U-value (thermal conductivity (W/(mK))
The thermal conductivity (U-value) describes how much warmth (watts/W) per metre (m) thickness per degree temperature difference (kelvin/K) flows though a component.
The lower the value, the less warmth is lost. In other words, good isolation is represented by a low thermal conductivity value.
Thermal Properties
- UFrame = 1.8 W/m2K (Meranti, Douglas Fir and Siberian Larch)
- UGlass = 1.6 W/m2K (24 mm Low E glass)
- UW = approximately 1.7 W/m2K
