Patent ID: 6921564

Claim:
A part-cylindrical pre-formed insulation module for insulating a component including: an unstriated insulation layer with an inner surface for contacting an outer surface of the component to be insulated and comprising insulating material having fibres substantially in contact with one another throughout said insulating material and entirely sealed over said inner surface by a sealing agent, said fibres having no specific orientation relative to the module within said insulation layer, said insulation layer being substantially uniform in composition and density over a cross section thereof, said insulation layer including an outer surface and contacting surfaces; a substantially non-fibrous, resilient cladding layer shaped to the component to be insulated and directly adhered to the insulation layer at the outer surface thereof; and connection means disposed along the length of the body for hingelessly connecting with at least one further adjacent insulation module wherein said insulation and cladding layers of said module are disposed relative to each other such that, on connection to said further insulation module, insulation layers of said module and said at least one further module are brought into contact along said contacting surfaces of the insulation layers of the modules for insulating at least a portion of the component.
