Insulation Panel Go to see panel :

Insulation performance of panels (Kcal/m2-h-°C)

K value for warehouse law is determined by overall coefficient of heat transfer (Kcal/m2-h-°C)
[Coefficient of heat conductivity or insulation (Kcal/m2-h-°C)/thickness of insulation (mm)]

Core thickness
K value
Temperature Range
Thickness if replaced by Styrofoam
42 mm 0.42 +10°C – (-5°C) 75 mm
75 mm 0.24 (-5°C) – (-25°C) 125 mm
100 mm 0.18 (-25°C) – (-35°C) 178 mm
125 mm 0.14 (-35°C) – (-45°C) 213 mm

- Temperature range is the reference value. Calculation of economical panel thickness depends on size and intended use.
- Coefficient of treat conductivity (Kcal/m2-h-°C) :Rigid polyurethane foam = 0.018 Styrofoam = 0.03

- Compared with the other types of panels, this type of panel is low-priced.
- Highly effective in heat insulation.
- Compared with the other typed of panels, this type of panel can be a longer panel.
- The sillicon-base sealer will be used for the panel joint sections to ensure excellent air-tightness.
- The component of this type of panel is the self-extinction type foam (class SE).
