Important points in terrace and balcony insulation

Creating functional areas on flat roofs can be highly appealing for various types of structures. Balconies and terraces offer apartment dwellers an opportunity to enjoy the outdoors while still being above ground level. When these balconies are constructed as livable spaces, they become integral parts of the building's thermal envelope. Consequently, it is crucial to ensure proper insulation for these areas.

The importance of terrace and balcony insulation

Typically, balconies and terraces in apartments are adorned with stone, ceramic, or tile flooring. Additionally, these areas are often subject to washing, necessitating proper insulation. Inadequate moisture insulation in balconies can lead to moisture seepage into lower surfaces or the interior of the building, resulting in irreparable damage, especially during cleaning or in inclement weather conditions such as rain or snow. Therefore, it is essential to incorporate waterproof insulation not only in the roofs and interior areas like bathrooms and toilets but also in all terraces and balconies during the construction of apartments. This measure significantly extends the lifespan of the building.

How to perform waterproofing on the terrace

As mentioned previously, incorporating moisture insulation in terraces and balconies is crucial to prevent moisture infiltration into the building structure. Therefore, waterproofing should be carried out before the completion of terrace and balcony construction. The following steps are involved in terrace and balcony insulation:


Moisture insulation is installed beneath ceramic or mosaic coverings. Therefore, it should be applied as the initial step before any surface work. This process involves removing any small or large imperfections, adhesive residues, protrusions, and depressions to create a completely even surface for the application of waterproofing materials.

Installation of Waterproof Strips

Given the higher water consumption and washing frequency in balconies and terraces compared to roofs, it is essential to prevent water accumulation in the corners. Waterproof strips should be utilized along the middle border of the floor and the wall. These strips are highly flexible, enhance water resistance, and maintain their elasticity over many years.

Waterproofing Implementation

Waterproofing is one of the most effective moisture insulators used for sealing various structures, particularly roofs. Waterproofing exhibits exceptional resistance against humidity and moisture penetration, remains unaffected by direct sunlight, and demonstrates durability and strength. Utilizing Waterproofing is an excellent choice for sealing balconies and terraces. This task should be entrusted to professional technicians and installers experienced in this field.

Implementation of the last layer

After installing Waterproofing on the surface of the balconies, a mosaic or ceramic layer is applied on it. In order to increase the durability of the balcony bed surface against water and also the pressures on it, it is better to apply a protective layer as the last layer on it so that it is resistant to external damages.

Important points of insulation in the balcony and terrace

When it comes to balcony and terrace insulation, several important points should be taken into consideration:

Use High-Quality Materials

It is crucial to use high-quality raw materials for insulation. Low-quality materials lack durability and longevity, and they are prone to deformation and issues when exposed to harsh weather conditions and pressure. Therefore, it is recommended to utilize premium waterproofing products like Waterproofing for effective insulation of balconies and terraces.

Seek Professional Expertise

Insulation installation in balconies should be carried out by experienced and professional technicians who specialize in this field. Proper insulation requires adherence to principles and compliance with standards. Failure to follow these guidelines may result in inadequate insulation, leading to moisture penetration over time. Technicians in this field have undergone necessary training related to moisture insulation installation on various structures and possess knowledge of the required standards for effective implementation.

Follow the Defined Steps

Insulation should be implemented according to the prescribed steps. Failure to follow any of these steps during waterproofing can compromise the final outcome and result in incomplete balcony insulation.

Pay Attention to Lining Height

Technicians and installers should pay attention to the height of the lining beneath the bed. Similarly to roof waterproofing, Waterproofing should be extended onto the walls, reaching up to 10 cm on the edges. This practice enhances the balcony's resilience against damage.

Insulate Door Proximity

Apart from the wall edges, all other areas of the balcony that are close to the door should be insulated to enhance their resistance to external factors.

By adhering to these points, you can ensure effective and long-lasting insulation for your balcony and terrace.

There are several advantages to using waterproofing in balconies and terraces:

  1. Enhanced Resistance: Waterproofing increases the floor's resistance to sunlight, moisture penetration, and chlorine ions. This helps protect the balcony surface from the damaging effects of these elements.
  2. Chemical Resistance: Waterproofing also enhances the balcony's resistance to various chemicals and household detergents. This ensures that the surface remains unaffected and maintains its integrity over time.
  3. Dust and Pollution Prevention: A properly waterproofed balcony and terrace surface does not absorb dust and pollution. This helps keep the area clean and reduces the need for frequent cleaning.
  4. Easy Cleaning: Waterproofing allows for frequent washing of the balcony and terrace without the risk of moisture penetration. This makes maintenance and cleaning of the space hassle-free.
  5. Increased Durability: By providing a protective layer, waterproofing increases the durability, longevity, and overall lifespan of the balcony and terrace. It helps the surface withstand wear and tear, ensuring its longevity.

Waterproofing offers numerous advantages, including increased resistance to sunlight, moisture, chemicals, and pollutants, easier cleaning, and improved durability of the balcony and terrace surfaces.

Both bitumen 60/70 and bitumen 80/100 can be used for waterproofing, but the choice depends on specific factors and requirements. Here's a brief comparison:

  1. Bitumen 60/70: This grade of bitumen is commonly used for waterproofing applications. It has a lower viscosity compared to bitumen 80/100, making it easier to work with during application. Bitumen 60/70 offers good waterproofing properties and is suitable for moderate temperature conditions.
  2. Bitumen 80/100: This grade of bitumen has a higher viscosity and is more resistant to deformation under high temperatures. It provides better waterproofing performance in hot climates or areas with high-temperature variations.

When selecting between bitumen 60/70 and bitumen 80/100 for waterproofing, consider the following factors:

- Climate: If you are in a region with high temperature variations or hot climates, bitumen 80/100 may be more suitable due to its higher resistance to deformation.

- Application: Consider the specific requirements and conditions of the waterproofing project. If the project involves areas with moderate temperature conditions, bitumen 60/70 can be a suitable choice.

It's recommended to consult with a professional contractor or waterproofing specialist who can assess the specific project requirements and provide guidance on the most appropriate grade of bitumen for effective waterproofing.
