In order for the doors to ensure the comfort and safety of the residents of the apartment, when installing them, it is necessary to rely on regulatory documents, such as SNiP (building codes and rules) and GOST (state standard). The SNiP spelled out the requirements and recommendations for the installation of interior doors, GOST defines their dimensions, technical characteristics and features of the device.
Requirements for the manufacture of doors according to GOST
Despite the wide variety of design solutions, the production of doors for rooms should not contradict the clear conditions dictated by state standards. There is a whole list of regulatory documents that define the rules for the manufacture of this type of product.
- GOST 6629-88 contains an exhaustive list of all specifications and standards that relate to doors made of wood.
- GOST 475–78 establishes general requirements for all types of wooden products.
- GOST 24698–81 defines types, sizes and design options for interior doors.
- GOST 30970–2002 describes the characteristics of PVC products.
- Certificate of Conformity No. 6629-88 provides connection options and standard sizes.
- Standard STB 2433-2015 “Door blocks. General technical conditions” includes classification, parameters of different types of doors, requirements for them.
- GOST 538–88 provides information on the requirements for door extensions, hinges and fasteners.
Characteristics of doors according to GOST
Gosstandart sets the following parameters for these products:
- the height of the product and the door unit - nominal values;
- the width of the box and canvas;
- product safety in terms of its environmental friendliness;
- possible ways to decorate the structure;
- materials that can be used for the manufacture of fittings -door hinges, overlays and pens.
Door structures according to GOST must comply with the dimensions indicated in the table.
Requirements for the material, design and installation of doors
Full information on the production regulations can be obtained from the relevant documents. We list only some of the requirements related to the installation of doors for rooms.
- When it comes to wood products, the state standard gives clear recommendations regarding the raw materials. The moisture content of the wood used in the manufacture of door structures should not exceed 8%, in addition, the permissible fluctuations in humidity for wood of different species are indicated.
- The wooden surface should not have knots and other defects. Separately, the condition of the places where the fittings will be attached is stipulated: there should be no hidden defects, such as wormholes or resin cavities, which affect the quality of the attachment.
- Installation of interior doors involves maintaining a technological gap, which can be equal to 10-15 millimeters. This installation gap is subsequently filled with foam and closed with a door trim.
- Internal doors must be equipped box, which exceeds the size of the sash by 3 millimeters on all sides except for the bottom. The lower gap between the product and the threshold or floor must be at least 10 millimeters.
- Locking mechanisms have different types and methods of fastening, which depend on the mode of operation, the weight of the structure, and the size of the opening parts. The location and number of loops also depend on these conditions.
- For plastic structures, only special mounting loops and door extensions should be used.
Basic requirements of SNiP for the installation of interior doors
The use of SNiP standards allows for high-quality installation of any door structure, thanks to which it will be convenient and safe to use.Let's consider the most essential requirements.
The deviation of the door frame of the installed door vertically should not exceed 3 millimeters.
- Fastening of the side frame racks must be carried out at least at two points on both sides, the distance between them can vary within 100 centimeters.
- The door should open towards the larger room. If the door structure is installed between the room and the corridor, then it will open towards the room.
- The new door must be installed in such a way that, when opened, it does not block other doorways.
- If the floors in adjacent rooms have different coverage, then, if necessary, a threshold can be set. Floors of the same type do not require its installation.
Control of the installation of door blocks
According to the rules of SNiP, all steps for fastening an internal door are controlled accordingly.
Preparatory stage
Includes verification of the presence of a passport for the product, which must contain a record of the guarantee. At this stage, it is necessary to inspect the surface of the structure for defects, measure the product to find out if it meets the declared parameters. Before proceeding with the installation, it is necessary to check:
- opening dimensions;
- markup accuracy;
- the correct location of the elements that are designed to fasten parts.
Installation phase
During installation, a technical inspection is carried out, and certificates of examination of hidden works are drawn up. Must be checked:
- gaps between the slopes of the walls and the box for the tightness of the insulation;
- quality of fastening of the frame, as well as sealing gaskets;
- compliance of the finished block with the design position;
- sash fitting;
- correct insertion of fittings.
Control stage
If installation services were provided by a construction company, according to the standards, the verification is carried out by a foreman or foreman of the company. The quality of installation is assessed by the representative of the customer or the owner of the apartment.
