Since 22 July 2026, our SAGLAN Production Production at Dürrenäsch is temporarily suspended. We are using this planned production stoppage, which will last until 9 August, to carry out extensive maintenance work on our plant. Over the past few days, our specialists from various departments have inspected numerous plant components, replaced wear parts and checked mechanical and electrical systems. Further work and final tests will follow in the run-up to the planned restart. The shutdown is not an unplanned outage. It was planned well in advance and forms an integral part of our production operations. Certain tasks can only be carried out when the plant is completely shut down.

Targeted work rather than replacement on a whim

A production plant consists of numerous mechanical, electrical and digital components. These are subjected to varying degrees of wear and tear during day-to-day operation. It is therefore important to assess their condition regularly and to plan any necessary maintenance work in a targeted manner.

During the current audit, the following, amongst other things, will be carried out:

• Wear parts replaced
• safety-critical components are inspected
• checked the measurement and control systems
• mechanical systems tested
• electrical systems inspected and repaired

We do not replace as many components as possible as a precautionary measure. What matters is the actual condition of the component in question.

Components that are still in working order remain in service. Components that have reached a defined wear limit are repaired or replaced. In this way, we focus our available resources on the work necessary to ensure the safe and stable operation of SAGLAN’s production facilities.

Digital condition data supports planning

Our digitised plant infrastructure continuously provides maintenance and condition data. This data is recorded and analysed centrally. This enables our specialists to identify at an early stage which components are under greater strain and where action may be required. We explain in detail exactly how we apply this in our production process in our article ‘Predictive maintenance at SAGER“, where we also look at the technologies used go into.

The current maintenance work was also planned on this basis. The necessary spare parts could be procured in advance, specialists scheduled, and individual work stages coordinated with one another.

This condition-based maintenance prevents unnecessary interventions. At the same time, it allows the available time to be focused on those tasks that are technically necessary. This also enables the duration of production downtime to be planned effectively.

Many departments work together

Since maintenance work began on 22 July, numerous tasks have been carried out in coordination with one another. Staff from production, maintenance and other specialist departments are carrying out clearly defined tasks.

Mechanical work must, for example, be co-ordinated with electrical tests and checks on the measurement and control systems. Individual work stages cannot begin until the preceding work has been completed.

Planning therefore began well before the actual production shutdown. Responsibilities, materials and timelines were organised in such a way that the overhaul could be carried out within the scheduled timeframe.

Preparations are being made for the restart

The outstanding maintenance work will be completed by 9 August and the affected systems will be checked. We will then gradually resume SAGLAN production.

Before regular production begins, the specialists involved check the work that has been carried out. Mechanical, electrical and safety-related components are tested.

Production will only resume once all systems are operating reliably. This controlled restart helps to ensure that production processes run smoothly right from the start.

A direct impact on SAGLAN quality

SAGLAN is our glass wool, produced in Dürrenäsch, for thermal, acoustic and fire insulation. The condition of our production facilities has a direct impact on its manufacture.

Stable production processes are essential for ensuring consistent product characteristics and a consistently high standard of quality. Regular maintenance work also reduces the risk of unplanned downtime.

For our customers, this means greater reliability in terms of the quality, availability and delivery of SAGLAN products.

The current production shutdown is therefore not merely intended to maintain the equipment. It is also an important part of our quality assurance process and lays the foundations for a production operation that remains efficient in the long term.

Conclusion

From 22 July to 9 August 2026, our SAGLAN production line will be shut down for scheduled maintenance work. During this period, our specialists will inspect the relevant parts of the plant, replace worn components and carefully prepare the systems for restart.

Digital maintenance and condition data enable us to plan our work in a targeted manner and intervene only where technically necessary. In this way, we ensure that our SAGLAN production system operates safely, stably and reliably once the overhaul is complete.
