Button-Up Notes

John Ashton, of Ashton Thermal, gave a powerpoint presentation and showed samples of insulation and air sealing materials.

Here are margin notes from the presentation and questions:
  • It is usually not desirable to insulating heating pipes. Insulate hot and cold domestic water pipes with foam -- its a generic product so it does not matter what brand you use. Miter the corners and tape with Typar tape.
  • It is not usually advisable to insulate between a basement and the first floor. Do seal and insulate the sill & foundation joint.
  • Only wrap electric hot water tanks. Combustion-heated tanks should generally not be wrapped. Venting and fire safety are the issue.
  • Conditioned space relative humidity should be not more than 35% in the winter. Close a basement in the summer to prevent moisture condensation. Open it during dry autumn days.
  • Front-loading washers are very effective and use little water. Use cold water wash and the correct detergent.
  • Take care to properly seal chimney penetrations with the correct fire-resistant materials and high temperature caulk.
