Project Estimator

Add rooms and windows as needed. SigCalc calculates each opening, keeps a running total of glass area, and estimates the installed project price from your entered cost per square foot.

Project details

Film name is for reference. Installed price per square foot is used to calculate the project total.

Total glass area
0.00sq. ft.
Total installed cost
$0.00

Customer Proposal

Choose how square footage appears on the customer proposal.

Glass area = Height (in.) × Width (in.) ÷ 144 × Quantity. Total installed cost = Total glass area × Installed cost per sq. ft.

Rotation is allowed. SigCalc first tries to keep each opening in one piece, then uses seams only when the selected roll width requires them. Choose how seamed openings are divided. Seamed pieces stay sequential at Roll Side A; installed orientation alternates A/B, B/A, A/B. Verify matching cross-web seam edges before cutting. Offcuts are reused automatically when another cut fits.

Waste is film pulled area minus installed glass area; remaining unpulled inventory is not project waste. Cut dimensions include the selected oversize allowance. Layout is an optimized cutting plan, not a substitute for field verification. Confirm glass sizes, film orientation requirements, seam placement, and available roll inventory before cutting. IMPORTANT: A/B orientation labels are preliminary; for multi-piece seams verify the exact matching cross-web positions of mating edges before cutting. A slitter may be required.
