ABSTRACT:
Structural sections comprising two spaced apart parts defining an intervening evacuatable void, the parts affording a high degree of thermal and acoustical insulation due in part to the vacuum but also to the minimal contact between the two parts. The parts are held apart against atmospheric pressure through the use of line or point contact formed in a particular manner to minimize thermal and acoustical conduction at the contacting surfaces.
