In Edinburgh the FMB took to the stage at the Edinburgh Traditional Building Festival this August. Taking place just off the Royal Mile and part of the world famous Edinburgh Festival Fringe, this festival had practical demonstrations on maintaining and repairing traditional buildings. All the shows and demonstrations were free and aimed at the public.
The organisers: the Edinburgh Traditional Building Forum were eager to involve the FMB. With thanks to member HM Raitt & Sons Ltd who took up the opportunity:

Sash and case windows have two glazed, timber-framed components: the sashes, which slide up and down, and the case, in whose channels they sit. The channels of the case are formed by the case itself and by two strips of timber called the baton rod and the parting bead.
These type of windows are often seen in traditional properties including tenement flats which comprise around one quarter of all occupied dwellings in Scotland according to the 2019 Scottish House Condition survey.
