Healthy indoor air

The wall decides what you breathe.

Nothing to off-gas

Hemp hurd and a formaldehyde-free, VOC-free binder. That new-house smell is chemistry leaving the walls for months — there is none in this to leave. Von Hanf sell it into schools and offices for exactly that reason.

Nowhere for mould to start

Mould is not dirt. It is water that cannot leave. At µ 5 this board is close to open air — damp moves through it and back out instead of condensing inside the wall where you will never see it.

Air that regulates itself

The board takes humidity up when the room is damp and gives it back when the air dries. No filter, no fan, no maintenance — the wall simply does it, every day it stands there.

A normal wall is built to stop moisture. This one is built to move it.

Every house makes moisture — showers, cooking, drying clothes, breathing. A conventional wall is built to stop it getting in: gypsum, paint, a vapour barrier. When moisture gets past that anyway, and it always does, it has nowhere to go. That is where mould comes from. Not dirt. Trapped moisture.

RespiraDrywall does the opposite. It takes moisture in when the air is damp, moves it through, and gives it back when the air dries out.

Same trades, same tools, same afternoon. A different wall at the end of it — and a different room to live in.

Semi-rigid. No sag or slump

Beautiful Natural finish and feel

AS/NZS 1530.3 fire-rated for Australian builds

Standard plasterboard

Standard Insulation

Paper-faced gypsum, adhesives and paint off-gassing for months

Often vapour-beading, moisture sits next to and absorbs into timber frame

Moisture stops at the sheet and stays in the wall

Glass and mineral fibres irritate skin, eyes, and lungs

Damp that cannot leave is where mould begins

Resource-intensive synthetic or mineral manufacturing.

Average, cheap look and feel

Often contains formaldehyde or chemical fire retardants

Hollow and drummy — the wall sounds like what it is

Variable — often requires separate acoustic product

Low thermal mass — the room heats and cools fast

Performance can degrade or sag over time

Trapped humidity degrades insulation batts.

Skim, stop and sand the whole wall before you finish

Fire-rated but often relies on chemical retardants

What people say.

Kew Hempcrete Secondary Dwelling exterior

Bea Dubinsky · Granny Flat, Kew

Will provided complimentary consultation to our builder before and throughout the build, making the building process seamless. We now enjoy the wonderful thermal and sound insulation properties of hemp, as well as a healthy indoor air environment. Will and Ima are both so passionate and knowledgeable about hempcrete construction and offer outstanding customer service — they were helpful, responsive and always available to help. I would recommend Respirabuilt for anyone considering a sustainable and affordable building solution.

Bea Dubinsky · Granny Flat, Kew

Chris Hopkins · Bega

Have used Respirabuilt hempcrete blocks in a block-and-cast construction. Will and his team have been great to work with from the planning stage through to the build stage. As an owner-builder, they have been invaluable in making the dream of building a sustainable and energy-efficient house possible.
