VIII
CHESNEY’S DIRECTORY
in THE DIRECTORY, but as shade and striation can
vary substantially, materials will always need to be
inspected and approved.
SELECTION
OF COMPONENTS
Each design is accompanied by a list of those
components from within the range which can
be satisfactorily combined to form a Chimneypiece
of that particular design.
DRAWING
Finally, when the specification process is complete,
a working drawing is prepared for approval.
DIMENSIONS
The size of any Chimneypiece will be governed by the particular combination
of components that are selected and certain architectural rules. Exact dimensions
should always be confirmed with Chesney’s, however
it is possible to follow the simple formulae set out
below as a means of establishing approximate overall
dimensions of each design.
1. Mantel shelf length.
This is calculated by adding together the various
widths of the components that comprise each frieze
and adding a further measurement to take account of
the additional width created by the overhang of the
mantel shelf. It should be noted that where the frieze
panels are not of a fixed size, these should be taken
to be approximately the same size as the centre tablet they accompany, subject
to an increase or decrease of 15% depending on the overall size sought.
2. Overall height.
This is calculated by adding the height of the jamb panel (and where appropriate,
the corner blocks) to a further measurement that takes account of the plinth blocks,
