Window and opening materials.
Measure each pane, opening perimeter and reveal depth. Keep trim margins separate from the finished dimensions.
Gather the selected product data
Record film roll width and length, directional restrictions, gasket roll length and specified flashing allowances.
Choose the matching calculation

Fit identical whole-pane film blanks in a roll, preserving trim allowance and permitted film orientation.
Glazing Gasket Perimeter Loop Order Calculator
Keep separate opening perimeters intact when cutting gasket rolls, or pool length only under your permitted joint plan.
Window Opening Flashing Strip Cut Order Calculator
Order continuous sill, jamb and head tape strips from supplied opening measurements and detail extensions.
Window Reveal Coating Quantity Calculator
Measure the jamb, head and optionally sill returns separately from wall faces and convert them to coating containers.

Keep the estimate within scope
Rotation must be permitted by the product. Film suitability for a particular glazing assembly is outside this calculation.
