DUO Lightweight Handset Formwork

The universal lightweight formwork for walls, columns and slabs
Taller walls are formed just as easily
Ideal for foundations
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.
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

Engineered polymer replaces steel, aluminum and plywood

Lumber, steel, aluminum and plywood have been the standard for decades in the US when it comes to formwork due to the lack of cost effective and sturdy alternatives. PERI is challenging this notion with its brand new Fiber Reinforced Polymer (FRP) formwork system “DUO”. The engineered plastic achieves its strength through fiber reinforcements, thus allowing a permissible concrete pressure of 1050 PSF for walls and 1650 PSF for columns while maintaining the lightweight attributes of polymer.

Lightweight, Handset System

With only 4 lbs per sq. ft. and conveniently shaped standard panel sizes of about 3 ft. x 4½ ft., DUO is a true handset system, specifically designed to be handled without the need for a crane. If crane time happens to be available, entire sections can conveniently be lifted as gang forms using a simple crane hook connector.

Labor friendly

Very few parts and pieces and an intuitive assembly sequence makes DUO ideal for markets with a shortage of skilled labor. Instead of hammered-in wedges and clamps, DUO panels are connected using a red coupler that resembles a door handle in both appearance and in the simplistic motion in which it is installed.

Flexible Application

One of the truly unique features of DUO is the ability to use the same panels for walls, columns and slabs – with only a few extra parts required for the conversion, this not only saves on initial investment costs but also on storage space and trucking costs down the road.

Silent System

For the most part, DUO is assembled with no tools, resulting in significant noise reduction on the job site, which in turn makes DUO a preferable solution in areas where construction noise is a concern (i.e. residential).
