Electric sliding windows in glass and aluminium are claimed to provide a high level of safety for personnel via features such as automatic locking.  Research carried out by the Swedish Industrial Health Service has also shown that the risk of personal injury is reduced when windows are electrically, rather than manually, powered. The windows, which open either horizontally or vertically, can be used in locations such as banks, post offices, ice-cream parlours, or reception areas.

These windows have been designed and developed by the Swedish company Svalson, and are tailored to customer requirements. Great emphasis has been placed on ergonomics and safety, according to Göran Carlsson, Sales Manager for the company.
‘The Industrial Health Service study showed that electric windows clearly reduced the risk of wear damage to shoulders’, he explains. ‘Vertical sliding windows have counterweights, anti-drop protectors, and friction clutches, which eliminate the risk of jamming limbs. An advanced locking function makes it impossible for an attacker to force open a window violently. And windows can be connected to smoke or fire alarms, so that they close automatically if the alarm is activated’.
The windows come in sizes from 300 x 600 mm to 6 x 6 m, and are operated either by a control panel or a foot-switch. Powered by a 24-V supply, the windows can be set in either steel or aluminium, and be fitted with all types of glass, including curved, fireproof, and bulletproof glass. The motors and other components are built into the frame and the installation of the electric windows, which are supplied complete with all electrical components, is claimed to be simple. The system is maintenance-free, and neither lubrication nor adjustment is necessary.

Bringing the outdoors inside
Svalson has also launched a new vertical sliding glass system in aluminium for places such as restaurants and cafés. The built-in motors have a capacity for lifting 150 kg per moving part, which makes it possible to open up a complete facade. This gives an impression of bringing the outdoors inside, and, according to the company, has not been possible with earlier systems for opening glass facades. Insulating glass is standard, and the system comes in both electrical and manual variants.
‘This new product is called Njord, and is made in any size up to about three metres wide and six metres high’, explains Göran Carlsson. ‘but the profile dimensions are only 80 x 115 mm. In Germany, the system is often used in restaurants with large facades, but it can be used just as easily for smaller bars, kiosks, and food stalls, as an alternative to serving outdoors’./ins


Footnote: Sliding windows installations include Mövenpick in Berlin, Patek Philippe in Geneva, and Maidstone Hospital in London.

Captions: The vertical window is used in applications such as kiosks and ice-cream bars, and comes in widths up to 3 000 mm. The window locks automatically when closed.
