Passive House windows are not like the typical windows that we are used to in Australia. They require double glazing and sometimes triple glazing, and they open and close in different ways. Glass windows and doors are an integral part of building design, functionality and energy efficiency and they always take a large portion of the budget. So it's critical to know what you're working with before you get started.In today's episode, I talk to Paul Gerrard, the owner of Energy Efficient Windows, about the uPVC windows he manufactures for Passive Houses and high performance homes all around Australia. You'll learn:The different window and door types that can be used in a Passive House, The answers to your questions about UPVC window frames, Plus heaps of other practical info to help you understand how windows work in a Passive House.Australian Architects can claim formal CPD hours for these podcasts.  MORE INFORMATIONFind everything you need on the Renovation Collaborative website. www.renovationcollaborative.com.auPODCAST Key points summary, timestamps and resource linksFREE RESOURCES Transcript edited into clear Q&A.CPD Australian architects can find more information on CPD, and COURSES Eleven easy to read courses demystifying the entire home design and construction process.  KEY POINTS SUMMARY1. Passive House windows are different to the typical windows that we're used to in Australia. The main Passive House options are tilt and turn windows, lift and slide doors and hinged swing doors. These opening types comply with the airtight requirements. They lock the entire perimeter of the window and really compress the seals. 2. Passive House windows need to be double or triple glazed. The option that's correct for your climate zone will be determined through your PHPP calculations. 3. The window frame material is also part of the window energy equation, not just the window glass. It needs to be insulated and airtight and thermal bridge free, meaning that the heat energy can't transfer through the window frame from inside to out, or outside to in. 4. uPVC windows are the most cost effective Passive House window option. Other options include timber thermally broken aluminium and timber aluminium composite. 5. The window brand and type you choose doesn't need to be a certified component through the German Passive House Institute. As long as the required data on the window glass and the frames is available, the PHPP calculations can be balanced with everything else in the house to achieve the Passive House standard. 6. A few facts about uPVC windows: uPVC doesn't off gas like a vinyl floor. It has a very long lifespan. It won't break down in the sun because it contains a special tropical mix for the hot Australian climate. It's 100% recyclable in bushfire areas, It can go up to BAL40 in bushfire zones and...
