Maintaining a favorable indoor climate is impossible without an inflow of fresh air. Insufficient ventilation leads to the accumulation of carbon dioxide, creating favorable conditions for the reproduction of pathogenic pathogens.
This can be prevented by competently equipped ventilation, thought out to the smallest detail at the design stage. The most important element is external metal facade ventilation grilles that perform many functions.
Purpose of the structure
Ventilation grilles are responsible for:
ensuring the optimal level of air exchange;
smoke removal and reducing the risk of people being poisoned by combustion products;
creating a favorable microclimate in the building;
protection of the mine from rodents, debris, pests;
getting rid of stale air, as well as unpleasant odors;
improving the draft of the ventilation system;
maintaining the cleanliness of the ventilation shaft, since they collect dust and soot on themselves, which are then easily cleaned off.
The attractive and laconic appearance of the gratings allows you to effectively beat the facades of buildings.
Varieties
External metal ventilation grilles are made of various materials, they are of the following types:
Adjustable. Equipped with louvers, the position of which adjusts the direction of the air flow. The planks are brought into action by reducing the distance between them. The main advantage is the ability to direct the flow in the desired direction.
Unregulated. They differ in the simplest design. The bars are fixed in a stationary state. It is not possible to adjust the position of the louvers, which limits the possibility of changing the direction of the air.
Inertial. Unlike adjustable ones, they have movable bars that move in the direction of the direction of air masses. Such structures are mainly used for the outflow of polluted air.
Steel and aluminum gratings are considered the most durable. The declared service life of ten in practice can be up to twenty years. Depends on the conditions under which the ventilation is operated, that is, the purpose of the building where it is mounted.
The designs are presented in a variety of colors, are made in standard and non-standard design options. Unusual Gothic lattices give the building's façade a unique look. On sale are rectangular, round products. The range of market leaders allows you to choose a grille for any ventilation shaft.
