PMR First ... to Last
What’s up on the rooftop? If it’s a protected membrane roof (PMR), just about anything can be up there – from a garden or green roof to rooftop plazas, decks, terraces, walkways and more.
The PMR assembly (also known as an inverted roof membrane assembly, or IRMA) with STYROFOAM™ Brand Extruded Polystyrene Insulation above the waterproofing membrane, has represented the best in flat roof technology since it was developed and patented by Dow in 1968. Back then, few could have foreseen the dramatic results that PMR assemblies would deliver to building owners: Some of these original roof membranes remain in exceptional condition – more than 40 years after they were installed.
Trying to decide between PMR and a conventional roof? You may find the decision is easier than you thought – especially after learning more about the advantages and sustainability benefits of PMR.
