GoTherm is a specialist insulation company that manufactures expanded polystyrene (EPS) at our North Dublin facility. Our priority is to provide the best U-value, highest quality products and competetive prices. We offer graphite EPS at both retail and wholesale prices. We also supply materials needed in External Wall Insulation projects such as fasteners, adhesives, base-coat, mesh, primer and renders. All products are manufactured in accordance with current E.U. standards under the CE mark, and tested in E.U. notified laboritories. Our polystyrene products are silver-grey boards in various dimensions and thicknesses. Graphite is added to the raw material which absorbs and reflects heat radiation and significantly improves insulation properties by as much as 20%.
