Legerair Panel Projects
Legerair Coating
We added anti-moss protection, preventing moss from adhering to the surface, on top of the standard Photocatalytic Ceramic Coating that uses the sun's light to break down and eliminate dirt.
1. Dirt is broken down by the sun and washed off by rain
Thanks to light from the sun, dirt adhering to the external walls' surface is broken down.
Then when rain falls, the water seeps beneath the dirt and then rises back up, breaking it off and washing it away.
The photocatalytic walls perform self-cleaning 365 days a year, so even 10 years down the line they will still be sparkling clean.
2. Resistant to fading
The ceramic coating thoroughly protects against UV rays.
Because it uses inorganic paint that is resistant to deterioration, it remains effective over a long period of time.
3. We added an "anti-moss effect" that prevents the adhesion of moss
The Photocatalytic Ceramic Coating (+ moss protection) used in Legerair contains copper, which has a long-lasting anti-moss effect, and maintains this effect for a long time.
Conventional Photocatalytic Ceramic Coating
The decomposition power of titanium oxide (TiO2) suppresses the growth of moss.
The Photocatalytic Ceramic Coating (+ moss protection) used in Legerair
The titanium oxide (TiO2) further improves the anti-bacterial strength of the copper (Cu), allowing the decomposition power to suppress the growth of moss.
A KMEW Experiment: Measuring Moss Death Rate
We shine UV rays onto the surface and confirm the survival/death of the moss.
As a means of doing this, the (green) moss that are not dyed in the methylene blue solution are measured as alive, and the (blue) moss that are dyed are measured as being in a dead state.
Legerair Base Material
Deep texture, light
Experience a new design with an unprecedented depth.
Despite its 21-mm thickness, it is surprisingly light!
Resistant to frost damage
Inside the base material is an "independent gap" that lets out ice that has frozen and expanded. This prevents the panel from being damages due to ice expansion.
