@logixbrands: The secret to a flawless roof-to-wall air seal. When building to Passive House standards, your air control layer has to be continuous, especially at tricky transitions like the roof connection. In this video, builder Dennis Borren explains his method for maintaining absolute airtightness using 1.5-inch Halo®️ Interra®️ interior rigid insulation panels. The process is meticulous but highly effective: 👉 Tape every joint of the Halo Interra panels. 👉 Run a poly layer underneath the top plate and seal it directly to the solid concrete ICF core. 👉 Tape that poly directly to the Interra panels to lock the system together. The result? A completely uncompromised, continuous air and vapor barrier from the walls straight through the ceiling assembly. Watch the full breakdown to see how it’s done! 🏗️✨ #passivehouse #customhomebuilder #icfconstruction #buildingscience #constructiontiktok
