After months of intensive glass assembly research and hundreds of mock-ups, Moed de Armas & Shannon, together with executive architect B+H Architects, developed an innovative new glass spandrel system being used to redefine the tallest building in Canada, Toronto's 72-story First Canadian Place. As the original marble cladding began to fail, MdeAS proposed replacing 45,000 aging marble panels with 5,370 specially designed glass spandrel panels. MdeAS' exhaustive research of industry-standard glass assemblies led to a custom frit-patterned white spandrel panel that meets exacting color, size, strength, performance and economic constraints.
