This study relates the historical development of fenestration in Irish buildings (mostly
those of the classical tradition), using buildings or windows characteristic of each definable
architectural period (chosen from published sources or site work). It shows that there is a close
relationship between window design and the Irish interpretation of the classical idiom, and that
change in the period under review came about from a fusion of aesthetic ideals and ongoing
technological development. Because of the aesthetic and practical importance of the constituent
elements in the window, a detailed mention is made of the types of glass and framing materials
used. The history of window -glassmaking in Ireland is also chronicled. The details and elements
of the windows used during this period - types of glazing, shaped windows, and openings,
frames and lights - are examined (referring back to the important windows introduced in the
historical account) to underline the variety found at every period.The foregoing analysis establishes the importance of fenestration in Irish architecture,
especially that of the classical style. Irish developments are then set within the North European
classical architectural context, in which fenestration has long been recognised as a fundamental
design tool. The research carried out brings to light the high standards of design and
workmanship achieved in Ireland, underpinning the argument for conservation. The philosophy
and practicalities of conservative repair are discussed in an inquiry into the requirements for
window conservation, expanded upon by reference to case histories and discussion of
educational and financial matters.A glossary of terms is given and five appendices complement the text. Two inventories
present the physical evidence and documentation used in this research, listing the relevant
details of the key buildings and the window- glasshouses. There is an essay on the glazing
fraternity, and some information is given on Irish window joiners and carpenters. The final
appendix defines some of the more commonly used conservation terms
