Snip door blocks. Rules for installing interior doors in an apartment. The cost of installing doors and the procedure for installing doors
When installing the front door, the owners of apartments and houses are guided not only by their own preferences and understanding of comfort, but also by the code sanitary norms, ignoring which can lead to fines and forced alterations.
In accordance with the rules, the structure that overlaps entrance opening living quarters, is evacuation and is designed to ensure the unimpeded movement of people, also having sufficient dimensions to carry the wounded on a stretcher. Based on this, installing doors according to the rules fire safety accompanied by the following requirements:
Assembling the door frame
Most of the dog and cat doors offered in this section are designed to fit through the screen. It can be a window screen, a sliding screen door, or a screen in a screened porch. Another type is the "momentary" or hanging screen door, which can be installed in any doorway, be it an ordinary door, sliding door or French door.
There are two versions of the screen installation. With screen material on all 4 sides in the bottom corner where little drilling is required. Measure your pet upside down to determine how high the screen door should be. Using sharp blade, cut out the screen grid according to your marked lines.
- Lay down the screen door on the floor and mark your rough hole.
- Install your screen door.
The size of the light opening in multi-apartment residential buildings is at least 800x1900 mm.
In buildings or structures owned by organizations (with the exception of private residential buildings), it is prohibited to use additional doors or change the direction of their opening from the apartment to the corridor or to the landing, if this may interfere with the free movement of people living in this room or neighboring apartments.
How strong will a pet door be when installed through a screen?
When installing the pet door, it is recommended to use more heavy material for the screen, as weaker materials can certainly break out due to frequent use pet doors. Some pet doors for screens attach to the corner of the screen so that two sides can be attached to the frame and the other two sides are attached to the screen material. These kinds of pet doors are much stronger than the options that have all four sides attached to the screen material and can tolerate much more use as well as animals. bigger size.
The regulatory literature also contains a number of rules regarding such indicators as the airtightness of the entrance structure, its heat and sound insulation characteristics, as well as special requirements, extending to fire-resistant, bullet-resistant and other special-purpose canvases.
In the section "Construction heat engineering" blowability (the ability to pass moving air masses) outer door SNiP defines a value not exceeding 1.5 kg / m2 hour. To ensure this indicator, the blocks must be equipped with seals in the area of the porches and folds.
How easy is it to install pet doors on screens?
For pet doors that are installed with screen material on all four sides, only a few simple tools for installation, while those that attach to the corner of the screen require minor drilling. Home screen doors are easier to install than door or wall doors, but your ability to install them still depends on the tools and skills you have.
If you want to keep your pet's door on your screen going as well as constantly getting closer to the bugs, investing in Hale is a smart idea. Because it protects the frame itself, it will be able to carry active and large pets without screen tearing. The pet door is made of durable aluminum frame which does not break down even with years of use.
In order to comply with the recommendations of SNiP, the doors must be installed in such a way that the movable part of the structure fits snugly against the frame. The gaps between the box and the wall must be carefully sealed. The tightness of the product is provided by sealing layers of rubberized fabric or rubber.
As prescribed in the chapter "Residential buildings" SNiP, entrance doors apartment buildings should separate premises for any purpose and floor corridors from landings and elevator lobbies. In residential buildings, the corridors between the stairs are recommended to be separated by partitions with doors equipped with door closers.
Will the pet door contain bugs?
Some flaps are better than others. dampers with large quantity magnets will close more quickly and consistently like Hale's, while other options may take longer to swing to the closed position and be less wind resistant.
There are several pet doors on the market that install directly through the screen and rely on the screen for support on all four sides. They are different sizes and are most suitable for small and less active pets such as cats, although some may be sized for larger dogs.
In the "Protection from noise" section, the noise insulation indicators of structures installed at the entrances to residential and public buildings. In accordance with SNiP, metal doors, which are used in lobbies, lobbies, corridors and on stairwells, must have an isolation index of 30 dB.
The requirements that fire doors must meet are proposed by SNiP for consideration in the chapter “Fire Safety of Buildings and Structures”, as well as a number of other sections relating to fire resistance test methods. Safes and vaults of valuables, banking, burglary and bulletproof structures are separately standardized.
For larger or more active pets, we recommend something more durable. Choose a brand that allows you to mount the pet door frame to the screen frame with screws from sheet metal on one side and across the bottom. The screen is then reconnected with a special groove on both sides.
Important note regarding snap style: We've received some complaints from people with heavy screening on wires they can't install because the screen is too stiff to fit into the groove provided by the pet door. If you have this type of screening, we offer you "strong mounts". In addition, we are worried about very, very light fiberglass screening. It may not be strong enough to support latch types even with gentle use.
All structures on the escape route, in particular those installed at the exits, must open outwards. If the project provides for inward-opening entrance doors, fire safety allows their installation in the following cases:
When fully opened, an unoccupied space of at least 1 m remains between the canvas and the wall.
Q: What are the advantages and disadvantages of installing a screen pet door?
In particular, clamp styles are very inexpensive and easy to install or remove. All you will need to replace is the screen if you decide to no longer have a pet door. If you have nowhere else to put your pet door, then it's good to know that you can use the pet door through a window, door or porch screen. The door through the screen allows you to still use the screen for ventilation in spring and summer without making mistakes. This may not matter for an indoor covered window, but it may be highly undesirable for home living in colder climates. If you lock the pet, you will find the pet scratching the screen in desperation while trying to use the pet door. With a clamp style pet door, it's not as good as a frame mount style. However, an active dog can take the pet door out into the backyard as it passes, although the pet door may be large enough for the dog as the door is not as secure only with screen support. screen doors are large, economical options for pet owners, but you just need to be sure the door you buy is right for your pet! And as with anything, you usually "pay for what you get" as far as durability.
Does screen thickness matter?
- Obviously you've let the weather go with your pet.
- With a calmer pet, everything should be fine.
The open sash does not block access to neighboring rooms or apartments.
The design does not block the opening of adjacent doors.
The width of the opening is at least 800 mm.
Opening doors for fire safety is not standardized for the following rooms:
Multi-apartment, single-apartment, blocked residential buildings;
Q: Will the screen in the pet doors match the screen?
The wide range of flap sizes makes it easy for your dog or cat to be comfortable. However, if you have a lightweight fiberglass screen, then the clip type may not have enough support and installing a pet door may cause the material to break. With the heavier type of screen, one problem with the clamp style is that they use pins that go through the screen and into the frame on the other side.
Q: What if my screen has already been torn out by my pet?
We have found that in situations where the screen material is heavier, that pre-starting the holes in the screen ensures that the pins go all the way, which helps hold both sides of the frame together. You will need to replace the damaged screen and then install the pet door. If you're planning on getting a dog door that attaches to the screen itself, then as long as the pet frame is larger than the torn part, you'll likely be able to do the installation from the screen, as is.
Premises in which no more than 15 people stay at the same time;
Storerooms, which do not provide for permanent jobs, with an area of \u200b\u200bno more than 200 square meters;
Access to the platform stairs of the 3rd type (open external stairs);
Bathrooms;
Outdoor structures installed at the entrances to buildings in the northern climatic zone.
This, of course, implies that you have the skill of re-splicing the screen into a pet door - a job that is not particularly easy. You may need to make a trip to the screen store to make sure you good result. This bar helps to secure the screen mounting angle in the middle of the door as it is the furthest away from the framing.
Q: Do I need to cut the screen?
The reason most of them don't is because if you need to block a pet door, you simply close the door or window.
Q: Do I need to buy a new screen
Q: Do I need to screw it to the frame. The rest go directly through the screen material. If you choose a screen dog or cat door that is completely set in the screen material, then it will be the same as everything else using these instructions. This means you may need a higher door lock for pets than usual.Fire safety requirements for doors also regulate the width of the escape route for products opening from the apartment into the corridor: this indicator is calculated by reducing the width of the corridor by half door leaf(if the openings are located on one side of the corridor) or the width of the whole canvas (with two-sided openings). At the same time, as fire safety says, the doors located in the floor corridors of apartment buildings, this requirement do not obey.
The top of the flap should be at least 1 inch above the highest point of your pet's back, and the width should be wide enough so that their sides don't get caught in the pet door frame. An animal door that is installed with screen materials on all sides is relatively easy to install and the only tool you will likely need is a knife. Home screen doors that fit into a screen frame are more complex and may require additional tools.
Preparing the walls of the opening before installing the doors
Pet curtains are usually easier to install than through doors or walls, but you can still ask a professional to get the job done right. The front door is the interface between indoor and outdoor, private and public space. At the time of buying new door you should pay attention to things like safety and thermal insulation in addition to design.
Changing the opening side is not a redevelopment, if this does not transfer the structure or create a new opening. In this case, references to the original project of the house with the direction of movement of the canvas embedded in it do not work - each owner has the right to decide independently what type of opening he needs.
Which hinges to choose
The most important tasks of the front door are: protection against colds, security and making the house attractive. If you're looking to buy a new front door, you'll find a huge range in all styles, materials, and price ranges, from a simple, inexpensive plastic model to historical looking ones. wooden doors to modern design door aluminum and glass. However, the decisive purchase criteria should be the "intrinsic value" of the door, which provides security and thermal insulation.
Thus, if we are talking about residential premises, the installation of fire safety doors with a change in the direction of opening can be carried out without additional approvals. However, it should be borne in mind that the open sash should in no way block the entrance opening of the neighbors.
To ensure that entrance and interior doors meet the requirements of safety, fire resistance and other necessary conditions comfortable living, their installation must be carried out in accordance with normative documents. Failure to comply with the installation rules can lead to additional material costs, inconvenience, danger, and even litigation. Therefore, before deviating from the standards for any reason, you should think about possible consequences. The use of the recommendations of one or another collection of SNiP in the process of work depends on the material of manufacture, the location and purpose of the door structure.
What distinguishes a "real" front door?
Quality Criteria entrance doors include stability, durability, weather resistance, thermal insulation and burglary resistance. High quality doors can be made from all common materials or combinations of materials.
Safety as an important purchase criterion
Burglary-resistant doors are divided into six resistance classes. In order for a front door to actually meet the requirements of a test standard, it must also be certified, for example by the German Standards Institute or the Property Insurers' Association. In addition, it must be installed in accordance with the instructions of the door manufacturer - preferably by a specialist.
What are the rules for?
The first SNiP appeared in the USSR in the 50s of the last century. Over the years, the standards have been improved and changed, but the fundamental principles used in the installation of doors have remained intact and, importantly, have stood the test of time. In the post-Soviet space, in most cases, they try to adhere to the requirements of SNiP, although today they are trying to replace them with SP and TU, which is not always true.Along with the fact that the entrance doors save from the cold, drafts and uninvited guests, they also, according to the norms of SNiP, serve as evacuation passages that provide in case of emergency unhindered movement of an increased flow of people, carrying the wounded and sick. In addition, their function is to provide free space to move undisassembled furniture sets and large household appliances.
Door sizes are regulated state standards and correspond to the dimensions of the wall openings laid down by the designers in the construction documentation. Blocks, in this case, do not have to be ordered individually, which is convenient and rational. In exceptional cases, in order not to violate the architectural appearance of the building or at the special request of the owner of the mansion, it is allowed to install door blocks custom sizes. But deviations are allowed only upwards, in order to avoid creating dangerous situations.
It should be noted that interior doors can be made a little narrower and lower than the outer ones.
It is also necessary to rely on the rules of SNiP due to the fact that they quite clearly indicate the long-developed and justified:
- methods of heat and sound insulation of entrance and interior doors;
- fire resistance and bullet resistance characteristics of special door blocks;
- air tightness standards for external enclosing structures;
- methods that guarantee maximum burglary resistance, etc.
Today it is necessary to experiment in rare cases, since the prescribed norms provide an opportunity quality installation any door. The main thing that is required from private developers and reputable construction companies- this is strict adherence to SNiP, although some experts argue that their implementation is not at all necessary.
It should be understood that the current regulations are not aimed at complicating the process of installing doors, but at ensuring comfort and safety, the absence of noise and cold inside the house.
Some requirements of SNiP
It is worth noting that it will not be possible to tell about all the standards required for the installation of a particular door in one article. The problem is not even in the number of rules, but in the variety of materials, models and places for installing doors. But highlight General requirements relating to most entrance or interior building envelopes, it is still possible.
According to SNiP, tolerance established door frame vertically can be no more than 3mm. The side frame posts are attached to the slopes at least at two points on each side. Moreover, the distance between them in the same plane should be no more than 100 cm.
When installing a new door, adhere to simple rule, which consists in the fact that its sash in the open position should not overlap adjacent openings inside the apartment or on landing. In extreme cases, you will need to change the side of the opening of the canvas.
For door blocks, their correct geometry and the absence of visual defects are important. But no less significant point is the tightness of the closing of the doors of the entrance doors and the absence of gaps. The normative air permeability of the external enclosing structures is 1.5 kg / (m2 per hour), therefore special meaning here it is given to the sealing contours installed in the porches between the box and the canvas. They also prevent the penetration of dust and odors from the street, as well as the appearance of drafts. But when installing internal doors the gaps between the floor and the doors can be 5mm for rooms and 12mm for bathrooms.
The noise insulation standards for entrance doors allow the penetration of sound waves into the apartment at a level of no more than 30 dB, which is stipulated in the relevant SNiP. The calculation of the thermal insulation of the door is carried out according to several indicators, including data on the average winter temperature of a particular region.
Control of the installation of door blocks
On the preparatory stage the presence of a passport for the product with a record of the provision of a guarantee is checked. The surface of the door is also inspected and, with the help of a tape measure, the compliance of the structure with the declared geometric dimensions is determined. Before starting the installation, check:
- dimensions of the wall opening;
- the accuracy of the applied markup;
- the correct location of embedded elements required for fasteners.
Door installation is accompanied technical inspection and preparation of certificates of examination hidden works. The following are subject to special scrutiny:
- tightness of insulation of gaps between wall slopes and the box;
- the quality of fastening of the door frame and sealing gaskets;
- compliance of the mounted block with the design position;
- correct installation of hardware and accessories;
- sash fit density.
Operational control, according to the standards, is performed by the master or foreman of the company responsible for installing the door, and acceptance is performed by the customer's representative or the owner of the premises.
