Anti-oxidant Construction Method
       

The construction method that applies the anti-oxidant solution is called the “Anti-oxidant Construction Method” This method, promoted more than 15 years ago, is currently been used by more than 1,200 contractors in Japan. We have received positive feedback from clients about the power and effects of this construction method. Also the contractors, who are promoting this method, are saying - “We have never been appreciated by our customers this much. It is so enjoyable to construct using this method”.

Since 2003, with the support and effort made by the contractors using the anti-oxidants methods, more and more houses have been built by using the anti-oxidant construction method. They have indicated that these houses are free from the designated 7 harmful chemicals such as aldehydes and VOCs. As the real measures for the sick-house syndrome, the anti-oxidant construction method has been expanding very rapidly.
