G-2049, PENTRU PROIECTII ASUPRA ELEMENTELOR STRUCTURALE
INTERMEDIARE
Pentru aceste aplicatii,sistemele de spuma,trebuie sa garanteze
stabilitatea dimensionala,recomandand sisteme cu densitate
superioara sau egala cu 35kg/mc.
Tecnopol Sistemas a dezvoltat sistemul G-2049 cu o densitate libera
de 35kg/mc si o rezistenta la compresiune de 200kp.
