Probably one of the most
unusual applications for
Raychem’s IceStop selfregulating
roof and gutter
de-icing system, Dunster
Castle relies on the system to
protect its new lead roof.

Not only can the melting
and refreezing of ice and
snow cause damage to roofs
and gutters, but heavy icicles
may fall and cause injury.

Jointing Technologies of
Bristol installed the roof and
gutter de-icing system which
provides drain paths for
roofs, gutters and downspouts.

The self-regulating heating
element in the heating cable
consists of a continuous core
of conductive polymer
extruded between two copper
bus wires.

As current flows through
the core, the heating cable
regulates its own heat output
in response to ambient
conditions, eliminating
hotspots and achieving
efficient temperature control.

The cable’s parallel
circuitry allows it to be cut to
the exact length required, so
there is no wasted cable.
