Скачать или смотреть Why Old 70s Homes Feel So Cold (And How to Fix It)

Join me as I revisit my 1970s AV Jennings home in Melbourne, 5 years after major upgrades. From ~30 ACH leaks to ~2.5 ACH super-airtight performance – this is the nitty-gritty of what actually works for older Australian homes. We removed gas appliances, ditched leaky ducted heating & evaporative cooling, spray-foamed the subfloor, added wall/ceiling insulation, retrofitted triple-glazed windows, installed heat recovery ventilation, and sealed everything. Result? Dramatically better comfort, quieter home, no more drafts, healthier indoor air, easier heating/cooling with just one small split system, and huge energy savings potential.
Perfect for owners of 1970s brick veneer homes facing high bills, cold winters, or summer heat in Melbourne/Victoria.
