Cool in summer, warm in winter, always comfortable! A new pumice block in harmony with nature.
"Super Light Stone" is a lightweight block made from pumice that is produced when extracting sea sand from Kinko Bay in Kagoshima Prefecture. Using a special solidifying agent called "YHR liquid," this pumice is solidified to create a lightweight block that is strong, has excellent permeability, does not retain heat, and is easy to process. It is an eco-friendly, future-oriented super block that utilizes pumice sourced from the naturally rich sea of Kinko Bay for sustainable urban development. 【Features】 ○ Permeability (does not splash water) ○ Water retention (reduces the heat island effect) ○ Special medium (blocks with excellent strength) ○ Environmental material (enhances landscape) ○ Cost reduction (effective use of pumice) For more details, please contact us or download the catalog.
