Architectural Screening & Ventilation

Our extruded aluminium profile systems of 'blades' and brackets can be configured for use as robust privacy or security screens, and also as ventilation panels for plant rooms. Used in these applications, the elliptical blades can be mounted either in a vertical 'ladder' arrangement, or stood up on end vertically for a different effect.

Continuous Plant Room Louvre Walls

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.

Plant Room Doors

Louvre doors are designed to either be stand alone units, or to integrate into a continuous louvre wall solution.

Consisting of an outer frame, and a hinged inner frame which forms the door itself. The inner frame has the louvre blades mounted on it and houses the door handle mechanism, locks etc.

If the door is integrated into a continuous louvre wall, then design is such that it forms an almost seamless part of the wall. Louvre doors can open inwards or outwards depending on specific requirements.

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. 

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

Vertically Mounted Sliding Ladder Panel

A variation on the vertically mounted ladder system, this stand-alone panel is designed to sit in front of floor to ceiling windows. The panel sits within a frame that allows it to slide left and right across the window and is ideal when only partial shading is required.

This panel can be fabricated up to 3 metres in height, and at widths to suit the clients requirements. The panel can be moved to allow for glass cleaning, which means that it can be fitted very close to the face of the glass if required.

This system uses 60 mm elliptical blade, making this a very slim panel ideal for domestic use. The panel slides on high performance low friction pads which avoids the use of roller bearings or wheels, greatly increasing the reliability of the sliding gear.
