PlastiSpan® HD Hydronic Insulation
For radiant floor heating systems

PlastiSpan® HD Hydronic Insulation is used in Commercial, Residential and Industrial applications.


PlastiSpan HD hydronic insulation is an expanded polystyrene (EPS)
insulation used as the insulation component in radiant floor heating systems.
Hydronic heating can heat your basement or garage floor, and melt snow
and ice from your walkways and driveways.

PlastiSpan HD Hydronic Insulation offers you ease of installation and a time
saving opportunity to help you install a radiant floor heating system.
PlastiSpan HD Hydronic insulation is your first component in this system to
minimize heat loss, allow uniform heat distribution to the floor area and
ensures the floor will be warmed faster. Different thicknesses of PlastiSpan
HD Hydronic Insulation and tubing are available for your project.

PlastiSpan HD hydronic insulation also incorporates supports for the
hydronic tubing. The supports ensure that hydronic tubing is held in
position until the concrete floor is placed. The hydronic tubing cast into
the concrete slab and PlastiSpan HD hydronic insulation beneath the
concrete slab ensures that heat is spread uniformly throughout the entire
floor area.

The closed cellular structure of PlastiSpan HD hydronic board provides
excellent resistance to moisture and the long-term insulating value is not
subject to thermal drift, because it contains no HCFC's or HFC's.

Hydronic heating can heat your basement or garage floor, and
melt snow and ice from your walkways and driveways.
