# Recess-Mounted Venetian Blind

Recess-mounted Venetian blind — the rail seats into the window recess. Depth condition, tolerance and the cleanest look.

## The Rail Sinking Into the Recess

In a recess set-up the headrail sits on the window void's inner wall and the blind runs inside the recess. Seen from outside only the slats are visible; the rail stays on the same plane as the wall line.

This position is the Venetian's cleanest-looking form but its price is the recess itself. Sufficient depth must exist for the rail, the slat pack and the tilt mechanism.

## Depth and Placement Conditions

Flush set-up passes four checks. If one does not fit, the plane changes.

Recess depth, tolerance and obstacle checks in a recess set-up
Check — Required — If It Does Not Fit
Recess depth — A share swallowing rail and slat pack — The rail stays out front; move to wall
Side tolerance — A symmetric narrowing share — The rail jams or slides to one side
Sash opening — No clash with the inward-opening sash — The sash touches the blind; wall is chosen
Casing protrusion — A gap behind the rail — The rail is brought forward; the look changes

## What the Flush Position Brings

- **Lowest edge leakage** — Since the blind runs inside the recess light leaks only from the tolerance share. It cannot be compared with a rail standing on the wall.
- **Free window sill** — If the sill top is occupied the flush blind does not clash with it. Pots and décor stay in place.
- **Integrated look** — When the rail sinks to the wall line the window looks as if it carries its own accessory.
- **Radiator freedom** — A blind staying inside the recess moves away from the radiator in front of the window and does not block the heat flow.

## The Recess Set-Up

The measurement is not a single value; the recess is read from three points.

1. **The recess is measured at three points** — Top, middle and bottom widths are read separately; the narrowest value gives the rail length.
2. **The tolerance share is deducted** — The share dropped from the finished size lets the rail sit comfortably rather than scrape the recess.
3. **The points are screwed to the inner wall** — The connections are marked on the rail line; the recess side walls are sought to be solid.
4. **The rail is locked and tested** — The slats are lowered fully and closed; the clash with the sash opening is probed one last time.

## A Recess Whose Depth Falls Short

If the depth can barely swallow half the rail the choice splits in two: either it is passed to wall mounting or a thinner-profiled rail series is turned to.

A half-flush look is not acceptable. A rail staying out front is both an aesthetic and a function loss; the slat pack hangs outside the recess and can clash with the sill.

## Questions About Recess-Mounted Venetian Blind

How is the measurement taken in a recess?

The recess width is read from three heights and the narrowest value is taken; production drops the tolerance from this value. The depth is reported together with the rail series.

Is recess possible on an inward-opening window?

Not if the sash touches the blind. The sash movement line is checked before the rail; in a clash the wall or ceiling is chosen.

How deep must the recess be?

A share fully swallowing the rail profile and the slat pack is needed. The exact figure changes by the rail series and is given with the product.

## Send the Recess Measurement

Once the depth and the three-point width are shared the recess suitability is finalised.
