The birth of "additive-free housing" that is committed to natural materials to the extreme, using no chemical substances: rice glue, animal glue, and plaster...
Most of the causes of sick house syndrome are chemicals contained in adhesives. For many years, we have researched whether it is possible to build houses without using any chemical adhesives. Finally, we have completed a house that is additive-free and good for the body. We carefully select natural materials for building materials and achieve the ultimate in additive-free construction. For example, we use "rice glue," made from rice, as an alternative to chemical adhesives, and "nikawa," made from animal bones and skins. As a result of years of research, we have been able to produce harmless natural glue consistently and utilize it in fixtures, making it practical. Additionally, we have developed an inexpensive "lime plaster" application method as an interior material to replace problematic vinyl wallpaper, avoiding harmful substances and advancing home building with additive-free materials and methods. 【Features】 ■ Commitment to natural materials to the utmost limit ■ Additive-free materials and methods - Adhesives → "Rice glue" made from rice → "Nikawa" made from animal bones and skins - Lime plaster → For exterior walls, interior walls, and ceilings * For more details, please contact us or download the catalog. * We are currently recruiting nationwide agents!
