The use of curtain walling demands a different approach to rain arrestment.
Where the window and door surrounds project forward of the finished front face rather than being set-back, extended provision must be made to prevent the projection through the curtain walling from acting as a bridge via which wet might track inwardly.
The use of preformed moulded protective DPC trays provides the answer.
Positioned behind the curtain walling and moulded to encapsulate each opening horizontally and vertically, the trays arrest any water entering panel breaks and direct it to drain into adjacent baffles between panels.
These in turn permit all water to gravitate in the usual way and discharge at the intended lower levels.
