The uPVC casement windows we make here at Quickslide are made using a sculptured profile called Heritage 2800 from our partnering extruder Deceuninck. All our windows are made to order and based on the sizes and specification supplied by you we will manufacture your new windows from start to finish at our manufacturing facility in Brighouse. First step in the manufacturing process is cutting the uPVC profile to the right frame sizes. The uPVC is then welded together to create the window shape. The process is then followed by glazing and final assembly.
