  14. 14. Confidential 14 Performance and Detailing Corium Precast Brick Continuous Insulation to Code** Loading of Slab Use of Slab area Penetrations of Air Vapour Barrier (4-6” of Rockwool for R18+) **R value of walls is not only way to meet performance requirements of code
  15. 15. Current Building Envelope Issues impacting choice While in the past building envelope conventions allowed standard details of traditional brick and precast, newer standards across Canada, and those that will be coming soon, make it more and more difficult. Thin cladding outside all exterior insulation cavity lend themselves more easily to these performance standards. • Insulation between studs not satisfactory any more. • Continuous AVB outside structure key to performance. • Brick impact: • Many ties piercing AVB, • possibly thermal bridges. • Installation quality key to satisfactory performance. • Brick ledges are very deep, and thermal bridges (is there a tested thermally broken brick ledge?) • Precast: • Thick insulation requirements make sandwich panels either impossible or expensive, taking up floor slab space (are they possible?) • Thermally broken cladding insulation cavities of 4-6” standard for thinner lighter weight cladding for 10 years, modelled by experts and installed across the country. 15 Make less wordy – pictures?

  20. 20. 20 Source: OBEC PTE Spring 2019 Blok-Lok Ad What’s wrong • Number of ties • Penetrations of AVB • Thermal bridges if not this tie • Thickness of insulation ie code compliance • Dependence on excellent installation
