Low-Maintenance KMEW Facade Panels

Photocatalytic Coating

Naturally Self-Cleaning - Sunshine Decomposes Dirt, Rain Washes it Away

Self-Cleaning 365 days a year

KMEW’s photocatalytic coating is energized by the presence of light and transforms the coated surface to create a ‘self-cleaning’ functionality. Dirt is decomposed by the sun (UV Rays), and weakening adhesion to the surface and the super-hydrophilic property helps rainwater to wash it away.

Super Hydrophilic Property

When exposed to sunlight, the Titanium Oxide layer breaks down dirt and reduces adherence.

The super-hydrophilic property helps rainwater penetrate under dirt, displaces it, and then washes it away.

Ceramic Coating

20-year Fade Limited Warranty

KMEW’s inorganic ceramic coating has excellent UV blocking properties to protect the color layer from ultraviolet rays and minimize fading of the outer wall. Maintenance costs are reduced by virtually eliminating the need for repainting. This technology is exclusive to KMEW.

There was almost no color change on the KMEW panels. KMEW ceramic coated panels are available in proprietary colors and come with a 20-year color guarantee.

Air Purifying

The photocatalytic coating decomposes car exhaust and other pollutants in the air (NOx and SOx) and turns them into NO3 harmless polyatomic ions leaving the air cleaner.

Plants purify pollutants such as NOx (nitrogen oxides) contained in car exhaust. The poplar tree is one of the plants that absorbs the most NOx.

The air purification capability of photocatalytic coating is appx. 0.44g/day/sq.ft. (0.04g/day/m2), which is 68 poplar trees per 10,000 sq.ft.

Photocatalytic coated exterior surface of a 10,000 sq. ft. building is equal to 68 Poplar trees

The air purifying properties of the photocatalytic coating for a 10,000 sq.ft. building is equal to planting 68 poplar trees. 10 KMEW panels is equal to planting 1 poplar tree.

Resistant to frost damage

Inside the base material there is an 'independent gap' that lets out ice that has frozen and expanded. This prevents the panel from being damaged due to ice expansion.
