Dow Roofmate TG Avance™ (tongue and grooved) extruded polystyrene insulation is designed for installation above waterproofing membranes in protected membrane roof (PMR) applications.
Dow Roofmate TG Avance™ insulation helps the roof membrane maintain a steady temperature, minimising 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 TG Avance™ extruded polystyrene insulation offers a long term retained R-value, high compressive strength and superior moisture resistance for protected membrane roofing applications, making it the perfect solution wherever superior load bearing and insulating capabilities are specified.
Dow Roofmate TG Avance™ insulation does not support mould growth, will not crumble, or decay, making it ideal for insulating roof gardens. Dow Roofmate TG Avance™ insulation is strong, yet light- weight and easy to fabricate into various sizes and shapes to meet your specific design requirements.
Dow Roofmate TG Avance™ extruded polystyrene insulation is not manufactured with CFC/HCFC/HFC blowing agents. It meets EU Environmental standards, has zero ozone depletion potential and is GreenStar compliant.
Australia is set to ban HCFC imports by 2015.
