How are internal services accommodated?
A. Electrical conduits and water pipes can be recessed into chases melted into the polystyrene at the time of installation. SPECIAL NOTE: PVC cables should be kept from direct contact with polystyrene by placing it inside plastic conduit. This is to stop the cable sheathing reacting with the EPS and becoming brittle over time. However, low-smoke cable and plastic plumbing can remain in direct contact with EPS without issue.
