Roof drains and accessories - comprehensive solutions for rainwater management

Effective drainage of rainwater is a key aspect of any roof structure. At Onninen, we offer a wide range of roof outlets and accessories. Our products ensure effective management of rainwater. We care about the safety and durability of buildings. We provide solutions tailored to various needs.

Gravity roof drains are the basic elements of a drainage system. They use natural forces to drain water. They work well in many standard installations. Heated roof drains are an ideal solution for regions with low temperatures. They prevent freezing and blocking of the drain.

Variety of roof outlets - selection to suit the specifics of the project

Our offer includes flat roof drains. They are designed for roofs with a minimal slope. Roof drain extension elements allow for height adjustment. Drainage rings increase system capacity. Control and drainage attachments facilitate inspection and maintenance.

Each project requires an individual approach to rainwater management. That is why we offer roof drains made of various materials. Plastic drains are lightweight and corrosion-resistant. PEHD drains are highly durable. Models with a connecting flange provide a tight connection with insulation.

• Roof drains with vapor barrier - ideal for insulated roofs
• PEHD connection sockets - for a durable and tight connection
• Fixing collars - stable installation of the inlet in the roof structure
• Emergency transfers - additional protection against flooding

We often come across the question of choosing the right size of the inlet. Roof connections DN90 and DN110 are the most popular sizes. The choice depends on the roof area and the intensity of rainfall. Our experts will be happy to advise on the selection of the optimal solution.

Premium brands in the category Roof drains and accessories - rainwater management

At Onninen, we rely on proven brands. Geberit, HL and Kessel are leaders in the drainage industry. Their products are characterized by the highest quality and reliability. Our experience shows that investing in renowned brands is a guarantee of long-term use.

Geberit offers innovative solutions for different types of roofs. HL specializes in flat roof systems. Kessel supplies advanced drains with additional flood protection. Each of these brands has its own specialization. This allows us to match the product to the specific requirements of the project.

We recently used the Geberit system for a large shopping centre project. The requirements were very specific. The large roof area and local regulations required exceptional performance. The heated Geberit drains proved to be excellent. They ensured reliable drainage even in winter.

Practical aspects of selecting roof drains and accessories

Choosing the right drainage system is a key decision. It affects the safety and durability of the entire building. At Onninen, we advise on how to select drains and accessories for a specific application. We take into account the type of roof, its surface and local climatic conditions.

Roof inlet grilles are an important element of the system. They prevent dirt from entering the system. The selection of the appropriate grille depends on the specifics of the roof. For gravel roofs, grilles with larger holes are used. Green roofs require special filtering solutions.

1. Roof Surface and Local Rainfall Analysis
2. Selecting the type of inlet (gravity, heated, flat)
3. Material selection (plastic, PEHD, metal)
4. Determining required bandwidth
5. Selecting the right accessories

When reorganizing drainage systems, we most often encounter the challenge of integrating new elements. Our experience shows that compatibility is key. We offer a wide range of extensions and adapters. They enable the connection of different systems and brands.

Many customers ask us about solutions for roofs with unusual shapes. In such situations, inlets with an adjustable angle are useful. They allow for precise adjustment to the geometry of the roof. This is especially important in modernization projects.

Managing rainwater is not just about draining it. We are increasingly faced with the need to store and reuse it. We offer systems that allow for the collection of rainwater. It can then be used for irrigation or economic purposes.

Our experience shows that proper installation is as important as product selection. That is why we offer training and technical support. Our experts provide advice at every stage of implementation. We ensure that the system will operate effectively for years.

Onninen recommends regular inspections and maintenance of drainage systems. Prevention prevents serious failures. We offer comprehensive service solutions. These include cleaning, replacement of seals and checking for obstruction.

In everyday practice, we see how important the flexibility of the system is. Weather conditions are becoming more and more unpredictable. That is why we recommend modular solutions. They allow for easy expansion or modification of the system in the future.

Roof drains and accessories are key elements of building safety. Their role is often underestimated. A properly selected and installed system prevents flooding. It protects the structure from water damage. It is an investment that pays off in the form of peace and security.
