How to Use This Calculator

Enter Net Wall Area in sq ft and set Panel Length, Depth, and Panel Exposure Height in inches.
Enter Joint Width and Facade Height in feet — taller facades need more horizontal rail levels.
Set Waste Allowance to at least 12% — terracotta is fragile and installation breakage is common.
Review Panels to Order, Horizontal Rail (LF), Panel Clips, Total Weight (lbs), and Sealant Tubes.
Use Total Weight to confirm the structure can handle the dead load of the cladding system.

How the result changes with Panel length (in)

Wall area (sq ft): Net facade area to receive terracotta cladding.
Panel length (in): Length of each terracotta extrusion.
Panel depth (in): Depth (thickness) of the extruded terracotta profile.
Panel exposure height (in): Visible height of each terracotta panel after lapping.
Joint width (in): Open or sealed joint width between panels.
Facade height (ft): Total height of the terracotta-clad area.
Waste allowance (%): Extra for cuts, breakage (terracotta is fragile).

Identify Input Parameters
4 parameters
Wall area (sq ft) = 800, Panel length (in) = 24, Panel depth (in) = 1.25, Panel exposure height (in) = 8 = 7 input(s) provided
Calculate Panels to order
Panels to order = ceil(netPanels * (1 + wastePct / 100))
672 = 672
Calculate Total weight
Total weight = wallArea * weightPerSqFt
8000 = 8000
Calculate Net panels needed
Net panels needed = ceil(wallArea / coveragePerPanelSqFt)
600 = 600
Calculate Horizontal rail
Horizontal rail = numRows * approxWallWidth
1156 = 1156
