I want to buy ceiling plaster board

could you send us a price list per m2 for Plasterboard Knauf 12.5mm 125/200 CW and UW profiles

Am looking for a waterproof plasterboard (green). The dimensions should be 120 cm or 125 cm wide and 18 mm thick. For the length I need a measure of at least 260 cm. The best would be 280 cm. But can also have standard dimensions (eg 300 cm).
