Where is the best place to put shtulpovye structures

A double—leaf metal-plastic window, in which both sashes open, is arranged according to a standard scheme: both sashes in the closed position are fixed on an impost - a vertical partition. This is not always convenient — the partition divides the opening in half and can interfere with the view.

Therefore, windows and doors with a shtulpovy opening system are used as an alternative. This system is not new: this was how double-leaf wooden windows were opened, in which the sashes were overlapping in the closed position. The shtulpovogo opening scheme is borrowed from such structures — and is successfully used in the manufacture of PVC products.

Shtulpovy principle of opening

There is a main difference in a shtulpovy window or door — the two opening shutters are adjacent to each other, and not to the impost:

• For reliable docking, one of the flaps is equipped with a special profile — a stulp (it is also called a false impost). The shtulp is attached to the sash itself and covers the gap when closing the window.
• Since there is no impost on which the response bars can be installed, the structure is equipped with special fittings.
• When opening, the free flap opens first, then the shtulpovaya one. This should be taken into account when designing: the shtulp is placed on the sash that you use less often.

Important! The shtulp can be placed on the right or left sash — accordingly, the type of opening changes. Also, when designing a double-leafed window, one sash can be made pivotable for ventilation.

Hardware mechanisms

In the production of shtulpovyh windows and doors, designers have to solve a difficult task — at the same time to ensure the possibility of opening a single opening and tight fit of the two flaps to each other. Standard fittings will not work here — therefore special mechanisms are used.

• Shtulpovye scissors. A complex lever connected to a locking mechanism is mounted on the sash with a shtulp. When opening, you need to take hold of the lever and pull it up — then the mechanism will unlock and the shutter can be opened.
• Shtulpovy latches. They work according to the principle of the latch and simply hold the shtulpova sash in the closed position. Usually it is enough to press the button, and then pull down the released lever — as in the case of scissors, the shutter will be unlocked.

Both scissors and latches have a sufficient margin of safety, and therefore differ mainly in appearance — someone likes an almost invisible latch more, someone is satisfied with scissors with their large lever. The burglar resistance of both mechanisms is at the level, and with proper adjustment, a tight fit of the sash to the frame is ensured for good heat and sound insulation. The only important difference is that the shtulp fittings cost a little more.

Where do they put shtulpovye windows and doors?

A shtulpovy window with a wide opening, as well as a shtulpovy door without a vertical partition are really convenient to operate:

• Shtulpovy windows are most often put on balconies and loggias. Firstly, it provides an excellent overview. Secondly, there is unhindered access to the underwear hung out to dry.
• In places with high traffic, the shtulpova door allows you to adjust the flow rate. Few people — one door is open, many people — we open the second one with one movement, expanding the passage twice.
• When decorating the exits to the verandas and terraces, shtulpovye doors are also used. In summer, both doors open and remain open throughout the day — so that the veranda or terrace becomes almost a full-fledged living space combined with the house.

In addition, the shtulp "saves" the width of the window, because it is used where it is impossible to install an impost — in the manufacture of narrow and non-standard windows.

What you should pay attention to

Firstly, the shtulpovoe window opens completely — and this should be taken into account when choosing a mosquito net. It is optimal if the mesh covers the entire opening: then, in any case, the room will receive protection from insect penetration.

High requirements for the quality of installation should also be borne in mind. The shtulp is a little more "capricious" compared to a standard window — therefore, its installation should be entrusted to highly qualified craftsmen.

At the same time, a shtup window is almost the only design (in certain cases, a sliding window can serve as an alternative), which provides full opening of the opening without partitions. Provided the correct configuration and high-quality production, a window or door with a shtulp will be very convenient and at the same time quite reliable!
