In use, the liner is flexed about pivotal axes parallel to and between the grooves and the back face of the block. The flexed liner can form a tube with the coated front face exhibiting concave curvature in a plane perpendicular to the pivotal axes. The tube can be inserted into a gas transfer duct.

[ What is claimed is:] [1.] An insulation sheet comprising:a rectangular central block of insulating material, the block having a first major dimension and a second major dimension together defining a front face and a rear face in parallel planes distant by a thickness; the block further having a plurality of grooves penetrating the front face to a floor at a depth less than the thickness and extending parallel to the second major dimension, the grooves being spaced apart from other grooves in the first major dimension direction and running the length of the second major dimension, each of the grooves having side walls which intersect with the front face to form opposing contact edges separated by a gap; anda contiguous barrier layer of an elastically deformable substance bonded adjacent to the front face, wherein the barrier layer is coextensive with the front face and bridges the gaps between opposing contact edges.
