One Series

The One Series is Nudura’s single-sided ICF system – insulation on one side, exposed concrete on the other. It’s designed for situations where you need the structural benefits of a concrete wall and the thermal performance of ICF, but with a face that can be left as concrete or finished directly.

Where One Series is used

The One Series is ideal for:

  • Basements and retaining walls where you want a concrete face internally or externally
  • Stair cores, lift shafts and plant rooms that benefit from durable concrete surfaces
  • Internal feature walls where exposed concrete is part of the architectural design
  • Areas where services, fixings or impact make a concrete finish more practical

It can be combined with standard ICF forms elsewhere on the project to create a consistent, co-ordinated structure.


Key benefits

  • Concrete where you need it – one face can be left exposed, painted or directly finished, making it perfect for hard-wearing internal areas.
  • Built-in insulation – the insulated side still delivers the thermal performance and airtightness associated with ICF.
  • Simplified detailing – no need for separate blockwork or additional backing structures in areas requiring a concrete wall.
  • Flexible integration – works seamlessly with other Nudura blocks, so you can switch between One Series and standard forms as the design requires.
