Ventilation grilles for doors to the bathroom, room, room

The lack of fresh air in the house can cause the tenants to feel unwell, since 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's normal well-being. In addition, household chemicals and finishing materials release toxins into the air, which, accumulating, 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 are formed, the surfaces of walls, doors, furniture accumulate moisture and become unusable.

The problem of ventilation in bathrooms has become especially relevant over the past few years 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 let fresh air into the room. When installing a fan in a bathroom, effective ventilation of the room will occur only when the door is open, since a draft is needed for the fan to work well. 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 inconvenient and unaesthetic and install doors that close very tightly, leaving no gaps.

All these problems can be solved by a ventilation grill installed on the door. Today on sale you can find doors with an already built-in 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 grill.

Types of ventilation grilles

Today, on 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, prices.

The primary classification feature that determines the types of grilles is the method and place of their installation. On this basis, they are divided into:

• supply air;
• internal;
• outdoor.

For installation on the door, supply grilles are used. They are made from the following materials:

• aluminum;
• plastic;
• wood;
• steel and others.

Ventilation grilles made of plastic have high corrosion resistance and reasonable price. But when direct sunlight hits them, the plastic loses its attractive appearance, and over time it can begin to deteriorate. Therefore, plastic grilles are best used for interior doors inside the house.

Aluminum gratings are quite durable, lightweight, are not afraid of sunlight, but they are somewhat more expensive than plastic ones.

Wooden grilles are designed for indoor installation. Their advantages: environmental safety, external presentability, which allows you to harmoniously fit into the interior of the room. However, it should be borne in mind that natural wood requires special regular maintenance, in the absence of which the product may lose its appearance and deteriorate. The cost of wooden ventilation grilles is high in comparison with other analogues.

Steel gratings are heavy and expensive, but at the same time are considered the most durable and durable.Such structures are most often installed on front doors, since they are too heavy for interior doors.

When installing a grill on the front door, you must choose a model with a protective mosquito net so that mosquitoes and flies do not enter the house.

Ventilation grilles let in very little light and practically exclude the possibility of viewing; it is impossible to see the person behind 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 counterpart is already without lamellae. Despite the fact that this design is quite simple, such products effectively perform their function, maintaining an optimal microclimate in the rooms. Installation of the grille will prevent the appearance of mold, mildew and high humidity.

Rectangular door grilles

Rectangular grilles are installed on kitchen doors, bathrooms and toilets. This allows the air flow to circulate properly inside the rooms. In addition, such products are also used for installation 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 airflow damper. Also, if desired, you can install a grill with a built-in fan - in this case, the ventilation effect will be the best. Today, there are various color and design options on sale, so for each door you can choose a grille that matches the color and style.

Round grates

The design of round grilles is practically no different from rectangular ones. Such products are also equipped with a mosquito net, can 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, round holes are made in the door in size. Products up to 10 cm in diameter are installed at 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 a private bathroom, kitchen or bathroom, ventilation grilles must be installed on the door. You can do this yourself or ask for help from specialists who will perform the following steps:

1. The building code will determine the optimal size of the grille required for your door. The size depends on the internal dimensions of the room and its purpose.
2. They will make a hole in the door of the required size and install the grill.

For self-installation, you will need the following tools:

• Ruler and pencil;
• jigsaw;
• screwdriver or glue.

Work order:

1. First, using a ruler, you need to take off the dimensions of the purchased grilles (there are usually two of them in the kit).
2. Next, on the door, you need to mark the places where the grilles will be located. In this case, the holes should be approximately 1-2 mm larger than the length and width.
3. Then four round holes are made at the corners of the marking with a large drill.
4. Insert the jigsaw blade into one of the holes and carefully cut out a rectangle of the appropriate size along the markings. You need to cut carefully so that the material does not break off. Most room doors are filled with paper honeycomb inside.It should be borne in mind that the jigsaw is suitable for doors made of wood or wood processing materials. For other materials, appropriate tools are used.
5. Now attach the grates to the two sides of the hole made. If they enter too tightly, then enlarge the hole by sharpening with a file or a rasp.
6. If the instructions for use of the product indicate that the grille is attached with glue, then they will be attached using construction glue. Before applying glue to the surface of the door, it must be treated with a cleaning agent to remove dirt and grease. Otherwise, the grill may come off after a while. Most models for doors are fixed with self-tapping screws.

Ventilation grilles not only restore the correct air circulation in the premises, but also perform a decorative function. These structures are quite attractive, giving the home a modern touch.
