SBS MB roofing systems can even be Employed in a Secured Membrane Roof (PMR) (at times called an Inverted Roof Membrane Assembly (IRMA)) configuration. If a PMR system is specified, a slip-sheet encouraged via the membrane manufacturer ought to be placed among the membrane along with the XPS to stop the insulation boards from bonding for the membrane. If not, membrane tearing could happen once the insulation moves or floats during a rainstorm.

Block h2o ensuing from ice damming, wind-driven rains and standard h2o move. A properly sealed roof allows prevent rot and mold.

five. Free-Laid Air-strain Equalization System: The membrane is entirely adhered across the roof perimeter, but elsewhere the membrane is only loose-laid. This system should only be used around an air-impermeable roof deck or about an air barrier. To compensate for slight air leakage among the membrane as well as the deck/air barrier, air-pressure equalization valves are mounted at prescribed intervals. The valves are just one-way: they allow air underneath the membrane to vent out, but outside the house air is prevented from flowing from the valve and underneath the membrane.
