The system utilizes structural 38mm x 140mm lumber framing filled with 140mm of cellulosic fibre insulation to conform with the required minimum RSI-Value of 3.87 specified in part 9 of OBC 2006. Cellulosic Fibre alone did not meet the minimum RSI-value, and so a 50mm layer of continuous, closed-cell rigid extruded polystyrene insulation was applied to the exterior layer of the system, which provides the required extra insulation, while at the same time acting as a rain screen for the air barrier system.

EXPLANATION OF WALL ASSEMBLY According to Part 3 of OBC 2012, Structures consisting of combustible structural (lumber) construction, must utilize lumber that has been pressure impregnated with Fire-Resistant chemicals, and have a Flame-Spread value of 25 or less. To meet this requirement, Wall Type 2 utilizes Pressure-Treated lumber framing and sheathing that meets the CAN/CSA 080 Series-M Preservative Standard. Structural 38mm x 140mm Lumber Framing was employed.

To meet this requirement, the wall system utilizes 140mm of Roxul, Mineral Fibre Insulation, which has a RSI-Value of 3.87, without a framing factor, and promotes the fire-safety standards outlined in Part 3 of the OBC, featuring a flame-spread value of 0 (reference cutsheet). The system was then required to utilize a layer of continuous insulation separate from the main body of insulating material. A 50mm sheet of continuous, rigid, closed-cell Extruded Polystyrene Insulation is used on the exterior side of the system, which not only insulates the assembly, but also acts as a rain screen preventing undue moisture from entering the wall. Although it is not entirely necessary, exterior grade plywood sheathing is applied between the load-bearing wall and the air barrier system – providing an extra layer of protection and moisture prevention, as well as extra structural rigidity.

According to Section 4.2 of Ashrae 90.1 and Tables 5.5 – 6, The Minimum RSI-Value for the insulated portion of the wall system is RSI – 2.29 + 1.32c.i.

EXPLANATION OF WALL ASSEMBLY Like the other assemblies, this commercial assembly is a fully drained and ventilated façade which forms the external aesthetic element of a multi-layer wall. The panels are supported by the CS1 extruded aluminum grid rather than wood furring. This system also allows air movement at the bottom and the top of the elevation ensuring air movement in the cavity between the panel and the inner wall. The ventilated façade system replicates the vertical boarding present in the other wall systems in patina copper rather than wood paneling.

1400

Panels are light gauge and roll formed, giving tight tolerance in dimensions essential when using light-gauge, flexible metals.

1200

Copper flashing is utilized alongside the copper cladding in order to avoid undue metallic reactions.

20 15

10 5

Unlike the other wall assemblies, the system utilizes 41mm x 150mm steel stud framing, but is filled with the same mineral fibre insulation present in Wall assembly 2. The stud framing is attached directly to CS1 extruded aluminum grid – which produces inevitable thermal bridging. In order to combat these bridges and meet the required insulation standards specified in Ashrae 90.1 (RSI -2.29 + 1.32c.i.) and additional 50mm of continues extruded polystyrene insulation is applied between the CS1 grid and the structural steel framing.

EXPLANATION OF WALL ASSEMBLY According to “OSB Energy-efficient Housing Construction, (1982)” the non load-bearing wall in double stud wall may experience movement. OSB sheathing between both walls was added in order to give rigidity to interior non-load bearing wall. The staggered double-stud wall minimizes thermal bridging as any potential bridges are separated by layers of insulation. The only thermal bridge that is apparent in the system comes from the OSB panels that connect the headers of both walls. The OSB panels that connect to the headers of the framing rest on top of the vapour retarder, and help protect it.

Vapour retarders are doubled up. First layer is stapled to studs. Then acoustic sealant is applied over staples and the next layer is stapled onto the acoustic sealant – this ensures that there are less openings in the vapour retarder where moisture could get through, while helping to minimize thermal bridging through staples. Cellulose is used because it has the lowest embodied energy of all popular insulation types (McGrath, Ed (1981)). It is made of 75-85% recycled paper, usually post-consumer newsprint the rest is a fire retardant like boric acid or ammonium sulphate. Cellulose is made with locally available paper; mineral insulation is usually shipped from factories far away and they use chemicals that require more energy to process and create polluting byproducts. Cellulose has the highest recycled content of any insulation material and has less embodied energy than fiberglass and other furnace produced mineral insulations. Spray applied cellulose insulation, similar to the one manufactured by Celbar, was used instead of loose fill as it will cover smaller spaces in the assembly that could allow for airflow. The spray applied cellulose has similar R-value to rock wool (seen in the other systems) or glass wool - Around RSI – 3.5 (not accounting for wall framing factor). Cellulose insulation is quite permeable, this means that if any water does get into the as-

sembly then it will distribute throughout the assembly and dry out rather than staying in one place and causing mould.

Because there air in the insulation and it is permeable – this means that it is a good noise insulator. For Subfloor used Dricore® - Because it’s raised moisture barrier covers cold, damp concrete to protect and insulates finished floors. Concrete continually releases moisture – air flow underneath prevents mould and insulates to prevent thermal bridging between slabs.

Triple glazed windows are installed to provide better insulation. According to “OSB Energy-efficient Housing Construction, (1982)” it is common to put the vapour retarder betweeen the double stud wall as long as 2/3 of the insulation is on the cold side of the vapour retarder. However, calculations proved that condensation would be present and the vapour retarder was put on the warm side of the whole assembly.

Comparisons Between Assemblies In order to provide ease of connection and assembly between wall types, the levels are ordered based on common materials and dimensions between assemblies. Wall types 1,2, and 4 all feature 38mm x 140mm structural lumber wall framing with a stud spacing of 400mm at centre. These framing walls are positioned on the same sectional plane throughout the assemblies in order to stack the assemblies on each slab evenly. The façade system is fully drained and ventilated across all four assemblies. In order to achieve this, the same dimension extruded polystyrene rain screen was applied across assemblies, therefore enabling continuous ventilated furring and cladding. The major difference between systems occurs at the top floor of the assembly, where wall type 3 was placed. The copper clad parapet is slightly offset from the wood cladding and is fully flashed to divert moisture & water from penetrating the lower air spaces.

Technical Product Information BATT INSULATION 07210* BLANKET INSULATION 07 21 16**

General Product Information:

Description & Common Applications:

ROXUL products are stone wool insulations made from basalt rock and slag. This combination results in a noncombustible product with a melting point of approximately 2150°F (1177°C), which gives it excellent fire resistance properties. ROXUL stone wool is a water repellent yet vapour permeable material.

ROXUL COMFORTBATT™ R10, R14, R22, R24, R28 & R32 are stone wool insulation products designed as a thermal insulation for wood and steel frame construction. This semirigid batt has a unique flexible edge designed to compress as the batt is inserted into walls, attics, ceiling and floor frames. The flexible edge springs back, expanding the batt against the frame studs to give a complete fill. COMFORTBATT compensates for normal variations in stud centres caused by distortion or warping. The special flexible characteristic at the insulation edge ensures the expected R-value is achieved.

Let COMFORTBATT expand to give a full fit

The friction fit created by the COMFORTBATT expansion principle means the product will perform equally well in horizontal, sloped dormer, vertical or overhead situations. The product is notable for its “stay put” ability when installed. COMFORTBATT is easier and faster to install than traditional insulation products and achieves full R-value. Tests carried out in 1993 by the National Research Council Of Canada (NRC) confirm that accurate fitting of insulation is essential to achieve R-values and to maintain thermal design requirements in practice. ROXUL COMFORTBATT has been designed with a flexible edge to ensure the best fit possible.
