Cellular glass insulation.

Cellular glass insulation from FOAMGLAS has gone underground to ensure that Guernsey's lights stay on.

The island of Guernsey is partly dependent on heavy fuel oil for its power generation. The oil has to be imported by ship and taken 1/2 km by pipe along the docks and local roads to the power station.

This gives three potential problems: the oil needs to be heated to keep flowing, the pipe has to be buried, and corrosion failure is an ever-present risk.


Pittsburgh Corning UK Ltd says -

FOAMGLAS helps prevent Corrosion Under Insulation.

There has been pipe failures in the past and so it was critical that the pipe was protected against all possible causes of failure including corrosion. In addition to anti-corrosive paint coatings on the pipe, cathodic protection was specified. This meant that no metals were allowed around the pipe and so a non-metallic coating, Terostat, was factory applied to the FOAMGLAS.

FOAMGLAS prevents fire hazards.

Trace heating temperatures meant that plastic foams were unsuitable due to the risk of scorching. FOAMGLAS cellular glass insulation will not scorch or burn.

FOAMGLAS buried under access roads.

Burial under roads and docks meant that a load bearing insulation was required. FOAMGLAS has exceptional compressive strength and so is ideal for buried applications.
