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.

A sustainable renovation of an older building involves much more than installing a new heating system or improving insulation. Windows and doors must once again provide reliable sealing. This is exactly where the poesia group comes in. The company offers a vast range of more than 5,000 replacement seals and profiles. These seals are suitable for windows made of wood, PVC, metal, or wood-aluminium combinations. They are also ideal for wooden doors, door frames, flush doors, shower cabins, refrigerators, and freezers.

Sample Service

But which seal is actually the right one? To answer this question, the poesia group offers its practical sample service. Customers can either send in an old seal or a photograph of it. The specialists then identify the appropriate replacement seal and provide a free sample. This allows customers to verify the fit before placing an order.

If a completely new seal is required, the consulting service includes a comprehensive solution—from the initial concept sketch to the production of the ready-to-install sealing profile. New TPE and silicone seals can be manufactured from as little as 300 metres. Many customers particularly appreciate this comprehensive service.

Broad Customer Base

Customers who rely on the seals provided by the poesia group include carpenters, metal fabricators, window manufacturers, renovation service companies, sanitary contractors, and refrigeration technicians. Naturally, private customers are also welcome.

Online Shop

If all specifications for the required seal are already available, orders can be placed directly through the online shop at https://shop.mk-dichtungen.ch , by telephone or by email.

Easy Installation

Seals are supplied either by the metre or as fully customised products. They are cut precisely to the required dimensions and can be glued, welded, or vulcanised, significantly simplifying installation. Accurate measurements are therefore essential when placing an order.
