SOPREMA EFYOS BLUE A on a large roof. Planning the parapet junction
PIR insulation
When specifying EFYOS BLUE A on an industrial roof, measure from the finished membrane to its termination at the parapet. Clearance can be tightest where the roof rises, even if the parapet stays level. Compare those sections before grouping stretches of the perimeter under one detail. Increasing the PIR thickness from 100 to 120 mm changes both thermal resistance and membrane level. Assign each board thickness to a roof zone on the order. Show the space for the waterproofing upstand and coping fixings on the drawing.

Mapping the roof perimeter
Mark corners, steps and changes in fall on the roof plan. Put the section number beside the corresponding length of perimeter so the roofer can identify it from the roof itself.
Reading the BLUE A data sheet
At each step, record the deck and the underside of the proposed coping against one datum. Include the full build-up and the rise due to falls. This schedule gives the available parapet height at each location.
What another 20 mm changes
The PIR core has a 50 µm aluminium facing on each side. The data sheet gives λD of 0.022 W/(m·K), CS(10/Y)120 and reaction-to-fire class E. For profiled edges, check the cover dimension before counting rows.
Declared RD is 4.50 m²·K/W at 100 mm and 5.45 m²·K/W at 120 mm. With the deck and all other layers unchanged, the 120 mm option leaves 20 mm less height for the parapet junction.
A section at the high point
If clearance at the upper end of a fall is insufficient for the detail, mark the surveyed levels on a section for the designer. The solution must accommodate the membrane termination and the shape of the coping.
Inspecting the first corner
Before fitting the metal coping, inspect insulation and waterproofing continuity at the corner. Measure the vertical upstand from the finished membrane and compare it with the approved detail for that location.
Scheduling deliveries by section
Check thickness, edge type and size on the delivery label. Count full rows separately from pieces cut for steps. Agree pallet locations with the person responsible for roof load capacity.
Measurements for maintenance
File the section number, measured height and a photograph taken before installing the coping. When the covering is renewed, these records help identify where an extra layer requires the termination to be redesigned.
