CURBING AND FL AS HING
Outside of frame must be insulated with rigid type insulation;
We recommend a minimum of 20 mm t hick ins ulat ion (2-figure 7).
Check that the insulation is continuous, counter f lash and seal around the
frame
as shown in (1-figure 7).
CAUTION: To be effective, the upstream must end below the drop edge (3 - figure

Where pipes and electrical conduits extend through the roof, flashing must be
conformed to local codes of practice.
