General rules and nuances

Aluminum glazing is the better choice for any object with a weight limit, including balconies and loggias on older homes.
These structures are the lightest while still having the highest durability, which makes this possible.
Installation restrictions are essentially nonexistent for such designs.
Aluminum is a lightweight material with exceptional strength and resistance to corrosion. It is therefore a preferred choice for installation on homes situated in regions with strong winds and high humidity levels.
Crucial! Such structures need to be more resistant to heat and water depending on the operating conditions. This is accomplished by using contemporary glass blocks and hermetic seals.
Basic specifications set forth by GOST for using aluminum blocks to glaze balconies and loggias:
- Heat transfer resistance, over 11 m 2 *S/W.
- Sound protection, over 25 dBA.
- Light transmittance, 0.66 – 0.76.
- Air permeability at DR = 10 Pa, from 5 to 15 m 3 / (h.m 2).
- Minimum opening-closing cycles, over 15,000.
- Wind load resistance, not less than 200 Pa.
- Operating period of at least 50 years.
- Environmentally friendly for use in residential areas.
- Versatility, ability to operate at temperatures from -50 to +50 C.
Such structures have to be aesthetically pleasing; coatings must be applied with powder coating to produce a coating that is extremely resistant to aggressive influences.
What tools will you need??
The tools needed will vary based on the installation technology and the nature of the work involved, including whether or not the old balcony glass block needs to be disassembled.
In most situations, you’ll need the following equipment:
- A crowbar is used to dismantle the old window block.
- Hammer for making dowel fasteners, knot fitting, for dismantling operations on old frames.
- Chisel for dismantling work on the frame, as well as removing old ebb and window sill structures.
- Wood saw, for cutting an old wooden frame, to simplify dismantling.
- Measuring tools: tape measure, ruler, angle and level.
- Screwdriver for tightening screws and other fasteners.
- Screwdriver with bits.
- Electric drill with concrete drills for making mounting holes in walls.
- A set of hex keys for assembling and adjusting the operation of the window unit.
- Gun for silicone sealant and construction foam.
Step-by-step instruction

A balcony is not the same as a loggia because it has handrails, a balcony slab, and it extends beyond the outer wall. As a result, the balcony structure above limits the height of the balcony.
Because aluminum glazing is lightweight and won’t put undue strain on the balcony slab, it is especially preferred in this embodiment.
It will be necessary to disassemble any old wooden frames that may have been installed on the balcony. In order to prevent the disassembled structures from falling over the balcony, the work must be done by at least two persons. Take out the glass and sashes and then take apart the wooden box; you can use a hacksaw to cut it into pieces if needed.
Crucial! In order to improve the wall’s future adhesion to the mounting foam, carefully remove any debris after disassembling the wooden frame, clean the walls of foam and concrete mortar deposits, and prime the aluminum frame’s future junctions.
You must meet several requirements in order to receive long-lasting aluminum balcony glazing and high-quality results:
- Before installation work, check the fastenings to the load-bearing wall for strength. If a crack is found in the concrete slab, it must be strengthened or even replaced completely.
- For minor damage, a simple cement screed can be applied.
- If, during the inspection, damage to the reinforcement frame due to corrosion is discovered, the balcony is strengthened with iron beams, concreted into the wall and a reinforcing mesh is welded to the structure.
- During the installation process, do not allow the frame structure to bend.
- Installation on balcony handrails is allowed only if the metal parts of the balcony structure are strong, otherwise it is reinforced with an additional metal structure.
- If the balcony is glazed with the frame extended, it is first sheathed, then aluminum glass blocks are installed on a strong base.
- Pipe stands are placed in the structure of a hanging balcony that does not have an upper ceiling.
- If the length of the balcony exceeds 4 m, additionally install a pipe stand in the middle.
- The supporting frames are made of iron corners, which are painted after thoroughly cleaning the surface and degreasing.
- It is required to make horizontal butt joints of the upper and lower parts of the frames.
- The largest width for a balcony box that is taken outside is 1.5 m.
- Aluminum window structures are fixed to the walls only with the use of mounting strips.
Balcony glazing technology using aluminum glass blocks:

- The protective canopy is installed along the top line after dismantling the old structure and removing debris from the balcony room.
- Installed at the level of the base under the frame, usually a metal profile.
- The mounting plate is strengthened on the outer side of the aluminum frame using self -tapping screws.
- The second side of the plate is strengthened to the outer wall with anchors. The number of plates depends on the size and mass of the frame with glazing, but, as a rule, manufacturers advise them to do at least 70 cm.
- Install the windowsill.
- Remove the wings from the frame.
- Align the frame vertically and horizontally, with wooden wedges, after which the mounting plates are attached to the base.
- Fill all the cracks with construction foam.
- Put on the wings and start setting up the work of mobile parts of the structure.
- After 24 hours, the remains of hardened foam are removed.
- Protect the seams from UV rays and natural precipitation, painting or using special protective plates.
- Internal finishing work and thermal protection is performed after the installation of the window block.
Differences in the process of installation for the loggia
The building’s walls enclose the loggia, which is raised on a solid floor slab.
Vital. Because it is a crucial component of the entire house and can support a heavy weight, it cannot collapse. It is not possible to exceed the total weight limit in spite of this.
The loggia’s installation includes aluminum frames:
- The base for installation is carefully prepared, it must be level, in some cases the level is raised using foam concrete blocks.
- The aluminum system is installed on the parapet before laying the window sill.
- Corner, end and intermediate posts can be made of timber.
- Secure the support posts to the top and parapet with corners and self-tapping screws.
- Remove the glass unit from the frames.
- Remove the sashes.
- Fix the support profile at the bottom of the aluminum frame according to the level.
- Insert anchor plates into the grooves of the block and secure the structure.
- Insert frames into ready-made gaps.
- Fix the frames with self-tapping screws, inserting them into the prepared holes.
- Install sashes and double glazed windows.
- Perform adjustments to the operation of mechanical components.
- They seal the seams and complete the installation with finishing work.
You can improve your living space by adding insulation, lowering noise levels, and creating a more comfortable atmosphere by installing aluminum windows on your balcony. With simple tools and a methodical approach, you can complete this do-it-yourself project and get results that look professional without hiring a contractor.
Possible difficulties
Installing high-quality glazing on loggias and balconies is not an easy task.
Vital. The first steps in the process involve measuring the frame, selecting a warm or cold profile for the design, and figuring out the structural elements.
It will be extremely difficult to fix mistakes made at these stages when the installation is underway. It is therefore preferable to hire experts for this work who are prepared to handle turnkey tasks and who will take accountability for the project’s outcomes.
Typical errors that can occur when installing aluminum windows on balconies and loggias include the following:
- The installation site for the frame was not properly prepared.
- The base level for the frame is not maintained.
- The metal base of the balcony and its slab are not strengthened.
- The frame is moved beyond the boundaries of the balcony, beyond the permissible rules.
- The canopy above the frame is not installed.
- The sealing and protection of insulating seams is not completed.
- The frame is installed skewed.
When Replacement May Be Required?
The following situations typically result in the decision to replace aluminum structures on balconies or loggias: when these structures are unable to fulfill their fundamental duties:

- Thermal protection.
- Protection from wind, rain and snow.
- Noise protection, which is very important when balconies face a noisy street.
- Does not meet appearance requirements.
- Does not provide protection for the balcony space.
- Does not provide the required lighting and ventilation mode in an apartment or house.
- The design does not allow for full maintenance of the glass block: opening/closing and washing windows, as well as sealing cracks.
Crucial!Reliable, simple to install, and energy-efficient are requirements for new aluminum frames. In order to accomplish this, you must select a design that satisfies current GOST standards for dependability and a minimum 80-year service life.
How technology changes?
The technology used to replace the windows in these two designs is different. This is because the loggia is part of the building and sits in a recess behind the outer wall cut, while the balcony extends from the wall cut of the building and is situated on a reinforced concrete slab.
Since the loggia already has three sides covered and only needs to be glazed, most options call for significantly less building materials and labor-intensive glazing procedures. The installation of this stack replacement can be completed in a single business day if the loggia is configured straight.
Since a balcony must have glazing on at least two of its sides and often three, the cost of this type of glazing increases with each square meter of the balcony.
The weight of the window structure is also important for a balcony. Since it is wall mounted and fixed to the building’s wall, the glazing cannot support more weight than is permitted on the balcony.
Urban planning guidelines stipulate that balconies installed in older housing stock may only support a maximum weight of 200 kg. The range of materials and window structure types that can be selected for them is thereby greatly reduced.
Note: To avoid going over the allowable strength when replacing windows on a balcony, it is advised to calculate the installed structure in advance.
Since load-bearing walls are the focal point of loggias, there are typically no weight restrictions on the glazing in these spaces. The owner is free to select any window unit design that best fits his needs, both practically and aesthetically.
