DUO Lightweight Formwork

The universal lightweight formwork for walls, columns and slabs
By using only a minimum number of different system components for walls, foundations, columns and slabs efficient forming can be realized.
When forming the slab, work is completely carried out from a safe position below; the panels are simply hooked in and then pivoted upwards.
Due to the manageable dimensions of the DUO panels, these are also ideally suited for the construction of foundations.
The replacement formlining can be mounted by hand using only a few screws – also on the construction site and without any special tools.
DUO is made of technical polymers, that material provides permanent protection against moisture as well as being very light and highly flexible in terms of product design.
An example of easy and simple use: the shape of the DUO Connector and the panel openings allow only one single installation option.

Overview

DUO can be used for foundations, walls and columns as well as for slabs and beams. The system is characterized by the extremely simple handling and the minimum number of different system components. Almost all operations with DUO can be carried out without tools while the working steps are very easy to understand. Even those less experienced users of system formwork can work quickly and efficiently with DUO. New is not only the concept but also, in particular, the material used. Both the panels- including the formwork - and the DUO accessories are made of technical polymers. Due to the low weight, no crane is required for assembly operations.

Universally applicable

Flexible forming of walls, columns and slabs using only one system

Ergonomic in all respects

Low weight, crane-free handling and intuitive application

Easy replacement of formlining

Quick repair with just a few screws - without requiring any special skills

For the team it was the first time they used system formwork. Compared to the use of conventional formwork we were able to save around 50 % of working time. Especially the straightforward application is to be emphasised. The whole team quickly understood the system and worked with little training.
