GYP-SPANŽ Radiant
GYP-SPANŽ
Radiant is a gypsum concrete floor underlayment designed
specifically for use over radiant heating systems. It
encases the tubes or cables without air bubbles, creating a
superior thermal mass that provides uniform heat transfer.
GYP-SPANŽ Radiant floor underlayment is the energy efficient
and cost effective way to create a smooth, flat, evenly
heated floor surface for the attachment of virtually any
finished floor covering.
