Abstract: Turbine insulation is disclosed, and comprises blankets, ribs and coupling members. The blankets define, with the turbine, an annular channel in receipt of the turbine vertical joint and a pair of longitudinal channels each in receipt of a respective turbine horizontal joint. A pair of ribs are positioned in each longitudinal channel, in volume-filling relation thereto and overlapping the blankets disposed, respectively, fore and aft of the vertical joint. A pair of ribs are positioned in volume-filling relation to the annular channel and overlapping the blankets disposed, respectively, on the upper and lower arcuate portions of the housing. A coupling member is positioned in each longitudinal channel at its intersection with the annular channel, in volume-filling relation to a void defined by the housing and the ribs and in lapped relation to the ribs.
