Air sealing and insulating above a stairway ceiling – www.startinsulating.com

In older homes the drywaller and plaster installer) often did not drywall the space above a stairway ceiling because the stair ceiling created the barrier between the attic and the stairwell. Unfortunately, this creates a huge hole in the attic floor and this space is as cold as your attic during the winter months. It is difficult to properly insulate the inside of these walls and it is wasteful to fll the entire hole with cellulose insulation. The solution is to block the opening between the floor joists with paneling or foam board, and then seal ALL seams wih spray foam.
