Gypsum, Drywall & Interior Panel Manufacturing calculator
Paper Facing Consumption Calculator
Estimate paper liner consumption by entering boards to produce, liner area per board in sq ft, and liner feed efficiency. The result sizes the roll order and accounts for splice waste and spool-end losses so you do not short the spool cart.
What this calculator does
- Estimate paper liner yardage needed for a board production run based on boards to produce, liner area per board, and liner feed efficiency.
- Use it when ordering face and back liner rolls before a production run to avoid a roll shortage that forces a mid-shift splice and causes board line downtime.
- The result estimates the paper liner area in sq ft needed to complete a board run at the entered liner area per board and feed efficiency.
Formula used
- Theoretical liner = boards to produce x liner area per board
- Required liner = theoretical liner / liner feed efficiency
Inputs explained
- Boards to produce: undefined
- Liner area per board: undefined
- Liner feed efficiency: undefined
How to use the result
- Use it when placing a liner roll order, planning spool cart inventory, or reviewing liner loss against a formulation target.
- It remains an estimate when liner width, roll diameter, splice frequency, or board width changes from the values entered.
Common questions
- What is paper liner in drywall manufacturing? Paper liner, also called facing paper, is the kraft or manila paper sheet bonded to the face and back of a gypsum board to provide strength, surface quality, and printability. It is fed from large rolls and must be sized correctly for the production run.
- What data should I enter? Use boards to produce from the production schedule, liner area per board from your board spec or formulation sheet, and feed efficiency from recent splicer performance records.
- When is the result only an estimate? It remains an estimate when board width, liner roll width, splice waste, or spool-end loss differs from the values entered.
- What decision can this support? Use the result to set the liner roll order or spool cart quantity, then confirm with the production planner and liner supplier lead time before committing the run.
