The Stained Glass Windows in the Sanctuary of St. Peter’s Church are the work of two major English studios - Heaton, Butler, & Bayne, and the studio of Charles Eamer Kempe, and were completed at various times between 1909 and 1934. The windows in the Lady Chapel were completed by Chapman Stained Glass Studios of Albany in 1983. 

Windows by Heaton, Butler, & Bayne can be seen in scores of churches throughout England and Wales, most notably at Westminster Abbey and Chester Cathedral; in many notable churches in the United States including Calvary Episcopal Church in Pittsburgh, St. Alban's Church in Philadelphia, and St. Matthew's Cathedral in Laramie, Wyoming; and in other countries as well including the Cathedral of the Holy Trinity in Quebec City, Canada, and St Andrew’s Cathedral in Sydney, Australia. 

Windows by the Kempe firm can be seen in many notable Anglican churches – including Chester Cathedral, Winchester Cathedral and York Minster Cathedral in England; and the Church of the Advent in Boston, Christ Church in New Haven, the Church of the Incarnation in Manhattan, and St Mark's Church in Philadelphia in the United States.
