When planning the renovation of an older building, most people first think of a new heating system, improved roof and façade insulation, or renovating bathrooms and kitchens. However, one crucial aspect is often overlooked: old and worn seals in windows and doors.

Many houses built in the 1960s and 1970s no longer meet today’s energy-efficiency standards, and poorly insulated buildings lose a significant amount of valuable heat. The consequences include excessively high heating costs, drafts, moisture, and mould growth. In addition, the indoor climate becomes uncomfortable, as rooms are often too hot in summer and too cold in winter.

From window seals and doors to industrial systems: seals ensure tightness, protection against environmental influences and energy efficiency. Despite their important function, they often go unnoticed.

This is exactly where Rubby comes in. The mascot of the poesia gruppe makes the world of seals, materials and applications easy to understand.

Mit grosser Trauer nehmen wir Abschied von Hans Beat Christen, der am 8. April 2026 verstorben ist.

Hans Beat Christen war weit mehr als ein langjähriger Mitarbeiter – er war Mitgründer, Verwaltungsratsmitglied, Wegbereiter und eine prägende Persönlichkeit der heutigen poesia-gruppe. Als Mitgründer der pbc polymer ag hat er mit grosser Leidenschaft, unternehmerischem Weitblick und unermüdlichem Engagement den Grundstein für unseren heutigen Erfolg gelegt.

For many years, poesia-gruppe, based in Unterkulm, has been investing successfully in the future by training apprentices. It offers various apprenticeship programmes and thus provides young people with a promising entry into professional life.

Timo Steiner, first year commercial employee EFZ apprentice, found his first weeks of apprenticeship very pleasant. By now, he is very familiar with various tasks. He appreciates the good exchange within the team, which leads to joint solutions. Thanks to good organisation between work, school, studying and hobbies, he has found a healthy balance to manage everything successfully.

Swiss Plastics Expo will take place from 20 to 22 January 2026 at Messe Luzern. It is the trade fair and symposium for everyone working with plastics. The poesia-gruppe will present its sealing solutions at its own stand and will also appear as a manufacturer of high-quality sealing solutions.

The trade fair is aimed at experts from a wide range of plastic application fields: from industry and mechanical engineering to construction, gastronomy and medical technology. This unique industry event offers opportunities for inspiration, further education and networking.
