<p>A flexible thermal insulation panel (9, 21) comprises a block of consolidated particulate microporous insulation material (7, 19) enclosed in a porous envelope (1, 15). The block is bonded to the envelope by compression of the envelope to cause penetration of particles of insulation material (7, 19) at the surface of the block into pores of the envelope. The envelope (1, 15) comprises a stretchable material, at least in part. The consolidated block and the stretchable material of the envelope bonded thereto can be conformed to a non-planar surface with the stretchable material of the envelope remaining bonded to the block. <IMAGE></p> |
