Frequently Asked Questions
What exactly are sanitary PVC profiles?
Sanitary PVC profiles — also known as sanitary PVC cove base or PVC cove base systems — are specially shaped rigid PVC elements designed to create smooth, curved transitions between floors, walls, and ceilings in environments that require extreme cleanliness.
Unlike sharp 90-degree corners where dirt, bacteria, and moisture can accumulate, these profiles feature a rounded radius that eliminates hiding spots for contaminants.
The CoRound system, for example, uses food-safe PVC that is chemical-resistant and temperature-stable, making it ideal for cold storage facilities, food processing plants, cleanrooms, and pharmaceutical environments.
Why not just use traditional silicone sealant for corner junctions?
Traditional silicone sealants often crack, discolor, or develop mold over time, requiring frequent maintenance and replacement — which increases costs and downtime.
In contrast, hermetic PVC cove base systems like CoRound Seal feature integrated flexible sealing lips that adapt perfectly to insulated panels or drywall with minimal need of silicone or additional sealants.
This minimal sealant installation creates a permanent, gap-free barrier that prevents infiltration of moisture, dirt, and bacteria while dramatically simplifying daily cleaning and ensuring long-term HACCP compliance.
In which environments are sanitary PVC cove base profiles mandatory or strongly recommended?
Sanitary PVC cove base is essential anywhere strict hygiene standards apply, including food processing plants, commercial kitchens, cold rooms, walk-in freezers, pharmaceutical cleanrooms, hospitals, and laboratories. Regulatory bodies often require HACCP-compliant or FDA-compliant solutions to prevent contamination risks.
These sanitary PVC cove base profiles are particularly recommended for facilities using insulated metal panels, as they maintain thermal integrity, prevent cold bridges, and support easy high-pressure wash-downs.
Do sanitary PVC cove base profiles withstand the extreme temperatures of cold rooms and freezers?
Yes — high-quality food-safe PVC cove base is engineered to perform reliably from -4° F to +140°F (-20°C to +60°C). It resists cracking in freezing conditions, deformation in heat, and degradation from aggressive sanitizers.
This durability makes hermetic PVC cove base the preferred choice for cold storage facilities and food processing environments where temperature fluctuations and daily wash-downs are routine.
Are sanitary PVC cove base profiles truly cleaner than alternative solutions?
Absolutely.
Traditional corners and silicone joints create microscopic gaps that harbor bacteria and mold.
HACCP-compliant PVC cove base eliminates these gaps entirely, providing a fully smooth, non-porous surface that is easy to sanitize and prevents microbial contamination. Certified food-safe and chemical-resistant, these profiles meet the strictest international hygiene standards and are widely preferred.
What’s the difference between a standard baseboard and a sanitary profile like CoR Skirt?
A conventional baseboard is mainly decorative and leaves small gaps where dirt and water can enter.
The CoR Skirt sanitary base is a purpose-designed sanitary PVC base with an integrated upper lip that completely hides fixings and a lower flexible sealing lip that presses against the wall or floor for a perfect hermetic seal.
This creates a seamless, easy-to-clean transition that prevents contamination and is specifically engineered for food-safe and cleanroom applications.
How do these profiles achieve a hermetic seal with minimal sealant use?
The secret lies in the innovative design: sanitary PVC cove base profiles like CoR 4 incorporate soft, flexible sealing lips along the edges.
When installed, these lips compress gently against the surface — even irregular insulated panels — creating an automatic, airtight and watertight seal.
Minimal additional sealant is needed, resulting in faster installation, lower labor costs, and a completely smooth, non-porous surface that resists bacterial growth and chemical cleaning agents.
Is installation complicated? Do I need a specialized technician?
Installation of sanitary PVC cove base systems is actually much simpler and faster than traditional silicone methods.
Profiles like CoR 4 are placed onto a pre-drilled support (CoR Base), fixed with hidden screws, and completed with snap-in accessories (corners, joints, end caps).
Most installers of insulated panels or drywall can complete the job quickly without specialist training, saving significant time and money compared to messy sealant applications.
Do I need to purchase special accessory pieces for corners and junctions?
Yes, and that’s one of the strengths of a complete system like CoRound.
In addition to the main sanitary PVC cove base profiles, you’ll use dedicated accessories — such as 2-way and 3-way internal/external corners, straight joints, end caps, and termination profiles — all featuring the same flexible sealing lips.
This ensures every transition remains perfectly hermetic and seamless, eliminating any weak points in high-hygiene installations.
How long do sanitary PVC cove base profiles last, and what are the long-term maintenance costs?
Premium sanitary PVC cove base profiles are built to last decades without degradation, thanks to their robust, UV-stable, and chemical-resistant PVC construction.
Maintenance is virtually zero: just routine cleaning with standard detergents. While the initial investment may be slightly higher than basic silicone, the savings in labor, downtime, and replacement costs quickly outweigh it, delivering excellent ROI for cold storage, food processing, and cleanroom facilities.
