Technical information
Product specification

Structural Voidformer is supplied as blocks, cut sheest or bespoke shaped pieces to suit the application or project.

Standard block sizes are 2400mm x 1200mm up to a depth of 1200mm.

If required depth is greater than 1200mm additional sheets or blocks can be added as required.

Where the application requires Structural Voidformer to accommodate permanent long term imposed loads the
designer should take into account long term compressive creep.
