Stirling SCOTLAND -- Burlington Slate announced its association with the third phase of restoration of Stirling Castle. Burlington's roofing slate was specified to provide a match for the original local Aberfoyle slate roofing material. Used on the roof of James IV's medieval Great Hall as well as the roof of the two turrets, a Fa'doon and a Pentis roof for an open arcade that runs most of the length of the west elevation of the Hall, Burlington's natural slate was laid in random widths (18 inches reducing to 9 inches long) and in diminishing courses. It was also center-fixed with stainless steel screws and double screwed every fourth course through one layer of Tyvek membrane into oak sarking. The slate roof was complemented by Catcastle stone specified to match the existing, with an exterior limewashed with nine coats of pigmented limewash. "We are delighted that our natural roofing slate has been specified for the restoration of one of the world's most famous castles. Burlington has a long association with buildings of architectural and historical importance, and Stirling Castle is no exception," stated Malcolm Hatch, Burlington Slate's managing director. Main contractors for the project were West Lothian-based Barry D. Trentham Ltd.
