# Threshold-Free Pleated Insect Screen

The form where the bottom rail drops to the millimetre range — no step at the passage; barrier-free use from wheelchair to pram.

## What Is the Threshold-Free Form?

The threshold-free pleated insect screen is the passage form that drops the bottom rail height to 7 mm and below — there is almost no protrusion on the floor; the door threshold is crossed without tripping.

On a standard pleated, the bottom line guiding the mesh rises a few centimetres — in this form the guiding is solved with a low-profile rail; the mesh works on the same tension arrangement.

## Small Protrusion, Big Difference

A threshold looks small on paper but grows in daily life — a wheelchair bumps over it, a pram catches on it, bare feet step on it, the broom hits it. The barrier-free form solves these four scenes together.

Accessibility is not only a special need — on every door with a high passage frequency, a low rail is directly usage quality.

## Who Does It Make a Difference For?

Three passage scenarios — the real cost of the threshold is measured here.

Passage scenarios and gains of the threshold-free pleated insect screen
Scenario — Lived with a Threshold — Gained Threshold-Free
Wheelchair — The wheel does not catch on rail height — A fully barrier-free passage
Pram — Passage without lifting or jumping over — Everyday ease of use
Dense Passage — Bare feet and slippers do not trip — Balcony and terrace doors

## Standout Features

The aspects of the barrier-free form that make a difference in daily use.

- ≤7 mm Rail The bottom rail height drops to a few millimetres — no step on the floor.
- Barrier-Free Passage Wheelchairs, prams and scooters cross comfortably.
- Trip-Free Guide The low-profile line still guides the mesh.
- Door Focus The comfort-focused form of balcony and terrace doors.
- Durable Line A low profile resistant to foot and broom contact.
- Accessibility The top-level solution of the pleated segment for barrier-free use.

## Questions About the Threshold-Free Pleated Insect Screen

Does threshold-free mean completely rail-free?

No — the rail height drops to 7 mm and below; a low-profile line guiding the mesh remains but forms no step.

Does the mesh stay in place on the low rail?

The guide line keeps directing the mesh. It demands care under hard wind and cleaning knocks — on windy façades the channelled series is evaluated.

Can it be applied to every door?

It is ideal on flat-floored passages. Where marble or a raised threshold sits on the floor, an arrangement resting on a ramped profile is recommended.

What is the difference from the standard pleated?

The bottom rail profile — on the standard the rail rises a few centimetres, on threshold-free it drops to the millimetre range. Mechanism and mesh are the same.

Rail heights and ramped alternatives are given on the [installation types page](https://www.fenetresystems.com/en/pleated-insect-screen-installation-types/); the arrangement travelling on the rail is described in the [sliding form](https://www.fenetresystems.com/en/sliding-pleated-insect-screen/). The passage areas where the ≤7 mm rail is required are marked in the [application areas](https://www.fenetresystems.com/en/pleated-insect-screen-application-areas/).

## Send Passage and Floor Details

Once the opening measurements and floor state are relayed, a threshold-free or ramped arrangement is recommended.
