Expanded Polystyrene (EPS) is a lightweight cellular plastic material consisting of small hollow spherical balls. It is this closed cellular construction that gives EPS its remarkable characteristics. EPS is produced in a wide range of densities providing a varying range of physical properties. These are matched to the various applications where the material is used to optimise its performance and strength. The manufacture of EPS uses less than 0.1% of global crude oil as a feedstock however it can deliver up to 200 times its own resource in thermal energy savings.
Rigid polyurethane (PUR) or polyisocyanurate (PIR) foam blocks manufactured through a controlled foaming process, free of CFC and HCFC. The manufactured products are excellent thermal insulators with high mechanical properties, high rigidity and light weight.
Rockwool or mineral wool, is a type of insulation made from rock (such as volcanic rock) or from the slag castoffs from iron ore processing. It is melted and then spun at high speeds through a thin mesh to create strands, similar to the process used to make fairy floss.
