Tips for Keeping a Tight House

This past month our Project Manager had an opportunity to attend a seminar hosted by the  Building Science Corporation. He brought back some helpful tips for keeping a tight house this winter. Here they are in no particular order:

1. When sealing a house, you get the most bang for your buck by sealing the top of the house first.

2. The majority of heat loss (30-40%) occurs through air leakage. This could be in the form of penetrations not being sealed, lighting into the attic, etc.. The 2nd biggest area (20-25%) is through the foundation. 

3. Include a dehumidifier with all finished basement projects.

4. Whenever possible, insulate underneath the basement slab and on the outside of foundation walls.
