At the upcoming Polyclose trade fair in Ghent, Deventer Profielen and Roto will be presenting themselves jointly at a single stand. Not just as two partners, but as the ‘perfect match’ in fittings and seals. Deventer Profielen from Breda, as a member of the ROTO Group, is part of a powerful network that combines expertise in hinges and locks with high-quality sealing specialism. Both companies retain their own identity, but emphatically reinforce each other. Deventer supplies the seals, Roto the fittings; together they create integrated facade solutions that demonstrably perform better and contribute to sustainable, comfortable living.
Nowadays, a comfortable home must meet many requirements. It must be airtight, energy efficient, prevent moisture problems, and meet the highest soundproofing standards. The sealing profiles from Deventer Profielen in Breda play a crucial role in this. Deventer develops and manufactures a complete range of seals for facade elements—both standard and custom—that ensure windows and doors function sustainably, reliably, and comfortably.


“A home with window and door frames fitted with Deventer sealing profiles meets all the requirements and wishes of users and installers in terms of quality, durability, and application,” says commercial manager Jean-Paul Batenburg. “They guarantee optimal ease of use and living comfort.”
According to Batenburg, air quality is a particularly important factor in living comfort. “Good sealing prevents draughts and, together with ventilation, ensures a pleasant level of humidity, which contributes to a healthy indoor climate. Thanks to close cooperation with Roto, these sealing profiles also fit perfectly with the hinges and locks, further enhancing the performance of the entire system.”
The combination of Deventer seals with Roto's technical hardware solutions results in façade elements in which all components work together optimally. Roto contributes its expertise in smooth, intuitive, and reliable locking technology, while Deventer provides seals that keep out wind, water, and noise. Integrating both areas of expertise from the design phase onwards creates a fully coordinated total solution.
This integration is evident in the ease of use, visible in the performance, and noticeable during installation. Profiles from Deventer are designed with a high tolerance capacity, making them easy to process and ensuring reliable functioning in combination with Roto's adjustable hinges and locks.
Deventer Profielen has been building a solid reputation as a specialist in the window frame industry for decades. The profile design is unique, with a high capacity to accommodate tolerances in wood, plastic, and aluminum. This experience is underlined by various ISO and IFT certifications and the KOMO quality mark for a large number of profiles.
Deventer profiles have also been extensively tested for airtightness in accordance with Dutch and European standards. Various seals are classified for class 3 airtight construction and comply with the most stringent class 4 of NEN-EN 12207. In this way, Deventer and Roto together contribute to high-quality, energy-efficient, and future-proof facade constructions.
Deventer Profiles distinguishes itself not only in design and quality, but also in sustainability. The profiles are made from TPE, free of chemical components, fully reusable, and produced in an environmentally friendly manner. Deventer was the first manufacturer worldwide of sealing profiles with Cradle to Cradle Silver certification.
This high level of sustainability fits perfectly with the ROTO Group's forward-looking vision. What's more, Deventer is one of the initiators of the C2C Construction Group, which further underlines their position as an environmentally conscious specialist.
