Louvred Fire Escape / Security Door

Client: Developer, Accra, Ghana.

Requirement: To enclose seven storey fire escape.

Overview: The developer, who is a long term client of Aluminium Systems, built a substantial office block incorporating a ground floor car dealership, and his own head offices on the seventh floor. He considered that the building would be enhanced by the fitting of louvre blades around the entire fire escape, plus further runs of continuous louvre walls to hide roof mounted water tanks and to provide privacy to the penthouse office suites.

Solution: A three sided louvre wall was constructed using 145 mm wide elliptical louvre blades, running from ground floor to seventh floor, with fire escape doors incorporated on the ground floor. This part of the system was bolted back to the steel fire escape, whilst the privacy and sight screens were fixed back to modified existing structural steel frame. Please see the additional images for the integrated louvred fire escape door with one-way operation for security and integrated pull bar which was manufactured with eliptical blade to match the louvre wall.

Challenges: The major challenge with this project was the fact that the installation was complex and unusual, and 4,500 miles away. Aluminium Systems shipped the system in ready-made sub-assemblies, all carefully wrapped, identified and labelled. Then a two man team attended site once the materials had cleared customs, and spent two weeks supervising the initial part of the installation. Once satisfied that the local work force were sufficiently experienced, they returned to the UK, and the total installation was completed within the following six weeks.

The building, called The Grand Oyeman, is now a well established landmark in the business district of Accra, and the louvre walls covering the fire escape are floodlit at night.

Testimonial:

"Nowak Developments Limited is a Property Development Company in Ghana and we have used Aluminium Systems for all of our solar shading and screening requirements for the past seven years. We are not just a satisfied customer but, a very happy one at that. We are happy with the quality of their products, attention to detail and customer service in general and strongly recommend them"

Vertically Mounted Screening Blades

In this configuration, the louvre blades are stood “on end” and built into a frame which stands off a little way from the building (this allows for access to the glass for cleaning). This type of shading is often used when an architectural feature is required to shade a floor to ceiling window, it is generally offered as a fixed blade solution. However a motorised version of this system has been successfully deployed across a number of branches of a high street bank in Ghana

Brise Soleil Horizontally Mounted Canopy

The most popular of all Brise Soleil configurations, horizontally mounted canopies are generally mounted immediately above the glazed area that they are shading. Most horizontal canopies have a projection of between 500 mm and 1,500 mm, which is generally more than adequate to shade the windows or doors below. Options include joining a number of canopies together to form a continuous run, corner units, and overhead support arms.

The brackets that fix the canopies to the wall can either be fixed to the structure before render is applied (generally the case on a new build) or in the case of retro fitting to existing buildings, can be fixed to the external finish. In both cases the brackets are powder coated to match the rest of the system.

Motorised Brise Soleil

Motorised Brise Soleil - when should motorised BS be considered?

For many applications, a fixed blade system provides all of the functionality required by the client. For example, if the system is being used primarily as privacy screening, or as an architectural feature, then a fixed blade system is almost always the preferred solution. Even when solar shading is the primary objective, this can still very often be achieved by the use of a fixed blade system. With lower costs, simplified installation and no moving parts, a fixed blade system offers most customers the best balance of functionality against price and ease of use.

There are however circumstances when an adjustable blade system provides more consistent solar shading across the whole of the day, and throughout the year. If such a system is required, then the blades are mounted on pivot points at each end, joined together with a connecting rod, and moved by means of an electric actuator (a motor that moves the connecting rod backwards and forwards). The amount of movement and the direction of rotation are usually controlled by a hand held wireless controller, rather like a TV remote control. However, if required a third party automated system, such as a BMS (building management system) can be linked in to control the motor automatically.
