D Desiccant A hygroscopic substance used as a drying agent in insulating glass units. Dewpoint A calculated temperature at which water vapor will condense. Double glazing Two panes of glass enclosing a hermetically-sealed air space. Distortion An optical effect obtained … Continue reading →

Condensation When water vapour from the air comes into contact with cold surfaces, the vapour condenses on the cooler surface of the glass forming a foggy effect. Convection A transfer of heat by movement of air. Came A narrow flat … Continue reading →

B.T.U. British Thermal Unit Bead or Glazing Bead A strip of wood, metal or other suitable material attached to the rebate to retain the glass. Bevelling The process by which an edge of glass is finished to a bevel angle. … Continue reading →
