Ventilation

The presence of a ventilation system in the room often indicate ventilation grilles. One should not think that they are needed only as a decorative element of the structure; there is also a great practical benefit from them. Today we will talk about metal models - about their types, devices and methods of fastening. You will learn a lot of interesting things if you read the article to the end.

Metal grilles for ventilation of various shapes and purposes

The role and importance of ventilation grids

The main purpose of the element is to ensure unhindered air exchange in the room, thanks to the correct distribution of the air flow and the supply of oxygen in the required quantity. They are mandatory for each building and structure, because it is thanks to them that at the time of the outbreak of fires it is possible to eliminate smoke and significantly reduce the possibility of CO poisoning.

Tip: the installation of ventilation grills should be made in accordance with fire safety regulations.

Kinds

Today, the construction market offers consumers metal exterior ventilation grilles and interior, the designs of which differ:

  • by material;
  • by forms;
  • by size;
  • by color;
  • by design;
  • worth.

Classification

Specialists classify these elements according to four main and several minor features.

Consider them in more detail:

  1. Method and place of their installation. In this case, they can be divided into those that are used:
Outside the building
  • According to the name they should be installed outside the structure.
  • Designed to protect air duct openings from precipitation, debris, small rodents and insects.
  • Most often they are made of high-strength aluminum, resistant to UV rays and negative environmental effects.
  • They must have blinds fixed at the required angle.
  • They are equipped with a heating function to prevent frost formation during the cold season.
Indoors
  1. Installation is carried out inside the building.
  2. Instruction allows their manufacture from durable plastic, as they do not experience large loads during operation.
  3. Differ in visual appeal, small size, different style decisions, colors. All this makes it possible to optimally choose a model for the overall interior of the room.
  4. Installation does not require a lot of effort and certain skills, therefore, set their own hands. Operation is easy.
  5. Often can be equipped with removable central part or adjustable blinds. The latter make it possible to easily change the direction of the air flow and its intensity.

There are also overflow options that are used for mounting in doors, walls and partitions. They carry a direct functional load, simultaneously interconnecting adjacent rooms, ensuring their normal air exchange and creating light and sound insulation. The grilles are equipped with V-shaped blinds and are arranged so as to overlap one another. (See also the article Roof ventilation: features.)

  1. Design features:
    • unregulated - not equipped with blinds, so you can not control the flow of air into the room;
    • adjustable - have movable louvers with which you can change the duct cross-section at any time and adjust the air flow;
    • inertial - can automatically block the ventilation immediately after the termination of air movement in the system.
    1. Materials:
      • plastic;
      • Aluminum grates for ventilation of low weight and relatively high strength. May maintain the original properties for a long time under the action of sunlight. Their price is higher than plastic counterparts;
      Reliable stainless steel ventilation grilles with fixed louvers
        • tree;
        • Steel - metal ventilation grilles according to GOST have a large weight and higher strength than aluminum.
        1. The form most often happens:
          • round;
          • rectangular;
          • oval.

          Mounting methods

          Ventilation grills of industrial designs made of metal or according to individual sketches make it possible to create a decorative effect in any interior, in the latter case a unique one. In order for the product to receive technological completeness, accelerate and simplify installation, you should take care of the fastening system for it.

          Below we offer you various options that are divided into two groups. The first is technically simple fixing methods that do not affect the final cost of the product. The second are examples where you need to perform preliminary plumbing work, for example, to make corners, drill, use welding, stripping.

          Tip: if you carry out a metal grill to order, you must agree in advance all the nuances of installation work, which will depend on the weight, dimensions and its operation.

          First group
          1. Fastening with screws in the floor of the grill is considered the most affordable and simple option. The process can be carried out on a wooden surface, plastered wall, plasterboard or concrete. The holes on the grille for a neat installation are countersinked according to the diameter of the screw cap, which is best painted in the color of the grille.
          2. Installation with the help of profile glazing beads or skirting boards is used quite rarely, although it makes it possible to get the desired result in interiors where wooden framing is used and there are wooden hulls for radiators.
          Second group It is a more complex structure:
          1. Mounting in sweat with cone-head bolts to hidden elements. On the perimeter of the lattice with a given indent from the edge it is necessary to fix the hidden brackets or corners. Then a hole is drilled along the diameter of the bolt, which coincides with the threaded holes on the brackets, the product is fixed in place. Can be mounted in the plane of the ceiling or wall, and indented.
          2. Use spacers or glue. The latter method is convenient when installing gratings on liquid nails or glue. Spacer clamps make it possible to dismantle the product later, providing quick and convenient installation.
          3. The option with a tight seat in the hole on the expansion clamps or glue differs hidden fasteners. From the seamy side, pre-guide elements are welded to the grid. Installation is carried out on liquid nails or glue, as well as using spacer clamps.
          4. Through the holes in the pattern. Pre-welded to the lattice brackets, which have already drilled site under the screw. The method is easy to install, besides there is the possibility of dismantling the product. Difficulty will be only in the exact positioning of wooden platforms.
          5. Mounting products with blind guides using spacers is a standard fixture for industrial ventilation grilles. The use of spacer spring elements allows you to quickly and easily put the element on the finished hole.
