Recently, Siegware, in partnership with the Australian Passive House Association (APHA), held another training day as the practical component of the Passive House Tradesperson course. Wade Bashaw from North South Homes and Andrew Ferguson from Siegware, along with 9 students, wrapped and sealed a small training pod inside and out using Isocell membranes and tapes. Additionally, students successfully installed two windows to an airtight standard. Joel Seagren from Fantech also delivered a great session on HRV (Heat Recovery Ventilation).
