Because unplasticized PVC is harder and less flexible than standard PVC, it is used to manufacture double-glazed and standard window frames. However, many manufacturers void their product warranty if you drill the material before attaching it to the blinds. To overcome this problem, some blind manufacturers have developed a mounting frame that clips onto the window without using screws. Alternatively, you can attach blinds away from the uPVC window frame above the window opening on the inside wall.
