Super Low Uw Passive House Window, Outward Opening

Bloomcabin 1 sash with 4 horizontal and 1 vertical decorative bar. This passive house window uses a particularly detailed arrangement. A regular grid orders the glazed surface and gives the whole window an immediately recognizable identity.

What distinguishes this Bloomcabin layout?

1. A closely spaced grid

   Within 1 sash, 4 horizontal bars establish an even succession of glazed areas. The 1 vertical bar ties the layout together, combining precise order with a confident visual presence.

2. Consistent divisions from every angle

   Several side-to-side lines create a pronounced rhythm across the window. The upright bar further organizes those areas, so the pattern remains easy to read from different viewpoints.

3. Efficiency with indoor comfort

   This passive house window is focused on high energy efficiency and is intended to help the interior feel comfortable.

Use this version where a passive-house-oriented project calls for a strongly articulated window. The combination of 4 crossbars and 1 upright bar draws a distinctive grid across the façade. In the 1-sash arrangement, balanced spacing helps the window relate to the building’s proportions and intended exterior expression. Its orderly design language can sit comfortably within modern or classic architecture, including carefully renovated buildings.
