New Hospital Flooring Free of PVC - an Alternative?

• PVC to be phased out…
• Risk of toxic smoke when PVC burns…
• Plasticizers considered a health risk…
• Adhesives may react with floors and create cross reactions…
….but many facilities are used to this floor?
…Why should they change?
Looking for an Alternative to PVC?

• Is it a risk to go for a new product in a hospital?
• Just environmentally ok, but what about the practice?
• Cleaning and hygiene are vital for a hospital. How does a sustainable product behave?
• Could it be a cost trap?
Cleaning of Hospital Floors - A Cost Trap?
4
• Over a life time of 15 years cleaning and maintenance costs of the floors make about 80 - 90 % of the total costs of the floor
• Regular cleaning alone only makes 50% of these costs • The remaining costs are made up by costs for
• coatings • repair of surface protections (PU etc.) • downtime costs
