The BTS U-Value Measurement System is a portable tool which is used to measure the thermal transmittance of building elements, helping to identify potential insulation upgrades and to reinforce investment decisions.
The rate of thermal transmittance (U-value) through individual building elements contributes significantly to the overall energy efficiency of a building. The lower the U-value of an element of a building’s fabric, the more slowly heat is able to transmit through it, and so the better it performs as an insulator.
Our system is a complete kit for measuring U-values that includes two heat flux plates, surface temperature sensors, internal/external air temperature sensors, a data logger and a 4G modem.
The system can record measurements over a number of days or weeks in order to deliver greater accuracy and quantify the in-situ U-value of a building envelope according to the ISO 9869 methodology.
