HEMP DRYWALL

Respira Drywall

RespiraDrywall lines internal walls and ceilings and replaces plasterboard, OSB and particleboard with one hemp board. Paint it, render it in clay or lime, or leave it exposed. It shines in feature ceilings, batten and board, and suspended ceiling grids.

What it is

RespiraDrywall is natural hemp drywall, a like-for-like replacement for plasterboard. Cleaned hemp hurds, a formaldehyde-free binder, no gypsum, no cement. Vapour-open, so healthy indoor air is built into the wall.

18mm square edge or 30mm tongue and groove, in 1200 × 800mm or 2400 × 600mm sheets. Fixed to timber stud frames or adhered to existing masonry like concrete tilt panel or double brick. Takes paint, plaster or render straight on. For external walls, use RespiraBlocks.

RespiraDrywall can be used both as an internal wall lining, plasterboard replacement or an exposed ceiling panel. It’s light and fast to install.

Also works to create a thermal shield from cold walls like concrete tilt panel and double brick. Stops that cold to the touch feeling. Transforming apartments and commercial spaces.

It always comes with:



  • Support and technical guidance from pre-construction to aftercare

Nothing to off-gas

Hemp hurd and a formaldehyde-free, VOC-free binder — no gypsum, no cement, no synthetic resin. That new-house smell that lingers for months is the wall, the adhesive and the paint releasing what's in them. This one has nothing to release.

Handles moisture, doesn't trap it

A sealed wall traps whatever moisture gets in — and trapped moisture is where mould takes hold. RespiraDrywall is vapour-open: it takes moisture in when the air's damp and gives it back when it dries out, instead of holding onto it.

The room feels calmer

Hemp holds heat — specific heat 2100 J/(kg·K), around double gypsum's — so temperature swings less and the room holds its warmth. People describe rooms like this the same way: calm, quiet, less stuffy.

What people say.

Hempcrete granny flat in Kew, Victoria

“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

“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.”
