LAYERED MINERAL FIBRE ELEMENT AND ITS METHOD OF MANUFACURE

摘要

An insulating element is provided in the form of a substantially flat mineral fibre batt which has first and second major surfaces wherein the first layer is a high density highly bonded layer and the second layer is a thicker lower density less bonded layer, optionally with an intermediate layer between the first and second layers. The second layer, and the intermediate layer if present, are both much softer than the first layer and this allows the flat batt easily to be conformed around an appropriate pipe or tank, with the first layer outermost.
