Bosnie-Herzégovine Demandes

Hello, I am looking for companies that export xps - insulation. Can you give me some recommendations? We are planning to build more residential buildings in Sarajevo, the new building we are start on requires an amount of 2200,0 m2 XPS. So please can you send me an offer of XPS, which will be used for the walls inside the construction pit, and on which waterproofing is installed. The XPS thickness required is 5cm and 10cm, 300kPa.
