Sandwich panels are casted with or without ventilation grooves. The porous stone wool insulation helps the concrete sandwich panels dry quickly, meaning decoration work can be started earlier.
A) Without ventilation

- Supporting structure: concrete inner leaf
- Thermal insulation PAROC COS 5, (PAROC COS 10, PAROC COS 15) according to loading requirements + stainless steel trusses cc 600 mm
- Concrete outer leaf
- Surface finishing

B) With ventilation grooves
The open structure of stone wool enables the whole external wall structure to dry out fast. Ensure the drying is completed by using insulation slabs with vertical ventilation grooves. The grooved insulation improves the drying of the structure and reduces the arching of the outer leaf. Make the drying even more effective by using insulation with both vertical and horizontal grooves.
