A double-hung window having a casing with side boards inwardly delimiting sash pockets is replaced by first stripping the casing of the sashes, then filling the sash pockets with fluent particulate insulation, and finally fitting a replacement window into the casing. These holes can be the ones left by removal of the sash-cord pulleys, or can be specially made. The insulation is cellulose and is filled into the pockets by being pumped thereinto. Furthermore on stripping of the sashes same are separated from the respective sash weights which are left in the respective sash pockets.
