Although the vast majority of structures are equipped with shutters that swing inward, some buyers order windows that open outward. In terms of safety, these models are no different from conventional products, due to the fact that all important fittings are located on the inside of the frame. Similar modifications are still popular in Britain, the USA and Australia. Typically, the choice of such windows is determined by various factors, but for any reason you need to be prepared for some inconveniences during their operation. After all, this opening method has both pros and cons.
Which windows can be equipped with external sashes - design features
The functionality of the products does not depend on the type of profile system.
That is, opening the window outward is possible for all main modifications - structures made of PVC, wood and aluminum. This is achieved through the use of a special profile with a T-shaped section. In addition, the frame is manufactured and installed in a mirror design to take an inverted position in the opening. This installation method is necessary so that the doors swing open towards the street. Outward-opening models can be equipped with both traditional doors and transoms. At the same time, roof windows should be included in a separate category, more details about which can be read on OknaTrade. Standard models provide the possibility of using fittings for tilt-and-turn opening of the sashes.
When installing the structure in openings with a quarter, it is necessary to take into account the specific configuration of the walls. In such cases, so that the sashes can open/close freely, the overall dimensions of the windows are reduced by this quarter. Then, during the installation process, the issue of the resulting void between the frame profile and the wall has to be addressed.
Integrated window into the facade with the installation of a standard double-glazed window
| Rice. 3. Integrated window into the facade with the installation of a standard double-glazed window |
This option of an integrated window involves the installation of a standard rectangular double-glazed window, in which an aluminum strip 41 mm wide is formed on the outside. Installing a standard double-glazed window with a thickness of up to 38 mm can significantly reduce the cost and simplify the assembly of the finished product.
This design uses new sash profiles AYPC.F50.1303 (for top-hung opening) and AYPC.F50.1305 (for parallel-sliding opening), as well as a new sash pressure plate profile AYPC.F50.1612, which is fixed to the sash using self-tapping screws 3.9x13, and seal FRK69.
Thanks to the use of 34 mm multi-chamber polyamide bridges in the AYPC.F50.1303 and AYPC.F50.1305 sash profiles, the thermal conductivity of the typical frame-sash section is reduced to Uf=2.6 W/(m2*K).
Areas of application for outward-opening windows
Such models are usually chosen for installation when it is necessary to save space indoors.
Opening the window to the outside can solve the problem of lack of space on glazed balconies and loggias. It is also recommended to use such modifications when installing a wide multifunctional window sill - in such cases, tearing the sashes inward creates many problems, since objects have to be constantly removed from the window sill-tabletop. These models are also installed in openings separating balconies or loggias from interior spaces. Some customers choose windows with external sashes in cases where they are going to additionally equip them with automatic remote opening systems. Under such circumstances, any objects on the window sills and even curtains can interfere with the normal functioning of the electric drives. To prevent suddenly changing weather from presenting an unpleasant surprise, you must immediately install wind, rain and sun sensors, as well as connect windows to the Smart Home system. If it is missing, then you can create a stand-alone control unit for windows only.

Why is this type of opening still in demand?
When washing or opening the sashes for ventilation, it is not necessary to remove and move everything away from the window and clear the window sill.
A matter of habit is quite a strong argument for many. People, especially older people, have a hard time accepting the slightest changes in their lives, even in small things. Therefore, if the owner of the house is elderly or adheres to conservative views, then it will be more common for him to install identical structures, only new ones. And life will flow the same way, but in a more comfortable direction for him.
Another option why this opening principle is used is the technical features of the window opening. Sometimes, in order not to completely remodel it, it is enough not to seriously change anything except new frames and its internal components, glass or double-glazed windows. This saves the buyer money and time.

A block is made from wood boards, dry. This makes the block wear-resistant and does not move or twist.
Opening outwards to the street is convenient and does not take up space. Sometimes this opening option is very relevant. But we recommend fixing the doors in windy weather; they can close abruptly, damaging something or someone.
Outward opening window options
- Single blocks, windows facing out
- Veranda blocks outwards
- Double blocks where the outer frames open outward and the inner ones inward.
What to remember when installing outward opening windows
It is necessary to install latches (hooks) that will be located on the inside of the window and hold it in the open position. They will help prevent its involuntary closing during windy conditions.
- To better secure the window in the closed position, you may need a latch or a bolt on the outside of the window. This is acceptable if it is on the first floor.
- It is recommended to install anti-vandal fittings and the same glass or double glazing. To minimize the likelihood of penetration.
- If a mosquito net is needed, it must be removable,
- It is recommended not to make large sashes in order to simplify the issue of washing them later.

Benefits of outward opening windows
It is not only the need to save indoor space that is the reason for choosing these models. This opening method has other important advantages:
- the possibility of organizing effective and controlled ventilation of interior spaces;
- increased tightness of the structure - in bad weather with strong winds, the sashes are pressed inside the frame, so such windows are almost never blown out.
The casement window, whose sashes also swing outward, has another additional advantage. In such modifications, the frame does not have a stationary vertical impost, so that when two sashes are opened simultaneously, the light opening is not divided by any jumpers. You can learn more about frame windows from the feature article on OknaTrade.
Since such products are additionally equipped with special fittings that limit travel, there is no need to worry about the doors slamming shut during sudden gusts of wind.
Approximate prices
The inverted profile, which is used in the manufacture of windows with external opening, has a fairly impressive cost, so windows made from it are significantly different in cost from ordinary windows. To understand the cost, we calculated some sizes. The windows you need can be any size.

Disadvantages of outward-opening windows
Along with the advantages of opening the doors towards the street, there are also disadvantages. If such aluminum, wooden or plastic windows are chosen, outward-opening sashes will not allow the use of traditional mosquito nets. To protect yourself from insects, you will have to install internal roll models. In addition, there may be problems with cleaning the outside of the windows. They are usually solved by installing sliding or hinged hinges that allow the sash to be rotated around its axis. When this option is not suitable, self-cleaning double-glazed windows are installed.
When installing such window modifications, it must be taken into account that roller shutters or vertical awnings cannot be installed inside the outside of the opening. Usually the products are made overhead and mounted on the front of the house.
Smoke exhaust hatch system
| Rice. 6. Smoke exhaust hatch system |
One of the elements of inclined facades are opening structures, which are used to equalize pressure outside and inside the room, provide ventilation and smoke removal.
Hence the names of these windows - smoke exhaust hatches. Like any other window, the hatch includes a frame, a sash, a clamping element for fixing the glass unit, connecting corner elements, a sealing system, and various piece components (linings, plugs, etc.).
This design assumes the use of fillings up to 38 mm thick. To optimize warehouses, many of these elements are borrowed from other ALUTECH systems.
The system provides the ability to assemble the frame and clamp in two ways: the crimping method and using 5x10 pins. Assembly of the sash structure is carried out only using pins. When installing the infill, the connection between the clamping and sash structures is made using 4.2x32 self-tapping screws.
A hidden fastening option allows you to obtain an aesthetic appearance of the structure, protect the fasteners from aggressive environmental influences and prevent the penetration of atmospheric precipitation into the structure. Considering that non-rectangular double-glazed windows are often used in complex spatial facades, the smoke exhaust hatch system allows for the assembly of trapezoidal structures.
This became possible thanks to the addition of the ALUTECH frame systems with the AYPC.W62.0960 corner hinge insert, while the assembly of frame corners, sashes and clamps is carried out exclusively using pins.

Requirements
Requirements are determined according to GOST 30777-2012. There are several important points to note here :
- the folding devices must include appropriate components of the mechanisms;
- folding devices are used mainly for balcony blocks; the opening angle should be limited to 20 degrees;
- sash control with one handle;
- the dimensions of the devices are established by working drawings at the factory;
- moving parts of devices must move without jamming;
- The design of the devices must allow them to be replaced.
It also says here that the design of the product must ensure reliable fixation of the sash in the “ventilation” mode.
How to open a plastic window from the outside - several ways
In some situations, it is necessary to resolve the issue of how to open a PVC window from the outside. And in such a way that there is no such thing as a plastic window opening incorrectly.
Opening a plastic window yourself is not as difficult as it seems
Similar cases occur when a child locks an adult from the inside or the keys are forgotten in an apartment (or house). In this situation, one of the ways to open a PVC window from the outside is to use a special object.
There are several ways to open a plastic window from the outside. This can be done using a thin metal plate or an iron ruler. You can also use a regular screwdriver.
IMPORTANT! If you have a window with classic fittings, then opening it from the street will not be difficult; you just need to study this standard mechanism.
How to open a window from the outside with a screwdriver
If you decide to use a screwdriver to open the window from the outside, then you need to do this in the place where the latch is located. That is, press the sash of the plastic window. And then open the sash by pressing on the fittings (see the article “Fittings for plastic windows”). Now the sash will open a little - you can turn the handle of the locking mechanism.

How to open a window from the outside with a ruler or plate
If you have a ruler or plate, the design of a window opening outward will be completely different. So, any of these tools needs to be placed between the frame and the glass unit, reaching the latch. And then, hook the latch with this object and pull it down.
Opening the window this way will not be difficult, since plastic is a flexible material. As a result of these efforts, the plastic window should open correctly.
Opening a PVC window with a ruler from the outside
However, all these methods are suitable only in situations where there is no handle with a lock on the window. If there is one, then you won’t be able to open the window from the street yourself.
Another, but much more difficult method of opening a PVC window from the outside is drilling a hole. This is necessary to use a screwdriver or a pen to open the window through the drilled hole. However, this method is exactly what thieves use to open windows, since this damages the structure.
Opening a window through a drilled hole is not the best way
Smoke exhaust hatch system with improved thermal characteristics
| Rice. 7. System of smoke exhaust hatches with improved thermal characteristics |
Compared to the previous solution, the new design of smoke exhaust hatches for energy-efficient facades (installation of double-glazed windows up to 50 mm is allowed) has a number of structural and aesthetic advantages:
- improved heating technology
Polyamide thermal bridges 34 are used in the frame and sash profiles. The legs of the thermal bridges make it possible to create a multi-chamber space in the insulating zone of the sash; the thermal insulation chamber of the frame is filled with foam liners made of a material with low thermal conductivity. The FRK64 middle seal has a massive body with several chambers, which allows you to create a serious barrier in the space between the frame and the sash. All this made it possible to significantly increase the thermophysical properties of the hatch and obtain the thermal conductivity of the profile unit “facade rack - frame and hatch leaf” at the level of Uf = 1.979 W/(m2 °K).
- reinforced frame and sashes profiles for the manufacture of large structures
The frame and sash profiles have high strength characteristics; to obtain the necessary rigidity, an additional rib is introduced into the frame chamber. This makes it possible to produce window structures with dimensions of more than 2 m in height and width.
- the minimum possible protrusion of the hatch relative to the plane of the facade
In the front area of the hatch there is a fitting groove and an area for installing a hinge group. This area was reduced to the maximum size, as a result of which the hatch structure protrudes relative to the main facade by only 31 mm, which is almost invisible on inclined structures.
