| Abstract: |
| Explores the possibility of constructing a cold climate attic with no vents, and achieving large improvements in performance and energy savings. Venting can cause problems in cold dry climates such as allowing snow to blow in, as well as problems with the design of complex geometry roofs. If the roof sheathing is kept above the dew point temperature of the interior air vapor mix, condensation and moisture accumulation will not occur. So the ventless design will depend on installing a continuous ceiling vapour diffusion retarder/air retarder and thick ceiling insulation.
