The lack of fresh air in the house can cause the residents to feel unwell, because carbon dioxide accumulates in a room that is not ventilated for a long time, and a sufficient amount of oxygen is required for a person to feel normal. In addition, household chemicals and finishing materials release toxins into the air, which, when accumulated, can also be harmful to health.
If we talk about ventilation in the bathroom, then the situation is even more serious. In the absence of air movement in a humid environment, molds form, the surface of walls, doors, furniture accumulate moisture and become unusable.
The problem of ventilation of bathrooms over the past few years has become especially urgent in connection with the appearance on the market of new noise-, hydro- and thermal insulation materials. Finishing with such materials makes the bathroom more comfortable and beautiful, but many of them do not allow fresh air into the room. When installing a fan in the bathroom, effective ventilation of the room will only occur when the door is open, because a good draft requires a draft. According to the rules, there should be a small gap between the bottom of the door and the floor, but most people find this approach uncomfortable and unaesthetic and install doors that close very tightly without leaving gaps.
All these problems can be solved by the ventilation grille mounted on the door. Today on sale you can find doors with an already integrated grille or with special ventilation holes-rings. But if the door is already installed and there is a problem with air circulation, then you just need to purchase and install the grille.
Types of ventilation grills
Today in the market for construction products you can find many different variations of ventilation grilles. All these designs have differences in shape, purpose, design and color materials, sizes, price.
The primary classification feature that defines the types of gratings is the method and place of their installation. On this basis, they are divided into:
- inflow;
- domestic;
- outdoor.
Supply air grilles are used for installation on the door. They are made from the following materials:
- aluminum;
- plastic;
- wood;
- steel and others.
Plastic ventilation grilles have high corrosion resistance and reasonable price. But when exposed to direct sunlight, the plastic loses its attractive appearance, and over time can begin to collapse. Therefore, plastic grilles are best used for interior doors inside the house.
Aluminum grilles are quite durable, lightweight, not afraid of sunlight, but are somewhat more expensive than plastic ones.
Wooden grilles are designed for indoor installation. Their advantages: environmental safety, external presentability, allowing you to harmoniously fit into the interior of the room. However, it should be borne in mind that natural wood requires special regular care, in the absence of which the product may lose its appearance and deteriorate. The cost of wooden ventilation grills in comparison with other analogues is high.
Steel gratings are heavy and have a high cost, but at the same time are considered the most durable and durable. Such structures are most often installed on the front doors, since they are too heavy for interior doors.
When installing the grille on the front door, it is necessary to choose a model with a protective mosquito net so that mosquitoes and flies do not penetrate the house.
Ventilation grilles allow very little light to pass through and virtually eliminate the likelihood of a view; it is impossible to see a person outside the door through such a structure. In shape, these products can be round, square or rectangular, but the latter option is the most common.
Design features
The main part of the structure is equipped with V-shaped lamellas fixed on a frame made of plastic or metal, and the reciprocal part is already without lamellas. Despite the fact that this design is quite simple, such products effectively fulfill their function, maintaining an optimal microclimate in the rooms. Mounting the grill will prevent mold, mildew and high humidity.
Rectangular door grilles
Rectangular grilles are installed on the kitchen doors, in the bathroom and toilet. This allows airflow to circulate correctly inside rooms. In addition, such products are also used for mounting in window sills so that warm air masses emanating from heating radiators are evenly distributed throughout the room.
These structures are made of high quality and durable plastic. Some models are equipped with insect screens or a movable flap that controls air flow. Also, if desired, you can install a grill with a built-in fan - in this case, the ventilation effect will be best. Today, there are various color and design options available for sale, so for each door you can choose a grille that is suitable in color and style.
Round grilles
The design of round gratings is practically no different from rectangular. Such products are also equipped with mosquito nets, may have movable dampers or a built-in fan. The size of round structures, as a rule, does not exceed 15-20 cm in diameter, and for their installation in the door round holes are made in size. Products up to 10 cm in diameter are installed on the bottom of the door several pieces in a row. Larger grilles can be placed on the sides of the bottom or top of the door. In the presence of moisture and mold inside furniture cabinets, such grilles are installed on the cabinet doors. In this case, glue and mounting ribs are used for installation.
Installation
If there is no proper air circulation in the office production room, as well as in the private bathroom, in the kitchen or in the bathroom, ventilation grilles must be installed on the door. You can do this yourself or seek help from specialists who will perform the following steps:
- According to building codes, the optimum size of the grill required for your door will be determined. The size depends on the internal dimensions of the room and its purpose.
- Make a hole in the door of the right size and install the grill.
For self-installation, you will need such tools:
- Ruler and pencil;
- jigsaw;
- screwdriver or glue.
Work execution order:
- First, with the help of a ruler, you need to take the dimensions of the purchased gratings (in the kit, as a rule, there are always two of them).
- Next, on the door, you need to mark the places where the grilles will be located. In this case, the holes should be greater than the length and width of approximately 1-2 mm.
- Then, at the corners of the marking, four round holes are made with a large drill.
- After inserting the jigsaw blade into one of the holes, carefully cut a rectangle of the appropriate size according to the marking. It is necessary to cut carefully so that the material does not break off. Most room doors are filled inside with paper honeycombs. Please note that the jigsaw is suitable for doors made of wood or wood processing materials.For other materials, appropriate tools are used.
- Now attach the grilles to the two sides of the hole. If they enter too tightly, increase the hole by grinding it with a file or a rasp.
- If the instructions for use of the product indicate that the grill is attached to the glue, then they will be attached using construction glue. Before applying glue to the door surface, it must be treated with a cleaning agent to remove dirt and grease. Otherwise, the grill may peel off after some time. Most models designed for doors are fixed with screws.
Ventilation grilles not only restore proper air circulation in the rooms, but also perform a decorative function. These designs have a fairly attractive appearance, giving the dwelling modernity.
