Dow Roofmate SL Avance (shiplap) extruded polystyrene insulation from Dynamic Composite Technologies  is designed to be installed above water-proofing membranes in protected membrane roof (PMR) applications.

Dow Roofmate SL Avance extruded polystyrene insulation works with the roof membrane to maintain a steady temperature, and reduce the harmful effects of thermal cycling, expansion and contraction, ultra-violet degradation and mechanical damage – the most common causes of premature roof failure.  

Dow Roofmate SL Avance extruded polystyrene insulation is ideal for load bearing applications such as roof gardens because it offers high compressive strength and a long-term retained R-value. Dow Roofmate SL Avance is a lightweight, mould and decay resistant solution that is available in custom shapes and sizes to suit individual projects.  

Blowing agents with zero ozone depletion potential (ODP) are used in the manufacture of Dow Roofmate SL Avance extruded polystyrene insulation. In addition Dow Roofmate SL Avance is Green Star compliant, CO2 blown and has a fire rating of AS1530.
