Sizings
All our window measurements are the frame size only and do not include fins or timber reveals. A window will have a timber reveal surrounding the whole frame, whereas a door will only have a timber reveal on the sides and top of the door.
Each reveal adds 19mm to the frame size of a window or door.
If your window is 1200h x 1210w and fit timber reveals, the window will measure 1238h x 1248w. Whereas, if you have a door that is 2100h x 1810w and fit timber reveals, the door will measure 2119h x 2148w.
To install these, you would need to make sure your stud opening is the correct size. For each reveal fitted, we recommend you add 25mm to the aluminium frame size.
If your window frame is 1200h x 1210w, then your stud opening should be 1250h x 1260w. If your door frame is 2100h x 1810w, then your stud opening should be 2125h x 1860w.
