Are you going to use glass on the porch? See best practices and care

Closing the apartment’s balcony is a very popular measure that guarantees many benefits. In addition to adding value to the property, the work creates an excellent space for the residents’ leisure, protecting those privileged square meters from noise, wind and rain.

But, like any work, closing requires some care. The use of glass on the balcony requires attention to ensure the area’s safety and functionality, and you must also be alert to what the law says, as not everything is allowed when closing the space.

That’s why we’ve prepared this little guide on using porch glass. Check out the types of structure that can be used in closing and tips for not having problems!

Advantages of the closed porch

The use of glass on the balcony to close the room guarantees a series of benefits. This is not a purely aesthetic decision. Residents gain in comfort, and the property appreciates. Check out some of the advantages:

More space

With the balcony closed, the apartment gains amplitude. With the integrated room, the room grows, as does the total floor area of ​​the property.

After closing, there are different architectural options to choose from. You can transform the balcony into a gourmet space or simply expand the living room, creating different environments.

Comfort

Those square meters previously subject to wind, rain and outside noise are now used as a privileged living space, excellent for receiving guests.

Free from the action of bad weather, it is possible to occupy the area with furniture that cannot be wet, for example, or even make a space for TV. It will depend on the creativity of the project.

Easy installation

For those who want to change the face of the property without major works or a lot of costs, the use of glass on the balcony is an excellent option. There are different closing systems that can be applied to practically all types of balconies.

Closing Types

There are three main ways to close the porch with glass:

European system

This is currently the most popular model, mainly because it allows the opening of the entire span and can be applied to all types of balconies. It works by means of a single rail, through which all the glass sheets run.

With the porch open, these sheets of glass line the sides of the span, rotating on the rail at a 90-degree angle, opening like doors to the interior of the porch.

It is a model that offers a lot of lightness to the environment. Felt strips between the glasses ensure sealing, preventing the entry of water and wind. But for that, your installation must be very well done.

Stanley System

In this model, the number of glass sheets and rails varies according to the size of the porch span. When the space is open, all plates are hidden under a fixed panel. It’s a model that works well in windy areas.

Versatik system

The reduced span opening compared to the European and Stanley models is the main disadvantage of the versatik system.

In reality, it works like a large window, in which the blades located on the sides are fixed, and those in the center run on a single rail.

It is, however, quite safe when it comes to sealing off rainwater.

Types of Glasses

There are also several types of glass that can be used to close the balcony, each with a different application. Meet some of them:

Seasoned

It receives thermal treatment, which guarantees greater resistance. In addition to being difficult to break, when this happens, it breaks into small pieces, generating no splinters.

Laminate

With good resistance and very efficient as an acoustic insulator, laminated glass is also safe in case of breakage, as it is formed by sheets arranged in a kind of screen, which contains the fragments.

Double

Offers excellent thermal and acoustic insulation. Therefore, it is successful in closing balconies. It consists of two glass plates separated by silicone.

Thermoset

It is more resistant than common glass but not as resistant as tempered ones.

Installation precautions

Regardless of the closure model chosen, one of the fundamental points to assess is the security provided to residents.

In 2014, the Brazilian Association of Technical Standards (ABNT) published NBR 16,259, which establishes the standards for the installation of glass on the balcony.

The standard establishes from the necessary requirements for the installation of the system to the way of calculating its impact on the building structure. Therefore, it is essential, when choosing the company that will close the balcony of your property, to verify that the project follows what is established by NBR 16,259. This is a way to guarantee the security of your home.

Keeping an eye on the law

Before closing the balcony, it is very important to check what the law says. Although few people know it, apartment balconies are not considered private areas of buildings, but part of the facades of buildings.

Both the Civil Code, through article 1136, and Law 4,591/64, the Condominiums Law, establish rules for the execution of any change in the facade of buildings, and this covers the entire area of ​​the balcony that is visible from outside the building, including the inner walls.

The legislation is less strict with regard to changes aimed at the safety of residents, such as the installation of safety nets. The remainder must be authorized by the joint owners at the meeting, with due registration in the condominium agreement.

In addition, as it is not considered a useful area of ​​the apartment, the balcony is not included in the IPTU calculation. In theory, the closure expands the property’s size, being the same subject to readjustment of the tax.

However, this change in calculation often runs into technical difficulties, such as the lack of inspection. Also, legislation varies from city to city.

In any case, before closing, it is advisable to consult the provisions of both the condominium convention and the city hall, to avoid headaches in the future.

These are the main precautions that must be taken when deciding to use glass on the balcony to close the room, a way to enhance the property and ensure more comfort for its residents.
