Product Specifications External Wall Insulation Board Thermal Conductivity BRE Green Guide A Rated Manufactured without Xtratherm Warm-R is a high quality expanded Polystyrene containing integrated graphite within the cell structure that reflects and absorbs radiant heat resulting in an improved thermal insulation performance. The Xtratherm EWB/EPSP is an Expanded Polystyrene with Graphite/Carbon Enhancement. The graphite particles act as infrared absorbers to reduce heat dissipation caused by the radiation. This improves the thermal conductivity on conventional expanded polystyrene products. Xtratherm EWB/EPSP provides thermal insulation to new and existing rendered (All surfaces should be sound) Xtratherm EWB/EPSP insulation board is suitable for mechanical fix to sound substrate using approved fixings at a specified rate per board. When considering use on uneven surfaces then bedding shall be required in accordance with Xtratherm EWB/EPSP range Quality Management System Environmental Management System Occupational Health and Safety Management Systems.
