Ventilation Louvres
The Levolux Ventilation Louvre System is versatile in that it can be engineered and designed to suit all types of buildings - for plant screens, weather exclusion and ventilation purposes. As well as enhancing the external appearance of a building and providing an architectural feature the system has a very functional purpose.
The system has three standard sized louvres, 50, 75 and 100mm together with various mullions and frame sections. Its all aluminium construction and unique clipping system remove the possibility of a bi-metallic reaction and “staining” on building façades.
Features and Benefits of Ventilation Louvres
- Aesthetically pleasing – the contoured aerodynamic shape with inherent strength capability has a distinctive profile, whilst still retaining a continuous appearance.
- Virtually maintenance free - its unique patent pending all aluminium louvre to mullion clip assembly and A4 stainless steel fasteners, ensures eradication of any bi-metallic reaction.
- Reduces energy costs - as the blade is aerodynamically efficient, it has the best coefficient of discharge on the market for an extruded blade, and is more effective than even the well-known roll formed version. With air resistance being reduced through the louvre, it allows the aperture and plant equipment to be smaller so saving capital outlay and running costs.
- Flexibility - the system is designed to be fitted with the maximum flexibility utilising stainless steel M8 fixings/fasteners for use with stainless steel universal fixing brackets. This combined with the high strength of the blade allows easy and quick installation with large tolerance capacity within the aperture.
- Performance - the system has the most aerodynamically efficient louvres available on the present market with an extremely impressive free area (maximum incidence). It is also remarkably weather efficient together with the coefficient of discharge which, until now, was thought to be impossible. The aperture for air intake is smaller and accordingly the amount of water entering the system is less than any other single blade, with a similar coefficient of discharge. Indeed the 50mm Contour blade is better than some manufacturers double bank systems.
The Range of Ventilation Louvres Options
The louvres can be used as a solar control feature. Acoustic louvres are also available to meet the various building requirements, they help reduce sounds that are directly admitted into the building as well sounds that are reflected and airborne. For areas where a high degree of weatherability is required our ‘sandtrap’ louvres are available.
The range of accessories for the louvres include insect mesh, doors, flashings, backing and insulation panels. A range of finishes are available - anodised, mill finish or powder coated to any RAL colour.
System Construction
- Mullions - the mullions are fixed back to Levolux stainless steel adjustable brackets at around 1200mm centres. There are four different types of mullion available. The strap mullion, standard mullion and a deeper high span mullion which allows the louvre system to span greater heights in many cases eliminating the need for secondary steelwork. The ‘box’ mullion is particularly suitable for corner details.
- Louvres - the aluminium extrusions are important in that they create crisp lines and can be made into complex shapes required for a good louvre system.
- Clips - the unique all aluminium tension clip system has the clip fitted into the slots and locked under the clip above. Once positioned the clip becomes fixed. Only one mechanical clip to mullion is required.
- Fixing Brackets - stainless steel fixing brackets with slotted holes to overcome small tolerances, both horizontally and vertically.
- Flashing - fabricated aluminium flashings formed to encase the louvre system and form a weather seal around the perimeter of the louvre.
