DUO is a three-in-one lightweight fiber reinforced polymer formwork system that can be used to form walls ... Allows a permissible concrete pressure of 1,050 sf for walls and 1,650 sf for columns ...

Designed for applications where two walls intersect Short leg and long leg ... deep FormLock reversible interlock connects the forms tightly together without the need for gluing or taping ...

The core of an insulated concrete form wall consists of reinforced concrete encased in rigid insulation, creating a strong, load-bearing structure that resists environmental and structural stresses.
