The insulation apparatus comprises: a fire reflecting coating 110 formed on a first surface of a fire resistant layer 105; an intumescent layer 115 formed on the opposite surface of the fire resistant layer 105; a sound abatement layer 125 formed over the intumescent layer 115; and means for attaching the apparatus to an object, formed over the sound abatement layer. The preferred insulation apparatus also includes non-woven, insulating, sound abating and fire protecting layers 120, 130; the inner of which separates the intumescent layer 115 from the noise reducing layer 125; the outer of which, 130, separates the acoustic layer 125 from a polyurethane coated (to aid adhesion) woven fabric 135. The preferred fire resistant layer 105 comprises woven mineral (for example, basalt) fibres. The preferred reflective coating 110 comprises a polymer (for example, silicone) containing reflective (for example, micronised Aluminium) material. The preferred intumescing layer contains intercalated graphite (in, for example, a polymeric binder). The preferred acoustic membrane 125 comprises heavy salt. The apparatus is formed into a plurality of pockets that are preferably sewn or buttoned up. The apparatus is used around the engine of a passenger vehicle.
