Evacuated glass windows
WebThe gap is evacuated, eliminating conduction and convection across the gap. Small cylindrical pillars, each L = 0.2 mm long and D = 0.20 mm in diameter, are inserted between the glass sheets to ensure that the glass does not break due to stresses imposed by the pressure difference across each glass sheet.
