Roof drains - rainwater management: the key to effective building protection

Effective drainage of rainwater from roofs is the basis for the protection of buildings. At Onninen, we offer comprehensive solutions in this area. Our wide range of roof outlets ensures reliable management of rainwater. These products protect structures from moisture and damage. Selecting the right system is crucial for the durability of the building.

Our offer includes roof drains from renowned brands. These include Geberit, HL and Kessel. Each of them is famous for the high quality and reliability of their products. Thanks to this, you can be sure of long-term and trouble-free use.

Types of roof inlets - how to choose the optimal solution?

In practice, we meet the diverse needs of our customers. That is why we offer a wide selection of roof drains. These include:

• Gravity roof drains
• Heated roof drains
• Flat roof drains
• Plastic roof drains
• Inlets with connecting flange
• Inlets with vapor barrier
• Inlets with protective grid

The selection of the appropriate type of inlet depends on many factors. The key factors are the roof parameters, its slope and the expected load of rainwater. Gravity inlets work well on roofs with a greater slope. For flat roofs, we recommend heated models that prevent freezing.

Plastic inlets are an economical solution for smaller objects. In the case of roofs with a membrane, inlets with a connecting collar are necessary. They provide a tight connection with the insulation. Models with a vapor barrier protect against condensation of water vapor under the roofing.

Roof drains - rainwater management in practice

In everyday practice, we observe how key a role roof drains play. Properly selected and installed, they ensure effective water drainage. We recently completed a project for a large shopping center. We used a Geberit heated drain system there.

This solution ensured reliable operation even in winter. It eliminated the risk of snow and ice accumulating on the roof. This prevented overloading of the structure and potential leaks. The system proved to be excellent, confirming the high quality of the products we offer.

In the case of modernization of older buildings, we often recommend inlets with a protective grid. They protect against dirt that could block the drain. This is especially important in the vicinity of trees and in the autumn. This solution significantly reduces the need for frequent cleaning of the system.

Roof drains are not only a technical element, but also an aesthetic one. In modern architectural designs, we often use flat drains. They harmoniously blend in with minimalist design. At the same time, they provide high water drainage efficiency.

Innovations in rainwater management - inlets of the future

The roof drain industry is constantly developing. New, advanced solutions are emerging. We are increasingly encountering inquiries about intelligent systems. Inlets equipped with sensors can monitor water flow. They inform about possible blockages or system overloads.

Another trend is the use of rainwater. Modern inlets can be part of the rainwater collection and filtration system. Such solutions are gaining popularity in the context of sustainable construction. They allow for significant savings in drinking water consumption.

At Onninen, we follow these trends and are constantly expanding our offer. We work with leading manufacturers to deliver state-of-the-art solutions. Our specialists will be happy to advise you on selecting the optimal system for each project.

It is worth emphasizing that the right choice of roof drains is a long-term investment. It translates into the safety and durability of the entire building. That is why we always recommend consulting an expert before making a decision.
