A sliding door or window frame set consists of sliding panels (1,2) and one fixed panel (3). Rollers (9, 10) are installed at the top of the sliding panels (1,2) to facilitate the sliding movement. Interlockers (13,14) are attached between sliding panels (1,2) and the fixed panel (3) to lock the window. A sub sill (19) is designed to drain water and reduce dampness. Supporting components made of steel or aluminum are installed in some specific positions to strengthen the window or door. |
