Thank you everybody. Blower Door Day

LucyF | Posted in Energy Efficiency and Durability on

We did our blower door test today – 94 cfm50 which translates to .48ach50. We tested at the framing stage before the installation of the dense pack cellulose insulation. I am very happy.

I just want to thank everybody for their helpful advice through this building process. I was so nervous I was peeling old caulk off our caulk guns to keep busy while the test was being set-up.

The person who did the test immediately called up some of his co-workers and I heard him say “and this is before any insulation.” He was impressed.

Thank you so much for your help.

    A sub-100 cfm/50 number is AMAZINGLY tight- hard to even measure accurately! Good show!

    Martin and Dana,

    I was very happy with the result. We sealed the outside and the inside of every stud bay, every floor/wall/ceiling connection, everywhere with high quality components - Tescon tapes, Siga tapes, prosoco joint and seam filler, canned spray foam around the windows and doors, etc.

    You two are the main people that I wanted to thank. I read every comment that ya'll post on the questions. I really appreciate your answers and amazing details, and even the patience you demonstrate in your replies.

    Thank you again.

    That's an amazing pre-insulation/drywall number. Congrats.
