The previous owners of my house decided to knock an archway from the rear main wall of the house into the conservatory. Unfortunately, this means that most of my heat disappears out of the conservatory roof and I would like to install double glazed French doors in the gap instead!
The house was built in 1867 and has a timber frame. As far as I can tell the archway does not have an RSJ above it, however, this part of the house does not appear to have any brickwork above ground level with the exterior of the first floor protected by tiles instead!
I've only ever worked on newer houses, and must confess to being a little confused by this! As there appears to be very little brick work above the archway, will an RSJ be needed when installing the French doors?
Many thanks,
Ben
