Pre-formed pipe sections

Half-shell sections (stone wool, glass wool, calcium silicate, PIR for cold) sized to standard pipe ODs, snapped on and banded — fastest straight-pipe insulation there is.

Where it belongs

When this is the right system

Straight runs of standard pipe sizes. One fitter, no fabrication, consistent thickness — but dead-ends at every valve and flange (where removable covers take over).

Standard: ASTM C547 / C585 (dimensions) / EN 14303.
