caption_attribution_description: Old St. Paul's is a former cathedral in the Diocese of Wellington of the Anglican Church in Aotearoa, New Zealand and Polynesia. It is an example of 19th-century Gothic Revival architecture adapted to colonial conditions and materials. It is at 34 Mulgrave Street, Thorndon, Wellington, New Zealand, close to the New Zealand Parliament. Old St. Paul's was designed by Reverend Frederick Thatcher, then vicar of St. Paul's, Thorndon. The foundation stone was laid by Sir George Grey in August 1865. The church was consecrated by Bishop Abraham on Trinity Sunday, the 27th of May, 1866. It is constructed entirely from New Zealand native timbers, with stunning stained glass windows. The interior has been likened to the upturned hull of an Elizabethan galleon - exposed curving trusses and kauri roof sarking.
context_page_description: Sarking is an English word with multiple meanings in roof construction:
  The use of wood panels, or "sarking boards", called sheathing, sheeting or decking in American English, under the roof-covering materials such as the shingles of a roof to provide support. It is a common term in Scotland, Australia, and New Zealand. The shingles or slates are nailed directly to the sarking boards without timber battens, providing a strong, wind-resistant roof.
  An additional layer within a roof that insulates or reflects heat, such as a layer of felt, reflective foil, or polystyrene.
  Roofing felt or other type of underlayment under the roof covering for extra resistance to leakage.
  The word sarking is further used as part of the term scrim and sarking, a method of interior construction widely used in Australia and New Zealand in the late 19th and early 20th centuries.
  In current usage in Australia, sarking refers to a laminated aluminium foil layer, or reflective foil laminate, that is installed on the roof trusses, beneath the battens, supporting a tile or metal deck roof. It acts as additional radiative and convective insulation and provides a condensation barrier.
