Walls and Roofs
Welcome to the Walls and Roofs discussion forum! This is the place to connect with other homeowners, builders, and designers to talk about one of the most vital parts of any new build or renovation: the building envelope. From framing and insulation to roofing and windows, the decisions made here determine a home's energy efficiency, comfort, and durability.
Whether you're planning a project in the varied climates of the USA and Canada or navigating the specific challenges of the UK, Australia, or New Zealand, your questions and experiences are welcome. Let's share our knowledge on creating high-performance, resilient, and sustainable walls and roofs.
Comparing Wall Systems: SIPs, ICFs, Double-Stud, or Standard Framing?
Are you deciding on the best wall assembly for your new home or addition and trying to weigh the pros and cons of different systems? What has been your experience with the cost, construction speed, and performance of Insulated Concrete Forms (ICFs), Structural Insulated Panels (SIPs), double-stud walls, or advanced 2x6 framing with exterior insulation? Share your opinions and ask for advice from those who have built with these methods. We also have Canada's and the USA's most comprehensive high performance and sustainable prefabricated and modular homes directory available here, searchable by Province or State, as well as the largest online directory of green construction contractors and the best and most experienced Architects that are skilled in designing sustainable homes to LEED and Passive House standards here on EcoHome.
Questions on Insulation, Air Barriers, and Vapor Control
Do you have specific questions about choosing the right insulation material, or where to properly locate your air and vapor barriers for your climate? This is the forum to discuss the technical details, such as the benefits of mineral wool versus spray foam, the importance of taping air barrier seams, or whether you need a smart vapor retarder. Getting these layers right is essential for a healthy, high-performance wall and roof assembly.
Share Your Sustainable Roofing and High-Performance Window Experiences
What type of roofing material did you choose for your sustainable home, and how has it performed? Have you installed a metal roof, a green roof, or chosen high-performance triple-pane windows? Share your stories, photos, and any tips you have on installation, durability, and cost. Your real-world feedback can help others make informed decisions for their own building envelope projects.
