Terrace and balcony drains - key elements of the drainage system

Terrace and balcony drains are an essential element of every outdoor drainage system.   Their role is crucial in draining rainwater. They prevent water from accumulating on terraces and balconies. This protects the structure from damage. At Onninen, we offer a wide selection of high-quality drains. They come from renowned manufacturers such as HL and Kessel.

We often come across the question about the differences between terrace and balcony drains. Terrace drains are usually larger and have higher efficiency. They are designed to drain larger areas. Balcony drains, on the other hand, are smaller and more compact. They are ideal for the limited space of balconies. However, both types have a similar task - effective water drainage.

Types of terrace and balcony drains available at Onninen

Our offer includes various terrace and balcony drains. They are divided into several main categories:

• Vertical drains - drain water directly downwards
• Horizontal drains - ideal when lateral water drainage is needed
• Attic drains - mounted on walls and attic walls
• Two-piece inlets - with a separate body and cap

The key element when choosing an inlet is its capacity and diameter.   Larger diameter drains, such as DN100, provide higher throughput. They are ideal for large terraces. For smaller areas, DN50 or DN70 drains will be sufficient. It is also worth paying attention to the material of manufacture. Plastic drains are lightweight and corrosion-resistant. Stainless steel models are highly durable.

In everyday practice, we see a growing interest in drains with additional sealing. They provide better protection against leaks. This is especially important in the case of terraces above living spaces. It is also worth considering drains with a sealing collar. They facilitate the connection to waterproofing.

Criteria for selecting terrace and balcony inlets

When choosing the right terrace or balcony drain, there are several key factors to consider:

1. Drained area - determines the required capacity of the inlet
2. Type of flooring - influences the selection of the appropriate base
3. Thickness of floor layers - determines the height of the inlet body
4. Water drainage method - vertical or horizontal
5. Insulation requirements - affect collar selection

Our experience shows that it is crucial to precisely define these parameters.   This allows you to select an inlet that is ideally suited to a specific situation. An ill-fitting inlet can lead to drainage problems. In extreme cases, this can result in damage to the building structure.

Many customers ask us about the possibility of combining inlets with other elements of the drainage system. At Onninen, we offer comprehensive solutions. These include not only inlets, but also downpipes and connectors. This makes it possible to create a coherent and effective drainage system.

Practical applications of terrace and balcony drains

Terrace and balcony drains are used in a variety of construction projects. They can be found in both residential and commercial construction.   We recently used the HL inlet system in a project for a large housing estate.   This allowed for effective drainage of several dozen balconies and terraces.

In the case of office reorganization, we most often encounter the need to drain roof terraces. This is where parapet drains come in handy. They allow water to drain at the parapet walls. This is particularly important in the case of flat roofs.

We also often come across questions about inlets for ventilated terraces. In such situations, we recommend two-part inlets. They allow for independent assembly of the body and the cap. Thanks to this, it is possible to precisely adjust to the terrace structure.

Onninen recommends paying special attention to inlets with additional thermal insulation.   They are ideal for use in terraces above heated rooms. They prevent thermal bridges. This translates into better energy efficiency of the building.

In our daily practice, we see how important it is to select the right inlets. The right choice translates into long-term and trouble-free functioning of the drainage system. That is why at Onninen we offer not only products, but also professional advice. Our specialists will help you choose the optimal solutions.
