Green, insulating and affordable

The insulating formwork PLASTBAU ®-3 is a pre-built, rigid, easy to install and fix building element. The two high-density expanded polystyrene sheets, which fulfils the function of containing the concrete casting, stay in place as a thermal insulating super performing layer. The final result is an insulating, reinforced concrete monolithic structure.


Height: from 900 to 4500 mm
Thickness of EPS: from 50 to 250 mm
Width: 1200 mm


Weight: 11.5 kg/m2 (dep. on thickness)
U-value: from 0.29 to 0.1 W/m2K
Temperature range: -40°C to +50°C

A standard formwork of 120 cm wide and 300 cm height, weighs only 39 kg. It can be easily manipulated and installed with no need of lifting equipment, just by hand.

One of the great advantages, in addition to energy saving and anti-seismic resistance, is the laying speed which, from the first manipulation till concrete casting, can vary between 15 and 20 min per m2 of wall.

Depending on the project, EPS panels can have different thicknesses, to ensure a greater level of thermal insulation. The internal panel is generally 5 cm thick, whereas the outer one can change from 5 to 25 cm. The PLASTBAU ®-3 system is a complete construction system, designed to facilitate installation and the entire construction phase, reducing construction times by 40% and costs by 30% compared to traditional systems.

It appears to be extremely efficient for the construction of zero energy buildings as indicated by PASSIVE HOUSE or MINERGIE HOUSE, as prescribed by Directive 2010/31 / EC which provides that by 31 December 2020 all new buildings must be nZEBnearly Zero Energy Building”.


The PLASTBAU ®-3 System, taking advantage of the EPS insulating coefficient, allows to build zero energy buildings which can perfectly adapt to all climate.


It’s an affordable construction method. Saving on construction time, tools and products costs, you can decrease construction costs up to 40%.


Thanks to its iron armour and to the high quality of the EPS, the PLASTBAU ®-3 is anti-seismic level 1 and resistant to extreme climate elements.


Thanks to the fast and simple laying of formwork panels and concrete casting, the PLASTBAU ®-3 Wall system allows you to reduce constructions time up to 40%.


Both with extreme heat or cold, the PLASTBAU ®-3 Wall garantees maximum insulation, allowing a total savings on energy costs.
