Thermal Performance

 The graph shows the total energy demand in various parts of the country. Using these three different materials:

• Two Core
• Steel Stud
• Wood-Framed

Description of Property

• Specific Heat Capacity

• c - (kJ/kg·K)

•  The amount of energy (heat) that is required to increase the temperature of one unit of its mass (kilogram) by one degree. If the wall requires a lot of energy to raise its temperature by one degree throughout its mass, then heat transfer through the wall will be at a minimum. 

• Thickness

•    - (mm)

•  The thickness of a wall will reduce heat transfer and will also leave a larger margin for utilities running through the wall.

• Thermal Resistance

• R - ((m2·K) / W)

•  The ability of the wall to resist fluctuations in temperatures between outer and inner surfaces.
