ABSTRACT:
An object such as a fuse is enclosed within a homogeneous block of microporous thermal insulation material by a method which includes forming first and second blocks of insulation material having a relatively low density, arranging the object between co-operating faces of the blocks, and compacting the blocks around the object so as to cause the blocks to merge and to form a homogeneous block of microporous thermal insulation material having a relatively high density. The first and second blocks may be incorporated into first and second housings respectively, one of the housings being provided with a protruding tab and the other of the housings being provided with a corresponding slot.
