Roger Joyner is a leading advocate for high‑performance building envelopes in Western Australia, bringing decades of architectural and building‑science experience from the UK and Australia. After early recognition for award‑winning solar‑passive homes, Roger transitioned into Passivhaus design, driven by a commitment to reducing energy waste and improving indoor environmental quality. This path led to the founding of Passivhaus Perth and, ultimately, to his core focus today: supplying world‑class Pro Clima systems through WA Membranes.
As Western Australia’s dedicated Pro Clima distributor, Roger provides builders, architects, and consultants with industry‑leading membranes, tapes, and airtightness solutions that elevate building durability, comfort, and moisture safety. His expertise in thermal‑envelope design, airtightness detailing, and blower‑door testing ensures clients receive both the right products and the technical guidance to use them well. Through WA Membranes, Roger champions healthier, more resilient, ultra‑low‑energy buildings across the state.
