Ardex FLEXBONE UH 905 Floor Heating and Uncoupling Membrane Sheet, 8.4 Sq Ft

ARDEX Floor Heating Heat Sheet – UH 905

The ARDEX Floor Heating Heat Sheet for use with ARDEX UH 905 is a purpose-designed underlayment layer that supports and secures electric radiant floor heating cables during installation. The heat sheet provides a stable, uniform base that helps keep heating cables properly positioned while the self-leveling underlayment is poured.

When used together with ARDEX UH 905, this system creates a smooth, fully encapsulated heating layer that improves heat transfer, reduces the risk of cable movement, and delivers a flat, durable surface ready for tile, stone, LVP, or other floor finishes. The combination ensures consistent warmth across the floor while minimizing cold spots and improving overall energy efficiency.
