Why do you need a ventilation facade grille?

Every room, be it an apartment, a residential building or an office, needs a properly equipped and installed ventilation system.

Clean and fresh, constantly renewing air is the key to creating an optimal microclimate in rooms and good human health. If the ventilation is insufficient, then carbon dioxide will accumulate in the premises, high concentrations of which contribute to the active reproduction of pathogenic microflora. Hence - the development of various diseases and poor health of a person.

That is why the entire ventilation system must be carefully thought out even at the design stage of any building. One of its objects is just an external ventilation grill.

So why is this construction needed? To ensure the following functions:

  • good air exchange in all rooms of the building;
  • compliance of the building with fire safety requirements - in case of fire, the grilles will help to draw out smoke and reduce the risk of carbon monoxide poisoning;
  • creation of an optimal microclimate in all rooms;
  • protection of the ventilation shaft from small animals and the ingress of various inanimate objects into it, including debris;
  • ventilation grilles will relieve both unpleasant odor and stale air in the premises;
  • decorating the facade of the building;
  • if there is a facade grill, then the draft in the entire ventilation system will be much better than without this element;
  • the grill will help to facilitate and keeping the ventilation shaft clean, as it collects all dust and soot that is easy to clean off.

With the help of external ventilation grilles, you can also very interestingly beat the facade of the house, decorate it and make it unique, since now on the market of goods for construction there are various types of these structures for every taste, and with different qualities.

Grille arrangement

External ventilation grilles are of different types depending on the material from which they are made, as well as on functionality. According to the way of work, facade grilles are inertial, adjustable and non-adjustable.

Grille type Features and properties

Adjustable

These ventilation grilles are equipped with movable louvers, by adjusting which, the owner of the house can control the movement of air.

This is achieved by reducing the space between the blinds. The main plus is the ability to individually adjust the most comfortable air flow for you.

Non-adjustable

The simplest lattices. They have slats that are firmly attached and unable to move. If you install such a grill in the house, you will not be able to control the flow of air into and out of the house.

Inertial

They have movable slats at the blinds, due to which independently block the ventilation shaft or open it depending on the movement of air masses. True, such grilles work only in one direction and are usually used to remove polluted air from rooms.

The carefully selected grille will easily emphasize the style and exterior design of any building. Fortunately, these facade elements have a lot of variations in shape and color, which will easily allow you to choose exactly the model that will not only provide the house with good ventilation, but also decorate it. After all, it is much better to have on the wall a beautiful, for example, a Gothic external lattice than an ordinary hole in the facade.

And due to the different variations of the grille colors, the ventilation hole can become completely invisible on the wall of the house. This is true if you do not want it to be conspicuous. Also, ventilation grilles can have different shapes - from the usual rectangular to round. It is very convenient for their selection for a specific type of design.

Metal ventilation grilles, scheme

According to the material used for the manufacture, facade ventilation grilles are divided into steel and aluminum.

Let's consider each of the types separately.

Steel grilles

Very durable and often used in building construction, gratings are made of steel and covered with a special zinc coating on top, which increases their service life.

Galvanized ventilation grilles

Their main advantages:

  • Long service life - about 10 years ;
  • high strength;
  • resistance to mechanical stress.

However, if customer reviews are to be believed, steel grilles actually begin to rust before the stated 10-year lifespan has expired. Also, one of the main disadvantages of such ventilation elements is more complicated installation than when installing aluminum grilles, and a large weight.

Adjustable louver grilles

How quickly the corrosion process starts depends on the thickness of the zinc coating on the grill. The fact is that zinc is an element that protects steel well from chemical and electrical influences. And the more its layer on the lattice, the better. The zinc coating begins to wear off almost immediately after the ventilation element is installed, however, until it is completely thinned or scratched, the rust of the grill itself is not terrible.

Aluminum gratings are recognized as the most durable

Some manufacturers of these structures declare that aluminum gratings do not lose their properties and do not require replacement for at least 10 years.

However, there are eyewitnesses that such a design has served without losing its qualities for more than 20 years. But here a lot depends on the conditions in which the aluminum grille was used.

How to choose a grating for the facade

that the ventilation grill will serve you faithfully and at the same time please the eye and decorate the facade of the house with its presence, it is the right choice. Therefore, it is important to take into account the following aspects when designing a building and directly selecting the element itself:

  1. Think about where the outer grille will be located. Try to choose this place so that the structure fits harmoniously into the design of the building.

  2. Depending on the ventilation requirements of the room, carefully weigh the pros and cons of each type of grille and decide which one you need - inertial, unregulated or adjustable. It may well be that it will be unnecessary for you to adjust the blinds.
  3. Pay attention to such aspect as the air section coefficient. It will depend on him how well each room in the building will be ventilated. It is best to opt for a lattice with an index of 1.

  4. Look at the size of the structure. The hole where the grille will be installed must match its dimensions.
  5. Match the structure to the color of the building facade. You should not place the red grid on a green or blue background if there are no additional elements of the same color.

By the way, sometimes lattices of a contrasting color can favorably change and embellish the appearance of a building, but it is better to select them so that they are still combined with other decorative elements.

It is worth remembering that in individual cases or if they are installed incorrectly, ventilation grilles can also become an obstacle to fresh air flows. That is why you should not be negligent in their choice. If you have the slightest doubt, you should consult a specialist.

It is worth remembering that in order to extend the service life of the grille, as well as for its normal functioning, it must be periodically cleaned. You should sometimes remove the blinds and grate and thoroughly wash them from the accumulated soot, dust, insect corpses and other debris. At the same time, part of the ventilation shaft can also be cleaned if there is visible dirt in it.

Based on the above, we can conclude that the ventilation grill is an indispensable element in the construction of any building.
