Contrary to popular belief the cores of our product are not made of a petroleum based plastic, and the only cement it uses is the minimal content of the cement board sheathing (skins) of our panels (less than 0.65% of the whole panel). The core polymer is made from a hydrocarbon base and we believe such insulating materials are the most environmentally responsible usage of hydrocarbon based products simply because they don’t have to be destroyed to do their work, unlike fuels – the longer you use them, the more energy they save.
 

 
The cores of our product constitute 90% of each panel, and 98% of this is air. This makes the Mantle Panel a uniquely esource-efficient building material with a very small carbon footprint. Thousand and more of tones of EPS are recycled every year in the UK, alone. As a single polymer EPS is straightforward to recycle and is recycled into items such as replacement hardwood decking or garden furniture, coat hangers and disposable cameras. Our core is HFC, CFC and HCFC free and Pentane is used as its blowing agent.
 

 
Pentane has a Global Warming Potential* (GWP) of zero. (The EU does not register pentane as a substance hazardous to human health or the environment.)
In combustion the amount of carbon monoxide and particulates given off by EPS is a small fraction of that emitted by wood or cardboard. EPS is inert and innocuous and provides stability in landfill because is does not biodegrade and leach chemicals into the water system or gases into air that could contribute to global warming.
Further, the manufacture of EPS is a low pollution process. Steam is the key ingredient and the water is re-used many times. There is no waste in the process as all cut off or rejects are re-used.
