Concrete floor and stair inside the Oatlands duplex during construction

Our approach

Concrete subfloors, not particleboard.

Subfloor framing

Why we do not use yellow tongue.

The usual suspended timber floor is particleboard, commonly called yellow tongue. It is economical, but it is not moisture resistant and can only sit exposed to weather for a short time before it risks swelling, softening or delaminating.

Where a project is not built on a concrete slab, Avern lays AlphaFloor solid precast concrete panels instead, as standard on every suspended subfloor.

Why it matters

What AlphaFloor brings to a home.

Unaffected by rain

A 25 MPa precast concrete panel, so rain or humidity during construction cannot swell or soften it.

Non combustible

A solid concrete floor rather than a sheet of compressed wood particles.

Quiet underfoot

Exceptional acoustic performance that cuts sound and floor vibration, comfortably beyond the code for Class 2 and 3 buildings.

Thermal mass

Concrete helps hold indoor temperatures steady, like a solid slab.

Made in Australia

A 35 mm solid concrete panel manufactured to ISO 9001 quality standards.

More of the Avern standard

The rest of the envelope.

A sealed, breathable envelope

Every external wall and roof plane is wrapped in a Proclima membrane, every join, lap, penetration and window reveal taped into one continuous air and weather barrier.

Straight LVL wall framing

LVL replaces standard MGP pine in every wall frame. It stays straight and plumb, so the membrane and insulation stay continuous.

Double glazed, thermally broken windows

Our minimum on every project. We push for uPVC or timber frames, which do not run hot and cold the way aluminium does.

Questions

Concrete subfloors, answered.

A 35 mm solid precast concrete panel, rated 25 MPa and made in Australia to ISO 9001 standards, laid over a suspended floor frame instead of particleboard.

No. AlphaFloor is for suspended floors. A home on a concrete slab already has a solid floor.

Yes. It gives a suspended floor the acoustic performance of a solid slab, cutting sound transmission and floor vibration between levels.
