5. The St. Mary & St. Samuel Coptic Orthodox Church, a 2,973 square meter single-story place of worship in Markham, Ontario Canada
The building’s intended use and challenging design required a high level of drywall craftsmanship and skill to achieve the ambitious interior space this church demands. The project required the highest quality drywall finishes to the church's domes and high ceiling with severe, critical lighting due to massive windows.

7. Main characteristics of this project
Overall construction included: concrete
foundation/slab; structural steel; metal deck; masonry & stucco cladding;
aluminum and glazing; interior finishes; mechanical, sprinklers, and electrical
Domes in high ceiling required high quality finish (Level 5) due to severe, critical lighting
7,432 m² of VAP Plasterboard
4,459 m² of GlasRoc Exterior Sheathing
Full range of CertainTeed Finishing products – compounds, tape, corners… and, CertainTeed Insulation

8. Durable Exterior substrate to maintain the building’s longevity and structural integrity.

9. Vast interior space required wall/ceiling construction at extraordinary heights, adding to the complexity of the project.

10. Overhead ceiling plasterboard installation acted as a smooth surface for final ceiling graphics and a high degree of scrutiny due to extreme lighting that the domes and windows create.

11. Open, lofty interior space that required plasterboard skills beyond typical wall installations.

13. Key challenges (write a max. 50 words paragraph)
e.g. Budget, Time, Space, Technical challenges before and during installation/application (Development of a new solution…)
Place of worship required bright, immense and inspiring interior space
Large windows offering natural daylight demanded Level 5 plasterboard finishes
Busy parish with lots of visitors create high traffic in lobbies and hallways where walls and corners can sustain damage

Real customer success story with this project for CertainTeed:
Smith Brothers Contracting used competitor joint compound and powders.
New CertainTeed formulations were introduced to the contractor, who used them throughout this challenging project.
They continue to use CertainTeed Finishing Joint Compound and Setting Powders on other projects – successful and sustained customer conversion.
Smith Brothers also “trialed” No-Coat Corner System products on the Church and continue to use these corners on other projects.
