GRP Panel Design

PRE-Insulated Panel

By encapsulating a 25mm ~ 50mm layer of rigid polyurethane foam, POTAGLAS pre-insulated panel could maintain the desired water temperature stored inside the tank under extreme temperature condition. POTAGLAS pre-insulated panel could be selected for water storage where there is a need to stabilize the temperature against extreme heat or freezing conditions so to prevent dew formation.

*Flange height (FH) varies according panel series
*Standard colour: gray

GRP Panel Insulating Process

Potaglas insulated panel has achieved the consistent foamed rigid polyurethane layer with the lowest thermal conductivity by using the advanced PU injecting machine.

The insulated outer cover / skin is made of hot compression moulding process with the same material as used in the GRP panels which is resistant to ultraviolet radiation, weather-resistant and watertight.  It is fully complying to ADWEA (Abu Dhabi Water and Electricity Authority) – Guide to Water Supply Regulations.

Many insulation panels from other manufacturers often using thermoplastic ABS skin which is not suitable for severe weather situation.
