Heat Flux Testing

Heat transfer is a crucial factor in building energy efficiency; heat flux testing is used to determine the heat transfer coefficient (u-value) of a building component, such as a wall. The u-value would demonstrate how well the wall keeps the heat inside of a building, by measuring the heat flow through it.

Heat Flux Testing – disparities between theoretical and actual performance

A primary reason to undertake heat flux testing is to identify disparities between theoretical and actual performance. While thermal modelling can be used to determine the theoretical u-value of a building component, its actual in-situ performance can be confirmed using heat flux testing. Where there is any doubt regarding whether the calculated u-value matches the true u-value, this is considered the best practice approach.

Heat flux testing therefore helps to build up a more complete and accurate picture of heat loss parameters or – if used in conjunction with coheating testing – of whole-building thermal performance.

Stroma Tech undertakes heat flux testing to meet a range of requirements. All tests are carried out in accordance with the international standard ISO 9869, “Thermal insulation – Building elements – In-situ measurement of thermal resistance and thermal transmittance”.
