Pre-Drywall Blower Door Tests

You Can’t Substitute Airtightness

You can’t substitute airtightness, but airtightness can lead to substitutions. Starting December 31, 2016 planning for an airtight building envelope will result in savings. Having Barrier Sciences Group (BSG) perform a pre-drywall blower door test will allow you to find air leakages early enough in the construction process to take advantage of substitutions and avoid costly repairs. BSG is a certified energy advisor dedicated to making sure your projects run smoothly from start to finish. Pre-drywall blower door tests are crucial to ensuring that the home exceeds your expectations. When air leakages are found prior to hanging drywall, there is nothing in the way of finding and fixing every single hole. You can have an airtight building envelope every time.

Plan to Save

Planning your building envelope for optimal airtightness will save you money on construction costs. If your building hits certain Air Changes per Hour targets, you can substitute costly materials and equipment with less costly alternatives. The only way to know if your building envelope is meeting those targets is by performing a pre-drywall blower door test. This makes having a pre-drywall blower door test a fundamental part of the planning process.

Time to Save

By spending a little time on a pre-drywall blower door test, you are saving a lot of time finding and repairing air leakages in the building envelope – air leakages are still easily accessible and easy to repair at this stage in construction. The more often you have a pre-drywall blower door test performed, the better you become at stopping leaks before they start.

First to Save

Starting January 2019, mandatory energy labelling will be required for all single-family homes being listed for sale, including homes that are newly constructed. Start being a leader now by catching air leakages early so your homes score high energy ratings every time. You won’t just be setting a strong foundation for your future. You will be gaining a reputation as a leader.

  • Start your homes with airtight building envelopes and utilize substitutions
