Grilles for ventilation, types of ventilation grilles, how to install the ventilation grill

Calculation and quality installation of the ventilation system in the house necessarily includes work on the installation of ventilation grilles. Among developers there is an erroneous opinion that the ventilation grid performs strictly decorative function, closing the ventilation ducts. Of course, this is a great error. If there are supply air in the house http://vent-market.com.ua/pritochnye-ustanovki, then in this case, the ventilation grilles really perform a decorative function, so as not to disturb the interior of the room. What functions are performed by the ventilation grilles, types of gratings, materials of manufacture, installation methods - all this we will consider below.

Why do we need ventilation grids?

The main task of the ventilation grilles is to ensure high-quality air exchange in the room due to the correct distribution of the air flow and its supply to the required volume. Therefore, ventilation grilles are installed in accordance with fire safety rules, compliance with which is mandatory for all types of buildings and structures. In the event of a fire, the ventilation grilles help to remove smoke from the room and reduce the likelihood of carbon monoxide poisoning.

Types of ventilation grilles

In the modern market there is a wide choice of ventilation grilles, differing in shape, size, design and color solutions, material of manufacture, and, of course, cost.

There are at least four major and several minor factors, according to which ventilation gratings are classified.
  The main factor by which ventilation grids are classified is the way and place of their installation. Accordingly, the gratings are divided into:

• Flow.
  • Internal.
  • Outdoor.

External ventilation grilles, as the name implies, is mounted on the exterior of buildings and structures.

The main purpose of this type of grilles is to protect the openings of ventilation ducts from debris and atmospheric precipitation, as well as the penetration of rodents, birds and insects. For the manufacture of external gratings, the most durable aluminum is resistant to the environment and ultraviolet. Such gratings are necessarily completed with blinds, which are fixed at the right angle. Sometimes the blinds are equipped with a heating function that prevents the formation of ice in the cold season.

Internal ventilation grilles are designed for much smaller loads, it is external, as installed directly in the building.

Therefore, they are often made of durable plastic. Lattices of this type have an attractive appearance, they are compact, a large selection of colors and shades allows you to choose a model that is optimally suited to a particular room.

Internal ventilation grilles are very easy to install and operate. Often, such grids have a removable interior or louvers that can be adjusted at a certain angle, thus changing the intensity and direction of the air flow.

Ventilation grilles are mounted in walls, doors and interior partitions.

In addition to direct use, the grilles also connect two rooms, providing air exchange, light and sound insulation. All grids of this type are equipped with V-shaped blinds, which are arranged in such a way as to overlap each other.

All grids, depending on the type of construction, are divided into:

• Ventilation grilles are adjustable.
  • Ventilation grilles are not adjustable.
  • Inertial gratings.
  • Decorative ventilation grilles

Adjustable ventilation grilles are equipped with movable blinds, by means of which it is possible to adjust the air flow at any time.

Unregulated grids are solid, without blinds, therefore, it is impossible to regulate the air flow with such a grating.

An inertial air grille with a non-return valve automatically closes when the airflow stops.

Decorative grilles can be made of metal, plastic or wood. They are installed indoors and, in addition to performing their immediate tasks, serve as a decoration for the interior of the room. Some gratings made of wood, brass, copper and stainless steel are real works of art. The price of such products is appropriate.

Depending on the material that was used to make the grid, all models are divided into:

• Aluminum.
  • Plastic.
  • Steel.
  • Wooden, etc.

Qualitative plastic ventilation grilles are not exposed to corrosion, mold and fungi, they are light, practical and inexpensive. However, under the influence of direct sunlight, plastic can eventually warp and change color.

Aluminum grilles are strong and light, not exposed to ultraviolet, corrosion and microorganisms, but their cost, compared with plastic, is much higher.

Ventilation grilles made of wood are installed only indoors. Wooden models are completely ecological and very attractive in appearance.

This allows them to fit into the modern interior. It should be noted that such grids are made of solid wood, which require special care and periodic cleaning, and the cost of wooden ventilation grilles is quite high.

The metal ventilation grilles are characterized by high strength and high weight, their cost is an order of magnitude higher than that of aluminum models. The shape of the ventilation grilles can be round, rectangular, oval, etc.

The most popular models of ventilation grilles

Below we consider the most popular models of ventilation grids and how to install them.

rectangular plastic intake and exhaust grilles

Most often mounted on walls or ceiling. Designed for the transfer and rational distribution of indoor air, as well as decorating the ventilation openings of public, industrial, residential buildings and structures.
  The material of manufacture is high-quality durable plastic. The design of plastic gratings contains many additional auxiliary parts: the inner part is fixed to the base by means of latches. Thus, the grating can be cleaned without resorting to its dismantling. Plastic grilles are fixed with screws or screws.
  Plastic models are sometimes equipped with inclined lamellas.

exhaust plastic grilles

Installed outside the building. Designed for decoration of ventilation holes. Material of manufacture - strong plastic of high quality. The design provides a large number of auxiliary elements. Exhaust plastic grilles are equipped with special gravitational blinds, which exclude the appearance of reverse thrust. Mounted with screws or screws.

ventilation grilles for connecting the kitchen hood with a flexible duct

It is designed for the discharge of combustion products in a kitchen or other room equipped with a gas stove.
  Produced from high quality durable plastic.

The design provides for the presence of deviators, preventing the occurrence of reverse traction through the ventilator located below. The detachable lower part of the grate allows cleaning it with minimal time and effort. Mounted with screws or screws.

ventilation door rectangular grilles

Are intended for rational distribution of an air stream between premises. Are installed in the doors of the premises of kitchens, bathrooms, bathrooms, etc. They are also installed in the window sills for free passage of warm air from central heating batteries.
  They are made of high quality plastic, they have a lot of color and design solutions. The design provides the presence of a mosquito net or a damper to control the air flow. Mounted with self-tapping screws directly to the door leaf or window sill.

metal ventilation gratings

They are used for decorating the openings of ventilation and heating systems, air conditioning systems, as well as for rational distribution of air flows. Mounted on the ceiling or wall inside buildings and structures.
  Are made of high-quality steel grades and high-strength aluminum. Designed for painting with paint and varnish materials, which provides protection from corrosion. The design provides for a mosquito net. Mounted with screws or screws.

plastic grilles for ventilation and air conditioning systems

Designed to provide rational intake and exhaust ventilation in the room. Produced from high quality plastic. Evenly distributed air flow inside the room, have high resistance to mechanical damage and temperature changes. The design provides for the presence of spring-loaded lamellas, which can easily be removed for cleaning. Comfortable in installation and operation.

cone-shaped diffusers

Designed for installation in suspended ceiling systems. The design provides for the possibility of adjusting the diffusers in the direction of air flow. Mounted without the use of fasteners.

Methods for installing ventilation grids

In order to qualitatively establish a ventilation system, it is necessary to have professional knowledge and skills. Special materials and tools are used. Therefore, only professionals are required to install ventilation systems. With regard to the installation of ventilation gratings, anyone can do it with their own hands, since in this case it is only necessary to securely fix the grate to the surface with the help of fasteners or glue.

The design of almost any ventilation grille provides for a dismountable body, the rim of which is fixed directly to the air duct opening. Further on, the central part of the grill is installed on the rim, which can be easily removed for cleaning ventilation, and can also be easily installed into place.
  To prevent possible vibration, the rim of the ventilation grill is fixed to the rubber gasket. On the back side of the grid, you can install a fine mesh to protect from dust and small insects.

It would be superfluous to note that any ventilation grille is an obstacle to air penetration and is capable of creating aerodynamic resistance in the ventilation system. Therefore, the dimensions of the ventilation grids should be chosen in such a way that the efficiency of the ventilation system is not reduced.

installation of ventilation grilles with screws "in sweat"

The simplest and most affordable way of fixing the grill on a wooden, plastered, gypsum board or concrete surface. To accurately fix the grate, the holes on its rim are adjusted to the size of the screws of the screws. After mounting the head screws or screws are painted or decorated in a different way under the color of the grille.

mounting with glazing beads or plinth

Despite the fact that this method of fastening is very rare, it can be used to achieve a good result in rooms where there are decorative elements made of wood. The process of installation in this case is quite simple - the rim of the grate is pressed against the surface by a bead or skirting, which, in turn, is fastened by means of screws, screws or glue.

fixing the ventilation grille with bolts with a cone head "in sweat" to the hidden elements

In this case, the hidden corners or brackets are attached around the perimeter of the vent with a small indentation. After that, the ventilation grid is fixed through the holes previously fitted to the bolt dimensions.

fixing the ventilation grill on the adhesive

For such fastening liquid nails, polymeric glue "Titan", "Dragon", silicone, etc. are suitable. On the grid, the glue is applied using a mounting gun or manually along the entire perimeter, so that it protrudes slightly above the recess. Then it remains only to tightly attach the grate to the surface, and fix it with a mounting tape or paper tape that can be removed after a day.

Glue the grate to the surface very tightly, not allowing gaps, the surface before gluing can not be wet.
