Installing a window frame

This morning we learned the a way to install a timber window frame and clad all around it. First we covered the frame in brown paper which represents sistalation.We then packed the frame out until it was sitting flush with the cladding. the next thing we did was put the flashings on, making sure that it overlapped in a way so no water can get in the walls. Once we had cladded around it,we cut the nosing to fit and then finished it off by cutting architrave to go around the outside.Before that we went through a work book called install and replace windows which also had good information on common brick types and hinge types.
