"We used to turn the TV volume up very high so we can hear it" says the K family living in the suburb of Hamamatus City, Shizuoka prefecture, Japan. Their house is on a busy street with high speeds. Also, there is a Heavy Equipment and Truck Rental Company across the street from their house, making loud noise, such as engine sound. It was GAINA that solved the K family's trouble. Coating GAINA on all the exterior walls of their house greatly reduced the noise pollution. Even in the living room that faces the busy street, they are able to watch TV set at a normal volume level. "Now we hear voices that we couldn't hear before in the noise, and enjoying our family conversations" says Mr. K with a smile.


The room is so quiet, they don't notice the sound of rain.

O family in Kanazawa prefecture chose GAINA because every year their children complained that "Our room on the 2nd floor is so hot." After Coating GAINA, not only did the temperature drop significantly, but also they noticed less noise. "Sometimes we have to hurry to get our laundry from outside because we don't notice the sudden shower" says Mr. O.

T family in Suka city, Saitama prefecture had trouble with noise because their house is in a noisy shopping district, and there is a lot of traffic. "After we painted GAINA, we realized how quiet it is in the house. We don't even notice the noisy cars and people that we used to hate" says satisfied T family.
