How tall? How thick? Nudura Walls to the Roof

In the past, many architects and builders believed that ICFs were only suitable for foundations – rather than the entire building envelope.


If the structure is engineered, you can use Nudura to build as high as you please. Of course, as the building gets taller, the thickness of the wall will increase. The reinforcing steel within the wall may get thicker or become spaced closer together. Otherwise, you might use Nudura ICFs as an infill or curtain wall with a post and beam structure.

Our prescriptive data will take a residential project up to two stories before requiring engineering. However, there are many projects on a commercial level that have gone up multiple stories using Nudura ICF to form structural walls.


Nudura Insulated Concrete Forms come in five standard cores, from 4 inches (100mm), 6″ (150mm), 8 (200mm), 10″ (250mm), to 12″ (300mm). Nudura also sells the form units in unassembled forms to enhance flexibility.

Nudura’s 4 Way Web Connector allows you to take any of these thicknesses and combine them to achieve different combinations of larger sizes.
