Q&A for Togen Louvre Products

 

Q: What is a louvre?

A: A louvre is a framed opening, as in a wall, door or window, fitted with fixed or moveable horizontal slats for allowing air and light through whilst stopping rain.

 

Q: How do louvres function?

A: Louvres are designed for two apparently contradictory functions: to allow air in and keep water out. The blades provide protection, while the openings allow airflow. For a building such as a car park, ventilation will be more important than protection but, in most cases, the final design will be the result of a carefully considered compromise.

 

Q: What is free area?

A: Free area is derived by taking the total open area of a louver (after subtracting all obstructions - blades and frame) and dividing by the overall wall opening. This gives a comparison of a louvered opening to an unobstructed opening. Common louver free areas range from 35% to 60% of the wall opening (65% to 40% obstructed).

Typically, Percentage Free Area of a louvre is given for a specific size; say 1m x 1m, however, changing the size of the louvre can significantly affect the Percentage Free Area available.

Free area is not the only factor to decide airflow. Mullions, structural supports, bird screens and insect screens will also impact airflow. When specifying louvres, it would be better to focus more on airflow instead of only on free area to attain better ventilation.

 

Q: What types of louvres are there in Togen?

Altogether, there are 4 types of louvres in Togen.

1) Performance (Storm-proof) Louver

Performance Louvre is designed to protect against the onslaught of wind-driven rain, whilst allow the passage of air into the room.

2) Acoustic Louver

Acoustical louvers are designed to be used in any type of building with the requirement to reduce noise from air intake/exhaust openings, from power stations and chemical treatment plants to commercial office buildings or manufacturing plants.

3) Standard Louver

Standard louvres allow the maximum airflow into the room but with lower degree of rain defense. With lower cost, standard louvres tend to be favored by projects where economy is the primary consideration, high free area is important and occasional water penetration will not cause significant problems.

4) Screening Louver

Screening louvre is highly versatile, with a mullion design that accommodates long spans. Plant screen louvres hide unsightly machinery and can enhance the look of a building.
