DEDUCTIONS AND EXISTING STOCK

Window reveal coating quantity — opening height scenarios.

How does changing opening height affect window reveal coating quantity when the other inputs stay fixed?

What this decision changes

A known internal space, existing stock or shared quantity must enter the correct subtraction or eligibility step rather than being counted as new material. Method basis: Measure the jamb, head and optionally sill returns separately from wall faces and convert them to coating containers. Reveal area = Σ(2 × opening height + opening width + optional sill width) × reveal depth × count.

The focus is opening height in the first repeated measured entry. Other repeated entries keep their own supplied values.

Evaluate your supplied alternatives

Start with your measured plan and selected product data. The initial values and range are illustrative. Each scenario changes only opening height in the first repeated entry; the other entered values stay fixed.

Read the evaluated results

Watch the net requirement and actual order separately. Invalid rows identify combinations that cannot satisfy the method's geometric or stock-basis constraints.

Replace every illustrative baseline measurement and selected product value with the inputs for your actual task.
Enter a comparison range on the focused input's stated unit and quantity basis.
Review rejected combinations and use the exact detail lines to distinguish measured demand from whole purchases.

Keep the comparison within scope

The supplied cavity, exclusion or stock eligibility must already be valid; the result does not select a safe shell, opening or construction detail.

Counts the arithmetic consequences of supplied specifications. Does not select construction systems, structural properties, fastening schedules, safe handling limits or code compliance.

Only the listed samples are evaluated. Intermediate values, alternate constraints and global cutting optimality are not inferred from the graph.
