Figure 6. Wall Assembly, Nunavik, Quebec Source: Angers (1999). Figure 7. Floor Assembly, Nunavik, Quebec Source: Angers (1999). • Floor: The floor (Figure 6) is a double system, which creates a service chase for the air ducts of an oil heating system. The thermal resistance of the double floor system is RSI-6.7 (R-38) for public buildings or RSI-5.4 (R-31) for houses. In southern Quebec, RSI-4.7 (R-27) is required for floors. • Windows: Triple-glazed windows provide thermal resistance of RSI-0.5 (R-3) as compared to double-glazed windows in southern Quebec. Window openings are reduced to a minimum. PERD-079: Task 2 - <strong>Literature</strong> <strong>Review</strong> 24
• Plumbing system: To solve condensation problems, plumbing is insulated and, depending on the building’s heating system, a glycol or warm air is used to heat pipes. • Porch: Houses include an unheated, insulated porch at the main entrance to act as an air lock to keep cold air out when the door is opened, and also to minimize condensation. Angers (1999) noted that a new approach is being tried in which building modules are prefabricated in a factory in southern Quebec and transported on barges to the north. The goal is to reduce completion costs on site. Nunavut Example: A building envelope assembly adopted by Nunavut Housing Corporation (2005) consists of the following. A similar assembly is described in the builders’ manual prepared by the ACHP (1995). • Exterior wall assembly: - total RSI-5.1 (R-29), from exterior to interior; - prefinished structural panel siding i ; - air barrier; a complete house rap system; - wood studs, 38 x 140 mm (2 x 6) at 600 mm (24 in.) on centre; - mineral wool batt, 140 mm (5½ in.), RSI-3.9 (R-22); - poly vapour barrier, 6 mil ii ; - strapping 38 x 38 mm (2 x 2) at 600 mm (24 in.) on centre; - semi-rigid insulation, 38 mm (1½ in.) RSI-1.2 (R-7); and - gypsum board, 12.7 mm (½ in.), abuse resistant, painted. • Roof assembly: Total RSI-7.7 (R-44), from exterior to interior; - metal roof; - strapping 19 x 64 mm (1 x 3) at 600 mm (24 in.) on centre; - air barrier; - plywood sheathing, 9.5 mm (3/8 in.); - joists; - mineral wool batt two layers, 150 mm (6 in.) RSI-3.9 (R-22) (fills void completely); - plywood sheathing, 12.7 mm (½ in), 3 mm (1/8 in.) gap at joints; - vapour barrier; and - gypsum board, 12.7 mm (½ in), abuse resistant, painted. • Floor insulated assembly: Total RSI-9 (R-51), from interior to exterior: - vinyl tile; - underlay (6 mm (¼ in)) over 16 mm (5/8 in.) tongue and groove plywood (glue and screw/nail to floor joists); - floor joists; - mineral wool insulation, two layers 150 mm (6 in.), RSI-3.9 (R-22) (fill void completely); - strapping 38 x 38 mm (2 x 2) perpendicular to the floor joists; PERD-079: Task 2 - <strong>Literature</strong> <strong>Review</strong> 25
