Widespread adoption of one possible solution, exterior insulation of masonry walls, will require demonstration projects that prove the feasibility of the techniques and evaluate challenges. (buildingscience.com)
The thermal resistance of even thick masonry walls is far below modern code requirements: common moderate density brickwork (80 to 110 lb / ft3 or 1280 — 1760 kg / m3) can be assumed to provide an R - value from R - 0.25 to R - 0.33 per inch (k ≈ 0.43 to 0.58 W / [m · K]-RRB-. (buildingscience.com)
Payne treated the buildings as found objects, using their existing masonry walls as backdrops to the overall program.» (treehugger.com)
