The insulation core of the panels can provide high levels of thermal performance out-of-the-box. This is measured through a U-value. Put simply this is a measure of how well a building element (this means a complete floor, wall or roof) can prevent the most common types of heat transfer. Building elements with lower U-values are more effective at preventing heat loss and so better insulated. You can learn a little more about U-values in the video on the left.
The core of TEK panels has a thermal conductivity of 0.024 W/mK. The OSB/3 facings have a thermal conductivity of 0.13 W/mK.
Which means?
A lower U-value indicates better insulation and thermal performance, meaning less heat is transmitted through the material or assembly. Therefore, in terms of energy efficiency, lower U-values are desirable because they mean reduced heat loss during cold weather and reduced heat gain during hot weather.
