprehensive analysis of measurements. We also provide an adaptable Excel template upon request, which you can use to further tailor and analyze your data.

What interior building conditions should I watch out for?

The following conditions can affect readings: 

  • Proximity to Heating and AC Devices
  • Room Occupancy
  • Drafts
  • Mold Presence
What exterior building conditions should I watch out for?

Direct sunlight should be avoided on the sensors. greenteg’s node and outdoor sensors are rated IP67.

What's the minimum period for an ISO calculation?

72 hours, however ideally you need at least 96 hours
