"Durability in sandwich panels is its long-term performance as a structural building component. Cladding products have to maintain their strength and insulating properties, and to remain weather resistant over their expected service life. For industrial buildings a lifetime of 25 years can be sufficient but in other cases, requirements can be 50 years or more."
In PAROC panels various primer and coating layers of steel sheets eliminate the potential risk of corrosion inside the panel and ensure the bonding between the adhesive and the steel sheet. To secure colour and gloss retention in the panel surface PVDF is the standard coating in external use. The adhesive is developed to fulfil high durability demands in all environmental conditions during the lifetime of a building. The PAROC structural stone wool is treated to be water-repellent, non-hygroscopic and non-capillary, which means that no water can penetrate. In addition, moisture has no effect on the stability of the core and the binder. |
