H2wall is a constructive system designed for the containment of concrete walls, combining the disposable formwork's function with the elevated insulating features of polystirene. It's made of two EPS slabs connected togheter by high density polypropylene spacers. The internal septum thus formed is available in four heights: 10/15/20/25 cm. EPS slabs are available in 6,3 - 9,3 - 12,3 - 16,3 cm thicknesses.
