A matrix disc for a rotary regenerator heat exchange apparatus includes a pair of spirally wound sheets, a first sheet having a continuously formed sinusoidal corrugation having a pitch dimension that accomodates thermal expansion in the strip. The first sheet is juxtaposed against a second corrugated sheet having a plurality of axial spaced corrugated segments therein having a pitch to accomodate thermal expansion and wherein each segment is interconnected by a plurality of elements including flat side wall segments having an axial length greater than the pitch dimension of abutting corrugation of the adjacent first strip and including a diagonally directed segment therebetween to space the corrugated segments of the second strip away from the first strip to define a plurality of generally rectangularly configured air form fluid flow paths in the matrix disc.
