What exactly are hygienic PVC profiles?

Hygienic PVC profiles — also known as sanitary PVC coving or PVC coving 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 (typically 4 inches) 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 coving systems like CoRound Seal feature integrated flexible sealing lips that adapt perfectly to insulated panels or drywall without any silicone or additional sealants.

T|his sealant-free 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 hygienic PVC profiles mandatory or strongly recommended?

Hygienic PVC coving 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-approved solutions to prevent contamination risks.

These sanitary PVC profiles are particularly recommended for facilities using insulated sandwich panels, as they maintain thermal integrity, prevent cold bridges, and support easy high-pressure wash-downs.

Do hygienic PVC profiles withstand the extreme temperatures of cold rooms and freezers?

Yes — high-quality food-safe PVC coving is engineered to perform reliably from -15°C to +60°C (and often beyond). It resists cracking in freezing conditions, deformation in heat, and degradation from aggressive sanitizers.

This durability makes hermetic PVC coving the preferred choice for cold storage facilities and food processing environments where temperature fluctuations and daily wash-downs are routine.

Are hygienic PVC profiles truly more hygienic than alternative solutions?

Absolutely.

Traditional corners and silicone joints create microscopic gaps that harbor bacteria and mold.

HACCP-compliant PVC coving 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 preferre

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 skirting is a purpose-designed hygienic PVC skirting board 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 without silicone?

The secret lies in the innovative design: hygienic PVC coving 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.

No 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 coving 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 hygienic PVC coving 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 hygienic PVC profiles last, and what are the long-term maintenance costs?

Premium sanitary PVC 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.
