How this node works
Over the opening a «U»-shaped AAC block is used as permanent formwork: it is reinforced and filled with concrete to form the lintel, keeping the same material on the face so the insulation stays continuous and no thermal bridge is created.
Key points
- AAC block (top course)
- U-block lintel (permanent formwork)
- Concrete + reinforcement
- Opening reveal
- Window frame
- Insulation continuity (same material)
