Super Low Uw Passive House Window, Outward Opening

Bloomcabin 1 sash with 2 horizontal glazing bars and 1 vertical glazing bar. Bloomcabin combines all three bars within a single passive-house sash. The result is a layered window pattern with a clear tempo and an organised, architectural presence.

Why explore this Bloomcabin layout?

1. Structured on three axes

   A pair of crossbars divides the sash at two levels, while one upright passes through the composition. Each pane is clearly defined, and both directions remain in visual balance.

2. Ordered glazed sections

   Successive lines across the glass establish rhythm; the vertical element then adds definition through the height. Their interaction gives the window a strong character and a carefully resolved grid.

3. Efficient by design

   The window is oriented towards energy efficiency and a welcoming residential interior.

Where a building scheme calls for a more detailed single-sash treatment, this option offers three horizontal areas together with one vertical division. The grid supports a façade that feels classically composed without appearing busy. It uses 1 sash with 2 horizontal glazing bars and 1 vertical glazing bar, arranged in balanced proportions for coordination with the architecture. Review the individual project and your preferred design outcome before choosing the final configuration.
