As the name suggests, this is the method by which walls can be created from a combination of rows of vertical mullions with louvre blades clipped to them. Common uses of continuous louvre walls include creating plant rooms and creating visual screens on the upper levels of buildings. Continuous louvre walls are generally fabricated from the larger pitch louvre blades, typically 75 mm or 100 mm.

Continuous louvre walls often incorporate louvre doors as part of the system. Latest generation louvre walls use elliptical louvre blades rather than the more traditional “Z” profile blade. Typically available in 60 mm, 120 mm, 145 mm and 200 mm blade widths, and designed to maximise the throughput of air from one side of the wall to the other, these systems offer a typical free area of between 40% and 50%, making them viable, cost effective alternatives to “Z” blade systems.

Data Hall Cooling / Security Walls - Case study

Client:  Internet Service Provider

Requirement: Data Hall Cooling Walls

Overview: The client has built six data halls within a secure premises. Each data hall was required to have floor to ceiling louvred walls which run the entire length of the rooms. In total over 600 m2 of ventilation louvre walls.

The solution: Aluminium Systems Ltd installed heavy duty box sections to create a framework of vertical and horizontal supports. Each framework standing over 5 metres high and with widths of up to 40 metres, fixed to heavy duty steel uprights, and bolted to the floor. This framework formed the basis of each of the systems, which consisted of vertical mullions carrying 30 x 145 mm wide elliptical blades at 100 mm centres.

The challenges: Three of six data halls were on the ground floor, with remaining three immediately above them. The louvre blades were each supplied at a length of 7.5 metres and then trimmed to exact size in situ. This meant that a total of 900 blades were supplied to site, of which 450 had to be brought up to the first floor by telehandler and then manoeuvred by hand into position. The supply, delivery and safe storage of the blades required careful logistical management and clear and accurate communications between the site management, the installation team and the delivery company.

Each of the data halls required a carefully planned timetable of events to ensure that the delivery and installation of the framework, louvre blades and flashings occurred at the correct point in the overall project timeline. Working closely with other trades, such as flooring and ceiling fitters, electricians and air conditioning engineers, our fabrication, delivery and installation teams were able to ensure “just in time” delivery and fitting.

The project was delivered on time and within budget.

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.

Sun-Tracking Photo Voltaic Louvres

Motorised Sun-Tracking Photo Voltaic Louvres

This product is specifically designed to perform two jobs. Firstly to offer solar shading throughout the day to glazing mounted underneath the system, and secondly to generate power by means of photovoltaic cells built into the louvre blades. The louvre blades are created from aluminium frame profiles which hold solar panels which are made up from the photovoltaic cells.

As the sun passes overhead from east to west during the course of the day, the on board sun tracking computer controls an electric actuator which moves the louvre blades so that they are allows facing the sun. This offers maximum shading to the glass below, and also ensures maximum power is generated by the p v cells.

The power is transmitted from the cells via in built cables to the pivot of the louvre blade, which is hollowed out to allow the cable to pass through it and out to the DC to AC invertor array. From here the AC voltage is distributed into the mains supply. At sunset the tracking computer commands the system to reset all of the louvre blades back to the starting position, ready for the next sunrise.

Vertically Mounted Ladder Screening

Vertically mounted systems offer a high degree of solar shading in certain circumstances, but can also offer security and privacy functionality. Although generally offered as a fixed blade system, vertically mounted ladder systems lend themselves quite well to being motorised, offering a more comprehensive level of screening, and allowing the customer to adjust the blade angle.

Vertically mounted ladder systems are quite often used to shade runs of curtain wall, particularly in commercial buildings that have large areas of glazing such as car showrooms, office blocks or in schools. The blade size, pitch and angle will determine the amount of shading in any given situation.

Fixing this type of system to a run of curtain wall needs to be planned well in advance, as the mounting brackets have to be incorporated into the curtain wall mullions before they are installed.
