GRP PRE-INSULATED PANEL

By encapsulating a 25mm ~ 40mm layer of rigid polyurethane foam, PIPECO pre-insulated panel could maintain the desired water temperature stored inside the tank under extreme temperature condition. PIPECO pre-insulated panel could be selected for water storage where there is a need to stabilize the temperature against extreme heat or freezing condition so to prevent dew formation.
