Select The Right Fixed Louvers

By Janine Hughes


Louvers not only add to the aesthetic appeal of buildings, but also offer a reliable and highly cost effective ventilation solution. They can be used on industrial, commercial and residential buildings. They consist of slats that are angled to keep out rain and let in air and light. Horizontal or vertical options are available. Fixed louvers differ from adjustable ones in that the slats are set in position and cannot be moved. They offer privacy, security, shading, protection against bad weather as well as having a pleasing appearance.

Designs are varied and choice depends on where they are to be used. They come in all shapes and sizes and the spacing between blades is also different. A number of types of material are used for construction. Metal, wood and glass are all used but probably the most utilized material is probably aluminum.

Aluminum has the advantage of having a high tensile strength, is resistant to heat and cold and it does not corrode easily. A number of different options are available when it comes to finishes. A powder coated color finish or an anodized finish are two options.

A louver offers a sustainable yet effective ventilation solution for industrial, commercial and residential buildings. They are also cost effective and ideal where greater weather exposure is experienced. Car parks, factories, apartment blocks and office buildings are just some of the places where they are used. They may also be specifically designed to enhance the facade of a building.

When selecting a product like this, one must select a reputable manufacturer as there are numerous considerations that have to go into the design. Reliability and accuracy of test methods and data concerning performance is important. Free area, water penetration and air flow resistance are factors have to be accurately tested to come up with the optimum design.

A high percentage free area means that the most air possible flows through the smallest opening. How much water is able to penetrate obviously has to be taken into account as well. Air flow is affected by various factors such as the shape, size and angle of the blades. Each product has a slight difference when it comes to air flow resistance. The best manufacturers use the data they collect when testing to ensure that their products are as efficient as possible.

If clients require customization manufacturers are often happy to offer this. There are also various optional extras offered by manufacturers such as fitting an insect screen or some galvanized mesh. Some products already come with gutters situated in front of the blades that help to direct water away from the opening.

A louver is a practical item allowing for increased air flow, diffusion of direct sunlight, protection against the elements and privacy. However, architects are also using them for the aesthetic effects they create as well. They can be used internally and externally and and are available in a great variety of designs. Shopping online offers an easy way to compare designs and prices.
