Screw-Mounted Pleated Blind
Screw-mounted pleated blind installation — the top rail is screwed to the joinery profile. Screw points, joinery types and removal effect.
How Is a Screw Mounting Done?
It finishes in five stages. Correct marking makes everything else easy.
- 1
The bead line is marked
The top rail is held against the window. The screw points are marked with a pencil. Left-right deviation is corrected here.
- 2
The screw holes are opened
A pilot hole is opened with a thin bit. The screw advances straight without splitting the profile, the profile does not crack.
- 3
The rail is screwed
The top rail is fastened in an alternating screw order. Tightening from one side bends the rail.
- 4
The bottom profile is connected
The tension cords and bottom retainers seat into place. The blind is tested by fully opening and closing.
- 5
The sash test is done
The sash is opened fully. If the rail touches the jamb or the side profile, the position is corrected.
Connection by Joinery Type
The screw changes by the material. The wrong screw wears the profile or cannot hold.
| Joinery | Screw Choice | Point of Attention |
|---|---|---|
| PVC | Short sheet-metal screw | It is aligned to the steel reinforcement channel. The profile wall alone does not carry. |
| Aluminium | Drill-pointed thin screw | The surface is hard. A pilot hole is a must; cold slipping scratches. |
| Timber | Standard wood screw | On old joinery the grain direction is checked. The crack runs along. |
When Is a Screwed Connection the Right Choice?
Own home and long term
If it will not be removed for years, the screw gives the most stable connection. The rail does not loosen, does not sag.
Wide and tall glass
As the width grows the rail load grows. A screwed rail carries it without bending.
Intensive daily use
On a blind opened and closed many times a day, a mechanical connection is stronger than tape.
Motorised-system groundwork
Motor load and vibration are carried safely only with screwed fastening.
What Happens on Removal?
When a screwed connection is removed, a screw hole remains on the profile. The hole diameter is small but it is seen as a mark on the joinery surface. For this reason screw mounting is not recommended for a tenant or temporary use.
After removal the holes are closed with a filler matching the joinery colour; on PVC a suitable putty, on timber a filler and touch-up paint make the mark invisible. This is the price of a permanent connection. In return for sturdiness it leaves a small mark on the surface.
The Technical Side of Screw Mounting
A screwed connection is the safest option in cases where the unit will stay on the same joinery for years. While hooked and adhesive systems carry limited tolerance against time, moisture and carrying load, the screw locks the rail to the joinery profile mechanically and permanently carries the tension cords' continuous load.
The mounting does not ask for a professional crew but asks for the right tool. A thin-tipped drill, a suitable screw and a spirit level. For users who will mount it themselves, the pilot-hole opening and alternating tightening order is provided step by step in the guide arriving with the product.
On large-square-metre living-room and gallery glass the screw is the only reliable option. As the unit weight grows, the adhesive's carrying share decreases. The hook's grip safety drops and the rail stays straight for years only with a screwed connection without sagging.
Common Mistakes in Screw Mounting
The most frequent mistake is driving a screw without a pilot hole: the PVC profile cracks in cold weather, the screw strips and the rail loosens. A pilot hole opened with a thin bit prepares the screw path without splitting the profile.
The second mistake is tightening the rail from one end. If one side is fully tightened and the other connected afterwards, the rail draws an arc and the fabric escapes to one side. An alternating tightening order seats the rail straight.
Missing the steel reinforcement channel is also common. The screw must land not on the profile wall but on the steel channel inside. Otherwise the screw comes out at the first load. The channel's position changes by joinery model and the screw line is marked accordingly.
The last mistake is skipping the sash test. When the mounting is done the job is not handed over before the sash opens fully. If the rail rubs the jamb or side profile the position is corrected at that moment. A rub noticed after use begins scratches the rail surface.
