Seals

The function-specific interaction between hardware and seals directly influences the performance of the building elements with regard to operating convenience, energy efficiency and sound insulation.

Roto offers the perfect hardware, seal and glazing technology to match your window and door systems. And this is regardless of whether you make these from PVC, timber or aluminium. That’s not all – the range of services available is unparalleled. So we can say for certain: Roto – it’s the #perfectmatch for you.

Roto subsidiaries Deventer and Ultrafab are able to offer you sealing profiles for different systems and requirements. They process various synthetic materials for an almost unlimited range of applications. When it comes to these two companies’ product range and marketing coverage – they are a #perfectmatch!

An internationally very successful example of use which demonstrates the benefits of integrated product development is the tightly sealed Roto Patio Inowa sliding system: the special design of the hardware and the circumferential seal between the sash and frame profile represent a real revolution in sliding elements.

Seals are all too often underestimated. But they play a pivotal role in window and door systems: they not only ensure that the building elements are tightly sealed, but also make them durable and user-friendly. This is important because for end users, who often have limited technical knowledge, it is usually the ease of use of windows and doors alone which determines their impression of quality.

Requirements for the energy efficiency of buildings are growing as extreme weather events are becoming more frequent. Tightly sealed, soundproofed windows and doors are therefore becoming increasingly important for environmental protection, security and comfort.

Deventer and Ultrafab seals are able to meet the most stringent demands for many different types of windows and doors made from timber, PVC and aluminium frame materials.

Deventer and Ultrafab manufacture their products at a total of seven sites and deliver consistently high-quality seals on time and in large quantities. The seals are designed and tested to customer specifications.

As technological leaders, both companies offer support to customers at an early stage of their product development. Consultation is necessary if a special window or door design is to be developed or manufacturing processes need to be made more efficient. Prototypes of a new sealing profile are created at short notice.

Production takes place on consumption-optimised, modern plants. Up to 99% of production residues are prepared and recycled. The use of regeneratively produced power is also being systematically promoted.

Seal materials

Deventer and Ultrafab develop customer-specific sealing profiles from the synthetic materials that offer the ideal material properties for the desired solution. These companies offer a huge variety of seals, ensuring that all windows and doors worldwide can be equipped with compatible seals.

• Deventer processes: thermoplastic elastomer, flexible PVC, silicone rubber
• Ultrafab processes: thermoplastic elastomer, rigid PVC, flexible PVC, polyamide, hot-melt PVC, polyolefins

If they need particularly effective seals, companies outside the building elements industry also turn to our experienced specialists due to their comprehensive expertise in the processing of synthetic materials.
