# Vertical Zip Screen

The standard form for façade, pergola and terrace edges. The fabric is zip-locked on two side rails and travels top-down.

## The System’s Four Parts

In the vertical form the fabric descends from above and locks on two side rails.

- Top Cassette The enclosed aluminium unit carrying the motorised roller tube. The fabric stays protected inside while gathered.
- Zip Guide Side rails housing the fabric’s two edges. The fabric travels locked in the channel — wind cannot pull it out.
- Technical Fabric PVC-coated screen over glass fibre. The chosen openness factor sets light, view and privacy.
- Bottom Bar The weighted profile keeping the fabric taut. On closing it seats flush to the sill or floor.

## Control Types

The same system runs on three power options. Supply and frequency of use make the choice.

Vertical zip screen control types and suited uses
Control — Operation — Suited Use
Motorised — Travels up and down by remote or smart system — Standard application; sensors can be added
Solar Motorised — Panel battery — no supply line needed — On façades and pergolas where power cannot be drawn
Manual Crank — Vertical travel by crank handle — Small sections with no power infrastructure

## Standout Features

What the zip lock means outdoors.

- Wind Resistance The zip edge is locked in the rail — the billowing a free roller suffers never happens in this system.
- Insect-Screen Duty Fabric edges descend sealed; the lowered blind raises a barrier against insect entry.
- Heat Before the Glass The solar load is met on the outer surface; heat entering the interior falls noticeably.
- View Preserved Openness-rated screen shows the outside from within while cutting the view from outside.

## Questions About the Vertical Zip Screen

How does the vertical zip differ from a roller blind?

The fabric edges interlock to the side rails with the zip profile. In wind the fabric cannot leave the rail or flap like a wing; a free-hanging roller cannot give that resistance.

Does it work manually?

A crank model exists, but the system is motorised by nature; on wide sections and with sensors a motor is required.

Can the fabric be changed?

Screen openness is chosen between 1–10%. Clear PVC for full view and blackout fabric for darkening are both possible in the same system.

The balcony and façade types where the vertical zip arrangement mounts are listed in the [application areas](https://www.fenetresystems.com/en/zip-screen-application-areas/); its horizontal-closing sibling is described on the [horizontal system](https://www.fenetresystems.com/en/horizontal-zip-screen/).

## Let Us Choose the Section and Motor

Once the opening measurement and wind direction are relayed, a system size and motor type are recommended.
