The construction of a building for any purpose is preceded by a design stage. During the preparation of the project, ventilation, air conditioning, heating, sewerage and other engineering systems are being developed. The ventilation system is responsible for the supply of fresh air from the street and for the removal of exhaust air masses from the premises. The ventilation consists of an air duct that goes outside. To decorate the hole and improve the appearance of the facade, the facade ventilation grilles are used https://redvent.ru/catalog/fasadnye-reshetki/. They also prevent foreign objects from entering the air ducts - stones, branches, leaves and other debris. By installing such gratings, the facade looks more harmonious.
Functional purpose of outdoor ventilation grilles
Facade gratings in the overall architectural complex perform not only a decorative function. In practice, these designs solve a number of important problems:
- ensuring a uniform supply of air masses inside the room;
- air flow regulation;
- UV protection;
- quick smoke removal in case of fire;
- eliminates the penetration of foreign objects into the air ducts - effective protection against serious damage to the installed equipment.
Products of various modifications are on sale, which are selected taking into account the characteristics of the building, the use of individual premises. The grilles consist of a metal base, which increases their strength, reliability, and extends their service life. The composition also includes lamellas and fasteners. The base is most often made of aluminum alloy or galvanized steel. Such models are not afraid of snow, heavy rains, sudden temperature fluctuations. The dimensions and shape are selected taking into account the dimensions of the ventilation opening.
How to choose the right ventilation grill for the building facade?
Installation of protective structures on the walls of the building is carried out after the completion of the rough work. Replacement may be required if the facade design is worn out or changed. When choosing, pay attention to the following characteristics:
- lamella mobility;
- sizes;
- the form;
- material of manufacture;
- air section coefficient.
Blinds adjustment is a useful feature. By adjusting the position of the lamellas, it is possible to direct air currents to certain parts of the room. It will come in handy in both residential and commercial spaces. The shape and dimensions are selected taking into account the dimensions of the ventilation opening. For this reason, it is worth picking up the gratings after the completion of construction work, after the laying of engineering systems. The color of the product must match the appearance of the walls. Manufacturers offer a wide range of products, so you can choose the right option for any architectural solution.
An important selection criterion is the cross-section ratio. This is the ability to pass a certain volume of air. If this value is close to one, then ventilation will work efficiently. To calculate the coefficient, you need to divide the volume of the opening by the volume of the opening area. You can also consult about the choice with the employees of specialized stores, who will provide complete information about the model you are interested in.
