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)]

Remarks
- 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).
