An Investigation into the Resilience and Durability of High R-Value Exterior Insulated Wood Framed Walls in Cold Climates Assessed Using In-Situ Measurement and Calibrated Hygrothermal Modeling
Bibliographic record
Abstract
<p>Super-insulated building envelopes are more energy efficient than Canadian building codes require but a particular design may not be resilient when subjected to different Canadian climates. This research evaluated the hygrothermal performance of a nominal 2x6 framed assembly with 75-225 mm of exterior mineral fiber sheathing insulation in climates across Canada. Variations of the design with and without variable permeability membranes were constructed and monitored. Results from climate chamber and in-situ monitoring were used to calibrate hygrothermal simulations. The research demonstrates that variable permeability membranes do not necessarily keep a wall drier than a traditional 6 mil poly vapour barrier and that the amount of exterior insulation can play a more important role in moisture management and resilience. Results from the climate chamber, in-situ monitoring and hygrothermal simulations demonstrated that the walls performed satisfactorily and all were able to dry under typical operating conditions.</p>

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
