XPVC vs. PVC

[jason_ladouceur]

XPVC is actually what you want and what mostly everybody uses. It is also generally cheaper than regular PVC. XPVC stands for Expanded PVC. All the big names like reptile basics use XPVC.

Expanded PVC has a cellular core much like styrofoam insulation. It's half the weight of rigid PVC and provides a level of insulation that rigid pvc does not.
