A Study on the Enhance of Air tightness Performance of a New Type Silding Window with horizontally Rolling Wheels Jang, Hyok-Soo; Kim, Young-Il; Chuung, Kwang-Seop;
Crevices between window and window frame cause not only heat losses but also serve path to sound transmission and infiltration of fine dusts that are harmful to humans. There were many efforts in the past to eliminate these crevices but because of the windows` indispensable function of opening and closing, it was an unsolvable problem. In this study, a new type sliding window is developed by applying horizontally rolling wheels to implement a surface sealing which is excellent for enhancing air tightness. To evaluate the feasibility of the newly developed window, forces for opening and closing, durability and air tightness were testet according to Korean Testing Standards. Force for opening a 2000 N window is 30 N. It endured 100,000 cycles of opening and closing. Infiltration was for a pressure difference of 10 Pa. Since this window has few moving parts, it has favorable features of low cost and few breakdown.
