no just use normal 2 1/2 or 3 x 8 or 10 screws that have a good thread,make sure screws arn't to long or will come through,and screw window to door or you will see screws every time you open door. before you screw together use silicone to seal or you will get a draught,there should be some ribs on the side of window that usualy goes to the brickwork,put some silicone down these then screw together.hope this helps
