Abstract From the Canadian patent

A b s t r a c t, Pipe insulation comprising a number of substantially identical, annular bodies cut out in the shape of sheets from mineral wool, glass wool or similar fibre materials and having such a fibre structure that their compressibility is biggest in axial direction, said mineral wool bodies being put together around a common axis and wrapped in a resilient, crêpe-structured or pleated sheet material glued to the mineral wool.
