Roofs – Concrete – PMR


Key Features

In a protected membrane roof (PMR), also known as an inverted roof membrane assembly (IRMA), the insulation is installed on top of the membrane.

The insulation may be exposed to water, so it should have minimal water absorption characteristics. Extruded polystyrene (XPS) is the most suitable type. The XPS boards are placed over the membrane and held down by a layer of ballast or loose pavers on top.
