a) Determination of dimension A (Bottom flashing batten)
The « C » dimension is the Minimum batten width necessary to
avoid reverse slope on the bottom flashing. It’s possible to use a
wider batten, this will simply raise up the PV field.
2) Calculation of the overall height of the installed system
b) Determination of dimension H
Dimensions of Easy Roof system

H
= Step x (
