Icopal has extended its range of Anderson Monarflex pitched roof breather membranes with the launch of Monarperm 500.

The 500 series is a lean version of the renowned 700 marque, with corresponding high-performance. It eliminates the need for traditional eaves/ridge ventilation in warm or cold pitched roofs while helping to meet the Part L Building Regulations by improving airtightness and reducing energy consumption.
Monarperm 500 comprises a special three-layer composite structure with a unique microporous film that provides an effective role in condensation control without the need to vent.
