effective width - coverage width of panel, indicated in mm
Total width - total width of the panel, indicated in mm
Length min - minimum panel length (in mm), specifies the minimum length of the sheet
Length max - the maximum length of the panel (in mm), defines the maximum length of the sheet. For sheets exceeding the maximum length, another sheet of panel will be added vertically** Lap (mm) - specifies the length of the overlap when sheets are joined vertically. If a negative overlap value is specified, the programme will apply an expansion joint between the sheets.
Direction of vertical joint - sheets laid from the top (ridge) or bottom (eaves) of the roof - applies when Mounting method is specified horizontally.
Horizontal installation direction** - sheets to be installed from left or right - applicable when installation method is specified vertically
Starting edge [mm] - a value in the parameters defining the bottom margin of the coverage (0-flat)** Length rounding - specifies the precision of the length calculation (in mm) 1 to one mm, 10 to a centimetre, 50 to five centimetres
Upright laying - the method of laying sheets when the length of the slope exceeds the maximum length of the sheet. Selectable from largest - the maximum length sheet will be applied from the bottom and then the sheet with the missing length. proportionally - the sheets will be of equal length verticallyMethod of installation - vertically (from eaves to ridge), horizontally** Alternate joint [mm]** - value in mm specifying the aplitude of the difference in length of the sheets for even and odd strips when joining the sheets vertically
** Minimum pitch [°] --minimum roof pitch for the application of the stated covering (informative value)
