External Door and Window Frames
The same door and window frames used in timber-framed construction are also used in steel-framed construction. It is important to advise the supplier of the size of the steel stud supporting the windows and doors.
If aluminium window frames are fitted into timber they can be installed by fastening through the jamb studs into the back of the reveal after positioning.
If it is not possible to secret-fix the frame, as may be the case with a window or door head, countersunk head self-drilling screws of appropriate length can be driven through the frame and packing into the steel framing. The same type of screws may also be used to fasten aluminium window frames direct to steel frame openings.
