Types of ventilation grilles: brief descriptions

Ventilation openings in the rooms in use are made to be closed with special grilles that perform several important functions. To date, manufacturers offer a huge selection of such products, differing in shape, material, purpose, and other characteristics.

In this article we look at their most common types.

General provisions

Arrangement of ventilation allows you to create an optimal microclimate for a person in the room by ensuring the effective circulation of air masses. In this case, all the exhaust air is removed to the outside through the exhaust system, and the new one enters through the air inlets. This happens according to two principles:

Tip: in buildings with a large area, it is recommended to equip mechanical ventilation, since the natural simply can not fully cope with the task assigned to it.

And if most of the ventilation of a house or apartment remains hidden from prying eyes, then the grilles are the first visible components of the entire system, performing their own set of functions and having a lot of variations.

The first difference to which you should pay attention is the area of ​​their application:

Popular options

Now let's take a look at the offers that take place in specialized stores.

Intake

Outdoor ventilation grilles have several options:

1. The gable ventilation grille is most often installed on the attic window when airing the roof and upper rooms, have a wide relief edging on automatic latches and favorably emphasize the overall design of the whole house.

1. Ventilation grille for the basement is used in cases where the system originates in the basement of the building. In this case, a slightly different goal is pursued than in the case of the previous option, since invisibility and maximum protection from rodents come out on top.

1. The ventilation grille will be an excellent solution if it is too expensive to make a hole in the wall. In this case, the elegant design is mounted directly into the entrance and interior doors, ensuring sufficient inflow and distribution of fresh air.

Tip: if your house has very thick walls, then it is recommended to install the inlet openings right in the door, closing them with the gratings described. This will allow you to significantly save on installation work.

1. Ventilation grilles for the floor are used again in those cases where the ventilation system originates in the basement and is further carried out not by means of a pipe, but by creating appropriate openings.

Exhaust

1. Louvre ventilation grille is incredibly comfortable with a natural indoor air circulation system.. Thanks to the ease of changing the flow area, you can easily adjust the duct capacity: an empty room - shutters closed so as not to let out too much heat, many people opened it to enhance the output flow.

1. Ventilated closing grilles, in fact, have the same advantages as the models described above, but only limiting the capacity of the air duct is solved by special valves.

1. Ventilation slotted grille is used for arranging not only exhaust, but also supply points. Their design allows you to hide the presence of the ventilation system.

1. Overhead ventilation grilles are a simple panel with the required number of holes, which is mounted directly on the exhaust opening with self-tapping screws or glue.

Forms

The shapes of the products under consideration can be very diverse: round, oval, square, rectangular, or even polygonal. Moreover, if we are talking about hoods, then they are strictly tied to the outlines of the cross section of the ventilation ducts.

Here, by the way, one more feature can be noted: square and rectangular sections more rationally consume the occupied space, but form inside the vortex flows that interfere with the movement of exhaust air.

But for the supply grids the instruction is not so strict. Firstly, the hole itself can have different shapes, and secondly, there is usually enough space for mounting even the most intricate models.

Materials

The most commonly used one of two materials:

1. Metal.

Pros:

• High strength to withstand significant mechanical damage.
• Attractive appearance.

Minuses:

• Tendency to corrosion processes.
• High price.
• The heavy weight demanding reliable fixing in the course of performance of installation works.

1. Plastic.

Pros:

• Low cost.
• Striking imitation properties. You can pick up products made under stone, steel, brick, wood and other building materials.

• Ease of installation work.
• Lack of hydrophobicity.

The minus is the relative low strength. Careless handling or deliberate mechanical action can cause significant damage to the plastic model.

Conclusion

Ventilation grilles allow you to complete the installation of ventilation and make its visible part more attractive. A huge variety of such products will help you choose a model that fits perfectly with the design and interior of your home.
