Overhaul is a time-consuming task, during which many nuances must be taken into account. Especially if you plan to approach it thoroughly and want to replace the doors separating separate rooms. As practice shows, it is with them that the biggest problems arise. What is it connected with? According to the requirements of SNiP, the width of the doorway of the interior door must correspond to certain dimensions. At the same time, many do not take into account the errors that arise due to the unevenness of the walls, and the mistakes made by the builders during the construction of the object. Let's understand the basic GOST recommendations and find out how to do it right.
General information
When determining the dimensions of the opening, it is very important to take into account its functional affiliation and design features. For example, the width of the doorway of an interior door leading to a bathroom or toilet may be slightly smaller than to a living room or bedroom. At the same time, GOST6629-88 highlights two key parameters:
- width;
- height.
As for the depth, it is not of fundamental importance and depends on the materials used to build the partitions. Let's take a closer look at this and find out what each of them is.
Height
When repairing, the width of the doorway of an interior door is calculated taking into account many parameters. The main one is the height. As a rule, in modern houses it is 190-200 centimeters in the case of a bathroom and 10-20 cm more for other rooms. This height is quite enough for the comfortable movement of an average person with a height of 1.7-1.8 meters. However, there are also openings exceeding two meters. Most often they are made in apartments and houses with very high ceilings. But this is already a deviation from generally accepted standards, so we will not dwell on such things.
Width
So we come to the parameter of interest to many people. The standard, according to SNiP, the width of the doorway of the interior door is 60 centimeters when installing conventional single-leaf structures. This figure was calculated by experts, taking into account the size of an adult with average physical data. For the toilet and bathroom, the width can be reduced by 5 centimeters, and for the living room, on the contrary, increased to 1.2 meters.
Custom sizes
In some modern apartments and private houses, the width of the doorway of the interior door is 80 cm. What to do in this case? This is considered a departure from the standards, which many go for with the aim of increasing functionality and practicality, as well as creating a unique interior design.
Depending on the redevelopment project, doorways can expand up to 1.6 meters with the subsequent installation of a double-floor structure. This width allows you to move even large-sized furniture around the apartment without any problems. In addition, it visually expands the room, making it more spacious and bright. But there are times when, on the contrary, work is required to reduce the width of the opening. Such work is permissible provided that the basic rules and requirements of evacuation and fire safety are observed. In accordance with SNiP 21-01-97, entrance doors are an exit to evacuation. In the event of an incident, such as a fire or natural disaster, people must be able to leave the premises freely and quickly.
Door arches
As we have already found out, when installing conventional structures, the standard width of the doorway of the interior door is 60 centimeters. But what about the arches, because they belong to a separate group because of their design features? Their dimensions can expand significantly if the redevelopment does not affect the load-bearing walls. However, here it is necessary to take into account the type of construction.
Arches can be as follows:
- classic;
- rectangular;
- asymmetric;
- ellipsoid;
- round;
- eastern;
- semi-arch.
The dimensions of rectangular arches are no different from those of ordinary interior doors. For classical and oriental designs, 80 centimeters are usually assigned. The smaller dimensions are due to the more complex design of the upper rounding. The rest of the options for interior arched openings are on average 90-100 centimeters wide. Nobody makes arches of standard width, because they will look very ridiculous, which will negatively affect the entire interior.
Features of calculating the optimal size
Let's take a closer look at this aspect. If you plan to change the doors in your home, it is very important to determine the size of the openings. Thanks to this, you can not only avoid many problems, but also greatly simplify the subsequent installation of structures. So, for example, if the width of the doorway of the interior door is incorrectly calculated, the layout will have to be redone, which is associated with additional physical and financial costs.
You need to be especially careful when carrying out repairs in new buildings. New buildings shrink over time that most people don't take into account. Specific terms depend on the building materials used. The worst situation is with wooden and log buildings, the height of which can decrease from 2 to 15 in a few years.centimeters. Also, the size of the opening depends on the type of structures. When installing sliding and roto doors, you must additionally take a margin of 10 centimeters. It is necessary to accommodate complex opening and closing mechanisms.
The last criterion that affects the size of the opening is the interior decoration of the room. If ordinary linoleum without insulation is used as a floor covering, then it will take 1 centimeter of height, and laminate - two at all. Under warm floors you need to take up to 10 centimeters. It all depends on the heating elements used.
A few words about types of structures
What do you need to know about this? When calculating the width of the doorway of an interior door, you need to decide in advance which structures you will install. They are divided into many types depending on the totality of certain parameters. By the number of canvases, the doors are divided:
- to single-field;
- two-pole;
- one and a half.
According to the type of installation, the structures are:
- single and double swing;
- folding;
- sliding open and pencil cases;
- swinging.
By material, interior doors can be:
- wooden;
- glass;
- combined;
- metal;
- metal-plastic.
All these parameters affect the dimensions of doorways, so experts recommend determining in advance whichIt is the structures that you will install in your home. So you will save not only your own time and money, but also nerves.
General tips and tricks
What else do you need to know about the height and width of the doorway of an interior door in a panel house? When taking measurements, you need to add 3 centimeters, which will be spent on adjusting the structure with wedges and mounting foam when installing the box. But it is important to understand that this value may differ if the dimensions of the opening do not meet the established building standards. In addition, to increase the thermal insulation of the premises and reduce heat losses in the openings, it may be necessary to install a threshold. It also requires some headroom.
When installing the door frame, you need to start from the finished surface. Otherwise, after installation, the structure may rub against the floor. It is impossible to eliminate this defect on your own, without experience and special tools. And not all types of doors provide for this. For example, in the case of metal-plastic and metal sheets, it is only possible to adjust the angle of inclination and the density of fit to the cut. However, this is a very time-consuming task that requires high precision, so without the help of qualified specialists, you are unlikely to be able to cope.
Conclusion
So, now you know what the width of the doorway of the interior door should be, how to calculate it correctly and what to pay attention to. It is very important to correctly determine the dimensions, because they affectnot only on the functionality of structures, but also on the aesthetics of the interior. Even a small mistake made or an unaccounted millimeter as a result can turn into big problems. Therefore, if you have never done anything like this before or are afraid that you will not be able to handle it yourself, then it is better to seek help from experienced craftsmen who will do everything qualitatively in accordance with all the norms and requirements of SNiP.
