Insulation of Ventilation Ducts (De Groeiboom)

The customer
De Groeiboom is a primary school in Ostend, offering both kindergarten and elementary education. The school also includes a daycare center.
Purpose
Following storm damage, CGK was responsible for restoring the insulation on the ventilation system used to air classrooms at De Groeiboom primary school.
Problem-solution
Due to harsh weather and strong winds, part of the insulation panels around the roof-mounted ventilation system was blown away and damaged.
Our project manager and insulation expert assessed the damage on-site. Initially, a budget-friendly repair was planned to restore the insulation as much as possible.
However, once work began, it became clear that the storm damage was more extensive than expected. In consultation with the client, we decided to fully reinsulate the damaged section rather than patch it up.
- The installation was insulated with stone wool lamella mats and covered with aluminum insulation panels. Next, all seams were sealed watertight with specialized silicone.
- The cladding serves as protection against rain, cold, wind, and other external influences. To prevent the cladding from blowing away again, we added extra support to the insulated ventilation ducts.
- Since the ventilation ducts enter the building through the roof, they also conduct cold air inside. That is why the ducts need to be well insulated. This way, we prevent room cooling and reduce energy loss.
We are proud of our CGK team, who braved the strong coastal winds and completed the job within a week!
