The service of replacing cold glazing with warm glazing on loggias and balconies is in demand everywhere today. This is due to the fact that most new buildings today are delivered with glazed balconies, the quality of which is often not satisfactory for the owners:

• window systems are ventilated;
• leak;
• they have poor sound insulation;
• and they don't keep warm.

It is impossible to use such a loggia for its intended purpose in the rainy season and in the cold season.

The difficulty of replacing glazing is that it is necessary to preserve the appearance of the facade of the house, that is, the work must be carried out without changing the appearance and without additional approvals from the management company.

Considering all the current aluminum window systems from foreign and domestic manufacturers, we can distinguish four main types:

1. cold window systems;
2. warm systems;
3. cold-warm systems;
4. hybrid systems (cold and cold-warm options are combined, and frameless glazing is often used).

If you are lucky and the balcony or loggia is glazed in a warm version, you don’t have to worry. However, the likelihood of encountering this kind of advantage is very small, since the cost of such an installation is quite high.

Most often, in new buildings, a cold system is used for glazing loggias and balconies, less often a cold-warm one. The main difference between cold and warm glazing is the following: the first is used only for the design of non-residential premises, since it has a low heat transfer resistance. A more common option is a cold-warm system. It can use not only single glass, but also a warm filling, which can be either a sandwich panel or a thicker double-glazed window. If you thermally insulate an aluminum profile, you can keep the room warm.

Whatever glazing system is installed, from panoramic to conventional, it has its own characteristics that will play a significant role during further work. Our company’s employees are fully versed in modern technologies for glazing balconies without changing the appearance of facades and guarantee quality services.

Seven reasons to replace cold glazing with warm glazing

1. You no longer have to worry about drafts and blowing.
2. You can easily connect a loggia with a room.
3. Obtaining a panoramic façade while maintaining the necessary sound insulation.
4. The windows will not fog up at any time of the year.
5. Protecting children from falling out.
6. Possibility of micro-ventilation.
7. The ability to change the color of the structure inside without dismantling the stained glass frame.

Approval Rules

The project is coordinated with the management company or other organization supervising the apartment building. If, during internal installation of additional insulation, communication with the management company can be avoided, then the involvement of industrial climbers will definitely require permission. Although in the first case it is worth obtaining consent, since serious insulation increases the load on the load-bearing slab.

Coordination is required, even if industrial climbers are not involved, if:

• The thickness of the filling of the façade structure changes.
• The size of the light openings is reduced (the metal-plastic profile is approximately 2 cm wider than the aluminum profile).
• The elements of the facade are structurally changed.

If all the residents of an apartment building at a general meeting decided to completely change the appearance of the building, they will not only have to coordinate the project with the owner of the building or the management company, but also contact the municipal construction and architecture authorities.

The feasibility and possibility of such reglazing is assessed by a commission of experts. If you replace the glazing without permission, fines will be imposed on the owner of the premises. In addition, in most cases he will be forced to restore the appearance of the facade at his own expense.

What is worth knowing about installing warm glazing?

How insulation will be performed depends on the original glazing design.

The cold system is often used for external and internal architectural type buildings; they do not have a thermal break. The glass is fixed from inside the room using a bead. To fully use such a camera system, a lot of modifications have to be made. There are three options for doing this:

Vanguard

The structure will be thermally separated; special thermal insulating inserts (thermal boxes) are used. They are created from extruded polystyrene foam and mounted in a stained glass window. For work, rubber seals, aluminum clamps of different sizes, and heat insulators are used. Fixation is carried out using self-tapping screws. Afterwards the clamp is hidden with a decorative cover. From the inside, you can create any design option - both wood-like and in the form of any other lamination. The advantage is that the light opening will not decrease. Additionally, upgraded fittings can be installed on new racks.

Installation of filling is carried out through the use of internal rubber seals. Fastening is carried out using aluminum clamps; they have external seals. The double-glazed window will rest on special polymer pads, about 8 cm long and 0.5 cm thick. These pads are fixed to load-bearing pads that are located on the crossbar. With this option of replacing cold glazing with warm glazing, the size of the light opening of a blind window will not change, and accordingly, the façade of the building will not change visually. If the sash is opening, then its light opening will change slightly.

Avangard premium

The structure is thermally separated when special heat-insulating rates are installed. They are made from polystyrene foam and mounted in stained glass. If necessary, individual structural elements are dismantled. Fixation is carried out on support brackets, fastening is carried out in the floor slab or vertical post of the stained glass window.

Each product receives an external RAL color that is completely similar to the original glazing. The nuance is that with this option, the light opening will decrease by about 3 cm on each side. Translucent or opaque filling will be carried out in the PVC structure itself - it is attached around the perimeter using clamping beads. In the future, if necessary, you can change any element - dismantling them is enough.

The distance between the PVC elements in the stained glass window can be decorated as desired. Both false linings and decorative covers are used. Everything depends only on the wishes of the client.

Tatprof

It must be taken into account that when insulating, the façade of the balcony should not be modified. The new model of profiles is created from PVC, for which a modern thermally insulated profile is used. If work of this kind is carried out, then it is necessary to immediately provide for all important indicators, and the color of the glazing will be determined only by the client’s desire.

If we are talking about a cold-warm system, then the installation of window blocks is carried out using rubber insulation and aluminum clamps. The latter will be fixed using screws. Decorative covers are used on the outside. In this case, the division of the facade will be carried out by installing a thermal break insert. This type of work is performed only by industrial climbers. Its implementation involves several steps:

1. The filling is dismantled, after which the existing aluminum profile on the street side is insulated. Polymer materials are used to reduce the ingress of cold.
2. Old sashes are replaced with new ones, which are created to the required dimensions using warm PVC or aluminum. Modernized premium fittings are used.
3. Double-glazed windows of the required sizes are installed and waterproofing is carried out.
4. Existing connections are subject to sealing, the stained glass window is assembled, the fittings and sliding system are adjusted, and existing debris is removed.
5. Additionally, work will be carried out to seal the existing stained-glass window joints. False racks and false crossbars are often used. It all depends on the existing project.

Insulation of profile elements

It is planned not only to replace thin glass, but also to modify the profile. Required: Remove the glass sheet. Clean the profile surface, removing silicone inserts, remaining sealant and seals. Install a new double-glazed window onto the old frame using clamping strips with thermal inserts.

The frame elements are covered from the outside with decorative covers, painted to match the color of the facade. Swing and sliding systems must be replaced. Insulation occurs due to thermal inserts. The method will not provide ideal heat conservation - it should not be chosen for northern regions, although the indoor microclimate will improve.

The advantage here is increased sound insulation, as well as maintaining the size of the window, which is important for appearance and light transmission.

We create a hybrid version from a cold-warm or cold system

The combination of several system options when glazing a balcony is quite common. A universal cold-warm system is used, and the second part can be tubeless glazing, for example, Gealan. To deal with this problem, a warm subsystem is initially created, and then the stained glass window itself is insulated. There are several options for the customer to choose from. PVC or warm aluminum can be used. The latter will fit in more organically, but PVC is more affordable from a financial point of view.

Benefits of replacement

Positive factors for installing warm glazing systems:

• By insulating a loggia or balcony, additional living space will appear in the apartment;
• The hermetically sealed connection of the structural elements eliminates the appearance of drafts;
• It will become warmer in the rooms adjacent to the balcony or loggia, which will help improve the microclimate of the apartment as a whole;
• The doors in energy-saving systems are equipped with fittings with a micro-ventilation function and child protection;
• Absence of drips, condensation and accumulations of dampness, regardless of seasonal climate changes;

Replacing cold glazing with warm glazing – what should you know about the price?

The final cost of the work will always be influenced by several indicators. These include:

• total stained glass glazing area;
• sashes, their type, number. They are created from different aluminum or PVC profiles and have different fittings;
• type of insulated system, options for strengthening, filling stained glass, and so on.

If we consider the standard option for reglazing, which uses double-glazed windows, argon and energy saving, then one square meter will cost approximately 5,000 rubles. When creating an opening sash that has a tilt-and-turn mechanism made of PVC, the price starts from 6,000 rubles. Size, painting, window sills, and tides all play a role. From 15,000 rubles, work begins on creating a warm aluminum sash with slopes, canopies, and awnings.

Extension of profile parts

This technique is almost as good as completely replacing the window glazing. To do this, you need to remove the glass and clean the profile elements to perfect smoothness. The frame base is further strengthened.

A new thickened and insulated frame with thermal inserts is placed on top of it. If there is a discrepancy between the internal profile strips, the old ones are removed. Double-glazed windows with 3–5 chambers are placed inside the frame. The height of the frame is adjusted using aluminum profile extensions.

When adding profile elements, gaps usually form, which are covered with decorative overlays, flashings with clips for fastening, and clamping strips. The advantages of this method are high thermal insulation, noise protection and ease of repair: glazing elements can be easily removed.

At the same time, the work will cost less than completely replacing cold windows. The disadvantages include a decrease in the transparent part, and, accordingly, light transmittance. But with the correct selection of the frame width, the disadvantage can be minimized.

What should you consider while working?

• What is the thickness of the glass, is there tinting on it, original dimensions, wind load.
• Are there nodes that could become conductors of cold in the future?
• What is the height of the upper and lower crossbars, will there be problems in the future during insulation of the floor or ceiling.

Based on the selected profile and size of the glass unit, the approximate classification is carried out into the following categories: budget, standard, comfortable option. In each case, the following type of glass unit is used:

• strained glass;
• triplex;
• tinted glass.

Selecting materials for a new window

For warm glazing, aluminum structures or plastic double-glazed windows are suitable.

Aluminum double-glazed windows - light and durable

Advantages of the first option:

• increased strength;
• no deformation due to temperature changes;
• anti-corrosion qualities.

Since aluminum frames weigh little, the load-bearing plate will not be overloaded. New glazing will last a long time and will reliably protect against heat loss and street sounds. But installing windows is quite complicated, and the material itself is expensive.

Plastic windows are inexpensive and easy to install

Plastic is inexpensive and easy to maintain. Windows are not difficult to install; you can even do it yourself. Double-glazed windows will protect from cold and noise, but are prone to condensation. Plastic structures weigh a lot: they can only be mounted on a concrete or stone base.

If you have the means, you can install wooden-aluminum windows. The frame here is made of durable wood, covered with aluminum overlays. A standard double-glazed window is inserted into it. Wood allows you to avoid “cold bridges”, and metal protects it from the effects of external negative factors.

Wooden-aluminum models retain heat best

In addition to the glazing material and fittings, you need to choose the right paint for the frames. New window structures will have to be painted the same color as the old ones, so as not to disturb the design of the facade.

When selecting material for windows, pay attention to the absence of external defects on the glass and profile:

• chips and cracks;
• frame distortions;
• glass cloudiness;
• differences in thickness.

Experts do not recommend installing plastic double-glazed windows on aluminum frames or performing warm-cold glazing in one opening. This will lead to increased heat loss, fogging of windows and micro-leaks of moisture. The latter is fraught with the appearance of mold and fungal growths on the walls and ceiling.

Replacing cold glass with double glazed windows

To obtain good thermal insulation, a double-glazed window is used that has an energy-saving function and is filled with argon inside. Due to this, heat-saving indicators will increase, and as a result, being in the room will be more pleasant, and part of the solar energy will be reflected back.

If we are talking about the glass of the bottom row that comes from the floor, and you want to make them transparent, then you can install an impact-resistant “triplex” model. It has at least two glasses that are laminated with a special film. At the moment of damage, they will not fly apart, but will remain on an adhesive basis. This is especially true if there are children in the house.

A very important point is that the replaced element fully matches the original façade tinting. It happens that clients choose film tinting if they want to hide prying eyes from the street. It will be applied from the inside of the glass unit during its creation. If a plastic thermal insulation frame is used, the possibility of cold bridges is eliminated.

When the cold glazing of the balcony is replaced with warm, you can move on. Now, after delimiting the balcony and dismantling the walls, you will be able to add square meters to the living room or kitchen. If you leave the walls, you can organize a small home office on the balcony.

Tip: If you want to arrange a separate room on the balcony, then expand the heating system or install a heated floor. Then the temperature in the room will be truly comfortable and equal to the general temperature throughout the house.

Warm glazing saves the corners of the balcony from freezing and excessive humidity. This means that there will no longer be musty air, penetrating drafts or mold in the room. The last problem is especially relevant for balconies in cities with a humid climate like St. Petersburg or Kaliningrad.

Warm glazing is a guarantee of a good microclimate in the house, a barrier to cold winds and precipitation, blocking the path of drafts and frost. A team of specialists, which includes industrial engineers, will help install it. climbers, and if you equip a budget option like a secondary circuit, then you can do it on your own.

If you want to radically change the balcony, you need to negotiate with the relevant department, but repairing the glazing without changing the facade is much faster and less labor-intensive.

The Correct Windows factory manufactures, sells and installs high-quality plastic windows and doors at affordable prices in Moscow and the Moscow region. PVC windows will relieve street noise for many years, retain heat in severe frosts, and a clever double-glazed window (with silver coating) will not let the heat and heat into your home in the summer. A good solution for those who want to make their windows inimitable and unique would be a stained glass unit with an exclusive pattern.

Documents for applying to the Criminal Code

Having prepared the project, the owner of the premises must write an application to the Criminal Code to carry out the work. In addition to the project documents, the following must be attached to the application:

• an extract from Rosreestr on ownership or a copy of the certificate;
• a certificate stating that there are no debts for utilities;
• copies of certificates for materials to be used in glazing;
• guarantee of the contractor who will perform the work.

If you plan to perform high-altitude work, you will need confirmation that the company’s personnel have permission to carry out such work.

Installation of double-glazed windows in a mullion-transom system without changing the size of the facade

To improve the heat capacity properties, in some cases it is possible to replace the windows on the balcony without dismantling the entire unit, but only the double-glazed window. Reglazing of balconies is carried out in 9 stages:

1. Removal of masking overlays.
2. Removing the pressing profiles and fixation strips.
3. Removing glass.
4. Thermal insulation, for example, sandwich panels.
5. Replacement with double glazed windows.
6. Sealing joints.
7. Return of fixing strips.
8. Installation of compensators.
9. Decoration.

In this case, all stages of work are carried out outside. This should be taken into account in order to avoid traumatic situations in advance. After installation, the intensity of the light flux does not change, the glass area does not change significantly.

How to insulate a balcony yourself and is it possible?

An architectural element such as a balcony is initially classified as cold. Often apartment owners want to expand their living space due to its area. To do this, you need to carefully understand how to insulate a balcony so that it meets all the requirements for residential premises.

Thermal insulation includes several mandatory stages. Professional builders will cope with this task faster. But if you are not in a hurry and want to be one hundred percent sure of the quality of the work performed, you can do it yourself.
