Customer’s first point of focus


When the end user operates the window, where is their attention focused first? On the handle.

You could say that the handle is the user interface of your window. It is like the dashboard and controls of a car, or the operating system of a smartphone or tablet.

GSW takes the time to get their user interface right in terms of appeal, ease of use and functionality.


How does it make people feel?


Think about how people appraise the user interface of a car. They comment on the look and quality of the interior, how clearly laid out controls are, the response of the steering. Ultimately, it is about emotion: how it makes them feel.

It doesn’t matter how reliable or economical the engine is, how much space is in the boot or how good the car looks. Get the user interface wrong and the manufacturer has made it much harder to get a sale and create a truly satisfied customer who will stay loyal.


It’s the same with every product


It is the same with every product. People choose their smartphone because the user interface works for them. They may prefer to type on screen, or to have a physical keyboard. They may find one operating system more attractive and easier to use than others. Steve Jobs was obsessed with getting the user interface right.  Manufacturers who have paid less attention to this area haven’t usually sold as many phones and tablets as Apple.

So what can GSW offer you to enhance the user interface of your European window?


Designed with the user in mind


For European Tilt&Turn windows and balcony doors, there are four distinctive collections within the Roto handle family. Each has its own style, and all of them have been designed with the end user in mind, paying attention to the look, feel and functionality.

As you’d expect, GSW window handles are designed to comply with all relevant US standards for quality, security and safety. They are made from aluminium rather than die-cast materials, and they are available in a range of finishes and locking options.


More than a means of opening


At GSW  we see a handle as more than a means of opening and closing. It is also an aesthetic feature and an enhancement to the security and usefulness of the window.

An important security consideration is preventing the handle from moving if the window is manipulated from outside. For example, an attack on a window frame may make part of the hardware accessible. If the intruder is able to move the hardware mechanism, it might be possible to disengage the locking points and open the window.


Three ways to secure a handle from outside


A handle with a locking mechanism prevents this. GSW offers three different ways to secure a handle.

There is the traditional push button locking option. The handle cannot be moved until the button is pressed. This can work well in many situations. However, you might not want a push button – perhaps for aesthetic reasons.

In this case, the GSW LOCKING option is worth considering. Handles with this function give “invisible protection” against outside manipulation. This is achieved by a specially-designed clutch mechanism. The handle has no visible button or lock. Any person inside the building can operate it, but movement via the hardware mechanism is blocked.


Restricting who can open the european window


There may be times when you want to lock the handle completely, or perhaps restrict who is able to open the window. A key locking mechanism is ideal for this. Standard GSW handles with key locking cylinders resist a torque of 40 NM. However, higher security versions are also available. These have been tested to resist a turning force of 100 NM.

There is also another, very useful variation on the standard key-locking handle. It enables you to transform a European Tilt&Turn window into a Tilt-Only unit when required. This is especially important for child safety, or indeed for protecting hotel guests.


Child safety


The tilt-first lockable version of a handle works in conjunction with a tilt-first hardware system. It looks like any other key-locking handle. The first 90 degrees of movement is available to all users – allowing them to tilt the window and ventilate the room. However, only key holders are able to move the handle to the 180 degree ‘turn’ position and open the window fully.

In the home, parents can retain the key, allowing children to tilt the window but never open it far enough to create a safety risk. In a hotel, the key can be held by maintenance staff. Guests can ventilate their rooms but not open the window in ‘turn’ mode.


We work only with the best : ROTO


FOUR distinct styles


Those are the functions. How about the styles? Let’s have a look at those four different designs.

RotoLine is the classic Roto handle. With a straightforward design featuring clear lines, this has been a core product for Roto and a popular choice among customers for many years now. The handles are also available in left and right-hand cranked versions for use on Open-Out window designs.

RotoSwing is the modern handle, designed to bring an extra bit of design flair into the contemporary home or office. RotoSwing handles are available with the same security and functionality options as the rest of the range, and are just as easy to operate. Their distinctive feature though is that curved shape.


The new addition – RotoSamba


Roto Samba is the latest addition to the family. Marketed as “the classic modern handle”, it is designed to strike a perfect balance between traditional and modern aesthetics.

Samba fits in with the widest range of ages and styles of buildings. It is fresh enough to be seen in the most modern interiors, and you could also put a Samba handle into any home made in the last few decades and it would not look out of place.

When you grip the RotoSamba handle, you’ll notice that care has been taken to accommodate your index finger in the most comfortable way. It gives that feeling and assurance of attention to detail.


A full range of finishes


As with the other handles, RotoSamba is available in push-button, key-locking and tilt-first locking options, and in a range of anodized and powder-coated finishes:

Silver, anodized
Brass matt, anodized
Titanium-matt, anodized
Bronze, anodized
RAL 9016 Traffic-white
RAL 8019 Grey-brown
