Steve walks through the installation of high-performance, triple-glazed European windows, including unique archtop designs. He details the use of aluminum frames, thermal breaks, and custom OSB and zip liners for airtight and thermally efficient setups. Special emphasis is placed on rough opening preparation, flashing techniques, drainage, and why drying and venting matter more than sealants. Illustrated construction drawings are shown and explained with practical insight. Steve also promotes his broader philosophy on building science, encouraging viewers to prioritize performance over aesthetics. Bonus: he gives a shoutout to fellow contributors from different trades on the Build Show platform.
