Solicitações De Construção E Edificação / Painéis Estruturais / Bulgária

We are looking for gypsum fiberboard. For our current project we need an alternative for this product - We need two layers 10 mm thick each, which are attached to each other. Dimensions of the panels 1500 x 1000 mm, approximate 1500 sq.m. total. Please tell me if you could provide such product. Thank you very much
