VoidLam

What Is VoidLam?

VoidLam combines voided concrete with cross-laminated timber (CLT). By combining the compressive strength of concrete with the tensile strength and light weight of timber, VoidLam opens more options for mass timber applications. The carrying capabilities of the voided concrete above means the removal of wooden beams below. This provides a clean span and allows for MEP installation within the concrete.

Who's VoidLam For?

CLT looks amazing. It is no surprise that an increasing amount of modern buildings are made with timber. VoidLam provides larger spans with less overall height as well as greater flexibility in design.

For the architects and designers, VoidLam offers the best of both worlds. Lighter concrete slabs increase interior spans enabling wider halls, dining spaces, offices and more.

With CLT pre-bolted with the slab, VoidLam offers easy installation of beautiful timer ceilings with polished concrete floors. 

VoidLam is for developers who want the strength of concrete as well as the gorgeous appearance of timber.

First, our voids and reinforcement are placed onto a sheet of CLT. Rebar chairs are not required as they are already built into our system. Finally, a single pour of concrete completes VoidLam.

Although the tenant may never understand the science behind VoidLam, they will surely feel the benefits. Because of the CLT, VoidLam has a much higher r value then both traditional concrete slabs and the simpler VoidDeck.

The tenant will feel better thermal insulation properties, better sound dampening properties as well as the enhanced beauty of timber construction.
