ISO Calculator

Plan pallets and truckloads for your tapered and flat ISO insulation orders in seconds.

Details

Enter pieces for each tapered panel letter (AA, X, Q, etc.) or squares for flat ISO, and the tool will total your 4×4 pallets, 4×8 pallets, and full truckloads as you type. Built for Roofers Mart contractors, warehouse staff, and sales teams.

How to use it
  • Tap a slope section (1/8″ per foot, 1/4″ per foot, 1/2″ per foot, etc.) to expand it.
  • Enter the piece count next to each panel letter. Piece counts come from the manufacturer’s loading chart for your specified panel code.
  • For flat ISO, expand the Flat ISO Board section and enter your square count for 4×8 or 4×4 boards.
  • Totals update automatically at the top of the calculator (truckloads are based on 48 4×4 pallets per truck).
  • Hit Clear to start a new estimate.
