Click this link to learn more about this wall in the ENBIX wall library: https://www.enbix.ca/document/enbix-w... Summary - Construction of this assembly was again very similar to the Tier 1 2x6 Assembly. Framing consisted of two 2x4 stud walls, framed utilizing current code compliant, industry standard techniques. These walls have a 3” space between them, so a plywood or OSB spacer that is ripped to the width of the overall assembly thickness was installed to the top of the walls cap plate. This kept the walls held the correct distance apart. While building, 3” blocks were utilized to keep the two walls spread apart while securing them together. A ¾” plywood buck was installed around the perimeter of the window and door R.O. to maintain proper spacing and provide a solid R.O. surface. R-12 fibreglass batt insulation was installed in the exterior 2x4 wall cavity first. The fibreglass batts were then installed in the 3” cavity space horizontally. Installing this layer horizontally allowed the insulation to span across several stud spaces which helped hold the insulation in place the interior wall insulation is then installed. This process, especially installing the insulation in the 3” cavity space, was time consuming but very straightforward and simple. The air control layer for this assembly was the Siga Majrex Moisture Variable VB. Maintaining a continuous air control layer was achieved with this membrane along with the following materials and methods: Taping any joints and openings in the VB and taping the VB to the floor under the wall bottom plate. Airtight electrical boxes with gasket seals at the face. Foam backer rod and caulking to connect the VB to the window frame. Expanding spray foam insulation. Taping WRB to mechanical penetrations Assembly Advantages Easy to build as it was essentially just building a second wall compared to “Business as Usual” Materials used were easily accessible at a hardware or building supply store, aside from the Siga membrane and tape. WRB used was more affordable compared to the Tier 3 assembly. Did not require specialized professionals outside the norm to design or build. Building two walls with a space between significantly reduces the amount of thermal bridges compared to “Business as Usual”. The spacing between the walls can be as large or small as needed or wanted. Assembly Disadvantages Airtightness detailing was similar to the “Business as Usual Assembly” and was more challenging compared to the Tier 3 assembly as has been discussed. Lifting and moving the connected framed walls was more difficult due to the weight of the increased framing. Custom interior jamb finishing, or a custom ordered jamb extension from the window manufacturer was required. Read the full report here - https://www.enbix.ca/wp-content/uploa...
