Silent Gliss 3840 - Corded Metal Curtain Track

The Silent Gliss 3840 Corded Curtain Track combines discreet styling with the convenience of cord operation, making it a particularly useful choice for larger windows, bay windows and curtains that you would prefer not to handle each time they are opened or closed.

Rather than pulling directly on the curtain fabric, the curtains are operated using the cord system. This provides controlled movement while helping to reduce unnecessary handling of the curtain itself.

With a maximum system span of 6 metres and a maximum curtain weight of 14kg in appropriate configurations, the SG3840 sits within Silent Gliss's medium-to-large curtain track range. Actual curtain capacity depends on the track length, shape and glider arrangement, so shaped and bay-window installations may have a lower maximum curtain weight.

Made to Measure for Your Window

Every SG3840 is supplied made to measure, allowing the system to be specified around the dimensions and layout of your window.

For bay windows and curved spaces, the 3840 is bendable and can be shaped using our professional bending services and excellent craftsmanship. This provides a far more considered solution for windows where a standard straight curtain rail simply won't follow the architecture of the room.

Ceiling or Wall Fixed

The Silent Gliss 3840 can be either ceiling fixed or wall fixed, giving you greater flexibility when planning the position of your curtains.

Ceiling fixing is particularly effective where you want the curtain treatment to sit close to the ceiling and create a clean, understated finish. Wall fixing provides an alternative where the ceiling is unsuitable or where the position of the window requires the track to project away from the wall.

The choice isn't simply aesthetic, the structure around the window, required curtain position and available fixing surface should all be considered when deciding how your track will be installed.

Designed for Bay Windows and Curved Spaces

One of the most useful features of the SG3840 is its ability to be professionally bent for bay and curved window applications.

Getting a corded track right around a bay requires more than simply choosing a bendable profile. The shape of the track, curtain weight, overall dimensions and position of the bends all affect the finished system.

Our made-to-measure service allows your measurements to be checked before the track is prepared, helping to create a system designed specifically for the window rather than asking you to adapt a standard track on site. For help and guidance on how to measure visit our bay window measuring guide.

Standard or Wave Curtains

The SG3840 uses Silent Gliss 2-component (2C) glider technology and is also compatible with the Silent Gliss Wave curtain heading system.

Wave creates a regular, flowing curtain formation and is particularly suited to contemporary interiors where the appearance of the curtain heading is an important part of the overall window design.

Your choice of glider and curtain heading should be considered when the system is specified, particularly for shaped tracks, as the configuration can affect the maximum recommended curtain weight.

Why Choose Cord Operation?

A corded track can be particularly helpful for tall windows, larger curtain installations or curtains that are difficult to reach comfortably.

Because the curtain is controlled from the operating cord, there is no need to repeatedly pull on the leading edge of the fabric. It offers a practical middle ground between a hand-drawn track and a fully electric curtain track.

If you're unsure whether a hand-drawn, corded or electric track would work best for your window, our team can help you compare the options.

FAQs

Is the Silent Gliss 3840 suitable for bay windows?

Yes. The SG3840 is a bendable curtain track and can be professionally shaped for bay windows and other curved applications. Because curtain capacity varies according to the length and shape of the system, we recommend specifying the complete bay layout rather than relying solely on the headline maximum curtain weight.

Can the Silent Gliss 3840 be ceiling fixed?

Yes. Silent Gliss confirms that the 3840 can be ceiling or wall fixed, allowing the fixing method to be selected to suit the window and surrounding structure.

How much curtain weight can the Silent Gliss 3840 carry?

Silent Gliss specifies a maximum system curtain weight of up to 14kg, but this is not the appropriate limit for every installation. Capacity varies according to the track length, curtain draw, number and shape of bends and the glider system selected.

This is particularly important when specifying the track for a bay window.

What is the maximum length of the Silent Gliss 3840?

Silent Gliss specifies a maximum system span of 6 metres.

Is the Silent Gliss 3840 suitable for Wave curtains?
Yes. The SG3840 is compatible with the Silent Gliss Wave 2C system, making it suitable where you want the regular, flowing folds associated with a Wave curtain heading.

Why choose a corded curtain track rather than a hand-drawn track?
Cord operation allows you to open and close the curtains without pulling directly on the fabric. It can therefore be particularly useful for taller windows, larger curtains and installations where the curtains are less convenient to reach.

Can I wall fix the Silent Gliss 3840?
Yes. Wall fixing is available as well as ceiling fixing. The most appropriate method will depend on the construction around your window and where you want the curtains to hang.

Will I see the track above my curtains?
The amount of track visible depends partly on the curtain heading, hook position and how the system is installed. These should be considered together when deciding the final position of the track.

Is the cord mechanism visible?
The 3840 is a cord operated system. The precise visibility of individual operating components depends on the installation and configuration, so I would avoid promising that the entire mechanism is invisible.

Can I get a colour sample before ordering?
Yes, if you would like a sample, reach our to our team who would be more than help.

What happens if my track is damaged in transit?
Contact our team and we will arrange a replacement where the track has been damaged in transit.

Does the Silent Gliss 3840 require much maintenance?
No specific maintenance requirement was confirmed in the information reviewed for this rewrite. Follow Silent Gliss care and maintenance guidance for the system rather than applying lubricants or treatments that have not been recommended by the manufacturer.
