EFYOS BLUE SMART A on industrial roofs. Setting out falls to outlets
PIR insulation
Order EFYOS BLUE SMART A boards from the falls plan. Start at one outlet. Mark its catchment boundary, outlet level, high points and the direction in which the boards increase in thickness. An area of identical size can need different tapers when the outlet is closer to the edge. List codes and quantities separately for each catchment. If the installer moves an outlet, this makes it possible to check the extent of the change, revise the schedule and identify which crews need the new drawing.

Catchment boundaries
Draw runoff arrows on both sides of each change in roof slope. Use a key that distinguishes water flow from the direction of increasing PIR thickness.
Pack markings
Survey from the outlet body to the watershed with the next catchment. Take intermediate deck levels as well. A local step can change the finished profile even where the tapers are in the correct order.
Rise across four boards
The 1200 × 1200 mm elements have a nominal fall of 2.08%. The data sheet distinguishes standard boards 1–8 from the differently shaped A1–A8 and B1–B8 elements. Include the letter in every plan reference.
Over 4.80 m, a constant 2.08% gradient gives a height difference of about 100 mm. Add this rise to the surface level at the outlet to obtain the level at the high end. Include the specified layer beneath the tapers.
Moving an outlet
If the outlet moves, recheck the length of each run leading to it. Establish whether the boundary with the next catchment moves too. Assign the revised plan to the relevant packs.
Checks before waterproofing
Before laying the membrane, compare the board markings with the plan and check levels at the outlet and changes of slope. A photograph with a measuring staff helps explain any local depression later.
One kit per outlet
Label pallets with the outlet number and schedule revision. For partial deliveries, list the missing tapers so a similar-looking board from the next area does not get used in their place.
A plan for the building manager
After inspection, enter the as-built outlet positions and catchment boundaries on the plan. When a new plant base is proposed, the building manager can check whether it crosses a drainage path.
