"Housing throughout the Arctic has experienced severe problems with winter frost build-up and its subsequent damage to ceilings and roof insulation. In many communities it has become "normal" to replace the insulation every year, and to live with badly stained and damaged ceilings. This study looks at two proposed retro-fit systems, to eliminate or minimize attic moisture accumulation and the associated damage. Test houses in the communities of Yellowknife, Cambridge Bay, Eskimo Point and Baker Lake, N.W.T. were typical ten year old, four bedroom stick-built bungalows, with asphalt shingle sloped roofs, wood truss roof framing and an uninsulated attic space"--Executive summary, p. 1. gccst Housing gccst Northern Canada gccst Weather Ferguson, Simek, Clark Limited.
