Selecting The Most Suitable Fixed Louvers

By Janine Hughes


A louver consists of slats that effectively let air and light in but keep direct sunlight, noise and rain out. These slats may be horizontal or vertical and fixed louvers are those with permanently set slats. They are very versatile and may be used to give privacy, protection against bad weather or for shading and security. They can also be used to create a pleasing aesthetic effect.

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.

These products are manufactured from a number of different materials like wood, metal and even glass. Aluminium is a most popular material as it is corrosion and temperature resistant with a high tensile strength. The finishes on these aluminium products are varied and a natural anodized finish, mill finish or a powder coated color finish are all available.

The design requirements of a building have to be taken into consideration when making choices. In factories and other industrial buildings temperature control and natural ventilation are of vital importance. Commercial buildings, car parks, apartment buildings and residential buildings all make use of these products with designs specifically suiting different applications.

It is important to buy these products from respected suppliers. If buying from an online supplier, check out how much experience the manufacturer has had in making these products. It is possible to read customer reviews to find out how other people have experienced their service. They need to test designs accurately and establish exactly how well their designs function. Data has to be collected with regard to penetration of water, air flow resistance and free area.

The free area is the total open area of the louver divided by the overall opening. A high percentage means that more air can enter into a smaller opening, thus reducing overall costs. Another consideration is the water penetration. Minimal water penetration while maximizing free area is most desirable. Air flow resistance of each product is different depending on the type of blades and the shape and angle of a frame. The specific angle at which slats are set can make all the difference when it comes to effectiveness. Many manufacturers state percentages of free area and air flow resistance in product specifications.

Clients may be given the opportunity to customize products. They may be able to choose the size and shape of blades or a particular finish. They may also be able to order extras to be fitted such as galvanized mesh. There are products that already come with gutters fitted in front of blades directing water away from the opening of the building.

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.
