Flashings For Vertical Cladding

Window and door flashings for vertical cladding are similar to those used for horizontal cladding, a cavity is, however, not required for vertical cladding.

The main difference is that the module is running horizontally and therefore some flexibility is required if the flashings are to be equal on both sides. To provide for this the trimming size of the window opening should be plus half the module dimension. The under lap of the profile should be flattened as shown in drawing 6.4.4.B.
