Our aluminum clad windows and doors were manufactured in Denmark so the fitting of them to the log house is down to us to sort out. So we took the smallest window in the house and made a trial set of linings.
Then we routered the outside of the log “D” profile to create a flat surface for the external architrave to sit in.
Then we made a header with the same angle on the ends as the log dovetails so that it looked in keeping with the logs.
We are going to look at this for a week or so to make sure we are happy with the look before maching all the other window and door linings.
