Heavy Hydro Type

The Promonta HEAVY Hydro type is a solid gypsum block with higher density (1250kg/m³) than the Normal Hydro type block and therefore with better results in terms of acoustics and much higher mechanical strength.

 

According to the new standards of the ATG, the Technical Approval, it is now required to ask a waterproof first raw of blocks, recognizable by its blue color, everywhere so as to avoid any risk of ascent of dampness. Waterproof block is also required in so-called water rooms such as bathrooms or shower rooms; as long as there is a higher level of dampness than normal in these rooms. Hydro block is processed in its mass, so it gets less than 5% of humidity absorption after 2 hours of immersion.
