Hi I am trying to complete my LEM calculator for a LEED V4 healthcare project. This feels like a silly question.

  1. Carlisle 725TR Air and Vapor Barrier. This is a composite sheet membrane. How would I measure the amount I used on my project in liters?
  2. Carlisle Densdeck Prime Roof Board. This is an insulation board. How would I measure the amount I used on my project in liters?
  3. Dimensional plywood. How would I measure the amount I used on my project in liters?
  4. Carlisle InsulBase Insulation used with EPDM Roof. Same question.
  5. Carlisle SureWhite EPDM Roof. Same question.
